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...

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...

A global multi-sectoral, multi-regional computational general equilibrium model is employed to assess carbon taxes under perfect competition and monopoly. We found that regional studies of carbon taxation maybe inaccurate due to the carbon emission spillover effects. Emission taxes have stronger...

Gibrat's Law of proportionate effect, as applied to firms, states that the growth rate of a firm is independent of its size. Empirical work on firm dynamics finds crucial deviations from Gibrat's Law such as smaller firms growing faster than larger firms (Evans, 1987, and Hall, 1987), a negative...
