PROFITABILITY, UNCERTAINTY, AND FIRM SIZE

This paper examines the connections between variations in profit and loss rates among firms in small-firm and large-firm size classes as reflections of uncertainty. We find that, within industries, such variations are particularly great for firms in small-firm size classes, leading to operating policies for small firms best characterized as entrepreneurial. Large firms, in contrast, faced with less uncertainty in earning profit, appear to adopt policies that manifest an emphasis on strategic planning.
