Recent work has analyzed the forecasting performance of standard dynamic stochastic general equilibrium (DSGE) models, but little attention has been given to DSGE models that incorporate nonlinearities in exogenous driving processes. Against that background, we explore whether incorporating stochastic volatility improves DSGE forecasts (point, interval, and density). We examine real-time forecast accuracy for key macroeconomic variables including output growth, inflation, and the policy rate. We find that incorporating stochastic volatility in DSGE models of macroeconomic fundamentals markedly improves their density forecasts, just as incorporating stochastic volatility in models of financial asset returns improves their density forecasts.
We propose a long-run risk model with stochastic volatility, a time-varying mean reversion level of volatility, and jumps in the state variables. The special feature of our model is that the jump intensity is not affine in the conditional variance but driven by a separate process. We show that this separation of jump risk from volatility risk is needed to match the empirically weak link between the level and the slope of the implied volatility smile for S&P 500 options.
The EU Collective Redress Recommendation has invited Member States to introduce collective redress mechanisms by 26 July 2015. The well-known reservations claim potentially abusive litigation and potential settlement of not well-founded claims resulting from controversial funding of cases by means of contingency fees and from ‘opt-out’ class action procedures. The paper posits that there may also be some fear that the European Commission may try to pursue the enforcement of its regulatory agenda in this way at the expense of individual claimants’ interests. Therefore a comparative analysis is carried out to see to what extent concerns about individual rights as opposed to regulatory goals are reflected in the different newly revised systems in place across Europe. As an iterim result the Dutch settlement procedure for mass damage claims, the English Group Litigation Order and the German test case procedure turn out to be relatively well-suited to deal with mass damage claims. At the same time, none of them can quite reach an optimal balance between individual rights and regulatory goals and therefore each of them is subject to criticism. That is why the further question is raised in how far these procedures could complement each other, thus contributing to the enforcement of individual rights without overregulating markets in Europe.
This paper sets the background for the Special Issue of the Journal of Empirical Finance on the European Sovereign Debt Crisis. It identifies the channel through which risks in the financial industry leaked into the public sector. It discusses the role of the bank rescues in igniting the sovereign debt crisis and reviews approaches to detect early warning signals to anticipate the buildup of crises. It concludes with a discussion of potential implications of sovereign distress for financial markets.
I analyze the real effects of the quality of the judicial enforcement by showing that an increase in the average duration of civil proceedings reduces firms' employment. I exploit a reorganization of court districts in Italy as an exogenous shock to court productivity and, using an instrumental variable approach, estimate an elasticity of employment to average trial length between -0.24 and -0.29. These results are very different from OLS estimates which do not control for endogeneity, and suggest that stronger law enforcement eases financing constraints. The effects are more pronounced in highly levered and more financially dependent firms, and appear to affect mainly firms in less financially developed areas. Revenues respond more slowly than employment to the reform, and wages fall as the judiciary improves. There is no evidence of effects on capital structure and profitability. These results offer a more complete picture of the interplay between legal institutions and real economic outcomes.
The Capital Markets Union-project of the European Commission aims for an increase of marketbased debt financing of small and medium-sized enterprises (SMEs), complementing bank lending. In this essay we argue that rather than focussing on pure non-bank lending, a reasonable mix of bankand market-based financing should be considered. Banks are said to have a comparative advantage in critical lending functions such as credit screening, debtor monitoring and debt renegotiation. All forms of lending require a persistent skin-in-the-game of critical players in order to be effective. The regulator should insist on full disclosure of skin-in-the-game, thereby improving capital allocation and reducing systemic risks.
Very few people doubt that it is a fundamental demand of justice that members of legal-political normative orders ought to have legal rights that define their basic standing as subjects of such an order. But when it comes to the concrete understanding of such rights, debates abound. What is the nature of these rights – are they an expression of the sovereign will of individuals, or are they based on important human interests? How should these rights be justified – do they have a particular moral ground, and if so, only one or many?
We introduce an innovative approach to measure bank integration, based on the corporate culture of multinational banking conglomerates. The new measure, the Power Index, assesses the prevalence of a language of power and authority in the financial reports of global banks. We employ a two-step approach: as a first step, we investigate whether parent-bank or parent-country characteristics are more important for bank integration. In a second step, we analyze whether bank integration affects the transmission of shocks across borders. We find that the level of integration of global banks is determined by parent-bank-specific factors, as well as by the social centralization in the parent’s country: ethnically diverse and linguistically homogenous countries nurture decentralized corporate structures. Political and economic factors, such as corruption, political rights and economic development also affect bank integration. Furthermore, we find that organizational integration affects the transmission of exogenous shocks from parent banks to their subsidiaries: the more centralized a global bank is, the lower the lending of its subsidiaries after a solvency shock. Wholesale shocks do not appear to be transmitted through this channel. Also, past experience with solvency shocks reduces the integration between parents and subsidiaries.
Public employees in many developing economies earn much higher wages than similar privatesector workers. These wage premia may reflect an efficient return to effort or unobserved skills, or an inefficient rent causing labor misallocation. To distinguish these explanations, we exploit the Kenyan government’s algorithm for hiring eighteen-thousand new teachers in 2010 in a regression discontinuity design. Fuzzy regression discontinuity estimates yield a civil-service wage premium of over 100 percent (not attributable to observed or unobserved skills), but no effect on motivation, suggesting rent-sharing as the most plausible explanation for the wage premium.
This paper presents new evidence on the expectation formation process of firms from a survey of the German manufacturing sector. It focuses on the expectation about their future business conditions, which enters the widely followed economic sentiment index and which is an important determinant of their employment and investment decisions. We find that firms extrapolate their experience too much and make predictable forecasting errors. Moreover, firms do not seem to anticipate the upcoming reversals of business cycle peaks and troughs which causes suboptimal adjustment of investment and employment and affects their inventories and profits. However, the impact on expectation errors decreases with the size and the age of the firm as firms learn to reduce their extrapolation bias over time.
Empirical evidence suggests that investments in research and development (R&D) by older and larger firms are more spread out internationally than R&D investments by younger and smaller firms. In this paper, I explore the quantitative implications of this type of heterogeneity by assuming that incumbents, i.e. current monopolists engaging in incremental innovation, have a higher degree of internationalization in their R&D technologies than entrants, i.e. new firms engaging in radical innovation, in a two-country endogenous growth general equilibrium model. In particular, this assumption allows the model to break the perfect correlation between incumbents’ and entrants’ innovation probabilities and to match the empirical counterpart exactly.
We shed new light on the macroeconomic effects of rising temperatures. In the data, a shock to global temperature dampens expenditures in research and development (R&D). We rationalize this empirical evidence within a stochastic endogenous growth model, featuring temperature risk and growth sustained through innovations. In line with the novel evidence in the data, temperature shocks undermine economic growth via a drop in R&D. Moreover, in our endogenous growth setting temperature risk generates non-negligible welfare costs (i.e., 11% of lifetime utility). An active government, which is committed to a zero fiscal deficit policy, can offset the welfare costs of global temperature risk by subsidizing the aggregate capital investment with one-fifth of total public spending.
Low probability events are overweighted in the pricing of out-of the-money index puts and single stock calls. We find that this behavioral bias is strongly time-varying, linked to equity market sentiment, and higher moments of the risk-neutral density. An implied volatility (IV) sentiment measure that is jointly derived from index and single stock options explains investors' overweight of tail events the best. Our findings also suggest that IV-sentiment predicts equity markets reversals better than overweight of small probabilities itself. When employed in a trading strategy, IV-sentiment delivers economically significant results, which are more consistent than the ones produced by the market sentiment factor. The joint use of information from the single stock and index option markets seems to explain the forecasting power of IV-sentiment. Out-of-sample tests on reversal prediction show that our IV-sentiment measure adds value over and above traditional factors in the equity risk premium literature, especially as an equity-buying signal. This reversals prediction seems to improve time-series and cross-sectional momentum strategies.
We investigate how solvency and wholesale funding shocks to 84 OECD parent banks affect the lending of 375 foreign subsidiaries. We find that parent solvency shocks are more important than wholesale funding shocks for subsidiary lending. Furthermore, we find that parent undercapitalization does not affect the transmission of shocks, while wholesale shocks transmit to foreign subsidiaries of parents that rely primarily on wholesale funding. We also find that transmission is affected by the strategic role of the subsidiary for the parent and follows a locational, rather than an organizational pecking order. Surprisingly, liquidity regulation exacerbates the transmission of adverse wholesale shocks. We further document that parent banks tend to use their own capital and liquidity buffers first, before transmitting. Finally, we show that solvency shocks have higher impact on large subsidiary banks with low growth opportunities in mature markets.
This paper applies the theory of structured finance to the regulation of asset backed securities. We find the current regulation in Europe (Article 405 of the CRR) and the US (Section D of Dodd-Frank Act) to be severely flawed with respect to its key intention: the imposition of a strict loss retention requirement. While nominal retention is always 5%, the true level of loss retention varies across available retention options between zero loss retention and full loss retention at the extreme ends. Based on a standard model of structured finance transactions, we propose a new risk retention metric RM measuring the level of an issuer’s skin-in-the-game. The new metric could help to achieve a better implementation of CRR/CRD-IV and DFA, by making disclosure of the RM-number compulsory for all ABS transactions. There are also implications for the operation of rating agencies. On a general level, the RM metric will be instrumental in achieving simplicity and transparency in securitizations (STS).
This paper analyzes the bail-in tool under the Bank Recovery and Resolution Directive (BRRD) and predicts that it will not reach its policy objective. To make this argument, this paper first describes the policy rationale that calls for mandatory private sector involvement (PSI). From this analysis, the key features for an effective bail-in tool can be derived.
These insights serve as the background to make the case that the European resolution framework is likely ineffective in establishing adequate market discipline through risk-reflecting prices for bank capital. The main reason for this lies in the avoidable embeddedness of the BRRD’s bail-in tool in the much broader resolution process, which entails ample discretion of the authorities also in forcing private sector involvement. Moreover, the idea that nearly all positions on the liability side of a bank’s balance sheet should be subjected to bail-in is misguided. Instead, a concentration of PSI in instruments that fall under the minimum requirements for own funds and eligible liabilities (MREL) is preferable.
Finally, this paper synthesized the prior analysis by putting forward an alternative regulatory approach that seeks to disentangle private sector involvement as a precondition for effective bank-resolution as much as possible form the resolution process as such.
Die Geschichte des Urheberrechts ist die Geschichte seiner Expansion. In diesem Beitrag wird die Expansionsgeschichte des Urheberrechts, in der das Urheberrechtsgesetz 1965 letztlich nur eine, wenn auch wichtige Episode darstellt, in Anlehnung an Thesen des 1944 erschienenen, wirtschaftssoziologischen Klassikers „The Great Transformation. Politische und ökonomische Ursprünge von Gesellschaften und Wirtschaftssystemen“ von Karl Polanyi gedeutet. Im Zentrum steht dabei der Gedanke, dass in einer Informationsgesellschaft, deren Wirtschaft auf Märkten und Wettbewerb beruht, alle neuen Technologien und hiermit verknüpften immateriellen Leistungsergebnisse über Ausschließlichkeitsrechte zugeordnet werden müssen, damit gewährleistet ist, dass alle relevanten In- und Outputfaktoren handelbar sind, so dass ihre jeweiligen Erzeuger marktbasierte Einkünfte erzielen können. Der Aufsatz erläutert, dass sich diese Kommodifizierungslogik in der jüngeren deutschen Urheberrechtsgeschichte nachweisen lässt. Auf die soziologische und rechtliche Relevanz der entgegengesetzten Zugangsnorm wird im Schlussteil hingewiesen.
