Abstract

Computer mediated transactions ([Varian, 2010]) allow insurance companies to customize their contracts while transaction costs limits this tendency toward customization. To capture this, we develop a complete-information framework in which it is costly to design a new market segment when the segmentation policy (number and design of segments) is endogenously chosen. Both the case of a private and a public insurer are considered. Without transaction cost, these two insurance systems are equivalent in terms of social welfare and participation. With transaction costs, this equivalence is not anymore true and the analysis of this difference is the subject of this article.
