We present the first comprehensive evidence on the health impacts of the introduction and expansion of a large non-contributory health insurance program in Mexico, the Seguro Popular (SP). SP provided access to health services without co-pays to individuals with no Social Security protection. To...

This paper estimates the marginal efficiency cost of redistribution (MECR) associated with a demogrant and an in-work benefit for the UK since 1979, taking account of extensive as well as intensive labour supply responses. The principal methodological advance in the paper is its greater...

Value added taxes (VAT) are an important, and in many cases increasing, source of revenue in both developed and developing countries. Unsurprisingly there is an intense academic and policy debate about the appropriate VAT rate structure, for both equity and efficiency reasons. In this paper we...

Heterogeneity is likely to be an important determinant of the shape of optimal tax schemes. This article addresses the issue in a model à la Mirrlees with a continuum of agents. The agents differ in their productivities and opportunity costs of work, but their labor supplies depend only on a...

We study optimal taxation in the general extensive model: the only decision of the participants in the economy is to choose between working (full time) or staying inactive. People differ in their productivities and in other features which determine their work opportunity costs. The qualitative...

We study optimal corrective taxation in the alcohol market. Consumption generates negative externalities that are non-linear in the total amount of alcohol consumed. If tastes for products are heterogeneous and correlated with marginal externalities, then varying tax rates on different products...
