Long-range dependence in volatility is one of the most prominent examples of applications in financial market research involving universal power laws. Its characterization has recently spurred attempts at theoretical explanation of the underlying mechanism. This paper contributes to this recent...

We investigate for evidence of complex-deterministic dynamics in financial returns time series. By combining the Surrogate Data Analysis inferential framework with the MG-GARCH (Kyrtsou and Terraza, 2003) modelling approach, we examine whether the sequences are characterized by aperiodic and...

This paper analyzes a financial market with noise trading and momentum trading, and shows how momentum trading affects the market equilibrium. When momentum traders dominate the market, whether trend-chasing or contrarian, the private information owned by informed trader is not incorporated into...

Markets for digital information goods provide the possibility of exploring new and more complex pricing schemes, due to information goods' flexibility and negligible marginal cost. In this paper we compare the dynamic performance of price schedules of varying complexity under two different...

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...

We discuss the identification and estimation of discrete games with complete information. Following Bresnahan and Reiss, a discrete game is defined to be a generalization of a standard discrete choice model in which utility depends on the actions of other players. Using recent algorithms that...

We build a dynamic duopoly model that accounts for the empirical observation of monopoly persistence in the long run. More specifically, we analyze the conditions under which it is optimal for the market leader in an initially duopoly setup to undertake pre-emptive R&D investment, ("strategic...

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...

The damage caused by the economic activities is one of the major problems of the world. On the one hand, countries try to support their own firms and motivate FDI by protectionist trade policies, and on the other hand, they try to protect environment via environmental policies. In this paper, we...
