Socialism: An Economic and Sociological Analysis

The merger of several similar independent establishments into one enterprise may be called horizontal concentration of production. Here we follow broadly the usage of writers on cartels, though their definition is not in complete accord with ours. If the separate establishments do not remain completely independent, if, for example the management or some departments are amalgamated, there is concentration of establishments. A mere concentration of enterprises occurs only when the individual units remain independent in everything except the taking of decisive economic decisions. The typical example of this is a cartel or a syndicate. Everything stays as it was, but, according to whether it is a buying cartel or a selling cartel or both, decisions about purchases and sales are taken unitarily.

When it is not merely the preliminary step to an amalgamation of establishments, the purpose of these unions is monopolistic domination of the market. Horizontal concentration originates only in the efforts of separate entrepreneurs to derive those advantages enjoyed under certain circumstances by the monopolist.
