We consider tax competition in a world with tax bases exhibiting different degrees of mobility, modeled as mobile and immobile capital. An agreement among countries not to give preferential treatment to mobile capital results in an equilibrium where mobile capital is nevertheless taxed...

Law enforcement is decentralized. It is so despite documented interjurisdictional externalities which would justify its centralization. To explain this fact, we construct a political economy model of law enforcement. Under decentralization, law enforcement in each region is in accord with the...

We develop a model of a competitive rental housing market with endogenous default due to income uncertainty. There is a large number of identical, potential suppliers who each face a fixed cost of entering the rental housing market. Those suppliers who choose to enter decide how many rental...

We study whether social welfare recipients may end up paying more for their grocery if social welfare payments are more concentrated over time. We first present a theoretical model showing that lower incomes in general and a lower lower bound of the income distribution lead to less mobility for...

This paper studies interjurisdictional competition in the fight against crime and its impact on occupational choice and the allocation of capital. In a world where capital is mobile, jurisdictions are inhabited by individuals who choose to become workers or criminals. Because the return of the...

We consider the implications of ethical behaviour on the effect of a redistributive tax-transfer system. In choosing their labour supplies, individuals take into account whether their tax liabilities correspond to what they view as ethically acceptable. If tax liabilities are viewed as ethically...

A two-region economy consists of a given but different number of immobile workers in each region, and a given number of mobile firms. Firms create jobs where they locate, but there is frictional unemployment. Two sorts of agglomeration effects arise: those from economies of scale in matching,...

We consider a world in which the mode of food production, foraging or agriculture, is endogenous, and in which technology grows exogenously. Within a model of coalition formation, we allow individuals to rationally form cooperative communities (bands) of foragers or farmers. At the lowest levels...
