Since a fairly large number of regression coefficients linking selected explanatory variables
to financial performance is reported in the literature, this form of meta-analysis is
feasible. We use 8 sets of regression coefficients as dependent variables in 8 separate
ANCOVAs. Each of the ANCOVAs documents the relationship of one of the following
variables to financial performance: industry concentration, market share, growth, advertising,
research and development (R&D), size (log and 1 /log) and capital investment
intensity. Financial performance measures comprise all types of profit return measures
(e.g., on assets, equity); other performance measures are either not compatible or infrequently
found.
