Losses of Welfare and Market Power in the French Food Industry by Pascal Lavergne, Vincent Réquillart and Michel Simioni
We study the practical problems of estimating losses of welfare resulting from market power. Particular attention is paid to the specification of demand functions, the evaluation of deviations between marginal costs and prices and the calculation of Hicksian losses of welfare. We evaluate the losses of welfare for 31 French food sectors and show that the Marshallian consumers' surplus measurement is a good approximation of the Hicksian surplus measurement. However, the Marshallian loss of welfare measurement does not provide a good approximation of the corresponding Hicksian measurement. Lastly, the different approximations of the marginal cost-price deviation produce considerably different sector rankings by extent of losses of welfare. Source : Éditeur (via Persée) |
