In what form should the Intellectual Property Rights (IPR) be treated in an endogenous growth model? What are the effects of introducing IPR into a North-South endogenous growth model? In this paper, we develop a general equilibrium endogenous growth model that emphasizes the IPR enforcement...

The acknowledged importance of innovation and the increasingly decisive role played by the service sector make innovation an issue of major relevance to the economy. Using a sample of 6593 companies that answered the Community Innovation Survey 2008, we assessed the determinants of innovation of...

The Hop-constrained Minimum cost Flow Spanning Tree (HMFST) problem is an extension of the Hop-Constrained Minimum Spanning Tree problem since it considers flow requirements other than unit flows. Given that we consider the total costs to be nonlinearly flow dependent with a fixed-charge...

This paper develops an empirical approach using econometric techniques for panel data which aims to contribute to the reduction/elimination of the deviation between the book and market value of firms. Based on 20 of the firms with the largest number of patents granted between 1996 and 2006, the...

The participation of businessmen in official visits done by Heads of State or Government is a way found by official authorities to promote exports and the internationalization of the firms. There is a large body of literature about export promotion and the evaluation of export promotion...

We study the effect of quadratic differentiation costs in the Hotelling model of endogenous product differentiation. The equilibrium location choices are found to depend on the magnitude of the differentiation costs (relatively to the transportation costs supported by consumers). When the...

Recently bibliometrics techniques are being widely used to complement traditional qualitative reviews of the literature in given scientific areas. The majority of these reviews are based in large databases of articles published in ISI indexed journals, overlooking the richness of studies that...

We revisit the issue of self-fulfilling “waves of enthusiasm” as stationary rational expectations equilibrium outcomes in endogenous-growth models that merge the quality-ladders with the expanding-variety mechanism. By considering a lab-equipment specification with vertical-innovation...

Using a longitudinal matched employer-employee data set for Portugal over the 1986-2005 period, this study analyzes the heterogeneity in wages responses to aggregate labor market conditions for newly hired workers and existing workers. Accounting for both worker and firm heterogeneity, the data...

Private state verification is introduced in a two-period economy with spot markets in both periods and complete futures markets for contingent delivery in the second period. Existence of equilibrium is established, under standard assumptions. An example is presented in which a complete set of...
