Moral Hazard in Reinsurance Markets

This article attempts to identify moral hazard in the traditional reinsurance market. We build a multiperiod principal–agent model of the reinsurance transaction from which we derive predictions on premium design, monitoring, loss control, and insurer risk retention. We then use panel data on U.S. property liability reinsurance to test the model. The empirical results are consistent with the model's predictions. In particular, we find evidence for the use of loss‐sensitive premiums when the insurer and reinsurer are not affiliates (i.e., not part of the same financial group), but little or no use of monitoring. In contrast, we find evidence for the extensive use of monitoring when the insurer and reinsurer are affiliates, where monitoring costs are lower.     

Economic policy in Sweden: are there lessons from the Swedish model?

This article reviews Swedish economic policy since 1960 in the light of the trade union's Rehn-Meidner model. The arguments of economists who blame the crisis of the Swedish economy in the 1970s on that model are critically reviewed. The maintenance of full employment is analysed. The policies of the Social Democratic government since 1982 are found to be significantly at variance with the Rehn-Meidner model leading to a high risk of wage-push inflation. It is suggested that the British labour movement has lessons to learn from Swedish experience and the Rehn-Meidner model in particular.     

A SIMPLIFIED APPROACH TO SHORT-TERM INTERNATIONAL DIVERSIFICATION

Using Eurocurrency deposit interest rates, currency exchange rates, and inflation rates in a mean-variance portfolio analysis, the authors develop portfolios of interest-bearing deposits in London banks denominated in various currencies. These easily constructed multicurrency portfolios are shown to provide better risk-return positions than comparable single currency holdings.     

Scale and scope economies of Australian permanent building societies in a dynamic framework

In this paper we examine the interrelationship between technological change, branching, and the multi-product cost structure of Australian Permanent Building Societies within a dynamic specification of the cost function. The results strongly support this dynamic formulation, though the speed of adjustment of costs to long-run levels is quite fast. We also find evidence of economies of scale for small societies, suggesting some potential for smaller societies to benefit from increased scale through mergers.
