The use of e-commerce around the world has accelerated in recent years, with Asia, led by China, spearheading the rise. Using cross-country enterprise survey data, this paper shows that firms engaged in e-commerce have higher productivity and generate a larger share of their revenues from exports than other firms. This is particularly true in Asia, where firms have 30 percent higher productivity and generate about 50 percent more of their revenues from exports. The results presented in this paper are robust to the use of instrumental variables, which highlight possible larger effects of e-commerce on Asian productivity and exports when essential elements are in place for its effective use, such as reliable electricity, telecommunication, and transport infrastructure. Despite the rapid growth of e-commerce in recent years, gaps persist in digital infrastructure and legislation, preventing many Asian countries from fully reaping the potential benefits of e-commerce.
An influential theoretical literature has observed that economic diversification can reduce risk and increase financial development. But causality operates in both directions, as a well functioning financial system can enable a society to invest in more productive but risky projects, thereby determining the degree of economic diversification. Thus, ordinary least squares (OLS) estimates of the impact of economic diversification on financial development are likely to be biased. Motivated by the economic geography literature, this paper uses instruments derived from topographical characteristics to estimate the impact of economic diversification on the development of finance. The fourth estimates suggest a large and robust role for diversification in shaping financial development. And these results imply that, by impeding financial sector development, the concentration of economic activity common in developing countries can adversely affect financial and economic development.
