Expense preference behavior in mutual life insurers

The effect of alternative ownership structures, stock versus mutual, on the cost of production is studied for firms in the life insurance industry. The effect of differential incentives on the cost structure of both groups of firms is examined by means of a multiproduct cost function. This research shows that despite differences in legal form and incentives of managers, stock and mutual firms in the life insurance industry are similar in terms of the types of products sold, the average cost of production, and the form of the relationship between cost and production.Department of Finance, University of Connecticut
