In this paper, we develop heterogeneous agent models with equilibrium unemployment to study the optimal taxation and labour wedge. We find that the the presence of profits plays an important role in the determination of both optimal tax policy and labour wedge. Judd-Chamley optimal zero capital...

In this paper we examine the importance of imperfect competition in product and labour markets in determining the long-run welfare effects of tax reforms assuming agent heterogeneity in capital holdings. Each of these market failures, independently, results in welfare losses for at least a...

Using a two-agent model comprised of capitalists and workers, this paper examines the importance of imperfect competition in product and labour markets in determining the welfare effects of tax reform. The reform considered consists of eliminating the capital tax alongside a concurrent rise in...

Using data from the 1981 Family Expenditure Survey we estimate a logit model for the choice between unemployment and employment, using explanatory variables such as tax and social security benefit rates. Other variables represent the characteristics of the households in the survey and...

We analyse the impact of increased immigration on labour market outcomes of natives in Germany using a dataset of county-level variables for the late 1980s. We study two measures of immigration, the change in the share of foreigners between 1985 and 1989, and one-year gross and net flows of...

Budget constraints are drawn up for annual hours and net pay, typically composed of two linear segments: 'benefit-constrained', where extra work forfeits benefit and 'normal', where extra work is subject to the standard marginal tax rate. There are additional linear segments for those on upper...
