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....

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...

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 characterize the optimal unilateral trade policy for domestic firms competing in domestic or integrated markets with endogenous entry of foreign firms. Under conditions satisfied in most trade models (as with quasi-linear or Dixit-Stiglitz preferences), the analysis is simplified by a...

With strategic interactions and endogenous entry in a market, opening up to trade creates gains under very general conditions. Under Dixit-Stiglitz preferences and Cournot (or Bertrand) competition, an expansion of the market size induces exit of domestic firms, lower prices and larger...

We study the impact of a General Purpose Technology that changes the cost structure turning fixed costs into variable ones in most sectors. A major recent example is cloud computing, whose adoption allows firms to avoid large up-front costs in IT and to rent computing capability online. We study...

We analyze the evolution of the price of paintings in the XVII century Amsterdam art market to test a hypothesis of endogenous entry: higher probability should attract more entry of painters, which in turn should lead to artistic innovations and more intense competition. We build a price index...
