This study attempts to identify the factors affecting the growth of companies listed on the Alternative
Investment Market (AIM), the London Stock Exchange’s market dedicated to young and growing companies.
We investigate the post IPO growth of a panel consisting of 665 companies listed on the AIM from 1995 to 2006.
Our empirical model is estimated using the GMM - System (GMM - SYS) estimator.
Our findings confirm that small companies listed on the AIM grow at a faster rate after the IPO.
It seems that both human capital and firm characteristics are important determinants of their fast growth.
The results of this study carry some policy implications. Policy makers could take into account the relevance of
an efficient financial system.
Moreover, it is important to look at the process of transformation in the cultural and behavioural attitudes of
many countries towards entrepreneurship.
