We provide a method allowing to identify margins in an oligopoly price competition game when prices may not be freely chosen in some markets, for example due to regulation. We use our identification strategy to study the effects of regulatory constraints in the pharmaceutical industry, which is...

Although naive intuition may indicate the opposite, the existing literature suggests that uncertainty about costs in the homogeneous-good Bertrand model intensifies competition: it lowers price and raises total surplus (but also makes profits go up). Those results, however, are derived under two...

In this paper, we adopt the vertical differentiation duopoly framework to give a full description of firms’ relocation decisions, when the removal either of trade barriers or of restrictions on capital outflows/inflows (‘globalization’) allows them to serve the domestic market through...

This paper examines optimal policy towards a home exporting firm which competes on price with a foreign firm. Two policy instruments are compared: an output subsidy and a price subsidy. The paper also considers two games: the conventional ex ante game, in which the government sets the value of...

This paper investigates the interaction of firms' financial structure and their competitive behaviour on oligopolistic product markets. We consider risk-averse entrepreneurs who produce with uncertain production costs. To reduce their exposure to risk they can sell stocks to risk-neutral...

The British electricity supply industry has, with the exception of Nuclear Electric, now been privatized. Bulk supplies of electricity are traded between two dominant generators and many suppliers in an unregulated `pool'. The generators submit a supply schedule of prices for each generating set...

In this paper, we consider a European industry characterized by vertical product differentiation. Using a two-stage model with quality choice made before price competition takes place, we show that EU anti-dumping policy that takes the form of price-undertakings offers a powerful protection to...

This paper investigates the possibility of endogenous fluctuations in the international distribution of economic activities in the presence of increasing returns, monopolistic competition, trade and convex adjustment costs without allowing for any local productive externalities. Using a...

After a brief review of classical, Keynesian, New Classical and New Keynesian theories of macroeconomic policy, we assess whether New Keynesian Economics captures the quintessential features stressed by JM Keynes. Particular attention is paid to Keynesian features omitted in New Keynesian...

This Paper develops a model in which the interaction between product market imperfections, transportation costs, unions and workers immobility across regions creates a tendency for agglomeration of firms when transportation costs are low. The model fits quite well the European experience. It is...
