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...

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...

We consider a two-period model. In the first period, individuals consume two goods: one is sinful and the other is not. The sin good brings pleasure but has a detrimental effect on second period health and individuals tend to underestimate this effect. In the second period, individuals can...

This Paper explores the optimal role of the tax system in alleviating labour-market imperfections and raising revenue. For this purpose, the standard search model of the labour market is extended by introducing scarce entrepreneurial talent and arbitrage between the supply and demand. We study...

This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to 'unretire', i.e., unexpectedly return to work. It also shows that when myopia about habit formation leads to...

This Paper discusses the role of public policy towards the venture capital industry. The model emphasises four margins: supply of entrepreneurs due to career choice, entry of venture capital funds and search for investment opportunities, simultaneous entrepreneurial effort and managerial advice...
