Mergers With Supply Functions

Author

  • Uğur Akgün

Abstract

I analyze the equilibrium effects of a merger in an industry when firms compete by submitting supply functions. Under the assumptions that the industry capital stock is fixed and production costs are quadratic and decreasing in capital, I find that any merger results in all firms reducing supply. The decrease in supply by non‐participating firms makes any merger profitable. A merger from a symmetric industry lowers welfare.
