Abstract

This paper illustrates that the cost of regulation can be negative when regulation-induced innovation has a stochastic element. There are two aspects to this finding. First, if the firm is risk neutral then regulation necessarily raises expected costs but costs can be lower ex post for some realizations of the innovation process. Whether this cost reduction is most likely for unfavourable or favourable realizations of the stochastic element depends on whether good fortune and research effort are substitutes or complements in the innovation process. The second aspect involves the implications of risk aversion and risk preference. In both cases it is possible for regulation to reduce costs on average because the regulation can induce the firm to undertake a level of research closer to that which minimizes expected cost. Cette étude démontre que le coût de la réglementation peut être négatif quand l’innovation induite par la réglementation a un élément stochastique. Ce résultat comporte deux aspects. Premièrement, si l’entreprise est neutre envers le risque, la réglementation fait nécessairement augmenter les coûts attendus, mais les coûts peuvent être inférieurs ex post pour certaines réalisations du processus d’innovation. Le fait que cette réduction de coûts sera plus probable pour des réalisations favorables ou défavorables de l’élément stochastique dépend de ce que la chance et l’effort de recherche sont des substituts ou des compléments du processus d’innovation. Le second aspect met en cause les implications de l’aversion au risque ou du goût pour le risque. Dans les deux cas, il est possible que la réglementation fasse diminuer les coûts en moyenne puisqu’elle peut inciter la firme à entreprendre un niveau de recherche plus proche de celui qui minimise le coût espéré.
