This paper studies models where the optimal response functions under consideration are non-increasing in endogenous variables, and weakly increasing in exogenous parameters. Such models include games with strategic substitutes, and include cases where additionally, some variables may be...

We find the optimal capital income tax rate in an imperfectly competitive economy, where some part of recourses is devoted to rent-seeking activity. Optimal tax offsets the difference between marginal social and marginal private return to capital, which is a result of rent seeking, and the...

We explore various aspects of mergers and acquisitions in the banking industry within a simple model that allows explicit comparison of sector performance before and after the mergers and acquisitions. The industry structure we look at involves a few dominant banks and a competitive fringe,...

The paper show how changes in the state of credit may cause instability in the output and in the employment levels. The model revised Delli Gatti and Gallegati's version of the contribution by Greenwald and Stiglitz (1993) in a contest characterized by imperfect competition in the goods market...

This paper shows that the results of Bucci (2003) depend criti- cally on the assumption that there are no difference between the intermediate goods share in final output, the returns of specialization and the degree of market power of monopolistic competitors. In this paper, we disentangle the...

An extensive empirical literature indicates that returns from innovation are appropriated primarily via mechanisms other than formal intellectual property rights -- and that `imitation' is itself a costly activity. However most theory assumes the pure nonrivalry of `ideas' with its implication...

The aim of this paper is to analyze the relationship between competition and growth in a model of human capital accumulation and research by disentangling the monopolistic mark-up in the intermediate goods sector and the returns to specialization in order to have a better measure of competition....

The aim of this paper is to analyse the relationship between competition and growth in an endogenous growth model with expanding product variety without scale effect. In order to do this, we develop an extension of the Bucci (2005) model in which we eliminate the scale effects. We find that the...

This paper shows that the results of Bucci (2005) depend critically on the assumption that there are no difference between the intermediate goods share in final output, the returns of specialization and the degree of market power of monopolistic competitors. In this paper, we disentangle the...

In line with economic theory, carbon ETS determines a rise in marginal cost equal to the carbon opportunity cost regardless of whether carbon allowances are allocated free of charge or not. Hence, common sense would suggest that .rms in imperfectly competitive markets will pass-through into...
