Die richtige wirtschaftspolitische Interpretation von rationalen Erwartungen – Erwiderung In einer Stellungnahme zu meinem Artikel kritisieren Wesche und Wierum die abgeleitete Beziehung zwischen Geldmengenwachstum und Inflation während eines Zeitraums sich beschleunigender Geldentwertung bei...

We examine democratic public-good provision with heterogeneous legislators. Decisions are taken by majority rule and an agenda-setter proposes a level of the public good, taxes, and subsidies. Members are heterogeneous with respect to their benefits from the public good. We find that, depending...

Starting from the Merton framework for firm defaults, we provide theanalytics and robustness of the relationship between defaultprobabilities and default correlations. We show that loans with higherdefault probabilities will not only have higher variances but also highercorrelations with other...

This paper discusses the relationship between premia for macroeconomic risk in banking, aggregate behavior, and banking crises. We consider a competitive banking system embedded in an overlapping generation model subject to repeated macroeconomic shocks. We highlight how risk premia decline when...

This paper studies the question to what extent premia for macroeconomic risks in banking are sufficient to avoid banking crises. We investigate a competitive banking system embedded in an overlapping generation model subject to repeated macroeconomic shocks. We show that even if banks fully...

We explore the impact of sophistication in risk management as required by Basel II on banking stability and market conditions. We compare a competitive banking system in which only average ratings are available with a competitive system in which banks are able to assess the default risk of...

We investigate the question of whether sophistication in risk management fosters banking stability. We compare a simple banking system in which an average rating is used with a sophisticated banking system in which banks are able to assess the default risk of entrepreneurs individually. Both...

This paper provides a macroeconomic perspective for government interventions in banking crises. We illustrate how vulnerabilities of the banking sector may build up over time and thus destabilize a banking system. A crisis occurs when a large number of banks fail to meet capital requirements or...

We examine whether and how democratic procedures can achieve socially desirable public good provision in the presence of profound uncertainty about the benefits of public goods, i.e., when citizens are able to identify the distribution of benefits only if they aggregate their private...

We compare integration of economic, matching and networking markets. There can be losers from integration in all three cases, but their relative numbers depend on the type of market. There can be many losers from integration of pure exchange economies. There are relatively few losers from...
