In West Africa, the Value Added Tax (VAT) policy consists of a uniform tax rate, but several items consumed by rich and poor households, are exempted. We provide an optimal tax framework to reflect on the welfare effects of such a tariff structure, in the context of current debates on domestic...

We study the optimal design of spatially-differentiated subsidies for residential solar panels. We build a structural model of solar panel demand and electricity production across the US and estimate the model by combining 1) remotely sensed data on residential solar panels, 2) power-plant-level...

What are the implications of (endogenous) directed technical change for the design of redistributive income taxes? I study this question in a Mirrleesian economy augmented to include endogenous technology development and adoption choices by firms. Under certain conditions, any progressive tax...

By inverting Saez (2002)’s model of optimal income taxation, we characterize theredistributive preferences of the Irish government between 1987 and 2005. The (marginal)social welfare function revealed by this approach is consistently comparable over time andshow great stability despite...

This paper characterizes optimal income taxation when individuals respond along both theintensive and extensive margins. Individuals are heterogeneous across two dimensions:specifically, their skill and disutility of participation. Preferences over consumption and workeffort can differ with...

Paternalism, merit goods and specific egalitarianism are concepts we sometimes meet in the literature. The thing in common is that the policy maker does not fully respect the consumer sovereignty principle and designs policies according to some other criterion than individuals? preferences....

Research in behavioral economics has uncovered the widespread phenomenon of people making decisions against their own good intentions. In these situations, the government might want to intervene, indeed individuals might want the government to intervene, to induce behavior that is closer to what...

By inverting Saez (2002)'s model of optimal income taxation, we characterize the redistributive preferences of the Irish government between 1987 and 2005. The (marginal) social welfare function revealed by this approach is consistently comparable over time and show great stability despite...

The paper characterizes the optimal tax policy and the optimal quality of day care services in a OLG model with warm-glow altruism where parental choices over child care arrangements affect the probability that the child becomes a high-skilled adult in a type-specific way. With respect 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...
