ABSTRACT
The efficient management of resources is one of the principal tasks of economic theory. One of the foundations of economics is to seek the greatest possible output with the minimum input. The limits on resources thus constitute a problem which must be faced. Conversely, an abundance of resources is an opportunity to be exploited. This also holds good in relation to different choices and buying options. Starting from the assumption that consumers are capable of evaluating the characteristics of the products and services available on the market, the greater the number of options available, the greater the chance that the most suitable offer will be found. A multiplicity of options thus signifies an increase in the expected utility of choice.
