Introduction

Competition policy, as framed by governments, is directed towards those firms with “market power”. Because large firms are more likely than small firms to be able to influence market prices, it is the former that have been the focus of attention of national, and sometimes international, competition authorities.

The prime role of competition policy, certainly in the United Kingdom, has been to seek to benefit consumers, and to have large firms as its key target. In contrast, small and medium-sized enterprises (SMEs) are viewed as more likely to be the victims, rather than the perpetrators, of anti-competitive practices.

So, although there has been considerable research undertaken on the impact of competition policy upon (large) enterprises and upon consumers (see Motta 2004 for a review), there is almost no UK-based work that examines any link between competition policy and SMEs.

Small and Large Firms

Storey and Greene (2010) argue that, other than pure scale, SMEs are different from larger enterprises in several important respects. First, SMEs normally lack any form of market power. In other words, by changing their output, they are unable to influence prices in their marketplace. Second, SMEs are very unlikely to be able to restrict or eliminate the entry of new firms in their markets. So, if they develop a profitable niche, it is very unlikely that they will be able to prevent another firm entering that marketplace to compete against them.
