Institutions are made up of (and by) individuals and function based on the collective individuals' need to maximize utility. Therefore, similar economic and social hierarchies and institutions exist in both prison and the outside world.

Three major institutions found to facilitate markets in Oflag are social, economic, and political institutions.
The man-made institutions that most directly facilitated the operations of the markets were the social and economic institutions. Because provisions were allocated without regard to individual needs and demands, trade was immediately necessary. The P.O.W.s initially established Exchange and Mart notice boards, which created an open trading market, and this provided a semi-permanent paper trial of various commodities' past and current asking/selling prices, relative to cigarettes. Cigarettes became the established currency, and over time, a general consensus was established.
