Risk aversion and equilibrium selection in a vertical contracting setting: an experiment

Theory and Decision - The theoretical literature on vertical relationships usually assumes that beliefs about secret contracts take specific forms. In a recent paper, Eguia et al. (Games Econ Behav...     

Influence of a Community Health Worker Intervention on Mental Health Outcomes among Low-Income Latino and African American Adults with Type 2 Diabetes

This study investigated the influence of a community health worker (CHW) diabetes lifestyle intervention on mental health outcomes. Our study was guided by the principles of community-based participatory research. Data were collected from 164 African American (N = 94) and Hispanic adults (N = 70) participating in a randomized, 6-month delayed intervention group design for improving glycemic control. The intervention time periods were baseline to 6 months for the treatment group and 6–12 months for the delayed group. Linear mixed models were used to conduct longitudinal analyses of the Problem Areas in Diabetes (PAID) and Patient Health Questionnaire (PHQ) scales. In the model adjusted for demographics, the PAID dropped significantly from pre-intervention to post-intervention within both the treatment and delayed groups (p < 0.05) with an average intervention effect of ?6.4 (p < 0.01). The PAID dropped even further within the immediate group from 6 to 12 months. Although the PHQ did not change significantly, the PHQ-2 had an average intervention effect of ?0.3 (p < 0.05) in the model adjusted for demographics. This study contributes to an understanding of how a CHW-led diabetes intervention can result in positive mental health outcomes for Latinos and African Americans with Type 2 diabetes. It also highlights the importance of further exploring what factors may contribute to racial/ethnic variation in mental health outcomes for African Americans and Latinos with diabetes and the role CHWs can play.     

Weather and Smiling Contagion: A Quasi Experiment with the Smiling Sunshine

Studies have shown that pleasant weather conditions (namely, sunshine) favor positive social relationships and improve moods. However, the effect of sunshine on one nonverbal expression that facilitates social relationships (namely, smiling) has never been studied. In a field experiment, men and women walking alone in the street were passed by a male or a female confederate who displayed a smile to the passersby. The contagion effect of smiling was measured. The study was carried out on days that were evaluated as being either sunny or cloudy, but precaution was taken to control the temperature and not to solicit participants when it rained. It was found that the display of a smile results in a smile more often on sunny days. The positive mood induced by the sun may explain such results.     

The Future Composition of the Canadian Labor Force: A Microsimulation Projection

This article charts the future transformations of the Canadian labor force population using a microsimulation projection model. The model takes into account differentials in demographic behavior and labor force participation of individuals according to their ethnocultural and educational characteristics. As a result of a rapid fall in fertility, the Canadian population is expected to age rapidly as baby boomers start to retire from the labor market in large numbers. In response to declining fertility, Canada raised its immigration intake at the end of the 1980s, and immigration is now the main driver of Canadian population growth. At the same time, immigrants to Canada are becoming more culturally diversified. Over the last half century, the main source regions have shifted from Europe to Asia. Results of the microsimulation show that Canada's labor force population will continue to increase, but at a slower rate than in the recent past. By 2031, almost one third of the country's total labor force could be foreign‐born, and almost all its future increase is expected to be among university graduates, while the less‐educated labor force is projected to decline.     

Vulnerability to violence of girls of the street in Mauritania

This article is concerned with an empirical study of girls of the street in Mauritania. This study is original for three main reasons. First, it investigates Mauritania, a country where there have been very few studies of the phenomenon of children of the street. Secondly, it seems to us that though the academic literature on street children sometimes provides comparisons between girls and boys, very few studies focus specifically on girls of the street. Thirdly, the literature focusing on children of the street generally elucidates the mechanisms that lead some young people to live on the streets. On the contrary to previous literature, our study does not directly focus on mechanisms that lead some young people to live on the streets. Our study focuses on the question of the socio-economic determinants of the risk of violence. In other words, whereas the literature, following the hypothesis of aberrant families, uses violence as an explanatory factor for the phenomenon of children of the street, we attempt here to highlight the explanatory factors for the risk of violence and we treat this risk as an explained variable. A novel finding emerges from this study: there is less risk of violence facing girls of the street if the mother does not work. Conversely, the risk of violence is greater if the mother works and the father stays at home.
