Small firms struggle to grow beyond a few employees. We introduce monitoring devices into commuter minibuses in Kenya and randomize which minibus owners have access to the data using a novel mobile app. We find that treated vehicle owners modify the terms of the contract to induce higher effort and lower risk taking from their drivers. This reduces firm costs and increases firm profitability. There is suggestive evidence that some firms expand. These results suggest that small firms may be able to utilize monitoring technologies to overcome problems of moral hazard and enhance their profitability.

The Women, Peace, and Security (WPS) sector assumes increasing the number of women involved in peace negotiations drives better outcomes for local women. However, empirical support for this assumption is inconsistent. This article tests how power alters the relationship between women’s formal (Track 1) involvement in peace negotiations and the inclusion of women-specific provisions in peace agreements. Using an original dataset comprised of 2,299 Track 1 delegates involved in 116 comprehensive peace agreements finalized between 1990 and 2021, I find women’s involvement in peace negotiations is positively correlated to comprehensive agreements containing provisions for women. However, this correlation is dependent on women holding positions of power—simply having women in the room is insufficient. This article offers a novel quantitative approach to WPS studies, provides nuance to theories linking descriptive and substantive representation, and casts doubt on the longstanding assumption that increasing women’s involvement inherently enhances gender equality.

Recent religious declines in the United States are for a large part driven by the growing number of Americans who were raised religiously but left religion in the transition to adulthood. Nonetheless, their views and behaviors may still be influenced by their religious upbringing. We explore such legacy effects by examining how changing religiosity during the transition to adulthood influences volunteering among young adults. Analyzing panel data from the National Study of Youth and Religion, we estimate two types of effects: effects of cumulative religious trajectories in youth, and effects of religiosity in youth that are not mediated by religiosity in adulthood. We find that histories of religious involvement shape volunteering in adulthood, but the precise nature of such effects varies across dimensions of religiosity and types of volunteering. Religious service attendance in youth promotes volunteering in adulthood mostly indirectly, through influencing religiosity in adulthood, and exclusively for activities organized by religious groups. By contrast, religious identification in youth promotes volunteering in adulthood also through other channels, and its effects on secular volunteering may persist even when people are not religious in adulthood. We discuss the implications of these findings in light of ongoing declines in religiosity in the United States.

Countries officially record the number of COVID-19 cases based on medical tests of a subset of the population. These case count data obviously suffer from participation bias, and for prevalence estimation, these data are typically discarded in favor of infection surveys, or possibly also completed with auxiliary information. One exception is the series of infection surveys recorded by the Statistics Austria Federal Institute to study the prevalence of COVID-19 in Austria in April, May, and November 2020. In these infection surveys, participants were additionally asked if they were simultaneously recorded as COVID-19 positive in the case count data. In this article, we analyze the benefits of properly combining the outcomes from the infection survey with the case count data, to analyze the prevalence of COVID-19 in Austria in 2020, from which the case ascertainment rate can be deduced. The results show that our approach leads to a significant efficiency gain. Indeed, considerably smaller infection survey samples suffice to obtain the same level of estimation accuracy. Our estimation method can also handle measurement errors due to the sensitivity and specificity of medical testing devices and to the nonrandom sample weighting scheme of the infection survey. The proposed estimators and associated confidence intervals are implemented in the companion open source R package pempi available on the Comprehensive R Archive Network (CRAN).

This article focuses on the discursive and practical strategies of German humanitarian work on behalf of Ottoman Armenians in the Eastern Mediterranean beginning in the 1890s. Unlike their British, French, and US counterparts, German humanitarians, restrained by their government’s pro-Ottoman politics, relied on mobilization and funding strategies that catered to an evangelical moral counterpublic. Pious journalism and educational efforts focused on individual stories and suffering and catered to both popular reading preferences and a devout audience, generating particular humanitarian fantasies, namely the pursuit of salvation through the rescue of distant others. These fantasies provided the raw material for the construction of an imagined humanitarian community solidified by an individualized one-to-one child sponsorship system involving the circulation of letters, photographs, blessings, moral instructions, and money. The donations of this pious Protestant counterpublic enabled the establishment of an enduring humanitarian project with the hallmarks of modern humanitarianism; it was international, bureaucratic, and perceived as permanent. The largely neglected German humanitarian efforts reveal the continuities between a post–World War I secular, permanent, institutionalized, solution-oriented humanitarian regime and the religious, supposedly “sporadic” missionary humanitarianism of the 19th century, as its established practices carried over into and inspired the work of the interwar period.

Research indicated an association of acute and chronic physical activity with creative ideation performance. However, no study to date applied ecologically valid ambulatory methods with the potential to generalize these positive relationships to everyday life contexts. This study assessed acute and chronic physical activity (i.e., number of steps assessed via acceleration sensors) as well as creative ideation performance (in the verbal and figural domain) with an ecological momentary assessment approach in a sample of 157 young adults. We found that both single bouts of walking and walking regularly were associated with more original verbal ideas. Positive affect did not mediate this association; however, for figural creativity, the indirect path of acute physical activity via acute positive affect was significant. Although the relationship between walking and creativity seems to be domain-specific, the study findings suggest that the positive effects of physical activity on creativity transfer to everyday life contexts.
