The election mechanism has difficulties in selecting the most able candidates and deselecting less able ones. In a simple model we show that the power of elections as a selection and incentive device can be improved by requiring higher vote thresholds than 50% for incumbents. A higher vote...

We suggest a development-compatible refunding system designed to mitigate climate change. Industrial countries pay an initial fee into a global fund. Each country chooses its national carbon tax. Part of the global fund is refunded to developing and industrial countries, in proportion to the...

We study the interplay between basic and applied research intensities in a simple model of creative destruction with research complementarities. Basic research intensity is chosen by the government and applied research intensity by the private sector. We find that the closer the country is to...

We examine the provision of public projects under tax and subsidy rules. We find that tax rules separated from project cum subsidy decisions exhibit several advantages when incentive problems of the agenda-setter are taken into account. In particular, tax rules may prevent the proposal of...

We examine debt-sensitive majority rules. According to such a rule, the higher a planned public debt, the higher the parliamentary majority required to approve it. In a two-period model we compare debt-sensitive majority rules with the simple majority rule when individuals differ regarding their...

We propose a formal concept of the power of voice in the context of a simple model where individuals form groups and trade in competitive markets. Individuals use outside options in two different ways. Actual outside options reflect the possibility to exit or to join other existing groups....

We study the allocation of commodities through a two-stage hierarchy of competitive markets. Groups or countries trade at global prices while individuals within a group trade at local prices. We identify the free trade and the autarky equilibrium as polar cases. We show that no other two-stage...

In this paper, we introduce a new requirement for bank capital: banking-on-the-average rules. Under these rules a bank’s required level of equity capital is monotonically increasing in the realized equity capital of its peers. In a simple model we illustrate the workings of...

We study household formation in a model where collective consumption decisions of a household depend on the strategic choices of its members. The surplus of households is determined by individual choices of levels of friendliness to each other. A strategic conflict arises from a coupling...

We examine how globalization affects firms’ incentives to provide general worker training. We consider a three-stage game. In stage 1, firms invest in productivity-enhancing training. In stage 2, they can make wage offers for each others’ workers. Finally, Cournot competition takes place....
