We analyse the question of optimal taxation in a dual economy, when the policy-maker is concerned about the distribution of labour income. Income inequality is caused by the presence of sunk capital investments, which creates a ‘good jobs’ sector due to the capture of quasi-rents by trade...

We use data from a television game show, involving elementary lotteries and substantial prize money, as a natural experiment to measure risk attitudes. We find robust evidence of substantial risk aversion. As an extension, we esimate the various models using transformations of the ‘true’...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

Economists traditionally tackle normative problems by computing optimal policy, ie the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I call...

This paper studies optimal taxation of entrepreneurial capital and financial assets in economies with private information. Returns to entrepreneurial capital are risky and depend on entrepreneurs’ effort, which is not observed. The presence of idiosyncratic risk in capital returns implies that...

The aim of this Paper is to test for the extent of incompleteness in the market for US Government debt. We show that when a government pursues an optimal tax policy and issues a full set of contingent claims, the value of debt has the same or less persistence than other variables in the economy...
