Information Frictions in Trade

It is costly to learn about market conditions elsewhere, especially in developing countries. This paper examines how such information frictions affect trade. Using data on regional agricultural trade in the Philippines, I first document a number of observed patterns in trade flows and prices that suggest the presence of information frictions. I then incorporate information frictions into a perfect competition trade model by embedding a process whereby heterogeneous producers engage in a costly sequential search process to determine where to sell their produce. I show that introducing information frictions reconciles the theory with the observed patterns in the data. Structural estimation of the model finds that information frictions are quantitatively important: roughly half the observed regional price dispersion is due to information frictions. Furthermore, incorporating information frictions improves the out‐of‐sample predictive power of the model.     

From Freud to Feminism: Gendered Constructions of Blame Across Theories of Child Sexual Abuse

Most theories of child sexual abuse are, to some degree, gendered, with nonoffending mothers bearing the burden of blame, ideologically and legally, for the transgressions of predominantly male offenders. This article explores the social construction of blame for child sexual abuse via critical analyses of evolving theoretical perspectives on maternal culpability for the inception and maintenance of abuse dynamics. Drawing on selected conceptual and research knowledge that supports and refutes anecdotal claims, this synthesis of the literature culminates in the proposal of an evidence-informed, feminist-grounded, multitheoretical child sexual abuse framework that disrupts dominant mother-blaming discourse and guides socially just and ethically responsive policy, practice, and research.     

Infants born full term and preterm increase the height of anti-gravity leg movements during a kick-activated mobile task using a scaffolded task environment

Prior research supports that infants born very preterm (PT), compared with full term (FT), have early differences in rate of learning and motor control that may hinder their ability to learn challenging motor tasks. Four-month-old infants born FT (n = 18) and PT (n = 18) participated in an infant kick-activated mobile task that was scaffolded to motivate progressively higher kicks. We found the FT group learned the association between their leg movements and mobile activation on the second day, but the PT group learned the association on the third day. Both groups of infants increased the height of their kicks on the day they learned the task, compared with their spontaneous kicking height. These findings suggest that infants born PT have the ability to learn challenging motor tasks, such as kicking high, when participating in a task environment that uses scaffolding.

Perceived discrimination and health: Paradigms and prospects

This article reviews recent research on the effects of perceived discrimination on subsequent mental and physical health. I argue that despite legal reforms banning discrimination since the civil rights era, discrimination persists, posing an ongoing health risk and maintaining social health inequalities. Couched within broader health trends, this covers ongoing challenges and new developments, particularly related to measurement, and promising directions. As the most commonly reported location of individual discrimination is at work, this review concludes by arguing for the significance of the workplace as a unique context ripe for further inquiry for scholars interested in health inequality.     

Social Networking Site Use Predicts Changes in Young Adults’ Psychological Adjustment

This study examined youths’ friendships and posted pictures on social networking sites as predictors of changes in their adjustment over time. Observational, self‐report, and peer‐report data were obtained from a community sample of 89 young adults interviewed at age 21 and again at age 22. Findings were consistent with a leveling effect for online friendships, predicting decreases in internalizing symptoms for youth with lower initial levels of social acceptance, but increases in symptoms for youth with higher initial levels over the following year. Across the entire sample, deviant behavior in posted photos predicted increases in young adults’ problematic alcohol use over time. The importance of considering the interplay between online and offline social factors for predicting adjustment is discussed.     

Fighting Fair: Adaptive Marital Conflict Strategies as Predictors of Future Adolescent Peer and Romantic Relationship Quality

This study examined the associations between reasoning during inter‐parental conflict and autonomous adolescent conflict negotiation with peers over time. Participants included 133 adolescents and their parents, peers, and romantic partners in a multi‐method, multiple reporter, longitudinal study. Inter‐parental reasoning at adolescent age of 13 predicted greater autonomy and relatedness in observed adolescent–peer conflict one year later and lower levels of autonomy undermining during observed romantic partner conflict five years later. Inter‐parental reasoning also predicted greater satisfaction and affection in adolescent romantic relationships seven years later. Findings suggest that autonomy‐promoting behaviors exhibited in the inter‐parental context may influence adolescents' own more autonomous approaches to subsequent peer and romantic conflict. Possible explanatory models are discussed, including social learning theory and attachment theory.
