This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

This paper builds a macroeconomic model of equilibrium unemployment in which firms persistently face difficulties in selling their production and this affects their decisions to create jobs. Due to search-frictions on the product market, equilibrium unemployment is a U-shaped function of the...

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 propose a canonical model of optimal nonlinear redistributive taxation with matching unemployment. In our model, agents are endowed with different skill levels and labor markets are perfectly segmented by skill. The government only observes negotiated wages. More progressive taxation leads to...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

We develop and estimate a non-stationary job search model to evaluate a scheme that monitors job search effort and sanctions insured unemployed whose effort is deemed insufficient. The model reveals that such schemes provide incentives to the unemployed to front-load search effort prior to...

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...

In this paper we argue that, for a given overall level of labour income taxation, a more progressive tax schedule increases employment. From a theoretical point of view, higher progressivity increases overall employment through a wage moderating effect and also because employment of low-paid...

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...
