It is often suggested that incentive schemes under moral hazard can be gamed by an agent with superior knowledge of the environment, and that deliberate lack of transparency about the incentive scheme can reduce gaming. We formally investigate these arguments. Ambiguous incentive schemes induce...

This paper studies the pruned state-space system for higher-order approximations to the solutions of DSGE models. For second- and third-order approximations, we derive the statistical properties of this system and provide closed-form expressions for first and second unconditional moments and...

This paper uses a monopolistic competitive framework with many sectors to study the impact of trade liberalization on local and global emissions. We focus on the interplay of the pollution haven effect and the home market effect and show how a large-market advantage can counterbalance a high...

This paper studies multi-agent optimal contracting with cost synergies. We model synergies as the extent to which effort by one agent reduces his colleague's marginal cost of effort. An agent's pay and effort depend on the synergies he exerts, the synergies his colleagues exert on him and,...

We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The benefit of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system without...

This paper revisits demographic dividend issues after almost two decades of debate. In 1998, David Bloom and Jeffrey Williamson used a convergence model to estimate the impact of demographic-transition-driven age structure effects and calculated what the literature has come to call the...

Exploring the period since the inception of the euro, we show that secondary-market yields on Italian public debt increase in anticipation of auctions of new issues and decrease after the auction, while no or a smaller such effect is present for German public debt. However, these yield movements...

During the Greek debt crisis after 2010, the German government insisted on harsh austerity measures. This led to a rapid cooling of relations between the Greek and German governments. We compile a new index of public acrimony between Germany and Greece based on newspaper reports and internet...

We use spatial regression discontinuity analysis to test whether the historical partition of Poland among three empires—Russia, Austria-Hungary, and Prussia—has a persistent effect on political outcomes in contemporary Poland and to examine the channels of this influence. We find that the...

We establish a theoretical as well as empirical framework to assess the role of resource endowments and their geographic location for inter-State conflict. The main predictions of the theory are that conflict tends to be more likely when at least one country has natural resources; when the...
