Why do women engage in transactional sex? While much of the explanation is that sex-for-money pays more than other jobs, this paper uses a unique panel dataset constructed from 192 self-reported diaries of sex workers in Western Kenya to show that women who supply transactional sex develop relationships with regular clients, and that these clients send transfers in response to negative income shocks. Regular clients are the primary source of inter-person insurance that women receive, and women report in a separate survey that client transfers are an important reason that they participate in the market.

Croatia began to implement case-based provider payment reforms in hospitals beginning in 2002, starting with broad-based categories according to therapeutic procedures. In 2009, formal diagnostic related groups were introduced, known locally as dijagnosticko terapijske skupine. This study examines the efficiency and quality impacts of these provider payment reforms globally on the Croatian health system by analyzing data on five procedures in acute health care for 10 years, between January 2000 and December 2009. The five procedures are cataracts, pneumonia, coronary bypass, appendectomy, and hip replacement. Using data from the Croatian Institute for Health Insurance, this study finds that both broad-based and detailed case-based payment systems have improved efficiency as measured by a reduction in average length of stay, with little impact on the number of cases. These provider payment reforms have had no adverse impact on quality as measured by readmissions. While it is still too early to quantify the impact of Croatia's introduction of formal diagnostic related groups, it appears that the introduction of both broad and detailed case-based payment systems has improved efficiency in acute hospital care.

We use survey data on an opt-in panel of around 2,500 US small businesses to assess the impact of COVID-19. We find a significant negative sales impact that peaked in Quarter 2 of 2020, with an average loss of 29% in sales. The large negative impact masks significant heterogeneity, with over 40% of firms reporting zero or a positive impact, while almost a quarter report losses of more than 50%. These impacts also appear to be persistent, with firms reporting the largest sales drops in mid-2020 still forecasting large sales losses a year later in mid-2021. In terms of business types, we find that the smallest offline firms experienced sales drops of over 40% compared to less than 10% for the largest online firms. Finally, in terms of owners, we find female and black owners reported significantly larger drops in sales. Owners with a humanities degree also experienced far larger losses, while those with a STEM degree saw the least impact.
