%0 Report %A Bertola, Giuseppe %A Koeniger, Winfried %T Hidden Insurance in a Moral Hazard Economy %D 2013 %8 2013 Dec %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 7806 %U https://www.iza.org/publications/dp7806 %X We consider an economy where individuals privately choose effort and trade competitively priced securities that pay off with effort-determined probability. We show that if insurance against a negative shock is sufficiently incomplete, then standard functional form restrictions ensure that individual objective functions are optimized by an effort and insurance combination that is unique and satisfies first- and second-order conditions. Modeling insurance incompleteness in terms of costly production of private insurance services, we characterize the constrained inefficiency arising in general equilibrium from competitive pricing of nonexclusive financial contracts. %K first-order approach %K principal agent %K hidden action %K constrained efficiency
