This paper is the first to conduct an incentive-compatible experiment using real monetary payoffs to test the hypothesis of probabilistic insurance which states that willingness to pay for insurance decreases sharply in the presence of even small default probabilities as compared to a risk-free insurance contract. In our experiment, 181 participants state their willingness to pay for insurance contracts with different levels of default risk. We find that the willingness to pay sharply decreases with increasing default risk. Our results hence strongly support the hypothesis of probabilistic insurance. Furthermore, we study the impact of customer reaction to default risk on an insurer’s optimal solvency level using our experimentally obtained data on insurance demand. We show that an insurer should choose to be default-free rather than having even a very small default probability. This risk strategy is also optimal when assuming substantial transaction costs for risk management activities undertaken to achieve the maximum solvency level.
This dissertation consists of three essays, which study the implication of financial frictions in business cycles and monetary policy making. The first essay develops a Dynamic Stochastic General Equilibrium (DSGE) model to study how the instability of the banking sector can amplify and propagate business cycles. Model simulations show that in an economic down turn, in addition to credit demand contraction induced by low firm net worth, low bank capital
position can create strong credit supply contraction, and have a quantitatively significant effect on business cycle dynamics. The second essay studies the optimal Taylor-type monetary policy rules based on the model developed in the first chapter and find that with interest rate smoothing, 'leaning against the wind' can significantly dampen the procyclicality of financial distortions, and increase the welfare of the economy. The third chapter examines the role of households frugality in a financial crisis and finds that higher savings by more frugal households provide an important cushion for the fall in private investment funding.
Highlights
• Pathways for a circular economy towards the EU goals require policy support that, in turn, requires legitimacy.
• Legitimacy is often contested in the public discourse at all phases in the technological innovation system.
• Legitimacy remains poorly understood for ‘in-between’ technologies that struggle to move from the formative to the growth stage.
• The article explores legitimacy for chemical recycling primarily based on evidence from the UK, Germany, and Italy.
Abstract
The European Commission aims to increase the recycling of plastic packaging to 60% by 2025, requiring fundamental changes towards a more circular economy. Pathways for this transition require policy support that largely depends on their legitimacy in the public discourse. These normative aspects remain poorly understood for ‘in-between’ technologies, i.e., technologies that are no longer novel but struggle to move to the growth phase within the technological innovation system. Therefore, we ask: How do discourses shape technology legitimacy for in-between technologies? Drawing on the empirical example of chemical recycling, the analysis renders two principal findings. First, legitimising and delegitimising storylines present contesting views on in-between technologies regarding their technological aspects, environmental and social impacts, and economic and policy implications. Second, how discourses contribute to technology legitimacy depends on the actors and interests that drive the prevalent storylines in particular contexts.
Biodiversity loss poses a significant threat to the global economy and affects ecosystem services on which most large companies rely heavily. The severe financial implications of such a reduced species diversity have attracted the attention of companies and stakeholders, with numerous calls to increase corporate transparency. Using textual analysis, this study thus investigates the current state of voluntary biodiversity reporting of 359 European blue-chip companies and assesses the extent to which it aligns with the upcoming disclosure framework of the Task Force on Nature-related Financial Disclosures (TNFD). The descriptive results suggest a substantial gap between current reporting practices and the proposed TNFD framework, with disclosures largely lacking quantification, details and clear targets. In addition, the disclosures appear to be relatively unstandardized. Companies in sectors or regions exposed to higher nature-related risks as well as larger companies are more likely to report on aspects of biodiversity. This study contributes to the emerging literature on nature-related risks and provides detailed insights on the extent of the reporting gap in light of the upcoming standards.
Contemporary information systems make widespread use of artificial intelligence (AI). While AI offers various benefits, it can also be subject to systematic errors, whereby people from certain groups (defined by gender, age, or other sensitive attributes) experience disparate outcomes. In many AI applications, disparate outcomes confront businesses and organizations with legal and reputational risks. To address these, technologies for so-called “AI fairness” have been developed, by which AI is adapted such that mathematical constraints for fairness are fulfilled. However, the financial costs of AI fairness are unclear. Therefore, the authors develop AI fairness for a real-world use case from e-commerce, where coupons are allocated according to clickstream sessions. In their setting, the authors find that AI fairness successfully manages to adhere to fairness requirements, while reducing the overall prediction performance only slightly. However, they find that AI fairness also results in an increase in financial cost. Thus, in this way the paper’s findings contribute to designing information systems on the basis of AI fairness.
With free delivery of products virtually being a standard in E-commerce, product returns pose a major challenge for online retailers and society. For retailers, product returns involve significant transportation, labor, disposal, and administrative costs. From a societal perspective, product returns contribute to greenhouse gas emissions and packaging disposal and are often a waste of natural resources. Therefore, reducing product returns has become a key challenge. This paper develops and validates a novel smart green nudging approach to tackle the problem of product returns during customers’ online shopping processes. We combine a green nudge with a novel data enrichment strategy and a modern causal machine learning method. We first run a large-scale randomized field experiment in the online shop of a German fashion retailer to test the efficacy of a novel green nudge. Subsequently, we fuse the data from about 50,000 customers with publicly-available aggregate data to create what we call enriched digital footprints and train a causal machine learning system capable of optimizing the administration of the green nudge. We report two main findings: First, our field study shows that the large-scale deployment of a simple, low-cost green nudge can significantly reduce product returns while increasing retailer profits. Second, we show how a causal machine learning system trained on the enriched digital footprint can amplify the effectiveness of the green nudge by “smartly” administering it only to certain types of customers. Overall, this paper demonstrates how combining a low-cost marketing instrument, a privacy-preserving data enrichment strategy, and a causal machine learning method can create a win-win situation from both an environmental and economic perspective by simultaneously reducing product returns and increasing retailers’ profits.
Unconventional green

We analyze the effects of the PEPP (Pandemic Emergency Purchase Programme), the temporary quantitative easing implemented by the ECB immediately after the burst of the Covid-19 pandemic. We show that the differences in aim, size and flexibility with respect to the traditional Corporate Sector Purchase Programme (CSPP) were able to significantly involve, in addition to the directly targeted bonds, also the green bond segment. Via a standard difference- in-differences model we estimate that the yield on green bonds declined by more than 20 basis points after the PEPP. In order to take into account also the differences attributable to the eligibility to the programme, we employ a triple difference estimator. Bonds that at the same time were green and eligible benefitted of an additional premium of 39 basis points.
By focusing on the cost conditions at issuance, I find that not only the Covid-19 pandemic effects were different across bonds and firms at different stages, but also that the market composition was significantly affected, collapsing on investment- grade bonds, a segment in which the share of bonds eligible to the ECB corporate programmes strikingly increased from 15% to 40%. At the same time the high-yield segment shrunk to almost disappear at 4%. In addition to a market segmentation along the bond grade and the eligibility to the ECB programmes, another source of risk detected in the pricing mechanism is the weak resilience to pandemic: the premium requested is around 30 basis points and started to be priced only after the early containment actions taken by the national authorities. On the contrary, I do not find evidence supporting an increased risk for corporations headquartered in countries with a reduced fiscal space, nor the existence of a premium in favour of green bonds, which should be the backbone of a possible “green recovery”.
We assess the degree of market fragmentation in the euro-area corporate bond market by disentangling the determinants of the risk premium paid on bonds at origination. By looking at over 2,400 bonds we are able to isolate the country-specific effects which are a suitable indicator of the market fragmentation. We find that, after peaking during the sovereign debt crisis, fragmentation shrank in 2013 and receded to pre-crisis levels only in 2014. However, the low level of estimated market fragmentation is coupled with a still high heterogeneity in actual bond yields, challenging the consistency of the new equilibrium.
We analyze the risk premium on bank bonds at origination with a special focus on the role of implicit and explicit public guarantees and the systemic relevance of the issuing institutions. By looking at the asset swap spread on 5,500 bonds, we find that explicit guarantees and sovereign creditworthiness have a substantial effect on the risk premium. In addition, while large institutions still enjoy lower issuance costs linked to the TBTF framework, we find evidence of enhanced market disciple for systemically important banks which face, since the onset of the financial crisis, an increased premium on bond placements.
Chen and Zadrozny (1998) developed the linear extended Yule-Walker (XYW) method for determining the parameters of a vector autoregressive (VAR) model with available covariances of mixed-frequency observations on the variables of the model. If the parameters are determined uniquely for available population covariances, then, the VAR model is identified. The present paper extends the original XYW method to an extended XYW method for determining all ARMA parameters of a vector autoregressive moving-average (VARMA) model with available covariances of single- or mixed-frequency observations on the variables of the model. The paper proves that under conditions of stationarity, regularity, miniphaseness, controllability, observability, and diagonalizability on the parameters of the model, the parameters are determined uniquely with available population covariances of single- or mixed-frequency observations on the variables of the model, so that the VARMA model is identified with the single- or mixed-frequency covariances.
Linear rational-expectations models (LREMs) are conventionally "forwardly" estimated as follows. Structural coefficients are restricted by economic restrictions in terms of deep parameters. For given deep parameters, structural equations are solved for "rational-expectations solution" (RES) equations that determine endogenous variables. For given vector autoregressive (VAR) equations that determine exogenous variables, RES equations reduce to reduced-form VAR equations for endogenous variables with exogenous variables (VARX). The combined endogenous-VARX and exogenous-VAR equations comprise the reduced-form overall VAR (OVAR) equations of all variables in a LREM. The sequence of specified, solved, and combined equations defines a mapping from deep parameters to OVAR coefficients that is used to forwardly estimate a LREM in terms of deep parameters. Forwardly-estimated deep parameters determine forwardly-estimated RES equations that Lucas (1976) advocated for making policy predictions in his critique of policy predictions made with reduced-form equations.
Sims (1980) called economic identifying restrictions on deep parameters of forwardly-estimated LREMs "incredible", because he considered in-sample fits of forwardly-estimated OVAR equations inadequate and out-of-sample policy predictions of forwardly-estimated RES equations inaccurate. Sims (1980, 1986) instead advocated directly estimating OVAR equations restricted by statistical shrinkage restrictions and directly using the directly-estimated OVAR equations to make policy predictions. However, if assumed or predicted out-of-sample policy variables in directly-made policy predictions differ significantly from in-sample values, then, the out-of-sample policy predictions won't satisfy Lucas's critique.
If directly-estimated OVAR equations are reduced-form equations of underlying RES and LREM-structural equations, then, identification 2 derived in the paper can linearly "inversely" estimate the underlying RES equations from the directly-estimated OVAR equations and the inversely-estimated RES equations can be used to make policy predictions that satisfy Lucas's critique. If Sims considered directly-estimated OVAR equations to fit in-sample data adequately (credibly) and their inversely-estimated RES equations to make accurate (credible) out-of-sample policy predictions, then, he should consider the inversely-estimated RES equations to be credible. Thus, inversely-estimated RES equations by identification 2 can reconcile Lucas's advocacy for making policy predictions with RES equations and Sims's advocacy for directly estimating OVAR equations.
The paper also derives identification 1 of structural coefficients from RES coefficients that contributes mainly by showing that directly estimated reduced-form OVAR equations can have underlying LREM-structural equations.
Having a gatekeeper position in a collaborative network offers firms great potential to gain competitive advantages. However, it is not well understood what kind of collaborations are associated with such a position. Conceptually grounded in social network theory, this study draws on the resource-based view and the relational factors view to investigate which types of collaboration characterize firms that are in a gatekeeper position, which ultimately could improve firm performance in subsequent periods. The empirical analysis utilizes a unique longitudinal data set to examine dynamic network formation. We used a data crawling approach to reconstruct collaboration networks among the 500 largest companies in Germany over nine years and matched these networks with performance data. The results indicate that firms in gatekeeper positions often engage in medium-intensity collaborations and less likely weak-intensity collaborations. Strong-intensity collaborations are not related to the likelihood of being a gatekeeper. Our study further reveals that a firm's knowledge base is an important moderator and that this knowledge base can increase the benefits of having a gatekeeper position in terms of firm performance.
I propose a dynamic stochastic general equilibrium model in which the leverage of borrowers as well as banks and housing finance play a crucial role in the model dynamics. The model is used to evaluate the relative effectiveness of a policy to inject capital into banks versus a policy to relieve households of mortgage debt. In normal times, when the economy is near the steady state and policy rates are set according to a Taylor-type rule, capital injections to banks are more effective in stimulating the economy in the long-run. However, in the middle of a housing debt crisis, when households are highly leveraged, the short-run output effects of the debt relief are more substantial. When the zero lower bound (ZLB) is additionally considered, the debt relief policy can be much more powerful in boosting the economy both in the short-run and in the longrun. Moreover, the output effects of the debt relief become increasingly larger, the longer the ZLB is binding.
Die Öffnung des deutschen Bilanzrechts bewirkt eine zunehmende Anwendungsbreite von internationalen Rechnunungslegungsnormen (wie insbesondere der US-GAAP und der IAS) für deutsche Rechtsanwender;1 die heterogenen Normtypen und die – damit einhergehend – unterschiedlichen ökonomischen Eigenschaften dieser Normen erfordern für einen sinnvollen Rechnungslegungsvergleich eine komparative Rechnungslegungstheorie. Eine Besinnung auf die ökonomische Theorie ist – auch ausgelöst durch die Internationalisierung der Rechnungslegung – hier grundsätzlich festzustellen,2 wie auch das moderne deutsche Bilanzrecht seine heutige Prägung durch die ökonomische Theorie – und nicht vornehmlich durch die Anwender – erhielt.3 Es ist das Ziel des Aufsatzes, einen Beitrag zu einer institutionenökonomischen Theorie der Rechnungslegung zum Zweck der Bestimmung von Informationsinhalten und Gewinnansprüchen sowie zur vergleichenden Rechnungslegungstheorie zu leisten. In einem ersten Hauptteil (2) wird im folgenden – auf dem institutionenökonomischen Forschungsprogramm aufbauend – skizziert, welche Bedeutung Institutionen im Rahmen des Nutzenkalküls von Entscheidern zuzumessen ist; danach werden die einzelnen für eine vergleichende Rechnungslegung relevanten Institutionsarten typisiert (in formale und informelle Regeln) sowie deren Attribute im individuellen Zielstromkalkül eingeführt (nämlich Prädikate der Manipulationsfreiheit und Prädikate der Entscheidungsverbundenheit). Das Verhältnis der Institutionen zueinander wird im folgenden Abschnitt (3) anhand eines rechtlich geprägten und eines ökonomischen Systemverständnisses entwickelt. Es wird gezeigt, daß beide Systembegriffe auf einer Nichtadditivität der sie konstituierenden Institutionen gründen, die den qualitativen Vergleich unterschiedlicher Systeme erschweren; man überschätzt hingegen die Unterschiede zwischen juristischem und ökonomischem Systemverständnis: beide sind funktionsähnlich. Im letzten Hauptteil (4) werden schließlich vor dem Hintergrund einer gestaltenden Theorie die hierfür relevanten Teilbereiche (Sub-Systeme) der Rechnungslegungsordnung vorgestellt sowie einzelne Publizitätsnormen funktional ausgelegt. Der Beitrag schließt mit zusammenfassenden Thesen (5).
Mängel bei der Abschlußprüfung : Tatsachenberichte und Analysen aus betriebswirtschaftlicher Sicht
(2001)
Unternehmenskrisen, „überraschende“ zumal, standen am Anfang der gesetzlichen Normierung der Abschlußprüfung in Deutschland. Es entspricht daher einem legitimen Anliegen von Öffentlichkeit und Fachwelt, die herrschende Maßstäblichkeit der Qualität von Abschlußprüfungen und die Glaubwürdigkeit4 von Abschlußprüfern insbesondere dann in gesteigertem Maße als Problem zu begreifen, wenn den gesetzlichen Schutzzwecken und Schutznormen der etablierten Abschlußprüfung zum Trotz Unternehmen in eine Krise geraten: Denn innerhalb der institutionellen Mechanismen ihrer Früherkennung – eines funktionalen Teils des deutschen Systems von corporate governance – gilt die Pflichtprüfung mit Recht als pivotales Element. Vieles an festzustellender Kritik mag hierbei einem der Komplexität der zu verhandelnden Sachzusammenhänge unüberbrückbaren Laienverständnis geschuldet sein; manches aber ist sicherlich erklärlich durch verbesserbare gesetzliche Vorschriften, zu lösende theoretische (ökonomische und rechtswissenschaftliche) Problemstellungen und eine zu fördernde gute Berufspraxis. Jüngste fragliche Mängel der Abschlußprüfung geben den Anlaß zu vorliegenden Tatsachenberichten und betriebswirtschaftlichen Analysen. Die getroffene Auswahl der Unternehmen ist hierbei ebenso willkürlich wie die der betroffenen Wirtschaftsprüfungsgesellschaften – nicht zufällig ist indes die Auswahl der betriebswirtschaftlichen Grundprobleme: Betreffen diese doch wesentliche Erwartungen an die Abschlußprüfung, die offenbar so regelmäßig enttäuscht wurden, daß selbst in Regierungsbegründungen von Gesetzesvorlagen nunmehr eine „sog. Erwartungslücke“5 bemüht wird. Die Erwartungslücken ergeben sich hierbei insbesondere aus der Vorstellung, daß (a) der gesetzliche Pflichtprüfer bei einer ordnungsmäßigen Prüfung zwingend doloses Handeln aufzudecken habe, daß (b) bilanzielle Wertansätze hinreichend zuverlässige Größen bilden, die über die Vermögenslage des Unternehmens berichten und schließlich (c) die Prüfung der tatsächlichen wirtschaftlichen Lage des Unternehmens und die Unterrichtung hiervon in Prüfungsbericht und Bestätigungsvermerk eine Selbstverständlichkeit der Pflichtprüfung sei. Diesen Erwartungen folgt der Gang der Untersuchung.
Wie lässt sich das anthropologische Fundament des Ordoliberalismus und der Sozialen Marktwirtschaft beschreiben? Welche Prämissen liegen ihm zugrunde? Ist ein derartiges Menschenbild überhaupt noch zeitgemäß? Welchen Gefahren ist es ausgesetzt und welche institutionellen Vorkehrungen lassen sich treffen? Diese und andere Fragen stehen im Mittelpunkt des nachfolgenden Essays. Dieser ist dabei wie folgt gegliedert: Das zweite Kapitel analysiert die anthropologischen Grundlagen des Ordoliberalismus. Ein Schwerpunkt liegt dabei auf dem kantischen ‚Programm der Freiheit als Autonomie‘. Das darauf folgende dritte Kapitel thematisiert mögliche Gefahrenpotenziale für eben jenes ordoliberale Menschenbild. Hierbei werden insbesondere die Vermachtung der Wirtschaft und die Instrumentalisierung und Funktionalisierung der Wissenschaft eingehender untersucht. Im vorletzten Kapitel schließlich werden die häufig vorgeschlagenen institutionellen Vorkehrungen kritisch evaluiert. Wichtige Beiträge hierzu stammen aus der Feder von Röpke (Clercs und Nobilitas naturalis) und Hayek (Zwei-Kammern-Verfassungsmodell).
The first part of the following paper deals with varying points of criticism forwarded against Ordoliberalism. Here, it is not the aim to directly falsify each argument on its own; rather, the author tries to give a precise overview of the spectrum of critique. The second section picks out one argument of critical review – namely that the ordoliberal concept of the state is somewhat elitist and grounded on intellectual experts. Based on the previous sections, the final part differentiates two kinds of genesis of norms: an evolutionary and an elitist one – both (latently) present within Ordoliberalism. In combination with the two-level differentiation between individual and regulatory ethics, the essay allows for a distinction between individual-ethical norms based on an evolutionary genesis of norms and regulatory-ethical norms based on an elitist understanding of norms. A by-product of the author’s argument is a (further) demarcation within neoliberalism.
Based on Foucault’s analysis of German Neoliberalism and his thesis of ambiguity, the following paper draws a two-level distinction between individual and regulatory ethics. The individual ethics level – which has received surprisingly little attention – contains the Christian foundation of values and the liberal-Kantian heritage of so called Ordoliberalism – as one variety of neoliberalism. The regulatory or formal-institutional ethics level on the contrary refers to the ordoliberal framework of a socio-economic order. By differentiating these two levels of ethics incorporated in German Neoliberalism, it is feasible to distinguish dissimilar varieties of neoliberalism and to link Ordoliberalism to modern economic ethics. Furthermore, it allows a revision of the dominant reception of Ordoliberalism which focuses solely on the formal-institutional level while mainly neglecting the individual ethics level.
June 4th, 2013 marks the formal launch of the third generation of the Equator Principles (EP III) and the tenth anniversary of the EPs – enough reasons for evaluating the EPs initiative from an economic ethics and business ethics perspectives. In particular, this essay deals with the following questions: What are the EPs and where are they going? What has been achieved so far by the EPs? What are the strengths and weaknesses of the EPs? Which necessary reform steps need to be adopted in order to further strengthen the EPs framework? Can the EPs be regarded as a role-model in the field of sustainable finance and CSR? The paper is structured as follows: The first chapter defines the term EPs and introduces the keywords related to the EPs framework. The second chapter gives a brief overview of the history of the EPs. The third chapter discusses the Equator Principles Association, the governing, administering, and managing institution behind the EPs. The fourth chapter summarizes the main features and characteristics of the newly released third generation of the EPs. The fifth chapter critically evaluates the EP III from an economic ethics and business ethics perspectives. The paper concludes with a summary of the main findings.
Die Dissertation gliedert sich in zwei Teile – einen methodisch-wissenschaftstheoretischen bzw. biografisch-dogmenhistorischen und einen wirtschaftsethischen Bereich. Beide Abschnitte sind wechselseitig miteinander verzahnt. Im ersten Teil geht es vorwiegend um biografische und theoriegeschichtliche Fragestellungen. Der erste Aufsatz – On the Affiliation of Phenomenology and Ordoliberalism – beschäftigt sich mit dem wechselseitigen Einfluss von Husserl, Rudolf und Walter Eucken. Der erste Aufsatz – On the Affiliation of Phenomenology and Ordoliberalism – beschäftigt sich mit dem wechselseitigen Einfluss von Husserl, Rudolf und Walter Eucken. Dabei wird eine Drei-Ebenen-Unterscheidung vorgenommen: Einflüsse lassen sich demnach nicht nur auf der biografischen, sondern gleichfalls auf der wissenschaftstheoretischen und sozialphilosophischen Ebene ausmachen. Dennoch ist Vorsicht geboten, denn der Einfluss der Phänomenologie auf das Werk Walter Euckens sollte nicht überbetont werden, in dem Sinne, dass man Eucken als angewandten Phänomenologen und die Husserlsche Phänomenologie als Metatheorie des Ordoliberalismus darstellt. Vielmehr ist von einem eklektischen Denkmuster in den Schriften Euckens auszugehen, das maßgeblich vom Werk seines Vaters beeinflusst wurde (d.i., Walter Eucken als Rudolf Euckenianer) – und dies sowohl im Bereich der Wissenschaftstheorie und Methodik als auch im Kontext des sozialphilosophischen Topos der Gesellschaftskrisis. Der zweite Aufsatz – An Ordoliberal Interpretation of Adam Smith – geht den Parallelen im Denken Adam Smiths und Euckens nach. Auffallend ist, dass Eucken Smith meist im Zusammenhang mit seiner Kritik am laissez faire- respektive Paläoliberalismus zitiert. Dabei ist seine Bezugnahme auf Smith von verzerrten Stereotypen geprägt – und dies obwohl es einige bemerkenswerte Parallelen nicht nur zwischen Eucken und Smith, sondern auch zwischen Smith und Kant gibt. Der Übergang vom sogenannten Paläo- bzw. klassischen Liberalismus hin zum Ordoliberalismus ist somit gradueller, nicht jedoch revolutionärer Art. Im Mittelpunkt des zweiten Hauptteils stehen wirtschaftsethische Themenstellungen, die eine große Affinität zum Forschungsprogramm des Exzellenzclusters 'Die Herausbildung normativer Ordnungen' aufweisen. Dabei geht es wesentlich um die Herausarbeitung des ethischen Gehalts und der stark normativen Komponenten des Ordoliberalismus. Die ersten Essays im zweiten Teilbereich der Dissertation beziehen sich primär auf Eucken und die Freiburger Schule. Die letzten beiden Aufsätze jedoch sind bestrebt, über Eucken hinauszugehen und den Ordoliberalismus i.e.S. um den Soziologischen Neoliberalismus bzw. den Wirtschafts- und Sozialhumanismus Rüstows und Röpkes zu erweitern. Die Aufsätze 'Über die normativen Implikationen des Ordoliberalismus für die moderne Wirtschaftsethik' und 'On the Economic Ethics of Walter Eucken' geben dem Leser einen Überblick über die Wirtschaftsethik der Freiburger Schule im Allgemeinen und Walter Euckens im Besonderen. Dabei wird insbesondere das ordoliberale Staats- sowie das (in der kantischen Tradition stehende) Freiheitsverständnis herausgearbeitet und der Versuch unternommen, Eucken für die moderne Wirtschaftsethik anschlussfähig zu machen. Als Ergebnis wird Euckens Ordoliberalismus, dem es um ein ausgewogenes Verhältnis von Eigeninteresse und Gemeinwohl und die Realisierung des Ideals einer funktionsfähigen und menschenwürdigen Gesellschaftsordnung geht, im Spannungsfeld von Homannscher Moralökonomik und Ulrichs Integrativer Wirtschaftsethik porträtiert. Ergänzt wird dieser Einblick in die ordoliberale Wirtschaftsethik durch das Kapitel 'Von Hayek and Ordoliberalism on Justice', das die Gerechtigkeitskonzeptionen Euckens, Rüstows und Röpkes mit derjenigen von von Hayek kontrastiert. Derart werden u.a. die Unterschiede zwischen Ordoliberalismus und Evolutorischem Liberalismus deutlich. Das Kapitel 'Individual versus Regulatory Ethics: An Economic-Ethical and Theoretical-Historical Analysis of German Neoliberalism' untersucht im Anschluss an Foucaults ‚Ambiguitätsthese‘ das Verhältnis von Individual- und Ordnungsethik und kommt zu dem Ergebnis, dass es die Besonderheit des Ordoliberalismus ist, eine weitreichende, integrative Einheit beider Ebenen vorzunehmen. Aufbauend auf der Unterscheidung von Individual- und Ordnungsethik werden im vorletzten Kapitel – 'Ordoliberalism and the Evolution of Norms' – schließlich die divergierenden Normengenese-Prozesse im Ordoliberalismus einer Analyse unterzogen. Das verblüffende Resultat lautet, dass im Ordoliberalismus zwei unterschiedliche Arten der Entstehung von Normen nebeneinander existieren – eine kulturell-evolutionäre und eine elitär-expertokratische. Mithilfe dieser Unterscheidung ist eine weitere Differenzierung zwischen von Hayek und dem Ordoliberalismus möglich. Das letzte Kapitel – Beyond Ordoliberalism? – fasst zentrale Kritikpunkte am Ordoliberalismus noch einmal zusammen und geht der Frage nach, inwiefern es realistisch erscheint, auf eine Renaissance eines aktualisierten Ordoliberalismus zu hoffen?

Im Mittelpunkt des Gutachtens stehen die anthropologischen Grundlagen, das wirtschaftsethische Fundament und das Menschenbild der Sozialen Marktwirtschaft. Die Leitlinien des Wittenberg-Prozesses der Chemie-Sozialpartner dienen dabei als argumentative Grundstruktur. Ziel der Arbeit ist es, aufzuzeigen, dass die CSSA und der Wittenberg-Prozess auf den normativen und wirtschaftsethischen Prämissen der (originären) Sozialen Marktwirtschaft ruhen und die Sozialpartnerschaft der chemischen Industrie ein wichtiger Baustein ist auf dem Weg hin zu einer Neubegründung und Renaissance der Sozialen Marktwirtschaft vor dem Hintergrund der Globalisierung. Folgende Hypothesen sollen dabei eingehender untersucht werden: 1. Fundamental für die Wirtschaftsethik der Sozialen Marktwirtschaft ist die Unterscheidung von Individual, Unternehmens-und Ordnungsethik. 2. Das Freiheitsverständnis der Sozialen Marktwirtschaft enthält sowohl negative (im Sinne der Abwesenheit von Willkür und Zwang) als auch positive Momente (im Sinne von rationaler Selbstbestimmung und kantischer Autonomie). Darüber hinaus inkorporiert es die aus der Konstitutionenökonomik bekannten Prinzipien der Diskriminierungs und Privilegienfreiheit. 3. Das Gerechtigkeitsverständnis der Sozialen Marktwirtschaft ist synkretistisch und eklektisch; es verbindet kommutative mit distributiven Gerechtigkeitselementen. 4. Der Homo oeconomicus ist kein(!) Bestandteil der Wirtschaftsethik der Sozialen Marktwirtschaft. Diese weist vielmehr Parallelen zur Heuristik der Kulturellen Ökonomik – dem sogenannten Homo culturalis – auf. 5. Eine bedeutende Funktion innerhalb der Sozialen Marktwirtschaft kommt der Sozialpartnerschaft zu. Diese leistet einen wichtigen Beitrag zur Stärkung der sozioökonomischen Teilhabe und Inklusion auf der unternehmensethischen Ebene.
Freiburg School of Law and Economics, Freiburg (Lehrstuhl-)Tradition and the Genesis of Norms
(2014)
The paper analyzes the parallels and differences between the Freiburg School of Law and Economics represented by the works of Eucken (and Röpke) and the Freiburg (Lehrstuhl-)Tradition represented by the works of Hayek and Vanberg. The parallels are illustrated by making use of the constitutional economics concepts Ordnungspolitik (i.e., order of rules/choices over rules) as well as freedom of privileges and discrimination. The differences, which have received surprisingly little attention, include the following aspects: 1. philosophy of science and epistemology, 2. genesis of norms, and 3. political philosophy. The paper tackles these issues in three steps. The second chapter presents Vanberg’s constitutional economics theory with special emphasis on the concepts of citizen sovereignty and normative individualism. The third chapter reviews the ordoliberal concepts of science and the state which are – to a certain degree – elitist and expertocratic, that is, they rely to a considerable degree on intellectual experts (in particular, scientists) being part of the societal elite. The fourth chapter differentiates two kinds of genesis of norms: an evolutionary one and an elitist-expertocratic one allowing for a differentiation between Eucken’s and Röpke’s Ordoliberalism on the on the hand and Vanberg’s Hayekian -- and Buchanan-style constitutional economics approach on the other hand. The paper ends with a summary of the main findings.
Following Foucault's analysis of German Neoliberalism (Ordoliberalism) and his thesis of ambiguity, this paper introduces a two-level distinction between individual and regulatory ethics. In particular, its aim is to reassess the importance of individual ethics in the conceptual framework of Ordoliberalism. The individual ethics of Ordoliberalism is based on the heritage of Judeo-Christian values and the Kantian individual liberty and responsibility. The regulatory or formal-institutional ethics of Ordoliberalism which has so far received most attention on the contrary refers to the institutional and legal framework of a socio-economic order. By distinguishing these two dimensions of ethics incorporated in German Neoliberalism, it is feasible to distinguish different varieties of neoliberalism and to link Ordoliberalism to modern economic ethics.
Variations and disparities between von Hayek and Ordoliberalism can be detected on diverse levels: 1. philosophy of science; 2. setting dissimilar priorities; 3. social philosophy; 4. genesis of norms; and, 5. notion of freedom. Therefore, it is possible to make an important distinction within neoliberalism itself, which contains at least two factions: von Hayek’s evolutionary liberalism, and German Ordoliberalism. The following essay not only takes the neoliberal separation of different varieties as granted; it proceeds further. It focuses on the topic of justice and elaborates the (slightly) differing conceptions of justice within neoliberalism. Thus, the specific contribution of the paper is that it adds a sixth dimension of differences (which is highly interconnected with the differing conceptions of genesis of norms). In this paper, I emphasize the (often neglected) subtle differences between von Hayek, Eucken, Röpke, and Rüstow, with special emphasis on their theories of justice. In this regard, I focus not only on Eucken and von Hayek; in addition, I include the concepts of justice developed by Rüstow and Röpke, as well, and, in consequence, broaden the perspective incorporating Eucken as a member of the Freiburg School of Law and Economics, and Rüstow and Röpke as representatives of Ordoliberalism in the wider sense. The paper tackles these topics in three steps. After briefly examining and discussing the existing literature and providing a literature overview on the decade-long debate on von Hayek and Ordoliberalism, I then describe von Hayek’s conception of commutative justice; particularly, justice of rules and procedures (rather than end-state justice). Then, I examine Eucken’s, Rüstow’s, and Röpke’s theories of justice, which consist of a mixture of commutative and distributive justice. Then, I draw a comparison between the ideas of justice developed by Eucken, Röpke, Rüstow, and von Hayek. The essay ends with a summary of my main findings.
4 June 2013 marked the formal launch of the third generation of the Equator Principles (EP III) and the tenth anniversary of the EPs – enough reasons for evaluating the EPs initiative from an economic ethics and business ethics perspective. This chapter deals with the following questions: What has been achieved so far by the EPs? Which reform steps need to be adopted to further strengthen the EPs framework? Can the EPs be regarded as a role model in the field of sustainable finance and CSR? The first part explains the term EPs and introduces the keywords related to the EPs framework. The second part summarises the main characteristics of the newly-released third generation of the EPs. The third part critically evaluates EP III from an economic ethical and business ethics perspective. The chapter concludes with a summary of the main findings.
As recent newspaper headlines show the topic of patents/patent laws is still heavily disputed. In this paper I will approach this topic from a theoretical-historical and history of economic thought-perspective. In this regard I will link the patent controversy of the nineteenth century with Walter Eucken’s Ordoliberalism – a German version of neoliberalism. My paper is structured as follows: The second chapter provides the reader with a historical introduction. At the heart of this paragraph are the controversy and discourse on patent laws in nineteenth century Europe as well as the pro and contra arguments presented by the anti-patent/free-trade movement respectively by the advocates of patent protection. The focus of my paper is on the struggle for the protection of inventions and innovations in nineteenth century Germany, since Walter Eucken, main representative of the Freiburg School of Law and Economics, picks up the counter-arguments presented in the national debate and in particular by the Kongress deutscher Volkswirthe. The third chapter deals intensively with the question whether patent laws are just ‘nonsense upon stilts’ from an ordoliberal perspective. Here, Eucken’s arguments against the current patent system are elaborated in great detail. The paper ends with a summary of my main findings.
2008/9 sees the 60th anniversary of the German economic and currency reform of June 20, 1948, and the adoption of the Grundgesetz on May 23, 1949, which committed the country to the ideals of a socially committed market economy. Both of these events are important points along the path taken by the Federal Republic of Germany to reach the system of a social market economy. Since the term, Social Market Economy is often used in several different contexts and sometimes to mean contradictory things, we must ask: what exactly does the term social market economy entail? What economic-ethical ideas and theories are behind it? This paper will trace the origins of the social market economy (chapter 2) and explain the central characteristics of the Freiburg School of Economics (chapter 3), one of the main pillars of the social market economy. Central to this paper is the oeuvre of Walter Eucken, one of the leading representatives of the ordoliberal Freiburg School. The aim is to identify socio-political factors of influence and inspiration on his theory of economic policy (chapter 4) and evaluate similarities to the works of Kant, Smith and other economic philosophers. Chapter 5 will seek to elucidate Eucken’s “Program of Liberty”. We shall also allow ourselves a slight diversion to elaborate on the parallels between this work and Kant’s understanding of freedom and autonomy. Chapter 6 deals with Eucken’s dual requirements of an economic and social order (i.e. functioning and humane socio-economic order). In chapter 7, we seek to answer – with considerable reference to Adam Smith – to what extent it can be assumed that self-interest and the common good are mutually compatible. This paper concludes with a few remarks about the topicality of ordoliberalism in relation to modern, German-speaking economic ethics (chapter 8).

By computing a volatility index (CVX) from cryptocurrency option prices, we analyze this market’s expectation of future volatility. Our method addresses the challenging liquidity environment of this young asset class and allows us to extract stable market implied volatilities. Two alternative methods are considered to compute volatilities from granular intra-day cryptocurrency options data, which spans over the COVID-19 pandemic period. CVX data therefore capture ‘normal’ market dynamics as well as distress and recovery periods. The methods yield two cointegrated index series, where the corresponding error correction model can be used as an indicator for market implied tail-risk. Comparing our CVX to existing volatility benchmarks for traditional asset classes, such as VIX (equity) or GVX (gold), confirms that cryptocurrency volatility dynamics are often disconnected from traditional markets, yet, share common shocks.

Editorial : economic competence and financial literacy of young adults – status and challenges
(2016)
In modern society, the ability to deal with financial and economic matters is becoming increasingly important. This is true for both professionals – e.g., in the investment and banking sectors – and for individuals responsible for managing their financial and economic affairs in everyday life (Aprea et al., in press). This ability is generally described as economic competence, economic literacy or financial literacy. Despite the importance of these constructs, there is still a lack of clarity regarding the exact definitions, and specifically, which components they cover in detail. Furthermore, the terms economic competence and financial literacy are only loosely coupled. Economic competence is usually considered to be more comprehensive than financial literacy. However, recent research on financial literacy has followed a broader approach as well. ...
We examine the dynamics of assets under management (AUM) and management fees at the portfolio manager level in the closed-end fund industry. We find that managers capitalize on good past performance and favorable investor perception about future performance, as reflected in fund premiums, through AUM expansions and fee increases. However, the penalties for poor performance or unfavorable investor perception are either insignificant, or substantially mitigated by manager tenure. Long tenure is generally associated with poor performance and high discounts. Our findings suggest substantial managerial power in capturing CEF rents. We also document significant diseconomies of scale at the manager level.
This dissertation introduces in chapter 1 a new comparative approach to model-based research and policy analysis by constructing an archive of business cycle models. It includes many well-known models used in academia and at policy institutions. A computational platform is created that allows straightforward comparisons of models’ implications for monetary and fiscal stabilization policies. Chapter 2 applies business cycle models to forecasting. Several New Keynesian models are estimated on historical U.S. data vintages and forecasts are computed for the five most recent recessions. The extent of forecast heterogeneity for models and professional forecasts is analysed. Chapter 3 extends the forecasting analysis to a long sample and to the evaluation of density forecasts. Weighted forecasts are computed using a variety of weighting schemes. The accuracy of forecasts is evaluated and compared to professional forecasts and forecasts from nonstructural time series methods. Chapter 4 adds a new feature to existing business cycle models. Specifically, a medium-scale New Keynesian model is constructed that allows for strategic complementarities in price-setting. The role of trade integration for monetary policy transmission is explored. A new dimension of the exchange rate channel is highlighted by which monetary policy directly impacts domestic inflation. Chapter 5 tests whether simple symmetric monetary policy rules used in most business cycle models are a sufficient description of reality. I use quantile regressions to estimate policy parameters and find asymmetric reactions to inflation, the output gap and past interest rates.
This paper investigates the accuracy of point and density forecasts of four DSGE models for inflation, output growth and the federal funds rate. Model parameters are estimated and forecasts are derived successively from historical U.S. data vintages synchronized with the Fed’s Greenbook projections. Point forecasts of some models are of similar accuracy as the forecasts of nonstructural large dataset methods. Despite their common underlying New Keynesian modeling philosophy, forecasts of different DSGE models turn out to be quite distinct. Weighted forecasts are more precise than forecasts from individual models. The accuracy of a simple average of DSGE model forecasts is comparable to Greenbook projections for medium term horizons. Comparing density forecasts of DSGE models with the actual distribution of observations shows that the models overestimate uncertainty around point forecasts.
The paper illustrates based on an example the importance of consistency between the empirical measurement and the concept of variables in estimated macroeconomic models. Since standard New Keynesian models do not account for demographic trends and sectoral shifts, the authors proposes adjusting hours worked per capita used to estimate such models accordingly to enhance the consistency between the data and the model. Without this adjustment, low frequency shifts in hours lead to unreasonable trends in the output gap, caused by the close link between hours and the output gap in such models.
The retirement wave of baby boomers, for example, lowers U.S. aggregate hours per capita, which leads to erroneous permanently negative output gap estimates following the Great Recession. After correcting hours for changes in the age composition, the estimated output gap closes gradually instead following the years after the Great Recession.

This paper investigates the accuracy of forecasts from four DSGE models for inflation, output growth and the federal funds rate using a real-time dataset synchronized with the Fed’s Greenbook projections. Conditioning the model forecasts on the Greenbook nowcasts leads to forecasts that are as accurate as the Greenbook projections for output growth and the federal funds rate. Only for inflation the model forecasts are dominated by the Greenbook projections. A comparison with forecasts from Bayesian VARs shows that the economic structure of the DSGE models which is useful for the interpretation of forecasts does not lower the accuracy of forecasts. Combining forecasts of several DSGE models increases precision in comparison to individual model forecasts. Comparing density forecasts with the actual distribution of observations shows that DSGE models overestimate uncertainty around point forecasts.
Large companies are increasingly on trial. Over the last decade, many of the world’s biggest firms have been embroiled in legal disputes over corruption charges, financial fraud, environmental damage, taxation issues or sanction violations, ending in convictions or settlements of record-breaking fines, well above the billion-dollar mark. For critics of globalization, this turn towards corporate accountability is a welcome sea-change showing that multinational companies are no longer above the law. For legal experts, the trend is noteworthy because of the extraterritorial dimensions of law enforcement, as companies are increasingly held accountable for activities independent of their nationality or the place of the activities. Indeed, the global trend required understanding the evolution of corporate criminal law enforcement in the United States in particular, where authorities have skillfully expanded its effective jurisdiction beyond its territory. This paper traces the evolution of corporate prosecutions in the United States. Analyzing federal prosecution data, it then shows that foreign firms are more likely to pay a fine, which is on average 6,6 times larger.
One of the motivations for establishing a European banking union was the desire to break the ties with between national regulators and domestic financial institutions in order to prevent regulatory capture. However, supervisory authority over the financial sector at the national level can also have valuable public benefits. The aim of this policy letter is to detail these public benefits in order to counter discussions that focus only on conflicts of interest. It is informed by an analysis of how financial institutions interacted with policy-makers in the design of national bank rescue schemes in response to the banking crisis of 2008. Using this information, it discusses the possible benefits of close cooperation between financial institutions and regulators and analyzes these in the wake of a European banking union.
Both practitioners and academics agree about the importance of price and its direct influenceon consumers’ purchase decision as well as the company profit. In the reality, we rarely see a
single price for a given product. One visit in a store already shows that consumers face many various prices. This strategy of differential prices allows to increase profit but also improves consumers’ situation and increases welfare. A wide range of various price differentiation mechanisms exists on the market which makes price differentiation a very interesting phenomenon. Additionally, market developments constantly allow for new price differentiation applications. In this work, I research a fascinating topic of price differentiation, its various forms
and new application possibilities in changing market areas.
This paper studies the long-run effects of credit market disruptions on real firm outcomes and how these effects depend on nominal wage rigidities at the firm level. I trace out the long-run investment and growth trajectories of firms which are more adversely affected by a transitory shock to aggregate credit supply. Affected firms exhibit a temporary investment gap for two years following the shock, resulting in a persistent accumulated growth gap. I show that affected firms with a higher degree of wage rigidity exhibit a steeper drop in investment and grow more slowly than affected firms with more flexible wages.
