Upstream Merger in a Successive Oligopoly: Who Pays the Price?
(), Lars Sørgard
() and Simen A. Ulsaker
Abstract: This study develops and uses a successive oligopoly model,
with an unobservable non-linear tariff between upstream and downstream
firms, to analyze the possible anti-competitive effects of an upstream
merger. We nd that an upstream merger may lead to higher average prices
paid by downstream firms, but that there is no change in the prices paid by
consumers. The model is tested empirically on data for an upstream merger
in the Norwegian food sector (specifically, the market for eggs).
Consistent with the theoretical predictions of the model, we find that the
merger had no effect on consumer prices, but led to higher average prices
from the downstream to the upstream firm.
