Title: Corporate demand for insurance
Description: "Using a unique dataset of insurance decisions by over 1,800 large U.S.  corporations, this study provides the first empirical analysis of firm behavior that compares corporate demand for property and catastrophe insurance (here, terrorism).  We combine demand and supply data and apply a simultaneous-equation approach to address the problem of endogenous premium decisions.  The main finding is that demand for property and catastrophe insurance are not very different and that the demand for catastrophe coverage is actually more price inelastic.  We also show that a corporation's ability to self-insure affects the demand for catastrophe insurance but not for property insurance"--National Bureau of Economic Research web site.
