Large-scale risks and technological change: What about limited liability?


Sandrine Spaeter, BETA, University of Strasbourg

We consider a firm that has to choose a technology to produce a given good. This technology drives a multiplicative large-scale risk of incident for Society: the total potential level of damage increases with the level of activity. Contrary to what is often argued in the literature, first we show that limited liability can be more incentive for technical change than an unlimited liability rule, depending on the magnitude of the technological change and on the firm's size. Second, we show that an appropriate tax policy relative to the technological choice made by the firms increases the number of firms that make technological change under a limited liability rule. This technological change is welfare improving and it leads, under fair conditions, to full risk internalization despite the limited liability rule. Our normative results provide some arguments in favor of this rule, often considered as the main explanation of partial large-scale risk internalization by firms.
