How will international integration affect welfare policies? This paper considers the possibilities of financing public sector activities (public consumption and social security expenses) by general (wage) taxation in an economy which becomes more integrated in international product markets. Even...

Most public finance theorizing treats its material of public finance as reflecting some ruler's optimizing choices. Within democratic regimes this ruler is typically a median vote. While this approach has tractability on its side, it achieves that tractability by presenting caricatures of...

A key property of the Aiyagari-type heterogeneous-agent models is that the equilibrium interest rate of public debt lies below the time discount rate. This fundamental property, however, implies that the Ramsey planner's fiscal policy may be time-inconsistent because the forward-looking planner...

How are the optimal tax and debt policies affected if the government has the option to default on its debt? We address this question from a normative perspective in an economy with noncontingent government debt, domestic default and labor taxes. On one hand, default prevents the government from...

We evaluate the effectiveness of non optimal and temporally inconsistent incentive policies for regulating the exploitation of a renewable common-pool resource. The corresponding game is an N-person discrete-time deterministic dynamic game of T periods fixed duration. Three policy instruments...

In the standard multi-period model, the general consumption tax and the wage tax are equivalent. When a capital market is incomplete, such that the rate of return from capital is idiosyncratic, the consumption tax, in contrast to the wage tax, can play a role in risk-sharing. However,...

The creation of tax-free health savings accounts presents a new opportunity to reduce the distortions created by federal tax preferences for health-related expenditures, and ultimately help eliminate those distortions. This paper proposes changes to current law that would allow most workers to...

How does uncertainty affect the process of policy reform? Our investigation identifies two types of uncertainties, one at the electoral level and another at the implementation level. When voters abstain from the electoral process, electoral uncertainty emerges. Implementation uncertainty arises...

Substantial variations in the cost of living among regions in the United States are a major impediment to achieving a fair and equitable income tax system. Geographic cost of living differences arise because of disparities in the consumption power of income in different regions. Although the...
