The majority of enterprises in many developing countries have no paid workers. This paper reports on a field experiment conducted in Sri Lanka that provided wage subsidies to randomly chosen microenterprises to test whether hiring additional labor would benefit such firms. In the presence of labor market frictions, a short-term subsidy could have a lasting impact on firm employment. Using 12 rounds of surveys to track dynamics four years after the end of the subsidy, the study finds that firms increased employment during the subsidy period, but there was no lasting impact on employment, profitability, or sales. Two supplementary interventions and treatment heterogeneity suggest the lack of impact is not due to complementarities with capital or management skills, and detailed survey data help rule out a number of theoretical mechanisms that could result in sub-optimally low employment. The study concludes that the urban labor market facing microenterprises does not have large frictions that would prevent own-account workers from becoming employers.

This paper uses a randomized controlled trial to study the effects of access to agent banking. Individuals were encouraged to open an account and transact at a banking agent or a branch of a financial institution. Compared with individuals who were sent to the branch, individuals sent to an agent increased the number of transactions and incurred lower transaction costs with the agent. These transactions are, however, only half as large as those made at the branch because branch tellers are less likely to share information about clients with others. Banking with agents thus entails a trade-off between lower transaction costs and lack of privacy.

This paper investigates an alternative proxy for individual worker productivity in physical work settings: a direct measure of physical activity using an accelerometer. First, the paper compares worker labor outcomes, such as labor supply and daily productivity obtained from firm personnel data, with physical activity; they are strongly related. Second, the paper investigates the effect of a health intervention on physical activity, using a temporally randomized offer of malaria testing and treatment. Workers who are offered this program reallocate time from lower intensity activities in favor of higher intensity activities when they work.

Agricultural and other physically demanding sectors are important sources of growth in developing countries but prevalent diseases such as malaria adversely impact the productivity, labor supply, and choice of job tasks among workers by reducing physical capacity. This study identifies the impact of malaria on worker earnings, labor supply, and daily productivity by randomizing the temporal order at which piece-rate workers at a large sugarcane plantation in Nigeria are offered malaria testing and treatment. The results indicate a significant and substantial intent to treat effect of the intervention-the offer of a workplace-based malaria testing and treatment program increases worker earnings by approximately 10 percent over the weeks following the offer. The study further investigates the effect of health information by contrasting program effects by workers' revealed health status. For workers who test positive for malaria, the treatment of illness increases labor supply, leading to higher earnings. For workers who test negative, and especially for those workers most likely to be surprised by the healthy diagnosis, the health information also leads to increased earnings via increased productivity. Possible mechanisms for this response include selection into higher return tasks within the plantation as a result of changes in the perceived cost of effort. A model of the worker labor decision that allows health expectations partly to determine the supply of effort suggests that, in endemic settings with poor quality health services, inaccurate health perceptions may lead workers to suboptimal labor allocation decisions. The results underline the importance of medical treatment, but also of access to improved information about one's health status, as the absence of either may lead workers to deliver lower effort in lower return jobs.

This paper studies the impact of "nudges" on taxpayers with varying tax compliance histories in Papua New Guinea. It presents the results from two population-wide randomized controlled trials in a setting that is characterized by low compliance rates and a lack of effective enforcement. The study tests the impact of text messages, flyers, and emails that remind taxpayers of declaration due dates and provide information about the public benefits of paying tax. The findings show that the treatments increased the number of tax declarations filed without increasing the amount of tax paid because the taxpayers who responded to the nudges were largely exempt from paying tax. This result is consistent across tax types, communication channels, and time periods. The findings also show that the treatments had no impact on previously non-filing taxpayers. Collectively, the results illustrate that taxpayers who face the lowest cost from complying are the most likely to respond to a nudge.
