Markets are an example of a paradigm of a self-generating or spontaneous social order (Hayek 1973, p. 37), i.e. social arrangements in which participants` activities are spontaneously coordinated, through mutual adaptation or adaptation of separate decision-makers, without conscious and central direction. In this sense, the market order “as a particular type of social structure” (Swedberg 1994, p. 255) may be opposed to the deliberate and centralized coordination of activities within companies or organizations, i.e. within social entities such as “family, factory, factory, business, company, company and all associations, as well as all public institutions, including governments” (1973). 46). One of the central themes of F. A. Hayek`s work is that the distinction between the “two types of order” (Hayek 1973, p. 46), the market and the organization (Vanberg 1982) is fundamental to an adequate understanding of the nature of social phenomena in general and market order in particular. The lack of adequate recognition of the nature of the market as a spontaneous social order is, according to Hayek, a great source of confusion in discussions on economic theory, and in particular on economic policy, confusion which he attributes in part to the ambiguity that is implied when the term “economy” is used to describe the market order.

Since the term is derived from the Greek word oikonomia, which means domestic economy, “an economy in the strict sense is an organization or agreement in which someone deliberately assigns resources to a unit order of the extremities” (Hayek 1978, p. 178). To avoid misleading connotations, Hayek proposes not to refer to the market order as an economy, but as a catallaxie – derived from the Greek word katallatein, which means “exchange” (Hayek 1976, p. 108). It is often difficult to reach mutual agreement through a negotiation process. This article explains how institutions can reduce this difficulty. It begins with a fundamental dichotomy of bargaining situations between zero-sum and mixed-sum cases. This dichotomy is then linked to the diversity of products – public, CPR, club and private – that the players want to manufacture through negotiation.
