When politicians have lower discount factors than voters, democratic elections cannot sufficiently motivate politicians to undertake long-term socially beneficial projects. When politicians can offer incentive contracts which become effective upon reelection, the hierarchy of contracts and...

When politicians are provided with insufficient incentives by the democratic election mechanism, we show that social welfare can be improved by threshold contracts. A threshold incentive contract stipulates a performance level which a politican must reach in order to have the right to stand for...

We examine "Forward Guidance Contracts", which make central bankers' utility contingent on the precision of interest-rate forecasts for some time. Such Forward Guidance Contracts are a exible commitment device and can improve economic performance when the economy is stuck in a liquidity trap....

We present a model of elections in which interest group donations allow candidates to shift policy positions. We show that if donations were prohibited, then a unique equilibrium regarding the platform choices of candidates would exist. Our game with financing of political campaigns exhibits two...

We analyze whether different learning abilities of firms with respect to general equilibrium effects lead to different levels of unemployment. We consider a general equilibrium model where firms in one sector compete à la Cournot and a real wage rigidity leads to unemployment. If firms consider...

We consider competitive markets for multiple commodities with endogenous formation of one- or two-person households. Within each two-person household, externalities from the partnerś commodity consumption and unpriced actions are allowed. Each individual has two types of traits: observable...

We introduce democratic mechanisms where individual utilities are not observable by other people at the legislative stage. We show that the combination of three rules can yield e±cient provision of public projects: first, flexible and double majority rules where the size of the majority depends...

This paper analyses tax competition and tax coordination in a model where capital flows occur in the form of mergers and acquisitions, rather than greenfield investment. In this framework, we show that differences in residence based taxes do not necessarily distort international ownership...

In this paper we examine the potential of democratic constitutions for the provision of divisible public goods in a large economy. Our main insights are as follows: When aggregate shocks are absent, the combination of the following rules yields first-best allocations: a supermajority rule, equal...
