Innovation is key to technology adoption and creation, and to explaining the vast differences in productivity across and within countries. Despite the central role of the entrepreneur in the innovation process, data limitations have restricted standard analysis of the determinants of innovation...

In a recent randomized experiment we found mean returns to capital of between 5 and 6 percent per month in Sri Lankan microenterprises, much higher than market interest rates. But returns were found to be much higher among men than among women, and indeed were not different from zero for women....

This paper analyzes data from a randomized experiment on mean returns to capital in SriLankan micro-enterprises. The findings show greater returns among men than among women; indeed, returns were not different from zero for women. The authors explore different explanations for the lower returns...

Using data from surveys of enterprises in Sri Lanka after the December 2004 tsunami, the authors undertake the first microeconomic study of the recovery of the private firms in a developing country following a major natural disaster. Disaster recovery in low-income countries is characterized by...

Accurate measurement of stock levels, turnover, and profitability in microenterprises in developing countries is difficult because the majority of these firms do not keep detailed records. This paper tests the use of radio frequency identification tags as a means of objectively measuring stock...

Is the vast army of the self-employed in low income countries a source of employment generation? This paper uses data from surveys in Sri Lanka to compare the characteristics of own account workers (non-employers) with wage workers and with owners of larger firms. The authors use a rich set of...

Small and informal firms account for a large share of employment in developing countries. The rapid expansion of microfinance services is based on the belief that these firms have productive investment opportunities and can enjoy high returns to capital if given the opportunity. However,...

A large share of the world's poor is self-employed. Accurate measurement of profits from microenterprises is therefore critical for studying poverty and inequality, measuring the returns to education, and evaluating the success of microfinance programs. But a myriad of problems plague the...

Small-scale entrepreneurs typically cite access to finance as the most important constraint to growth. Recent randomized experiments have shown the return to capital to be very high for the average microenterprise in Sri Lanka. An intervention was designed to improve access to credit among these...

A field experiment in Sri Lanka provides informal firms incentives to formalize. Information about the registration process and reimbursement of direct costs does not increase registration. Payments equivalent to one-half to one month (alternatively, two months) of the median firm's profits...
