We study how natural-resource rents affect the risk of internal conflict within countries and how the federal structure of countries influences this relationship. Natural-resource abundance may induce excessive rent-seeking and thus increase the risk of internal conflict. Fiscal and political...

We analyze the effects of wage floors on optimal job design in a moral-hazard model with asymmetric tasks and imperfect aggregate performance measurement. Due to cost advantages of specialization, assigning the tasks to different agents is efficient. A sufficiently high wage floor, however,...

We study optimal capital taxation in a dynamic Mirrleesian model with time-nonseparable preferences. The model covers the widely used cases of habit formation and durable consumption. Time-nonseparable preferences change labor supply incentives across time and thereby generate novel motives to...

In the recent financial crisis, risk management tools have been proven inadequate. Model risk, a key component of bank risk, has shown its negative impact. It seems that risk models did not cover the included risks comprehensively and were not kept up-to-date by banks, and also rating agencies....

In Germany, it has become conventional wisdom that the economic uncertainty associated fixed-term employment contracts prevents young couples from realizing their desire to have children. From a research perspective, it is however far from clear whether fixed-term contracts are the obstacle to...

A frequent feature of information structures is that they generate signals which are not mutually independent, but rather rely on a common set of underlying information. Using a simple experimental design, we show that in such contexts many people neglect correlations in the updating process,...

Applying the Monti-Klein framework, we examine the optimal financing strategy of a fi rm that requires funding for individual projects at an imperfect credit market. In particular, we study under which circumstances the firm should raise debt for projects separately (decentralized funding) or...

In the academic literature, the economic interpretation of stock market volatility is inherently ambivalent, being considered an indicator of either information flow or uncertainty. We show in a stylized model economy that both views suggest volatility-dependent cross-market spillovers. If...

This paper shows how conflicting normative views of fair contribution rules can be used to design sequential contribution mechanisms to foster human cooperation in heterogeneous populations. Our model predicts that a sequential mechanism which solicits contributions first from wealthy actors...

This paper uses several macroeconomic and financial indicators within a Markov Switching (MS) framework to predict the turning points of the business cycle. The presented model is applied to monthly German real-time data covering the recession and the recovery after the financial crisis. We show...
