Horizontal Mergers with Capital Adjustment: Workers' Cooperatives and the Merger Paradox

Abstract

We study the incentives towards horizontal merger among firms when the amount of capital is the strategic variable. We focus on is workers' cooperatives, but our conclusions apply also to employment-constrained profit maximisers. Within a simple oligopoly model, we prove that the horizontal merger, for any merger size, is: (i) privately efficient for insiders as well as for outsiders; (ii) socially efficient if market size is large enough, even in the case of merger to monopoly.
