Lás microempresas, así como los proveedores de productos, enfrentan desventajas en comparación con las empresas más grandes respecto al abastecimiento de inventario porque, para reabastecerse, deben viajar con frecuencia y pagar costos más altos. Los investigadores evaluaron Agruppa, un servicio de tecnología que usa teléfonos móviles, el cual crea grupos virtuales de compradores para comprar a granel de forma más económica. La evaluación descubrió que la demanda inicial del servicio era alta, lo que ahorraba tiempo y gastos a los dueños de negocios, y aumentaba las ganancias de ciertos productos básicos. Sin embargo, dado que los dueños de negocios redujeron las ventas de otros productos, los ingresos y las ganancias cayeron en promedio y la demanda del servicio disminuyó con el tiempo. Agruppa finalmente cerró, lo que evidencia los desafíos de competir contra mercados centralizados.

Differences in management quality are an important contributor to productivity differences across countries. A key question is how to best improve poor management in developing countries. This paper tests two different approaches to improving management in Colombian auto parts firms. The first uses intensive and expensive one-on-one consulting, while the second draws on agricultural extension approaches to provide consulting to small groups of firms at approximately one-third of the cost of the individual approach. Both approaches lead to improvements in management practices of a similar magnitude (8–10 percentage points), so that the new group-based approach dominates on a cost-benefit basis. Moreover, the paper finds some evidence that the group-based intervention led to increases in firm size over the next three years, while the impacts on firm outcomes are smaller and statistically insignificant for the individual consulting. The results point to the potential of group-based approaches as a pathway to scaling up management improvements.

Las pequeñas y mediana empresas son vistas como importantes motores de crecimiento en los países en desarrollo. Sin embargo, barreras al crecimiento tales como la dificultad para acceder a créditos impiden con frecuencia el desarrollo de ese potencial. Ante este panorama, un grupo de investigadores usó una evaluación aleatorizada para medir el impacto de introducir puntajes de crédito generados por computador sobre los niveles de créditos otorgados a las micro y pequeñas empresas en Colombia. La evaluación reveló que el programa incrementó significativamente la productividad en la aprobación de créditos y mejoró su asignación sin afectar el promedio de los montos autorizados ni las tasas de incumplimiento.

Evaluations of employment programs usually focus on direct impacts on participants, but potential indirect effects are rarely quantified. This paper analyzes the impact of a subsidized apprenticeship program in Côte d’Ivoire. The experiment simultaneously randomized whether apprenticeship positions opened by firms were filled by the program, and whether interested youths were assigned to a formal apprenticeship. This design allows for estimating whether individuals forgo other apprenticeship opportunities (windfall effects), and whether firms replace other apprentices with program participants (substitution effects). We find both effects to be moderate. A framework shows how they combine: overall, 0.74 to 0.77 apprenticeship position is created per subsidized apprentice. Short term impacts on youth earnings were not significant. However, the net value of work provided by apprentices in firms increased, pointing to large indirect effects of the program.

We organized business associations for the owner-managers of young Chinese firms to study the effect of business networks on firm performance. We randomized 2,820 firms into small groups whose managers held monthly meetings for one year, and into a “no-meetings” control group. We find the following. (i) The meetings increased firm revenue by 8.1%, and also significantly increased profit, factors, inputs, the number of partners, borrowing, and a management score. (ii) These effects persisted one year after the conclusion of the meetings. (iii) Firms randomized to have better peers exhibited higher growth. We exploit additional interventions to document concrete channels. (iv) Managers shared exogenous business-relevant information, particularly when they were not competitors, showing that the meetings facilitated learning from peers. (v) Managers created more business partnerships in the regular than in other one-time meetings, showing that the meetings improved supplier-client matching.

Several field experiments find positive returns to grants for male and not female microentrepreneurs. But, these analyses largely overlook that male and female micro-entrepreneurs often belong to the same household. Using data from randomized trials in India, Sri Lanka and Ghana, we show that the gender gap in microenterprise performance is not due to a gap in aptitude. Instead, low average returns of female-run enterprises are observed because women’s capital is invested into their husbands’ enterprises rather than their own. When women are the sole household enterprise operator, capital shocks lead to large increases in profits. Household-level income gains are equivalent regardless of the grant or loan recipient’s gender.

A randomized control trial with 432 small and medium enterprises in Mexico shows positive impact of access to 1 year of management consulting services on total factor productivity and return on assets. Owners also had an increase in “entrepreneurial spirit” (an index that measures entrepreneurial confidence and goal setting). Using Mexican social security data, we find a persistent large increase (about 50 percent) in the number of employees and total wage bill even 5 years after the program. We document large heterogeneity in the specific managerial practices that improved as a result of the consulting, with the most prominent being marketing, financial accounting, and longterm business planning.

The Small and Medium Enterprise (SME) Program at IPA discovers and promotes effective solutions to the constraints faced by entrepreneurs and SMEs in developing countries. SMEs are the largest generators of employment in the developing world, creating nearly 60% of new jobs. They also generate a myriad of opportunities across sectors and geographic areas, and employ broad and diverse segments of the labor force. SMEs in developing countries, however, face constraints that are disproportionately large compared to those faced by larger firms and by SMEs in developed countries. Limited access to finance, low levels of human capital, and difficulty accessing markets stand out as some of the most challenging barriers to business growth.

We use a field experiment to show referral-based hiring has the potential to disadvantage qualified women, highlighting another potential channel behind gender disparities in the labor market. Through a recruitment drive for a firm in Malawi, we look at men's and women's referral choices under different incentives and constraints. We find that men systematically refer few women, despite being able to refer qualified women when explicitly asked for female candidates. Performance pay also did not alter men's tendencies to refer men. Additionally, women did not refer enough high quality women to offset men's behavior.

This paper studies the impact on well-being and business outcomes from teaching stress-management practices to small firm owners in Bangladesh. Female owners were randomly assigned either to a treatment group that received a 10-week Cognitive Behavioral Therapy (CBT) course featuring priority-setting and relaxation techniques, or to a control group exposed to Empathic Listening. CBT leads to large initial reductions in owner stress, but no initial increase in firm profits. Six months after receiving CBT, owners in sectors with a low concentration of women show large and significant effects on stress, and their firms show increased profits. By contrast, owners in female-dominated sectors experience a short-lived reduction in stress, and firms show no changes in profits. The large post-treatment differences in well-being and profits between industries suggest that the ability to manage stress is malleable, and that industry choice proxies for traits that are strongly correlated with returns to training.

We conduct a randomized experiment that generates exogenous variation in the access to foreign markets for rug producers in Egypt. Combined with detailed survey data, we causally identify the impact of exporting on firm performance. Treatment firms report 16–26% higher profits and exhibit large improvements in quality alongside reductions in output per hour relative to control firms. These findings do not simply reflect firms being offered higher margins to manufacture high-quality products that take longer to produce. Instead, we find evidence of learning-by-exporting whereby exporting improves technical efficiency. First, treatment firms have higher productivity and quality after controlling for rug specifications. Second, when asked to produce an identical domestic rug using the same inputs and same capital equipment, treatment firms produce higher quality rugs despite no difference in production time. Third, treatment firms exhibit learning curves over time. Finally, we document knowledge transfers with quality increasing most along the specific dimensions that the knowledge pertained to.
