A popular way of obtaining essential inputs requires the establishment of an input production joint venture (IPJV) in the upstream (U) section of the vertical chain of production by firms competing and selling final goods in the downstream (D) section of the vertical chain. In spite of the...

A popular way of obtaining essential inputs is based on the establishment of an input production joint venture (IPJV) in the upstream (U) section of the vertical chain of production by firms competing and selling final goods downstream (D). Different governances may be designed for the...

In this paper, we present a model of endogenous vertical integration and horizontal differentiation. Thereexists two output brands and two versions of the input. The only mean for output differentiation is the inputversion used in output production. Firms may choose to vertically integrate to...
