The Atkinson-Stiglitz Theorem states that if labor is weakly separable from goods in household utility functions, differential commodity taxation should not be not part of an optimal redistributive tax system. This Theorem, which is arguably the most policy-relevant result to come out of the optimal income tax literature, has come under considerable scrutiny in the literature. We consider how r...

This paper presents a tractable dynamic general equilibrium model that can explain cross-country empirical regularities in geographical mobility, unemployment and labor market institutions. Rational agents vote over unemployment insurance (UI), taking the dynamic distortionary effects of insurance on the performance of the labor market into consideration. Agents with higher cost of moving, i.e....

The Eubank (2012, JDS) findings on taxation, political accountability and foreign aid has had an important influence in academic and policy-making debates. Eubank has warned that his findings should not be generalized across Africa until they are backed by robust empirical evidence. This paper puts some empirical structure to the celebrated literature. The empirical evidence which is based on d...

We construct a political equilibrium in which employers and labour unions bargain over labour contracts, wage-earners and profit-earners lobby the government for taxation and labour market regulation, and labour market legislation must be accepted by the majority of voters. We show that the voters rule out profit sharing, because otherwise the government would capture all the gain. Furthermore,...

The Expansion of Higher Education and Time-Consistent Taxation This paper analyzes educational choices and political support for subsidies to higher education in the presence of a time-consistency problem in income redistribution. There may be political support for so generous subsidization that it motivates the median voter to obtain higher education. As a result of increasing own income, the ...

The Size of the Shadow Economies of 145 Countries all over the World: First Results over the Period 1999 to 2003 Using the DYMIMIC approach, estimates of the shadow economy in 145 developing, transition, developed OECD countries, South Pacific islands and still communist countries are presented. The average size of the shadow economy (in percent of official GDP) over 2002/2003 in developing cou...

We present a simple model of petroleum exploration and development that can be applied to study the performance of alternative tax systems and identify potential distortions. Although the model is a highly simplified, it incorporates many factors and some of the key tradeoffs that would influence an investor’s investment behavior. The model recognizes the role of enhanced oil recovery and treat...

We investigate experimentally the economic effects of wage taxation to finance unemployment benefits for a closed economy and an international economy. The main findings are the following. (i) There is clear evidence of a vicious circle in the dynamic interaction between the wage tax and unemployment. (ii) In the short run employment is boosted by budget deficits. However, subsequent tax rate a...

A benchmark result in the political economy of taxation is that majority voting over a linear income tax schedule will result in an inefficiently high tax rate whenever the median voter has a below average income. The present paper examines the role of tax avoidance for this welfare assessment. We find that the inefficiency in the voting equilibrium is the lower, the higher the average level of...

The aim of this paper is to make a first step towards studying the role of social expenditure and its interaction with corporate taxation in determining the destination of foreign direct investment (FDI) flows. Using panel data for 18 OECD countries and measuring the extent of social welfare policies by the (public social expenditure)/GDP ratio, we find strong support for the conjecture that re...
