We analyze a fully dynamic model of price competition when firms face a learning curve and the possibility of organizational forgetting. We show that even though the leader firm may underprice the follower and this price difference may grow as the leader's cost advantage widens, the market may...

Recent empirical findings have emphasized post entry growth of survivors, as opposed to exit of inefficient and small firms, as the main source of growth over time in the average size of a cohort of entering firms. In this paper, as an explanation for the significant growth of survivors, we...

The paper studies whether “idiosyncratic riskâ€, i.e. the degree to which firm and industry specific returns are more volatile than aggregate market returns, is higher in innovative industries which are characterized by more risk and uncertainty. Volatility is studied both at the...

The paper investigates how the interplay between business cycles and long-run growth shapes the dynamics of economies characterized by financial market imperfections. Most of standard economic literature has centered the analysis of decentralized economies on the representative agent hypothesis...

The paper studies empirically and analytically growth and fluctuation of firm size distribution. An empirical analysis is carried out on several data sets on firm size, with emphasis on one-time distribution as well as growth-rate probability distribution. Two well-known scaling laws, Pareto's...

We have developed an agent-based computational model, extension of an analytical model1 that studies the structure of coalitions of B-to-C web sites, when Internet buyers incur search costs for finding the good that matches their preferences, and coalitions of sites reduce this cost through...

We study a dynamic duopoly model of R\&D to analyze the impact of imperfect appropriability on market structure and welfare. We pursue this analysis by extending the Markov-Perfect dynamic industry model proposed by Ericson and Pakes (EP) (1995), through the introduction of a non-proprietary...

Electricity markets are being liberalised and open to private competition in several countries. These liberalized electricity markets are very complex as the interactions between demand and supply are subject to several technicalities arising from the commodity being traded: electricity. One of...
