The analysis provides a new explanation for two widespread problems concerning European unemployment policy: the disappointingly small effect of many past reform measures on unemployment, and the political difficulties in implementing more extensive reform programs. We argue that the heart of...

Climate mitigation policy should be imposed over a long period, and spur development of new technologies in order to make stabilization of green house gas concentrations economically feasible. The government may announce current and future policy packages that stimulate current R&D in...

This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall life-cycle risk aversion. We provide a...

This paper studies optimal taxation in a general equilibrium macro model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog...

When the government lacks the ability to commit to a tax policy over time, agents' involvement in imperfect financial markets can be welfare improving. Agents borrow against their promised income in markets that are incomplete in the sense that claims cannot be resold without loss. Taking these...

The German Energiewende envisages achieving a climate-neutral building stock in 2050 by means of two major pillars of regulation: First, residential buildings should consume 80% less primary energy and, second, the remaining energy demand should be covered primarily with renewables. This paper...

This paper explores the qualitative and quantitative implications of optimal taxation in a developing economy when economic growth is endogenously determined. We differentiate this class of economies from a developed economy in two aspects: informal sector is quantitatively significant and...

This paper explores the qualitative and quantitative implications of taxation for growth and savings in three Latin American countries: Brazil, Chile and Mexico, studying a small open economy in the context of an endogenous growth model where the domestic interest rate depends on the level of...

At what rate should a government price carbon emissions? This paper analyzes optimal carbon pricing while taking into account interactions with the taxation of labor and capital income. In an otherwise standard climate-economy model, the policy maker has to resort to a distortionary tax on labor...
