This Paper discusses the role of public policy towards the venture capital industry. The model emphasises four margins: supply of entrepreneurs due to career choice, entry of venture capital funds and search for investment opportunities, simultaneous entrepreneurial effort and managerial advice...

We completely characterize the set of second-best optimal "menus" of student-loan contracts in a simple economy with risky labour-market outcomes, adverse selection, moral hazard and risk aversion. The model combines structured student loans and an elementary optimal income-tax problem à la...

We characterize optimal redistribution in a dynastic family model with human capital. We show how a government can improve the trade-off between equality and incentives by changing the amount of observable human capital. We provide an intuitive decomposition for the wedge between human-capital...

We study a setting with search frictions in the marriage market and with incomplete contracting inside the family. Everyone prefers a partner that has a high income and is a perfect emotional match, but compromises must often be struck. A high-income earner may abstain from marrying a low-income...

The Ramsey optimal taxation theory implies that the tax rate on capital income should be zero in the long run. This result holds even if the social planner only cares about workers that do not hold assets, or if the planner only cares about any other group in the economy. This paper demonstrates...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labour productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial...

In the coming decades, the share of people in working age will fall significantly in most developed countries. According to optimal taxation theory, public debts should be reduced before the baby-boom generation retires. I find that if debts are instead maintained at the current levels, welfare...

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...

In this Paper, we take the field of optimal dynamic taxation further in two directions. Using a model with invisible labour, as in Hansen (1986) and Rogerson (1988), we first explore the short-run dynamics of the capital-income tax, particularly whether the tax, under the second-best programme,...

Gender Based Taxation (GBT) satisfies Ramsey’s optimal criterion by taxing less the more elastic labour supply of (married) women. This holds when different elasticities between men and women are taken as exogenous and primitive. But in this paper we also explore differences in gender...
