We analyze the topical question of how the compensation of elected politicians affects the set of citizens choosing to run. To this end, we develop a sparse and tractable citizen-candidate model of representative democracy with ability differences, informative campaigning and political parties....

This paper studies whether and how banks’ technological innovations affect the bank lending channel of monetary policy transmission. We first provide a theoretical model in which banks' technological innovation relaxes firms’ earning-based borrowing constraints and thereby enlarges the...

We argue that a patent system makes collusion among innovators more difficult. Our simple argument is based on two properties of the patent system. First, a patent not only protects against infringement but also against retaliation by former collusion members. Second, a deviator has an equal...

We study a financial market adverse selection model where all agents are endowed with initial wealth and choose to invest as entrepreneurs or financiers, or not to invest. We show that often a lack of outside finance leads to the emergence of financial markets where availability of outside...

We study the effects of investor protection on the availability of external finance, entrepreneurship, and creation of new firms in an equilibrium search model of private capital markets. In addition to search frictions, we examine contract frictions, specifically interim and ex post moral...

We develop a new method to estimate the returns to R&D, their distribution, and their determinants. We model a continuous optimal treatment with outcome heterogeneity, where the treatment outcome depends on the applicant’s investment. The model takes into account application costs, and...

In earlier literature, the suggested Pareto improvements in pay-as-you- go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

Both current and especially new member states of the European Union face incentives to distort the provision of public education away from internationally applicable education towards country-specific skills. This would mean educating too few engineers, economists and doctors, and too many...

I analyze simultaneous voting on the wage tax rate and investment in public education using a model with three overlapping generations and ability differences inside each cohort. Wage tax revenue finances public education and social security benefits. I derive the results both for a...

The mobility of labor reduces national incentives to invest in internationally applicable education. Such effects may be especially severe for the prospective new member states of the European Union. The European Union could overcome this by allowing countries to institute graduate taxes or...
