Indivisibilities and the Insurace Buying Gambler

Is it possible to name an insurance buyer as a risk averse and a gambler as a risk lover? And what about the insurance buying gambler? Friedman and Savage (1948), claimed that households are risk averse up to a certain income level, risk lover later and again risk averse thereafter. In the literature there are many extensions or objections to this idea. These discussions can be separated into three parts: indivisibilities and market constraints, labour markets and the consumption value of the gambling. In this paper, indivisibility problem and the shortcomings of the financial markets to overcome this problem is discussed. Instead of offering a solution or a new approach, a chain is tried to be established between the approaches to make the discussion more clear, simple and applicable especially for the bankers. Not only the excuses for the phenomenon but also the objections are analysed in detail. Since the insurance buying gambler exists and seems to exist to an infinite future, it is and will be very important to understand the behaviour of the investors and also to test the certain portfolio theories.
