Income cap or threshold systems rely on incentives that encourage physicians to limit medical expenditures, but little is known about how physicians respond to these incentives. Conceptually, the threshold system is to physicians what an income tax system is to taxpayers. We exploit this...

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 examines the role of public education in the context of parental migration, and it studies the effects of an expansive income tax policy that is adopted to increase public education expenditure per pupil. It is shown that such a policy may exacerbate income inequality in the long run...

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...

This paper shows that outsourcing of parts of workforce in unionized firms leads to wage moderation both in the case of strategic and flexible outsourcing and as long as the share of the outsourced workforce is not too large, this wage-moderation effect on domestic employment outweighs the...

This paper studies in the presence of flexible outsourcing the effects of outsourcing costs, productivity of outsourcing, wage tax and tax exemption in an imperfectly competitive labour markets when labour unions and firms negotiate wages and the impacts of labour tax progression on domestic...

We evaluate the effects of international outsourcing and labor taxation on wage formation and equilibrium unemployment in dual labor markets. Outsourcing promotes wage dispersion between the high-skilled and low-skilled workers. Higher domestic low-skilled wage tax, higher payroll tax and lower...

Gender Based Taxation (GBT) satisfies Ramsey's optimal criterion by taxing less the more elastic labor supply of (married) women. This holds when different elasticities between men and women are taken as exogenous and primitive. But in this paper we also explore differences in gender...

Using micro-level data, we examine the effects of Russia's 2001 flat rate income tax reform on consumption, income, and tax evasion. We use the gap between household expenditures and reported earnings as a proxy for tax evasion with data from a household panel for 1998-2004. Utilizing...

We evaluate reforms to the U.S. tax system in a dynamic setup with heterogeneous married and single households, and with an operative extensive margin in labor supply. We restrict our model with observations on gender and skill premia, labor force participation of married females across skill...
