Co-production and reversed cream-skimming in quasi-markets

In this paper, we provide a very simple model to shed light on the issue of managed competition in mixed quasi-markets (i.e. regulated markets in which social and for-profit firms coexist). In doing this, we consider the literature on mixed oligopolies as a reasonable reference point and try to enrich it with the idea of quasi-market. Firstly, our results show that social firms serve the relatively richer portion of the population. Only relatively poor consumers buy units of service from the profit-oriented firm. Secondly, the socially-preferable form of managed competition is to introduce coproduction practices and, hence, to raise profit-oriented firm's production costs. The diffusion of coproduction paradigms ensures maximal service quality and eliminates mark-up from the market.
