We evaluate the social welfare loss (WL) that arises in an oligopolistic industry under technological competition and product differentiation. The main novelty of our approach concerns the decomposition of the WL into `dynamic' losses (from too little cost reduction and an inappropriate number...

We find that trade unions have a rational incentive to oppose the adoption of labour-saving technology when labour demand is inelastic and unions care much for employment relative to wages. Trade liberalization typically increases trade union technology opposition. These conclusions are reached...

This Paper studies the effect of knowledge diffusion on the incentives for developed countries’ (DC) firms to undertake costly transfer of production knowledge of an input to their developing countries’ (LDC) suppliers whose costs of production vary inversely with their technological effort....

We use cumulative reaction functions to compare long-run market structures in aggregative oligopoly games. We first compile an IO toolkit for aggregative games. We show strong neutrality properties across market structures. The aggregator stays the same, despite changes in the number of firms...

The paper offers a new theoretical framework to examine the role of intermediaries between creators and users of new inventions. We find that uncertainty about the profitability of investing in new inventions generates a basis for intermediation. An intermediary may provide an opportunity to...

This paper empirically investigates the effects of the US safeguard protection on steel imports in 2002 on the mark-ups of EU steel producers. We identify a large panel of EU steel producers between 1995 and 2005 affected by the safeguards. Using the Roeger methodology, our results show that the...

Trading in futures markets has grown substantially for many commodities. At the same time the power of many dominant producers has weakened and core prices have tended to fall towards those on the fringe. Existing cartel/fringe models fail to explain the difference between core and fringe prices...

We endogenize the market risk (at given technical risk) in firms’ R&D decisions by introducing stochastic R&D in the Hotelling model. It is shown that if the technical risk is sufficiently high, the market risk remains low even if firms pursue similar projects. This leads firms to focus on the...

This Paper characterises the unique Markov equilibrium in the sequential move, finite horizon pricing duopoly with discounting. Simple, short cycles repeat until the last two periods. For discount factors above 0.75488, there are three-period reaction function cycles and below 0.75488,...
