Restructuring of the Dutch Nonlife Insurance Industry: Consolidation,Organizational Form,and Focus

Since the deregulation of the European insurance market in 1994, Dutch nonlife insurance firms have sized up and increased their focus. Concurrently, the stock organizational form has become increasingly dominant. This article investigates these 1995–2005 trends from a cost‐efficiency perspective. We observe substantial economies of scale that are even larger for smaller firms. In line with the efficient structure hypothesis, both stocks and mutuals are found to have comparative cost advantages. Supporting the strategic focus hypothesis, we find that more specialized insurers have lower costs. Thick frontier efficiency estimates point to large cost X‐inefficiencies that have moderately decreased over time.
