This paper investigates the effectiveness of antitrust policy in fighting horizontal collusion under different regimes of policy implementation. We consider two regimes : a public agency regime, where an antitrust authority is in charge of competition policy, and a "delegation" regime, where the...

In a simple economic setting with asymmetric information we compare different social insti- tutions which fight against industry cartels on prices. Firstly, we analyse the case where an Antitrust Authority is created and we distinguish two situations depending whether the agency has the...

In a two period model with asymmetric information we study the optimalantitrust policies carried out by a public agency faced with firms'horizontal price-fixing behaviour. We analyse the effect on social welfare in case the Antitrust Authority decides to bind itself to follow the same policy, an...

This paper investigates the process of GDP generation in Former Soviet Union (FSU) economies to provide understanding of the impact of technology channels on countries’ efficiency. We apply a stochastic frontier approach to 15 FSU economies over the period 1995–2008, and we find that...

This paper investigates the strategic choice between introducing a process or a product innovation in a duopoly model with vertical differentiation, comparing the outcomes in case of Bertrand and Cournot competition. It is shown that under both competitive regimes three equilibria in innovation...
