The relationship between ownership structure and corporate performance has
been the subject of intense research in both transition and market economie
s. The Czech Republic's mass-privatization program provides an unique oppor
tunity to investigate this relationship. It changed the ownership of firms
in a short period of time, and firm characteristics had only a limited infl
uence on the resulting ownership structure. For a cross section of 706 Czec
h firms over the period 1992 through 1997, we find that the mon concentrate
d the ownership, the higher the firm profitability and labor productivity.
These findings are weakly robust to the inclusion of control variables for
the type of ownership, or to a correction for the endogeneity of ownership
concentration. (C) 1999 Academic Press.
