We introduce tax contracts and examine how they affect government formation and welfare of voters in a democracy with proportional elections. A tax contract specifies a range of tax rates a party is committed to if in government. We develop a new model of party competition in which parties...

We show that in democracies insufficient recognition of general equilibrium effects can lead to a crisis. We consider a two-sector economy in which a majoritarian political process determines governmental regulation in one sector: a minimum nominal wage. If voters recognize general equilibrium...

We examine whether it is sufficient for central banks to observe and forecast nominal variables only. Analyzing the interplay of wage-setting unions and a central bank we show that although central banks may not gain more information by directly acquiring data about indicators of real shocks in...

In this paper we examine how taxes, subsidies and the design of constitutional agendas should be regulated in order to allow for an efficient allocation of public goods and a limitation of tax distortions. We show that if public goods are socially desirable, the simple majority rule, combined...

This Paper compares the social efficiency of monetary targeting and inflation targeting when central banks may have private information on shocks to money demand and, because of verifiability problems, the transparency solution is not feasible. Under inflation targeting and monetary targeting,...

We develop a product market theory that explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each other’s trained employees and finally engage in imperfect product...

Agents from a homogeneous population organize themselves into productive partnerships and are confronted with a hold-up problem when making relation-specific investments in those partnerships. The problem is mitigated if agents can leave a partnership in which they have invested, bear the costs...

In this paper we examine the strategic implications of collective acquisition of information in a committee or in a legislature. We show that the prospect of acquiring information can harm a majority even if information is only available by the support of a majority. Moreover, the model provides...

We provide a simple justification as to why the core principal in liberal democracies the one-person-one-vote is desirable. We compare two possible constitutions. In a “fixed democracy”, each individual has one vote and the same opportunity to propose public projects. In a “flexible...
