There is often a gap between the prescriptions of an "optimal" tax system and actual tax systems, some of which can be neither efficient economically nor efficient at redistributing income. With a focus on personal income taxes, this paper reviews the political economics literature on tax...

This paper presents a case study on reforming a very dysfunctional labour market with a deep insider-outsider divide, namely the Spanish case. We show how a dual market, with permanent and temporary employees makes real reform much harder, and leads to purely marginal changes that do not alter...

We derive conditions of individual preferences and technology that give rise to a negative correlation between income inequality and environmental protection. We present a class of models (which captures a static model as well as an overlapping-generations model) in which individuals differ in...

Empirical evidence on the relationship between democracy and economic reforms is scarce, limited to few reforms and countries and for few years. This paper studies the impact of democracy on the adoption of economic reforms using a new dataset on reforms in the financial, capital, public, and...
