n a contribution prepared for the Athens Symposium on “Banking Union, Monetary Policy and Economic Growth”, Otmar Issing describes forward guidance by central banks as the culmination of the idea of guiding expectations by pure communication. In practice, he argues, forward guidance has proved a misguided idea. What is presented as state of the art monetary policy is an example of pretence of knowledge. Forward guidance tries to give the impression of a kind of rule-based monetary policy. De facto, however, it is an overambitious discretionary approach which, to be successful, would need much more (or rather better) information than is currently available. In Issing's view, communication must be clear and honest about the limits of monetary policy in a world of uncertainty.
This European Policy Analysis discusses the need to strengthen the institutions underpinning the euro and makes several policy recommendations. The Stability and Growth Pact must be reinforced, have greater automaticity and entail graduated sanctions. Fiscal surveillance must be improved through the establishment of a European Fiscal Stability Agency. Finally, the European Financial Stability Facility must be made permanent.

Unter der Überschrift "Ich kaufe griechische Staatsanleihen weil..." sollten Persönlichkeiten aus Politik, Wirtschaft und Kultur kurz begründen, warum sie griechische Staatsanleihen gekauft haben bzw. kaufen werden--idealerweise unter Nachweis ihres finanziellen Engagements. Zum jetzigen Zeitpunkt kaufe ich keine griechischen Staatsanleihen...
At the upcoming G20 meetings the issue what can be done to avoid a repetition of the current deep financial crisis will again be debated. Much attention and criticism will be directed to central banks. That is unavoidable: central banks must never again permit the development of financial imbalances that are large enough to lead to the collapse of major parts of the financial system when they unwind. In the future, policy makers must “lean against the wind” and tighten financial conditions if they perceive that imbalances are forming, even if there is little hard data to rely on. And they must be mindful that the costs of acting too late can dwarf those of acting too early.
In the event of a Greek exit from the Eurozone, the stronger members of the monetary union, especially Germany, face at least two risks: First, the debt of the Greek National Bank vis-à-vis the Eurosystem of central banks will most likely be lost. Secondly, the large flow of capital from Greece and other periphery countries to Germany will accelerate inflation.
We investigate the relationship between anchoring and the emergence of bubbles in experimental asset markets. We show that setting a visual anchor at the fundamental value (FV) in the first period only is sufficient to eliminate or to significantly reduce bubbles in laboratory asset markets. If no FV-anchor is set, bubble-crash patterns emerge. Our results indicate that bubbles in laboratory environments are primarily sparked in the first period. If prices are initiated around the FV, they stay close to the FV over the entire trading horizon. Our insights can be related to initial public offerings and the interaction between prices set on pre-opening markets and subsequent intra-day price dynamics.
he observed hump-shaped life-cycle pattern in individuals' consumption cannot be explained by the classical consumption-savings model. We explicitly solve a model with utility of both consumption and leisure and with educational decisions affecting future wages. We show optimal consumption is hump shaped and determine the peak age. The hump results from consumption and leisure being substitutes and from the implicit price of leisure being decreasing over time; more leisure means less education, which lowers future wages, and the present value of foregone wages decreases with age. Consumption is hump shaped whether the wage is hump shaped or increasing over life.
This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes towards risk and attitudes towards ambiguity are disentangled, providing pure measures of ambiguity aversion. Ambiguity aversion is captured in several ways, i.e. as a discount factor net of a risk premium, and as an estimated parameter in a generalized utility function. We find that ambiguity aversion varies across individuals, and with the level of ambiguity, being most prominent for intermediate levels. Around one third of subjects show no aversion, one third show maximum aversion, and one third show intermediate levels of ambiguity aversion, while there is almost no ambiguity seeking. While most theoretical work on ambiguity builds on maxmin expected utility, our results provide evidence that MEU does not adequately capture individual attitudes towards ambiguity for the majority of individuals. Instead, our results support models that allow for intermediate levels of ambiguity aversion. Moreover, we find risk aversion to be statistically unrelated to ambiguity aversion on average. Taken together, the results support the view that ambiguity is an important and distinct argument in decision making under uncertainty.
The idea of appointing a non-national as Central Bank Governor remains surprisingly controversial. Nevertheless, given the skills required by the Governor in order to manage what no doubt are increasingly complex institutions, considering non-nationals makes good sense for at least two reasons. First, increasing the pool of candidates to include those with broader skills and backgrounds makes it easier to find a suitable person for the job. Second, non-nationals are less likely to be beholden to domestic pressure groups and could help better insulate the central bank from political pressures.
The exceptional circumstances in which the ECB has been operating in the past years are testing not only the currency union itself, but also its institutional design. While the Governing Council of the ECB was designed to mainly set interest rates optimally for the union as a whole, the recent crisis has expanded the tools of the ECB to include unconventional monetary policy actions that potentially increase the risk exposure of its balance sheet. Since each country would contribute to the losses according to its capital key, a different voting mechanism that takes into account the single country’s contribution to the ECB’s capital could be advisable.

The European Commission's Green Paper "Audit Policy: Lessons from the Crisis" raises 38 questions regarding how the audit function could be enhanced in order to contribute to increased financial stability. The authors comment on these 38 questions, arguing that the general level of audit quality can be enhanced by extending the duties of care and by tightening the regulations on liability.
This article discusses the effects of the countercyclical premium discussed in insurance supervision in the context of Solvency II. While the basic principle of introducing countercyclical elements into Solvency II is endorsed, the authors argue for a system based on market scenarios which would enforce stricter capital requirements in boom times and less strict requirements in times of crisis.
The European Commission's Green Paper "The EU corporate governance framework" raises 25 questions in order to assess the effectiveness of the current corporate governance framework for European companies. The authors contribute to the EU's consultation, respond to the 25 questions and comment on the suggestions set out in the Green Paper.
We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/representative agent can be characterized by a specific semilinear partial differential equation. To date, the solution to this equation has mostly been approximated by Campbell-Shiller techniques, without addressing general issues of existence and uniqueness. We develop a novel approach that rigorously constructs the solution by a fixed point argument. We prove that under regularity conditions a solution exists and establish a fast and accurate numerical method to solve consumption-portfolio and asset pricing problems with recursive preferences and unspanned risk. Our setting is not restricted to affine asset price dynamics. Numerical examples illustrate our approach.
We study self- and cross-excitation of shocks in the Eurozone sovereign CDS market. We adopt a multivariate setting with credit default intensities driven by mutually exciting jump processes, to capture the salient features observed in the data, in particular, the clustering of high default probabilities both in time (over days) and in space (across countries). The feedback between jump events and the intensity of these jumps is the key element of the model. We derive closed-form formulae for CDS prices, and estimate the model by matching theoretical prices to their empirical counterparts. We find evidence of self-excitation and asymmetric cross-excitation. Using impulse-response analysis, we assess the impact of shocks and a potential policy intervention not just on a single country under scrutiny but also, through the effect on cross-excitation risk which generates systemic sovereign risk, on other interconnected countries.
Exit strategies
(2014)
We study alternative scenarios for exiting the post-crisis fiscal and monetary accommodation using a macromodel where banks choose their capital structure and are subject to runs. Under a Taylor rule, the post-crisis interest rate hits the zero lower bound (ZLB) and remains there for several years. In that condition, pre-announced and fast fiscal consolidations dominate - based on output and inflation performance and bank stability - alternative strategies incorporating various degrees of gradualism and surprise. We also examine an alternative monetary strategy in which the interest rate does not reach the ZLB; the benefits from fiscal consolidation persist, but are more nuanced.
We study the behavioral underpinnings of adopting cash versus electronic payments in retail transactions. A novel theoretical and experimental framework is developed to primarily assess the impact of sellers’ service fees and buyers’ rewards from using electronic payments. Buyers and sellers face a coordination problem, independently choosing a payment method before trading. In the experiment, sellers readily adopt electronic payments but buyers do not. Eliminating service fees or introducing rewards significantly boosts the adoption of electronic payments. Hence, buyers’ incentives play a pivotal role in the diffusion of electronic payments but monetary incentives cannot fully explain their adoption choices. Findings from this experiment complement empirical findings based on surveys and field data.
After initial temporary measures in support of Greece prooved insufficient to end the sovereign debt crisis, extensive countermeasures have ensued. The heads of state of the euro group have agreed to permanent support mechanims over the course of the past two years. In addition, the European Central Bank (ECB) has become involved in the assistance program. The article provides an overview of the various support mechanisms installed and cautions against the connected legal problems.

Contrary to widely held perceptions, workers in the southern European states that are most afflicted by the sovereign debt crisis work hard. However, labor productivity in these countries lags far behind the EU average. Structural reforms to boost productivity should be at the top of the reform agenda.
