| This paper analyses the relation between competition and concentration in the banking sector. The empirical answer is given by testing a monopolistic competition model of bank branching behaviour on individual bank data at county level (départements and provinces) in France and Italy. We propose a measure of the degree of competiveness in each local market that is function also of market structure indicators. We then use the econometric model to evaluate the impact of horizontal mergers among incumbent banks on competition and discuss when, depending on the pre-merger structure of the market and geographic distribution of branches, the merger is anti-competitive. The paper has implications for competition policy as it suggests an applied tool to evaluate... |

| The paper develops a two-stage capacity constrained duopoly model, in which the mode of competition is endogenous and the constraint is flexible, to investigate the impact of Tariff Rate Quotas (TRQs) and their liberalization. The model predicts that the greater the gap between the price of the licences plus the in-quota tariff and the out-of-quota tariff, the closer the outcome of the game to the pure Cournot outcome. The tariff equivalent changes according to the prevailing mode of competition under the TRQ. The model is used to address the issue of the tariffication of the non-ACP TRQ for EU banana imports. The results suggest that under the TRQ firms competed on quantity and that the tariff equivalent is higher than the tariff introduced by the EU in... |

| A residual demand model for beef exports to Japan is specified and estimated. The objective is to estimate the extent of market power. It is assumed that each exporting country faces a downward-sloping residual demand curve, which reflects the market demand minus the supplies of competitors, and that exporters maximize profit through their output decisions. The analysis is disaggregated by beef cut and form to capture the variation by beef market segments. The results indicate that the highest markup of price over marginal cost belongs to U.S. frozen ribs, the only indication of market power by U.S. exporters. Canada is found to have limited market power, whereas Australia and New Zealand enjoy some market power, including five chilled beef categories. |

| This paper considers vertical restraints in a multi-market retail setting in which each retailer sells the complete line of manufactured goods. Vertical restraints by one manufacturer on the retailers of its product serve as an instrument to exert horizontal control over the retail price of a rival manufactured good. Applications are developed for supermarket retailing, where the manufacturer of a national brand sold at both supermarkets can employ vertical restraints to control the pricing of the retailer's competing private labels, and for the personal computer industry, where the manufacturer of an essential computer component can use vertical restraints to control the pricing of complementary components bundled with the essential component by... |

| Wal-Mart, the largest retailer worldwide, has been suspected of exercising market power over input providers, both merchandise suppliers and workers. However, in spite of a growing body of literature investigating the beneficial economic impact of the company through its price-lowering effect, research analyzing the company’s economic impact over input suppliers is limited. This paper presents a general framework which can be used to investigate Wal-Mart’s market power over input suppliers, vis-à-vis a variation in input productivity, focusing on homogenous intermediate goods supplied locally. The model is general enough to account for incumbents’ reaction to Wal-Mart’s entry resulting in exit, entry and changes in the production technology. A simplified... |

| Despite the increasing importance of market power in the food industry, most policy models assume perfect competition. Ignoring market power may lead economists to make incorrect, or at least misleading, policy recommendations. In this paper I develop a theoretical model in which market power can alter conclusions regarding the welfare effects of a specific policy change: replacing deficiency payments with decoupled payments to farmers, and apply it to the U.S. wheat market and milling industry. The main conclusions of the theoretical model are that, middlemens market power may cause i) an increase in public expenditure, ii) an extraction of policy rents from the taxpayers by the middlemen, and iii) a reduction of the social benefit from decoupling... |

| Ultra-hazardous risky activities as nuclear industry cannot be considered as “normal industries” i.e. industries without abnormal environmental and health risks. Consequently, the industrial organization of these specific sectors is of the utmost importance. This paper aims at studying this question. We focus on the associated costs of prevention and civil liability. We analyze how civil liability rules may contribute to extend or to discourage the expansion of nuclear parks to new operators. The paper compares the consequences of extending the management of nuclear stations to several independent operators. This question can apply to the unification process of the European electricity market in which several public and private nuclear power operators are... |

| The typical situation faced by antitrust authorities is to analyze and rule on a proposed merger by two or more manufacturers using scanner data at retail-level in a particular industry. This paper presents a simple framework to assess merger welfare effects in markets where both upstream and downstream firms make pricing decisions. I start with a benchmark model of manufacturers’ and retailers’ sequential pricing behavior. Then using counterfactual experiments, I explore the relationship between downstream retailer pricing models and the resulting estimates of upstream mergers. This exercise is done in the absence of wholesale prices looking at scanner data for the ground coffee category sold at several retail chains in Germany. I find that not... |

| Corn markets are important for many industries. These include the seed, fertilizer, meat production/processing and agricultural machinery sectors, all of which are highly concentrated. Oligopoly theory suggests that corn input and field equipment suppliers likely benefit from policies that support corn markets, such as U.S. biofuels policy, while meat companies likely lose. This study investigates the impact of biofuels policy on U.S. agribusiness stock prices. Corn futures prices are found to have a structural change in November 2006, consistent with the expansion of U.S. biofuels policy support. A linear two-factor (S&P500 and corn prices) equilibrium asset pricing model is estimated on two subsamples, one before and one after the estimated change... |
