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...

We characterize the optimal export promoting policies for international markets whose structure is endogenous. Contrary to the ambiguous results of strategic trade policy for markets with a fixed number of firms, it is always optimal to subsidize exports as long as entry is endogenous, under...

This article derives antitrust implications for markets where entry can be regarded as endogenous (contrary to most analysis within the post-Chicago tradition). Many applications concern issues of abuse of dominance. Endogenous entry requires a wide revision of our understanding of the role of...

I study Public-Private Partnerships (PPP) as investments in public infrastructures that are alternative compared to direct public investments. I consider different forms of PPP, discussing their relative advantages from the point of view of incomplete contract theory and principal-agent...

I provide theory and evidence on the relation between public infrastructures and growth. I develop an OLG model of endogenous growth with a production function including both private and public capital, where the latter is the result of investments in infrastructures. With high substitutability...

This paper analyzes market structures where leaders have a first mover advantage and entry by the followers is endogenous. The strategy of the leaders is always more aggressive than the strategy of the followers independently from strategic substitutability or complementarity. Under quantity...

This paper provides a general characterization of optimal export promoting policies for foreign competitive markets and apply it to strategic trade policy and exchange rate policy. Contrary to the ambiguous results of strategic trade policy under barriers to entry in the third market, I find...

The EMSs approach to macroeconomics introduces strategic interactions and endogenous entry decisions in the analysis of aggregate phenomena as business cycle, international trade and growth. This survey provides a non-technical discussion of the applications of the EMSs approach to positive and...

The EMSs approach to macroeconomics introduces strategic interactions and en- dogenous entry decisions in the analysis of aggregate phenomena. This approach departs from the perfectly competitive environment, in the sense that rms do not take prices as given, but they do choose their entry and...

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 than the average firm. We test these predictions with a Tobit model...
