This paper contains a brief survey of recent empirical work on the per
formance of large companies. It tries to pull together the literature
in the form of six stylized facts, illustrating them with data drawn f
rom a single sample. The paper concludes by highlighting the issues wh
ich are thrown up for future work. These are: accounting for persisten
t heterogeneities between firms, accounting for the apparently erratic
performance of many firms and, finally, moving away from hypothesis t
esting driven empirical agendas.
