We investigate the effects of passive backward acquisitions in their efficient upstream supplier on downstream firms' ability to collude in a dynamic game of price competition with homogeneous goods. We find that passive backward acquisitions impede downstream collusion. The main driver of our...

We estimate the spillovers on firm profitability and market shares in oligopolistic markets through the transition from an n to an n-1 player oligopoly after a merger in the industry. Competitors are identified via the European Commission s market investigations and our methodology allows us to...

In 2003, the UK Competition Commission (CC) approved the acquisition of Safeway plc by Wm. Morrisons plc, respectively the fourth and sixth largest firms in the industry. Because Morrisons focused on the North and Safeway on the South, this merger had the potential to create a fourth national...

This paper investigates the effects of mergers, entry, and exit in retail markets when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between manufacturers and retailers which allows for general forms of demand and retail competition. Whether...

This Supplemental Material includes, among other things, the analytical derivatives of the price-cost margins of manufacturers determined via the "Nash-in-Nash" bargaining solution, the computation of the out-of-equilibrium retail prices following a bargaining breakdown, the algorithm used to...

This paper investigates the effects of changes in retail market concentration when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between upstream and downstream firms which allows for general forms of demand and retail competition. Whether...

We develop a framework of bilateral oligopoly with a sequential two-stage game in which manufacturers engage in bilateral bargains with retailers competing on a downstream market. We show that bargaining outcomes depend on three different bargaining forces and can be interpreted in terms of...

The law and economics literature on the tragedy of the anticommons suggests that producers of complementary goods should integrate themselves. Recent decisions by the antitrust authorities seem to indicate that there is tradeoff between the “tragedy” and the lack of competition which might...

Moresi and Salop (2013) have extended the “upward pricing pressure” approach used in analyzing horizontal mergers to the analysis of vertical mergers. They present test expressions called the vGUPPIu and vGUPPId to see if the upstream and downstream prices will rise as a result of the...
