I illustrate that the welfare improvement property of the Melitz model is due to the shape of the aggregate labor demand curve, which slopes upwards. By slightly changing some assumptions in the model, this curve may have a negative slope. In this case, increases in aggregate productivity result...

We examine the efficiency properties of labor taxation. A spatial model of an economy is introduced whose key feature is a new approach to restricted labor mobility. We characterize the efficient allocation of labor and properties of a decentralized equilibrium. An efficient allocation of labor...

Entrepreneurs who decide to enter an industry are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy. What is not well understood is how international trade affects the government incentive to impact on entry costs,...

The optimal mix of growth policies is derived within a comprehensive endogenous growth model. The analysis captures important elements of the tax-transfer system and takes into account transitional dynamics. Currently, for calculating corporate taxable income US firms are allowed to deduct...

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...

How will international integration affect welfare policies? This paper considers the possibilities of financing public sector activities (public consumption and social security expenses) by general (wage) taxation in an economy which becomes more integrated in international product markets. Even...

For patriotic citizens, living in their native country is intrinsically preferable compared to living in the diaspora. In this paper, we analyze the implications of such a patriotic lock-in in a world with international migration and redistributive taxation. In a formal model of redistribution...

We document the time-series of employment rates and hours worked per employed by married couples in the US and seven European countries (Belgium, France, Germany, Italy, the Netherlands, Portugal, and the UK) from the early 1980s through 2016. Relying on a model of joint household labor supply...
