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...

Americans work more than Europeans. Using micro data from the U.S. and 17 European countries, we study the contributions from demographic subgroups to these aggregate level differences. We document that women are typically the largest contributors to the discrepancy in work hours. We also...

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...

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...
