International Cartel Enforcement: Lessons from the 1990s

The enforcement record of the 1990s has demonstrated that international private cartels are neither relics of the past nor do they always fall quickly under the weight of their own incentive problems. Of a sample of forty cartels prosecuted by the United States and European Inion in the 1990s, twenty-four cartels lasted at least four years. And for the twenty of the cartels in this...

Liliput oder Leviathan? Der Staat in der Globalisierten Wirtschaft

Globalization is often seen to result in a smaller (Liliput) or larger (Leviathan) state. But future public activity will be more flexible. Persons have multiple identities. They can be citizens of sub- and supra-national jurisdictions, semi- and non-governmental organizations and private units, even profit-oriented firms. Such attachment may be temporary, multiple or partial. To...

This paper studies a monetary economy with heterogenous agents in which trade takes place in a centralized market. Each agent is a potential producer and consumer of a service (or perishable good) but has stochastic preferences that determines his taste for the good in each period in time. Money serves as a medium of exchange as well as a store of value. We prove existence of...

From Rags to Riches: On Constant Proportions Investment

This paper studies the performance of self-financing constant proportions trading strategies, i.e. dynamic asset allocation strategies that keep a fixed constant proportion of wealth invested in each asset in all periods in time. We prove that any self-financing constant proportions strategy yields a strictly positive exponential rate of growth of investor's wealth in a...

Beitraege, die Grenzen fuer das Wachstum von Finanzintermediaeren aufzeigen, sind indessen selten. Das vorliegende Papier baut auf einem Modell von...

Cycles of aggregate behavior in theory and experiment

We test in the laboratory the potential of evolutionary dynamics as predictor of actual behavior. To this end, we propose an asymmetric game (which we interpret as a borrower–lender relation), we study its evolutionary dynamics in a random matching setup, and we test its predictions. The theoretical model provides conditions for changes in qualitative aggregate behavior in response...

Homo Oeconomicus Versus Homo Reciprocans: Ansätze für ein Neues Wirtschaftspolitisches Leitbild?

Politik und öffentliches Bewusstsein werden zunehmend durch ökonomische Theorien und Handlungsvorschläge mitbestimmt. Kaum ein anderes erkenntnis- und handlungsleitendes Modell hat daher einen vergleichbaren Einfluss wie das Konzept des Homo Oeconomicus. Durch die Entwicklung experimenteller Methoden ist es möglich, die Annahmen dieses Konzepts unter kontrollierten Laborbedingungen...

The Lucas Critique in Practice: An Empirical Investigation of the Impact of European Monetary ...

An empirical investigation of the term structure (the relation of the long interest rate to the short interest rate) showed structural change as the deadline for the euro became closer. Our empirical analysis of the term structures (yield curves) in 12 OECD countries uncovers that econometrically estimated behavioural equations for most EMU countries were stable even in the light of...

Market Selection of Financial Trading Strategies: Global Stability

In this paper we analyze the long-run dynamics of the market selec-tion process among simple trading strategies in an incomplete asset market with endogenous prices. We identify a unique surviving finan-cial trading strategy. Investors following this strategy asymptotically gather total market wealth. This result generalizes findings by Blume and Easley (1992) to any complete or...

Monetary Policy and the Fisher Effect

Historical estimates of the informational content in the yield curve may not be relevant after a change in monetary policy. This study uses a small dynamic rational expectations model with staggered price setting to study how monetary policy affects the relation between nominal interest rates, inflation expectations, and real interest rates. The benchmark parameters, including the...

Fossile Energiepolitik jenseits von Kyoto

Given the USA`s refusal to ratify there is little hope for the Kyoto agreement on curbing CO2 emissions. This paper thus pledges for a national energy policy beyond Kyoto based on local external effects stemming from the combustion of fossil fuels. Due to varying external effects a national policy will differentiate energy taxes between fuels. Using Swiss estimates of external...

Was erklärt die steigenden Managerlöhne? Ein Diskussionsbeitrag

"Die Entlohnung von Topmanagern ist in den westlichen Industrieländern über die letzten Jahre markant angestiegen. Wir stellen verschiedene Ansätze dar, welche diese Entwicklung zu erklären versuchen, und prüfen sie auf ihren Erklärungsgehalt: (1) Die Entwicklung ist das Ergebnis eines gut funktionierenden Marktprozesses; sie beruht auf strukturellen Veränderungen auf der...
