This presentation summarizes Gregg's recent research on Imperial Russian commercial law, finance, and industrial productivity. By the early twentieth century, the Imperial Russian economy still lagged behind Western European levels of development but was growing rapidly. Gregg's larger project seeks to understand how the Imperial government's industrial policies, for example restricting the creation of large corporations, affected the development of the Russian industrial sector. Her results are obtained from two large databases describing individual firms in the Russian Empire: one describes all industrial firms in 1894, 1900, and 1908, and another describes every corporation on an annual basis from 1900 to 1914. With this new data, some classic, stubborn questions can now be answered. For example, results demonstrate that Russia's concession system of incorporation held back industrial development and that, conditional on obtaining a corporate charter, Russian corporations behaved reasonably competitively.
