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...

Do income taxes levied at a state or regional level affect the after-tax distribution of income? Or do workers merely move between regions, causing pre-tax wages to adjust? This question is relevant both in across states in the United States, and across countries within the European Union. Using...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

We derive conditions of individual preferences and technology that give rise to a negative correlation between income inequality and environmental protection. We present a class of models (which captures a static model as well as an overlapping-generations model) in which individuals differ in...

We study an economy where agents are heterogeneous in entrepreneurial ability, and may decide to become workers or entrepreneurs. The government is motivated by a production externality to impose regulations on entrepreneurship, and sets a level of red tape -administered by public officials-to...

This paper proposes a general framework for analysing commodity tax competition under destination and origin principles, based on three possible tax spillovers: the consumer price spillover, the producer price/terms of trade spillover, and rent spillovers. A model is presented which can be...

This paper shows that fiscal policy, when used for stabilization purposes, can have a positive effect on the economy's growth, on human capital accumulation, and on welfare, along the transition path. We introduce symmetric productivity shocks into a model in which productivity is augmented...

Both in theory and practice, capital controls and dual exchange rate systems can be part of a country's optimal tax policy. We first show how a dual exchange rate system can be interpreted as a tax (or subsidy) on international capital income. We show that a dual exchange rate system, with...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

Both the mining and the burning of coal is pollutive, so one might expect to observe taxes on coal production and consumption. Yet several countries in Western Europe subsidize coal production, and most East European countries subsidize coal consumption. The first part of this paper shows that...
