We analyze the labor market for painters in Baroque Rome using unique panel data on primary sales of portraits, still lifes, genre paintings, landscapes and figurative paintings. In line with the traditional artistic hierarchy of genres, average price differentials between them were high. The...

We model an international union as a group of countries deciding to centralize the provision of public goods, or policies, that generate externalities across union members. The trade-off between the benefits of coordination and the loss of independent policymaking endogenously determines size,...

I analyze the relation between market size and number of firms when an endogenous number of firms chooses the market strategy and (simultaneously or sequentially) an R&D investment. I generalize the linear Cournot model with an endogenous cost-reducing activity and show that, as long as...

We examine the role of per capita income in closed and open economy models of monopolistic competition based on non-homothetic directly additive preferences a la Dixit-Stiglitz, as in Krugman (1979). In a closed economy with free entry income is always neutral on markups and firm size. In a...

We study monopolistic competition with preferences over differentiated goods characterized by a separable indirect utility rather than a separable direct utility as in the Dixit-Stiglitz model, with the CES case as the only common ground. Examples include linear and log-linear direct demands. In...

We study monopolistic competition under indirect additivity of preferences. This is dual to the Dixit-Stiglitz model, where direct additivity is assumed, with the CES case as the only common ground. Other examples include (perceived) demand functions that are exponential or linear. Our...

Last year, the European Commission proposed a comprehensive reform of the EU’s data protection rules. The proposed regulation has been surrounded by fi erce controversy and has been the subject of frenzied lobbying by global corporations, industry groups, research centres and privacy...
