Market Games in Successive Oligopolies

This paper introduces a new approach to successive oligopolies. We draw on market games à la Shapley–Shubik to examine how successive oligopolies operate between downstream and upstream markets when the input price is determined by the action of all firms, downstream and upstream both. This approach differs from the classical one as it allows us to consider downstream firms that exercise market power both in both downstream and upstream markets. We perform a comparison of the market outcome with each scenarios as well as a welfare analysis.
