The Liikanen Group proposes contingent convertible (CoCo) bonds as a potential mechanism to enhance financial stability in the banking industry. Especially life insurance companies could serve as CoCo bond holders as they are already the largest purchasers of bank bonds in Europe. We develop a stylized model with a direct financial connection between banking and insurance and study the effects of various types of bonds such as non-convertible bonds, write-down bonds and CoCos on banks' and insurers' risk situations. In addition, we compare insurers' capital requirements under the proposed Solvency II standard model as well as under an internal model that ex-ante anticipates additional risks due to possible conversion of the CoCo bond into bank shares. In order to check the robustness of our findings, we consider different CoCo designs (write-down factor, trigger value, holding time of bank shares) and compare the resulting capital requirements with those for holding non-convertible bonds. We identify situations in which insurers benefit from buying CoCo bonds due to lower capital requirements and higher coupon rates. Furthermore, our results highlight how the Solvency II standard model can mislead insurers in their CoCo investment decision due to economically irrational incentives.
I assess how Basel III, Solvency II and the low interest rate environment will affect the financial connection between the bank and insurance sector by changing the funding patterns of banks as well as the investment strategies of life insurance companies. Especially for life insurance companies, the current low interest rate environment poses a key risk since declining returns on investments jeopardize the guaranteed return on life insurance contracts, a core component of traditional life insurance contracts in several European countries. I consider a contingent claim framework with a direct financial connection between banks and life insurers via bank bonds. The results indicate that life insurers' demand for bank bonds increases over the mid-term but ultimately declines in the long-run. Since life insurers are the largest purchasers of bank bonds in Europe, banks could lose one of their main funding sources. In addition, I show that shareholder value driven life insurers' appetite for risk increases when the gap between asset return and liability growth diminishes. To check the robustness of the findings, I calibrate a prolonged low interest rate scenario. The results show that the insurer's risk appetite is even higher when interest rates remain persistently low. A sensitivity analysis regarding industry-specific regulatory safety levels reveals that contagion between bank and life insurer is driven by the insurers' demand for bank bonds which itself depends on the regulatory safety level of banks.
The creation of the Banking Union is likely to come with substantial implications for the governance of Eurozone banks. The European Central Bank, in its capacity as supervisory authority for systemically important banks, as well as the Single Resolution Board, under the EU Regulations establishing the Single Supervisory Mechanism and the Single Resolution Mechanism, have been provided with a broad mandate and corresponding powers that allow for far-reaching interference with the relevant institutions’ organisational and business decisions. Starting with an overview of the relevant powers, the present paper explores how these could – and should – be exercised against the backdrop of the fundamental policy objectives of the Banking Union. The relevant aspects directly relate to a fundamental question associated with the reallocation of the supervisory landscape, namely: Will the centralisation of supervisory powers, over time, also lead to the streamlining of business models, corporate and group structures of banks across the Eurozone?
This paper examines the dynamic relationship between credit risk and liquidity in the sovereign bond market in the context of the European Central Bank (ECB) interventions. Using a comprehensive set of liquidity measures obtained from a detailed, quote-level dataset of the largest interdealer market for Italian government bonds, we show that changes in credit risk, as measured by the Italian sovereign credit default swap (CDS) spread, generally drive the liquidity of the market: a 10% change in the CDS spread leads a 11% change in the bid-ask spread. This relationship is stronger, and the transmission is faster, when the CDS spread is above the 500 basis point threshold, estimated endogenously, and can be ascribed to changes in margins and collateral, as well as clientele effects. Moreover, we show that the Long-Term Refinancing Operations (LTRO) intervention by the ECB weakened the sensitivity of the liquidity provision by the market makers to changes in the Italian government's credit risk. We also document the importance of market-wide and dealer-specific funding liquidity measures in determining the market liquidity for Italian government bonds.
The European Commission has published a Green Paper outlining possible measures to create a single market for capital in Europe. Our comments on the Commission’s capital markets union project use the functional finance approach as a starting point. Policy decisions, according to the functional finance perspective, should be essentially neutral (agnostic) in terms of institutions (level playing field). Our main angle, from which we assess proposals for the capital markets union agenda, are information asymmetries and the agency problems (screening, monitoring) which arise as a result. Within this perspective, we make a number of more specific proposals.
The paper traces the developments from the formation of the European Economic and Monetary Union to this date. It discusses the fact that the primary mandate of the European System of Central Banks (ESCB) is confined to safeguarding price stability and does not include general economic policy. Finally, the paper contributes to the discussion on whether the primary law of the European Union would support a eurozone exit. The Treaty of Maastricht imposed the strict obligation on the European Union (EU) to establish an economic and monetary union, now Article 3(4) TEU. This economic and monetary union is, however, not designed as a separate entity but as an integral part of the EU. The single currency was to become the currency of the EU and to be the legal tender in all Member States unless an exemption was explicitly granted in the primary law of the EU, as in the case of the UK and Denmark. The newly admitted Member States are obliged to introduce the euro as their currency as soon as they fulfil the admission criteria. Technically, this has been achieved by transferring the exclusive competence for the monetary policy of the Member States whose currency is the euro on the EU, Article 3(1)(c) TFEU and by bestowing the euro with the quality of legal tender, the only legal tender in the EU, Article 128(1) sentence 3 TFEU.
Die deutsche Steuerpolitik kombiniert hohe Steuersätze mit zahlreichen Ausnahmen. Das reißt Gerechtigkeitslücken, lenkt Investitionen in die falschen Zwecke und verkompliziert das Steuersystem mitunter bis zur Unkenntlichkeit. Bei der Erbschaftsteuer ist dies besonders augenfällig. Der Versuch mit minimalinvasiven Korrekturen Konsistenz in die Erbschaft- und Schenkungsteuer zu bringen ist fast zwangsläufig zum Scheitern verurteilt. Vieles spricht stattdessen für deutlich abgesenkte Steuersätze und eine gleichzeitige Abschaffung der Vergünstigungen für Betriebsvermögen.
This paper explores how banks adjust their risk-based capital ratios and asset allocations following an exogenous shock to their asset quality caused by Hurricane Katrina in 2005. We find that independent banks based in the disaster areas increase their risk-based capital ratios after the hurricane, while those part of a bank holding company do not. The effect on independent banks mainly comes from the subgroup of high-capitalized banks. These banks increase their holdings in government securities and reduce loans to non-financial firms. Hence, banks that become more stable achieve this at the cost of reduced lending.
A number of recent studies regress a "narratively" identified measure of a macroeconomic shock directly on an outcome variable. In this note, we argue that this approach can be viewed as the reduced-form regression of an instrumental variable approach in which the narrative time series is used as an instrument for an endogenous series of interest. This motivates evaluating the validity of narrative measures through the lens of a randomized experiment. We apply our framework to four recently constructed narrative measures of tax shocks by Romer and Romer (2010), Cloyne (2013), and Mertens and Ravn (2012). All of them turn out to be weak instruments for observable measures of taxes. After correcting for weak instruments, we find that using any of the considered narrative tax measures as an instrument for cyclically adjusted tax revenues yields tax multiplier estimates that are indistinguishable from zero. We conclude that the literature currently understates the uncertainty associated with quantifying the tax multiplier.
This paper studies a dynamic stochastic general equilibrium model involving climate change. Our model allows for damages on economic growth resulting from global warming. In the calibration, we capture effects from climate change and feedback effects on the temperature dynamics. We solve for the optimal state-dependent abatement policy. In our simulations, the costs of this policy measured in terms of lost GDP growth are moderate. On the other hand, postponing abatement action could reduce the probability that the climate can be stabilized. For instance, waiting for 10 years reduces this probability from 60% to 30%. Waiting for another 10 years leads to a probability that is less than 10%. Finally, doing nothing opens the risk that temperatures might explode and economic growth decreases significantly.
The banking system is highly interconnected and these connections can be conveniently represented as an interbank network. This survey presents a systematic overview of the recent advances in the theoretical literature on interbank networks. We assess our current understanding of the structure of interbank networks, of how network characteristics affect contagion in the banking system and of how banks form connections when faced with the possibility of contagion and systemic risk. In particular, we highlight how the theoretical literature on interbank networks offers a coherent way of studying interconnections, contagion processes and systemic risk, while emphasizing at the same time the challenges that must be addressed before general results on the link between the structure of the interbank network and financial stability can be established. The survey concludes with a discussion of the policy relevance of interbank network models with a special focus on macroprudential policies and monetary policy.
In this paper, we examine how the institutional design affects the outcome of bank bailout decisions. In the German savings bank sector, distress events can be resolved by local politicians or a state-level association. We show that decisions by local politicians with close links to the bank are distorted by personal considerations: While distress events per se are not related to the electoral cycle, the probability of local politicians injecting taxpayers’ money into a bank in distress is 30 percent lower in the year directly preceding an election. Using the electoral cycle as an instrument, we show that banks that are bailed out by local politicians experience less restructuring and perform considerably worse than banks that are supported by the savings bank association. Our findings illustrate that larger distance between banks and decision makers reduces distortions in the decision making process, which has implications for the design of bank regulation and supervision.
Against the background of the European debt crisis, the Research Center SAFE, in the fall of 2013, had issued a call for papers on the topic “Austerity and Economic Growth: Concepts for Europe”, with the objective of soliciting research proposals focusing on the nature of the relationship between austerity, debt sustainability and growth. Each of the five funded projects brought forth an academic paper and a shortened, non-technical policy brief. These policy papers are presented in the present collection of policy letters, edited by Alfons Weichenrieder.
The first paper by Alberto Alesina, Carlo Favero and Francesco Giavazzi looks into the question of how fiscal consolidations influence the real economy. Harris Dellas and Dirk Niepelt emphasize that fiscal austerity is a signal that investors use to tell apart governments with high and low default costs that accordingly will have a high or low probability of repayment.The paper by Benjamin Born, Gernot Müller and Johannes Pfeiffer,looks at the impact of austerity measures on government bond spreads. Oscar Jorda and Alan M. Taylor, in the fourth contribution, put into question whether the narrative records of fiscal consolidation plans are really exogenous. The final study by Enrique Mendoza, Linda Tesar and Jing Zhang suggests that fiscal consolidation should largely depend on expenditure cuts, rather than tax increases that may fail, when fiscal space is exhausted.
Spätestens seit die Europäische Zentralbank (EZB) ihr Ankaufprogramm für Wertpapiere bekannt gegeben hat, ist die Diskussion über die Wirksamkeit dieser Maßnahmen auch in Europa angekommen. Wegen der besonderen institutionellen Umstände des Euroraums – Kauf von Anleihen der einzelnen Nationalstaaten und des Verbots der monetären Finanzierung – reichen die möglichen Nebenwirkungen hierzulande über den rein geldpolitischen Horizont hinaus.
Regulatory failures, which came to the fore after the financial crisis of 2007-2009, lead to the question of why some activities by financial institutions were not regulated prior to the crisis of 2007, even though regulators knew about certain dangers to financial stability? The repo-market, although centrally involved in the last crisis, still awaits stringent regulation. At the same time, the regulatory cycle seems to come to an end, boding ill for future crises which will be amplified by this market. In this situation, NGOs are needed to make regulators act upon their knowledge and to tighten their regulations.
Greece: threatening recovery
(2015)
Despite the catastrophic phase between 2008 and the end of 2014, much of a previously unsustainable development has been corrected in Greece and there are clear signs that the deterioration came to a halt in 2014. But what is publicly known about the priorities of the newly elected Syriza government suggests that they may be going largely into the wrong direction.
This paper investigates whether a fiscal stimulus implies a different impact for flexible and rigid labour markets. The analysis is done for 11 advanced OECD economies. Using quarterly data from 1999 to 2013, I estimate a panel threshold structural VAR model in which regime switches are determined by OECD’s employment protection legislation index. My empirical results indicate significant differences between rigid and flexible labour markets regarding the impact of the fiscal stimulus on output and unemployment. While the impulse response of real GDP to a government spending shock is positive and more effective in flexible labour markets, it has less impact in the rigid ones. Moreover, it is found that a fiscal stimulus leads to higher overall unemployment in highly regulated countries.
Does exchange of information between tax authorities influence multinationals' use of tax havens?
(2015)
Since the mid-1990s, countries offering tax systems that facilitate international tax avoidance and evasion have been facing growing political pressure to comply with the internationally agreed standards of exchange of tax information. Using data of German investments in tax havens, we find evidence that the conclusion of a bilateral tax information exchange agreement (TIEA) is associated with fewer operations in tax havens and the number of German affiliates has on average decreased by 46% compared to a control group. This suggests that firms invest in tax havens not only for their low tax rates but also for the secrecy they offer.
Most recent regulations establish that resolution of global banking groups shall be done according to bail-in procedures and following a Single Point of Entry (SPE) as opposed to a Multiple Point of Entry (MPE) approach. The latter requires parent holding of global groups to put up front the equity capital needed to absorb losses possibly emerging in foreign subsidiaries-branches. No model rationalized so far such resolution regime. We build a model of optimal design of resolution regimes and compare three regimes: SPE with cooperative authorities, SPE with non-cooperative authorities and MPE (ring-fencing). We find that the costs for bondholders of bail-inable instruments is generally higher under noncooperative regimes and ring-fencing. We also find that in those cases banks have ex ante incentives to reduce their exposure in foreign assets. We also examine recent case studies that help us rationalize the model results.
We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a matching algorithm. We compare three alternative matching algorithms: maximum entropy, closest matching and random matching. Contagion occurs through liquidity hoarding, interbank interlinkages and fire sale externalities. The resulting network configurations exhibits a core-periphery structure, dis-assortative behavior and low clustering coefficient. We measure systemic importance by means of network centrality and input-output metrics and the contribution of systemic risk by means of Shapley values. Within this framework we analyze the effects of prudential policies on the stability/efficiency trade-off. Liquidity requirements unequivocally decrease systemic risk but at the cost of lower efficiency (measured by aggregate investment in non-liquid assets); equity requirements tend to reduce risk (hence increase stability) without reducing significantly overall investment.
Based on a sample of university students, we provide field and laboratory evidence that a small scale training intervention has a both statistically and economically significant effect on subjective and objective assessments of financial knowledge. We also show that for a large part of students whose self-assessed financial knowledge has improved we do not find an increase in their actual skills.
We set up and solve a rich life-cycle model of household decisions involving consumption of both perishable goods and housing services, stochastic and unspanned labor income, stochastic house prices, home renting and owning, stock investments, and portfolio constraints. The model features habit formation for housing consumption, which leads to optimal decisions closer in line with empirical observations. Our model can explain (i) that stock investments are low or zero for many young agents and then gradually increasing over life, (ii) that the housing expenditure share is age- and wealth-dependent, (iii) that perishable consumption is more sensitive to wealth and income shocks than housing consumption, and (iv) that non-housing consumption is hump-shaped over life.
This paper investigates whether exchanging the Social Security delayed retirement credit, currently paid as an increase in lifetime annuity benefits, for a lump sum would induce later claiming and additional work. We show that people would voluntarily claim about half a year later if the lump sum were paid for claiming any time after the Early Retirement Age, and about two-thirds of a year later if the lump sum were paid only for those claiming after their Full Retirement Age. Overall, people will work one-third to one-half of the additional months, compared to the status quo. Those who would currently claim at the youngest ages are likely to be most responsive to the offer of a lump sum benefit.
Traditional least squares estimates of the responsiveness of gasoline consumption to changes in gasoline prices are biased toward zero, given the endogeneity of gasoline prices. A seemingly natural solution to this problem is to instrument for gasoline prices using gasoline taxes, but this approach tends to yield implausibly large price elasticities. We demonstrate that anticipatory behavior provides an important explanation for this result. We provide evidence that gasoline buyers increase gasoline purchases before tax increases and delay gasoline purchases before tax decreases. This intertemporal substitution renders the tax instrument endogenous, invalidating conventional IV analysis. We show that including suitable leads and lags in the regression restores the validity of the IV estimator, resulting in much lower and more plausible elasticity estimates. Our analysis has implications more broadly for the IV analysis of markets in which buyers may store purchases for future consumption.
Klimaschutz- und Anpassungsmaßnahmen : Zielkonflikte und Synergien mit dem Biodiversitätsschutz
(2015)
Der Klimawandel ist eine der größten Herausforderungen der Gegenwart und seine Auswirkungen auf Natur, Gesellschaft und Wirtschaft werden vielfach untersucht. Minderungs- wie auch Anpassungsmaßnahmen sind somit ein wichtiges Handlungsfeld geworden. Während der Einfluss des Klimawandels auf die Biodiversität bereits seit Längerem Gegenstand wissenschaftlicher Untersuchungen ist, rücken nun auch mögliche Folgen von Klimaschutz- und Anpassungsmaßnahmen auf die biologische Vielfalt in den Fokus der Forschung: So ist eine generelle Treibhausgasreduktion zwar prinzipiell förderlich, jedoch kann die Umsetzung der hierfür notwendigen Maßnahmen zu Zielkonflikten mit dem Biodiversitätsschutz führen. Gleichwohl gibt es Herangehensweisen, die Synergien beider Bereiche erkennen lassen.
Das Papier bietet einen Überblick über Maßnahmen des Klimaschutzes und der Klimawandelanpassung in den Bereichen Wald- und Forstwirtschaft, Moore, Landwirtschaft, nachwachsende Rohstoffe, Fließgewässer, Küsten und Meere. Diese werden mit Blick auf ihre möglichen (sowohl förderlichen als auch abträglichen) Auswirkungen auf die Biodiversität vorgestellt. Mit dieser problemorientierten Diskursfeldanalyse soll ein Beitrag geleistet werden, potentielle Zielkonflikte von Klima- und Biodiversitätsschutz zu erkennen und Synergien zu fördern.
Some observers have conjectured that oil supply shocks in the United States and in other countries are behind the plunge in the price of oil since June 2014. Others have suggested that a major shock to oil price expectations occurred when in late November 2014 OPEC announced that it would maintain current production levels despite the steady increase in non-OPEC oil production. Both conjectures are perfectly reasonable ex ante, yet we provide quantitative evidence that neither explanation appears supported by the data. We show that more than half of the decline in the price of oil was predictable in real time as of June 2014 and therefore must have reflected the cumulative effects of earlier oil demand and supply shocks. Among the shocks that occurred after June 2014, the most influential shock resembles a negative shock to the demand for oil associated with a weakening economy in December 2014. In contrast, there is no evidence of any large positive oil supply shocks between June and December. We conclude that the difference in the evolution of the price of oil, which declined by 44% over this period, compared with other commodity prices, which on average only declined by about 5%-15%, reflects oil-market specific developments that took place prior to June 2014.
This paper is motivated by the fact that nearly half of U.S. college students drop out without earning a bachelor’s degree. Its objective is to quantify how much uncertainty college entrants face about their graduation outcomes. To do so, we develop a quantitative model of college choice. The innovation is to model in detail how students progress towards a college degree. The model is calibrated using transcript and financial data. We find that more than half of college entrants can predict whether they will graduate with at least 80% probability. As a result, stylized policies that insure students against the financial risks associated with uncertain graduation have little value for the majority of college entrants.
This paper studies a two-country production economy with complete and frictionless financial markets and international trade of final goods in which competition in R&D leads to endogenous new firm creation and economic growth. Current monopolists ("incumbents") and potential new firms ("entrants") compete in developing patents domestically. I find that this induces negative spillover in consumption, i.e. home country's consumption decreases in response to positive productivity shocks in the foreign country. Second, there is positive spillover in R&D expenditures, i.e. home country's R&D expenditures increase in response to positive foreign productivity shocks, which is consistent with empirical evidence on international technology diffusion. Furthermore, the stylized fact in international macroeconomics that the cross-country correlation of consumption growth is significantly lower than the one of output growth is explained by the model. Fourth, net exports are negatively correlated with output as in the data. Fifth, the model matches the high comovement of the risk-free rates and stock returns across countries. Finally, the model produces a positive value premium.
Projected demographic changes in industrialized and developing countries vary in extent and timing but will reduce the share of the population in working age everywhere. Conventional wisdom suggests that this will increase capital intensity with falling rates of return to capital and increasing wages. This decreases welfare for middle aged asset rich households. This paper takes the perspective of the three demographically oldest European nations — France, Germany and Italy — to address three important adjustment channels to dampen these detrimental effects of aging in these countries: investing abroad, endogenous human capital formation and increasing the retirement age. Our quantitative finding is that endogenous human capital formation in combination with an increase in the retirement age has strong implications for economic aggregates and welfare, in particular in the open economy. These adjustments reduce the maximum welfare losses of demographic change for households alive in 2010 by about 2.2 percentage points in terms of a consumption equivalent variation.
Although there is much interest in the future retail price of gasoline among consumers, industry analysts, and policymakers, it is widely believed that changes in the price of gasoline are essentially unforecastable given publicly available information. We explore a range of new forecasting approaches for the retail price of gasoline and compare their accuracy with the no-change forecast. Our key finding is that substantial reductions in the mean-squared prediction error (MSPE) of gasoline price forecasts are feasible in real time at horizons up to two years, as are substantial increases in directional accuracy. The most accurate individual model is a VAR(1) model for real retail gasoline and Brent crude oil prices. Even greater reductions in MSPEs are possible by constructing a pooled forecast that assigns equal weight to five of the most successful forecasting models. Pooled forecasts have lower MSPE than the EIA gasoline price forecasts and the gasoline price expectations in the Michigan Survey of Consumers. We also show that as much as 39% of the decline in gas prices between June and December 2014 was predictable.
In the aftermath of the global financial crisis, both resolution planning, i.e. contingency planning by both regulated institutions and public authorities in order to prepare their actions in financial crisis, and concepts for structural bank reform have been identified as possible solutions to ending “Too Big To Fail” and foster market discipline among bank owners, bank managers and investors in bank debt. Both concepts thus complement the global quest for reliable procedures and tools for bank resolution that would minimise systemic implications once large and complex financial institutions have reached the stage of insolvency. Given the complex task of orchestrating swift and effective resolution actions, especially with regard to cross-border banking groups and financial conglomerates, planning ahead in good times has since been widely recognised as crucial for enhancing resolvability. At least part of the impediments to resolution will be found in organisational, financial and legal complexity that has evolved in banks and groups over time. To remove these impediments, interference with existing corporate and group structures is all but inevitable. However, in both international standard setting and at the European Union level, issues related to resolution planning (within the context of bank resolution reform) and structural banking reforms to date have been discussed rather separately. This lack of consistency is questionable, given the obvious need to reconcile both approaches in order to facilitate effective implementation and enforcement especially with regard to large, complex banking groups. Based on an analysis both of the Bank Recovery and Resolution Directive and the SRM Regulation, this paper explores how these problems could be dealt with within the context of the European Banking Union.
