We evaluate the welfare impact of changing the VAT on food in a context in which households can produce home meals for own consumption that compete with meals served in restaurants. Home production of meals requires the combination of food and time inputs. The fiscal treatment in home production...

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...

Der Klimawandel zählt zu den größten Herausforderungen der Automobilindustrie. Obgleich eine Fülle technologischer Ansätze vorhanden sind, erreicht die europäische Automobilindustrie nicht ihre selbstgesteckten Ziele zur Verringerung der CO2-Emissionen. Ein wichtiger Grund hierfür ist die...

In the last decades, substantial changes have occurred regarding what scientists consider the limits of habitable environmental conditions. For every extreme environmental condition investigated, a variety of microorganisms have shown that not only can they tolerate these conditions, but that...

La tasa óptima de impuesto a los ingresos de capital en Estados Unidos es 36% según Conesa y otros (2009). Este resultado se deriva de un modelo de ciclo de vida y se debe a la existencia de mercado incompletos y a la oferta laboral endógena. Se muestra que este modelo tiene problemas en...

This paper studies the determination of informal long-term care (family aid) to dependent elderly in a worst case scenario concerning the “harmony” of family relations. Children are purely selfish, and neither side can make credible commitments (which rules out efficient bargaining). The...

This paper presents the properties of optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction between second earner wage differences, variation in the price of child care and...

We study implications of habit formation for optimal taxation. First, we show that taxation problems with habit formation can be analyzed using dynamic programming techniques. Second, we derive optimal labor and savings wedges for habit formation preferences. We show that habit formation...

This paper examines the question of achieving a societal consensus around redistributive policies. Its extent is measured by the degree of work participation among the different skill classes that populate the economy. This consensus is driven both by the material incentives and heterogeneous...
