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 measures of background, ability, and attitudes, including lottery experiments measuring risk attitudes. Consistent with the International Labor Organization's views of the self employed (represented by Tokman), the analysis finds that two-thirds to three-quarters of the own account workers have characteristics which are more like wage workers than larger firm owners. This suggests the majority of the own account workers are unlikely to become employers. Using a two and a half year panel of enterprises, the authors show that the minority of own account workers who are more like larger firm owners are more likely to expand by adding paid employees. The results suggest that finance is not the sole constraint to growth of microenterprises, and provides an explanation for the low rates of growth of enterprises supported by microlending.

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 measurement of profits. The authors report on a variety of different experiments conducted to better understand the importance of some of these problems and to draw recommendations for collecting profit data. In particular, they (1) examine how far we can reconcile self-reported profits and reports of revenue minus expenses through more detailed questions; (2) examine recall errors in sales and report on the results of experiments which randomly allocated account books to firms; and (3) ask firms how much firms like theirs underreport sales in surveys like this, and have research assistants observe the firms at random times 15-16 times during a month to provide measures for comparison. The authors conclude that firms underreport revenues by about 30 percent, that account diaries have significant effects on both revenues and expenses but not on profits, and that simply asking profits provides a more accurate measure of firm profits than detailed questions on revenues and expenses.

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, measuring the return to capital is complicated by unobserved factors such as entrepreneurial ability and demand shocks, which are likely to be correlated with capital stock. The authors use a randomized experiment to overcome this problem and to measure the return to capital for the average microenterprise in their sample, regardless of whether they apply for credit. They accomplish this by providing cash and equipment grants to small firms in Sri Lanka, and measuring the increase in profits arising from this exogenous (positive) shock to capital stock. After controlling for possible spillover effects, the authors find the average real return to capital to be 5.7 percent a month, substantially higher than the market interest rate. They then examine the heterogeneity of treatment effects to explore whether missing credit markets or missing insurance markets are the most likely cause of the high returns. Returns are found to vary with entrepreneurial ability and with measures of other sources of cash within the household, but not to vary with risk aversion or uncertainty.

Many microenterprises in developing countries have high returns to capital, but also face risky revenue streams. In principle, equity offers several advantages over debt when financing investments of this nature, but the use of equity in practice has been largely limited to investments in much larger firms. The authors develop a model contract to make self-liquidating, quasi-equity investments in microenterprises. This contract has three key parameters that can be used to shift risk between the entrepreneur and the investor, resulting in a continuum of contracts ranging from a debt-like contract that shifts little risk from the entrepreneur to a pure revenue-sharing contract in which the investor absorbs much more of the risk. The paper discusses implementation choices, and then provides lessons from a proof-of-concept carried out by an investment partner, KGC Equity, which made nine investments averaging USD 3,800 in Sri Lankan microenterprises. This pilot demonstrates that this new contract structure can work in practice, but also highlights the difficulties of micro-equity investments in an environment with weak contract enforcement.

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 levels and stock flow in small retail firms in Sri Lanka. In principle, the tags offer the potential to track stock movements accurately. The paper compares the stock counts obtained from RFID reads to physical stock counts and to survey responses. There are three main findings. First, current RFID-technology is more difficult to use, and more time-consuming to employ, than had been envisaged. Second, the technology works reasonably well for paper products, but very poorly for most products sold by microenterprises: on average only about one-quarter of the products tagged could be read and there was considerable day-to-day variation in read-efficiency. Third, a comparison of survey responses and physical stock-takes shows much higher accuracy for survey measures. As a result, the study concludes that this technology is currently unsuitable for improving stock measurement in microenterprises, except perhaps for a few products.
