Cloud computing is a new general purpose Internet-based technology through which information is stored in servers and provided as a service and on-demand to clients. Adopting the endogenous market structures approach to macroeconomics, we analyze the economic impact of the gradual introduction...

We develop a simple model of competition for the market that shows that, contrary to the Arrow view, endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more. We test these predictions with a Tobit model based on a unique dataset...

This article applies the emerging theory of endogenous market structures to macroeconomic issues through a few simple models. First, we study a model of Schumpeterian growth where strategic interactions and endogenous entry determine the equilibrium behaviour of the firms investing in R&D....

I develop a Schumpeterian model where the engine of growth is in the microeconomic structure of the patent races and derive new results on the determinants of growth. Under decreasing marginal productivity in the R&D sector, the equilibrium is characterized by small firms investing too little...

I study a model of geopolitical organization endogenizing the size of nations, of their public spending and of their degree of openness. The optimal geography may not be a stable equilibrium and the Alesina-Spolaore bias toward too many nations tends to be confirmed. However, multiple equilibria...

We analyze art pricing in a unique dataset on Madrid inventories between 1600 and 1750. Hedonic regressions reveal a number of interesting facts about the taste of Baroque Spanish collectors and the imports of foreign paintings. The hedonic price index shows an impressive increase in the price...

Most market structures are neither perfectly or monopolistically competitive: they are characterized by a few large firms that are engaged in strategic interactions in their production and investment decisions and whose number is endogenous. The theory of endogenous market structures analyzes...

We study the seventeenth-century market for figurative paintings in Italy analyzing original contracts between patrons and artists. We show that a number of supply and demand factors affected prices. We find a positive and concave relation between prices and size of paintings reflecting...
