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...

Using a Mortensen-Pissarides search-and-matching framework, this paper investigates the importance of search frictions in determining the welfare and distributional effects of tax reforms that re-allocate the tax burden from capital to labour income. Calibrating the model to the UK economy, we...

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...

This paper evaluates the effects of policy interventions on sectoral labour markets and the aggregate economy in a business cycle model with search and matching frictions. We extend the canonical model by including capital-skill complementarity in production, labour markets with skilled and...

We extend the canonical model of search and matching frictions by including capital-skill complementarity in production, labour markets with skilled and unskilled workers and on-the-job-learning (OJL) within and across skill types. These extensions capture key characteristics of skilled and...
