Do Wages Rise or Fall Following Merger?

Abstract

This paper provides a systematic empirical analysis of the effects of merger and acquisition activity on profitability and firm-level employee remuneration in the UK, using a specially constructed database for the period 1979-91. It finds that both profitability and wages rise following acquisition, and firms that merge within the same industry division experience larger increases in profitability and pay their workers higher wages than those engaged in unrelated acquisitions; i.e. in part, the result of an increase in the efficiency with which labour is used following related acquisition.
