In many economic applications involving comparisons of multivariate distributions, supermodularity of an objective function is a natural property for capturing a preference for greater interdependence. One multivariate distribution dominates another according to the `supermodular stochastic...

We develop a model of human capital formation with endogenous labour supply and heterogeneous agents to explore the optimal level of education subsidies along with the optimal progressive schedule of the labour income tax and optimal capital income taxes. Subsidies on education ensure efficiency...

We analyze the impact of micro-founded political institutions on economic growth in an overlapping-generations economy, where individuals differ in preferences over a public good (as well as in age). Labour and capital taxes finance the public good and a public input. The benchmark institution...

We develop a general equilibrium model that jointly considers the influence of capital accumulation constraints and of labour market frictions on the process of transition. We endogenize the economic and budgetary costs of different government policies and show that, early in transition,...

This paper presents evidence of profit shifting in response to differences in corporate tax rates for a large selection of OECD countries. In our estimates we control for the effects of tax rate changes on real activity. Our baseline estimates suggest that, on average, a unilateral increase in...

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...

This Paper explores the effects of a menu of inter-generational fiscal policies (public debt financed by taxes, PAYG social security system and inheritance taxation) in an overlapping generations model with perfect altruism. It generalizes the model by Barro (1974) by introducing...

Income redistribution often takes highly inefficient forms, such as employment in the bureaucracy. We argue that this arises as an optimal political strategy in situations where politicians cannot commit to policies. Political exchanges between politicians and voters must be self-enforcing and...

In thinking about policy, academic economists alternate between theoretical models in which governments can design finely-tuned optimal interventions and practical considerations which usually assume the government to be incompetent and hostage to special interests. I argue in this paper that...
