Suppose an altruistic person - A - is willing to transfer resources to a second person - B - if B comes upon hard times. If B anticipates that A will act in this manner, B will save too little from both agents’ point of view. This is the Samaritan’s dilemma. The logic of the dilemma has been...

This Paper models aid agencies as financial intermediaries that do not make a financial return to depositors, since the depositors' concern is to transfer resources to investor-beneficiaries. This leads to a significant problem of verification of the agencies' activities. One solution to this...

We analyze optimal dynamic taxation when labor supply is indivisible, as in Hansen (1985) and Rogerson (1988). Markets are complete, and an employment lottery determines who works. The consumer can buy insurance to diversify this extrinsic income uncertainty. The optimal wage tax is zero in both...

We study the impact of tax competition on equilibrium taxes and welfare, focusing on the jurisdictional fragmentation of federations. In a representative-agent model of fiscal federalism, fragmentation among jurisdictions with benevolent tax-setting authorities unambiguously reduces welfare. If,...

How should aggregate public expenditures be traded off against their financing costs? We incorporate public expenditures into a standard neoclassical growth setup with model policy choice as made by a government choosing tax rates and spending so that the resulting competitive equilibrium...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

We analyse the question of optimal taxation in a dual economy, when the policy-maker is concerned about the distribution of labour income. Income inequality is caused by the presence of sunk capital investments, which creates a ‘good jobs’ sector due to the capture of quasi-rents by trade...

In a dynamic optimizing model with costly tax collection, a tax cut by one nation creates positive externalities for the rest of the world if initial public debt stocks are positive. By reducing tax collection costs, current tax cuts boost the resources available for current private consumption,...

We study a setting with search frictions in the marriage market and with incomplete contracting inside the family. Everyone prefers a partner that has a high income and is a perfect emotional match, but compromises must often be struck. A high-income earner may abstain from marrying a low-income...
