We provide a methodology to study the role of market distortions on the emergence of indeterminacy and bifurcations. Most of the specific market imperfections considered in the related literature are particular cases of our framework. Comparing them we obtain several equivalence results in terms...

We document contemporaneous differences in the aggregate labor supply of married couples across 17 European countries and the US. Based on a model of joint household decision making, we quantify the contribution of international differences in non-linear labor income taxes and consumption taxes...

Many nations are seeking to reform their welfare states so that costs to the government can be reduced and the quality of outcomes improved. As a potential way to achieve these aims, there has been a surge of interest in the Singaporean model which features compulsory savings accounts and...

We study the link between tax progressivity and top income shares. Using variation from large-scale Western tax reforms in the 1980s and 1990s and the novel synthetic control method, we find large and lasting boosting impacts on top income shares from the progressivity reductions. Effects are...

We compile data spanning the period 1900 2014 and up to 30 countries to study long-run patterns in the tax elasticity of top incomes. Our results show that top tax elasticities vary tremendously over time; they were medium-to-low before 1950, virtually zero during the postwar era up to 1980 and...

Discrete-choice models provide a simple way of representing utility-maximizing labor supply decisions in the presence of highly nonlinear and possibly non-convex budget constraints. Thus, it is not surprising that they are so extensively used for ex-ante evaluation of taxbenefit reforms. The...
