We examine how democracies choose their amount of checks and balances (C&B). For this purpose, we consider a simple model of political competition with costly policy reforms. The cost of a marginal reform is determined endogenously at the constitutional phase-i.e. before policies are...

We integrate banks and the coexistence of bank and bond financing into an otherwise standard New Keynesian framework. There are two policy-makers: a central banker, who can decide on short-term nominal interest rates, and a macroprudential policy-maker, who can vary aggregate capital...

What is the economic rationale for investing in science? Based on an open economy model of creative destruction, we characterize four key factors of optimal investment in basic research: the stage of economic development, the strength of the manufacturing base, the degree of openness, and the...

Innovation clusters combining public and private effort to develop breakthrough technologies promise greater technological advances to slow down climate change. We use a multi-country model with emissions permit trade to examine how international climate policy can incentivize countries to...

We study how to efficiently motivate policy-makers to solve political multitask problems. Political multi-task problems typically have outcomes that are difficult to measure. Moreover, there are conflicts among citizens about optimal policies and the agents have the power to tax the citizens to...

We study the political economy of bank capital regulation from a positive and normative perspective. In a general equilibrium setting, capital requirements and lobbying contributions are determined as the outcome of bargaining between banks and politicians. We show that bankers and politicians...

As the performance of long-term projects is not observable in the short run politicians may pander to public opinion. To solve this problem, we propose a triple mechanism involving political information markets, reelection threshold contracts, and democratic elections. An information market is...

This paper studies the formation of human capital and its transmission across generations when premature adult mortality is a salient feature of the demographic landscape, either permanently or in the form of a long-period wave that follows the outbreak of an epidemic. We establish several...

We propose a global refunding scheme as a new international approach to addressing climate change. A global refunding system allows each country to set its carbon emission tax, while aggregate tax revenues are partially refunded to member countries in proportion to the relative emissions...

We examine the legislative game with open rules proposed by Baron and Ferejohn (1989). We first show that the three-group equilibrium suggested by Baron and Ferejohn does not always obtain. Second, we characterize the set of stationary equilibria for simple and super majority rules. Such...
