With many countries considering the adoption of a system of earned income tax credits, it is useful to analyze how different types of credits affect labor supply and earnings. This paper focuses on a 1999 reform to the UK tax credit system, which increased the value of the credit and reduced the...

We analyze the role of optimal income taxation across different local labor markets. Should labor in large cities be taxed differently than in small cities? We find that a planner who needs to raise revenue and is constrained by free mobility of labor across cities does not choose equal taxes...

We analyze the effect of a large group on an impure public goods model with lotteries. We show that as populations get large, and with selfish preferences, the level of contributions converges to the one given by voluntary contributions. With altruistic preferences (of the warm glow type), the...

There is often a gap between the prescriptions of an "optimal" tax system and actual tax systems, some of which can be neither efficient economically nor efficient at redistributing income. With a focus on personal income taxes, this paper reviews the political economics literature on tax...

This paper analyzes the problem of optimal taxation of top labour incomes. We develop a model where top incomes respond to marginal tax rates through three channels: (1) the standard supply-side channel through reduced economic activity, (2) the tax avoidance channel, (3) the compensation...

Many countries have failed to use natural resource wealth to promote growth and development. They have been damaged by volatility of revenues, have failed to save a sufficiently high proportion of their resource revenues and failed to make high return investments to support diversification of...

Given its signiÖcance in practice, piecewise linear taxation has received relatively little attention in the literature. This paper o§ers a simple and transparent analysis of its main characteristics. We fully characterize optimal tax parameters for the cases in which budget sets are convex...

We follow the approach of Grochulski (2007), who determines the optimal income tax schedule when individuals have the possibility of avoiding paying taxes. We however modify his setup by considering a convex concealment cost function. This assumption violates the subadditivity property used in...

We explore the consequence for taxation and regulation of bonus pay when investors are protected by taxpayers from downside risk. The paper develops a model where workers in financial sector firms make decisions about effort and risk-taking which are influenced by the structure of bonus pay....

What structure of income taxation maximizes the social benefits of redistribution while minimizing the social harm associated with distorting the allocation of labor input? Many authors have advocated scrapping the current tax system, which redistributes primarily via marginal tax rates that...
