Economies of scale in financial institutions: A general model applied to insurance

This study describes and applies an alternative methodology for measuring economies of scale in financial institutions. A complete model of a profit maximizing financial intermediary is constructed which yields a set of first-order conditions. These together with linear specifications of appropriate revenue and cost functions permit a two-stage estimation of cost and revenue parameters. Application of the model is illustrated by using data from the Canadian general insurance industry. Estimated cost functions suggest (1) that joint stock insurance firms realize no economies of scale from expansion of activity in any one line of insurance but realize diversification economies from writing the same aggregate dollar premiums over appreciably more lines; (2) that mutual companies enjoy direct economies of scale from a simultaneous expansion of insurance lines and, possibly, some diversification economies. Diversification economies may or may not yield special advantages to large firms depending on the competitive state of the reinsurance market.

Reciprocal Reinsurance Treaties

In this paper we shall study the situation of two insurance companies which are negotiating with the view of concluding a reciprocal reinsurance treaty. We assume that the two companies are under no compulsion to reach an agreement. This means that if the companies conclude a treaty, the treaty must be such that both companies consider themselves better off than without any treaty. We futher assume that no third company can break into the negotiations. This means that the two companies either have to come to terms, or be without any reinsurance.How the two parties reach an agreement in a situation like this, is one of the classical problems of theoretical economics. It is usually referred to as the “Bargaining Problem”. The problem appears very simple, but this is a deception. It has proved extremely difficult to formulate generally acceptable assumptions which give the problem a determinate solution. The “Theory of Games”, developed by von Neumann and Morgenstern (10), does not give a determinate solution, but it has greatly increased our understanding of such problems, and the present paper will draw heavily on that theory.The situation which we propose to study, is very simple, may be too simple to have any bearing on reinsurance negotiations in real life. If there exists a reinsurance market, which also is a perfect market in the sense given to this term in economic theory, bartering between two companies does not make any sense. They could both do equally well or better by dealing in the market at the market price.
