This paper investigates economies of scope in the US insurance industry over the period 1993-2006. We test the conglomeration hypothesis, which holds that firms can optimize by operating a diversity of businesses, versus the strategic focus hypothesis, which holds that firms can best add value...

We distinguish between the hypotheses using profit scope economies, which measures the relative efficiency of joint versus...

This paper analyzes the efficiency of stock and mutual organizational forms in the property-liability insurance industry using nonparametric frontier efficiency methods. We test the managerial discretion hypothesis, which predicts that the market will sort organizational forms into market...

Reinsurance is the primary source of interconnectedness in the insurance industry. As such, reinsurance connectivity provides a transmission mechanism for financial shocks and potentially exposes insurers to contagion and systemic risk. In this paper, connectivity within the U.S....
