We present a general equilibrium analysis of biofuel subsidies in an open-economy context. In the small-country case, when a Pigouvian tax on conventional fuels such as crude is in place, the optimal biofuel subsidy is zero. When the tax on crude is not available as a policy option, however, a...

This paper presents a model of legal migration from one source country to two host countries, both of which can control their levels of immigration. Because of complementarities between capital and labor, the return on capital is positively related to the level of immigration. Consequently, when...

We discuss a principal-agent model in which the principal has the opportunity to include a non-compete agreement in the employment contract. We show that not imposing such an agreement can be beneficial for the principal as the possibility to leave the firm generates implicit incentives for the...

We examine ways of funding higher education, comparing upfront tuition fees with graduate taxes. The tax dominates, as volatility in future income is transferred from risk-averse students to the risk-neutral state. However, a double moral hazard problem arises when students' efforts to raise...

We examine the interaction between foreign aid and binding borrowing constraint for a recipient country. We also analyze how these two instruments affect economic growth via non-linear relationships. First of all, we develop a two-country, two-period trade-theoretic model to develop testable...

Reflecting recent enforcement policy activism of US states, this paper examines federal-state overlap of illegal immigration policy in a spatial context. Keeping the US-Mexico context in mind, we assume that labor from a source nation enters a host nation through bordering states. Once in the...

It is often claimed that supervisors do not differentiate enough between high and low performing employees when evaluating performance. The purpose of this paper is to study the incentive effects of this behavior empirically. We first show in a simple model that the perceived degree of past...

We investigate the effects of inequality in wealth on the incentives to contribute to a public good when agents are inequity averse and may differ in ability. We show that equality may lead to a reduction of public good provision below levels generated by purely selfish agents. But introducing...

This paper investigates the effects of managerial incentives on favoritism in promotion decisions. First, we theoretically show that favoritism leads to a lower quality of promotion decisions and in turn lower efforts. But the effect can be mitigated by pay-for-performance incentives for...
