In this work we analyze the relationship between the patterns of firm diversification, if any, across product lines and across bodies of innovative knowledge, proxied by the patent classes where the firm is present. Putting it more emphatically we investigate the relationship between "what a...

This paper analyses the relation between firms' productivity and the different modes of participation to international trade. In particular, we account for the possibility that firms can not only export their products, but also internationally source their inputs, either directly or indirectly....

This article explores the dynamics of market selection by investigating of the relationships linking productivity, profitability, investment and growth, based on China's manufacturing firm-level dataset over the period 1998-2007. First, we find that productivity variations, rather than relative...

This paper provides a simply theory to explain the impact of sanctions on a regime’s policies and behavior. Sanctions are generally put to strip the target country from its available rents and weaken the government’s stance against growing discontent in the population. We show however that...

We consider the interplay between income distribution and optimal commodity taxation, linking equity issues to optimal taxes through the effect of income distribution on market demand and its price elasticity. We find conditions to conciliate the equity and efficiency tradeoff and to assess the...

This paper presents an analytical model of the dynamic interrelationships between education, creativity, and happiness based on both theoretical insights and recent empirical neurological studies. In the model, the outcome is conditional on individual intelligence and risk aversion....

This paper examines the impact of intellectual property rights (IPR) enforcement on multinationals’ choice of input suppliers and industry profits in a host economy. The framework consists of suppliers with heterogeneous capabilities who must engage in a relation-specific investment to...

We model an industry in which a discrete number of firms choose the output of their differentiated products deciding whether or not to consider the impact of their decisions on aggregate output. We show that two threshold numbers of firms exist such that: below the lower one there is a unique...

We show that the standard argument according to which supply function equilibria rank intermediate between Bertrand and Cournot equilibria may be reversed. We prove this result within a static oligopolistic game in which both supply function competition and Cournot competition yield a unique...

This paper aims at participating in the long-lasting debate about the analytical foundations of the Cournot equilibrium. In a homogeneous oligopoly, under standard regularity conditions, we prove that Cournot-Nash emerges both under (i) price competition and Cournot conjectures; and (ii) supply...
