Abstract

Cross section regressions are used to evaluate the extent of economies of scale in the property-liability insurance industry prior to 1978 and to explain the increased number of mergers between 1978 and 1981 in the Quebec market. The second and third section of this paper discusses the appropriate approach to the problem of measuring economies of scale in the insurance industry. The fourth section describes the data and the empirical results. À l’aide d’une analyse de régression en coupe instantanée l’auteur tente de mesurer l’importance des économies de dimensions dans l’industrie des assurances générales avant 1978 et d’expliquer l’augmentation des fusions dans cette industrie, au Québec, entre 1978 et 1981. Les deuxième et troisième sections portent sur la question du choix d’une approche pertinente au problème de mesure des économies de dimension dans cette industrie. La dernière partie présente les résultats empiriques.
