Over the last twenty years we have seen an increasing use of in-work tax subsidies to encourage labor supply among low-income groups. In Sweden, a non-targeted earned income tax credit was introduced in 2007, and was reinforced in 2008, 2009 and 2010. The stated motive of the reform was to boost...

The basic idea in this paper is that labor supply can be viewed as a function of the entire budget set, so that one way to account non-parametrically for a nonlinear budget set is to estimate a nonparametric regression where the variable in the regression is the budget set. In the special case...

This note extends the work by Sørensen (2005) and others by demonstrating why the Norwegian Shareholder Income Tax may be neutral between the two sources of equity funds, i.e. new share issues and retained earnings, despite the fact that the retention of earnings to finance new investment does...

We explore the implications of heterogeneity in the elasticity of taxable income (ETI) for tax-reform based estimation methods. We theoretically show that existing methods yield elasticities that are biased and lack policy relevance. We illustrate the empirical importance of our theoretical...

We examine how tax avoidance in the form of trade in well-functioning asset markets affects the basic labor supply model. We show that tax arbitrage has dramatic implications for positive, normative and econometric analysis of how taxes affect work incentives.

In recent years, the study of how individuals respond to policies that aim at promoting pension savings has emerged as a vital area of economic research. This paper adds to this literature by estimating the tax price elasticity of contributions to tax-favoured pension savings accounts on a...

Conventional models of equilibrium unemployment typically imply that proportional taxes on labor earnings are neutral with respect to unemployment as long as the tax does not affect the replacement rate provided by unemployment insurance, i.e., unemployment benefits relative to after-tax...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...
