Siblings in lockdown: International evidence for birth order effects on child adjustment in the Covid19 pandemic

Supportive family relationships may mitigate the impact of the Covid19 pandemic on young children's adjustment, but existing work is limited by its focus on within-country variation and parental influences. Addressing these gaps, and drawing on reported buffering effects of older siblings on child mental health (Lawson and Mace, 2010), the current international study examined whether child adjustment problems were, on average, elevated by the pandemic and whether this buffering effect of older siblings would be maintained. In the first wave of the Covid19 pandemic (April to July 2020), 2516 parents of 3- to 8-year-old children living in Australia, China, Italy, Sweden, United Kingdom, and United States of America—six countries with contrasting governmental responses to the pandemic—completed an online survey about family experiences and relationships and child adjustment, as indexed by ratings on the Strengths and Difficulties Questionnaire (SDQ: R. Goodman, 1997). As expected, child SDQ total difficulty scores were elevated in all sites except Sweden (which notably did not enforce mass school closures). Compared to children without siblings, children with one or more older siblings showed fewer adjustment problems. Children from lone-parent households displayed more adjustment problems, as did those whose parents reported increased sibling conflict. Finally, child adjustment problems were negatively associated with family socio-economic status, but positively related to the indices of Covid-19 family disruption and government stringency. We discuss these findings in relation to existing work on asymmetric effects of older versus younger siblings, and siblings as sources of support.     

Public Disclosure and Dissimulation of Insider Trades

Regulation requiring insiders to publicly disclose their stock trades after the fact complicates the trading decisions of informed, rent‐seeking insiders. Given this requirement, we present an insider's equilibrium trading strategy in a multiperiod rational expectations framework. Relative to Kyle (1985), price discovery is accelerated and insider profits are lower. The strategy balances immediate profits from informed trades against the reduction in future profits following trade disclosure and, hence, revelation of some of the insider's information. Our results offer a novel rationale for contrarian trading: dissimulation, a phenomenon distinct from manipulation, may underlie insiders' trading decisions.     

Racial Attitudes in the Deep South: Persistence and Change at the University of Alabama, 1963–2013*

Using data from a unique series of surveys collected between 1963 and 2013, this study examines racial attitudes among young white adults in the Deep South over a 50-year period. Repeated surveys of University of Alabama students in 1963, 1966, 1969, 1972, 1983, 1988, and 2013 measured racial stereotypes, support for racial segregation, and in the 2013 study, racial resentment and support for ameliorative racial policies. Analyses show that in the 1960s endorsement of racial stereotypes was a powerful predictor of support for racial segregation. By the early 1970s, racial integration became a reality in the Deep South and, paralleling broad trends in U.S. society, endorsement of racial stereotypes and support for racial segregation declined. Simultaneously, threats to whites' position in the form of ameliorative racial policies (including affirmative action) emerged along with racial resentment. By 2013, racial resentment, rather than racial stereotyping, was the primary determinant of white students' opposition to racial change. Our findings support Herbert Blumer's (1958) argument that racial prejudice exists in a sense of group position, and that it functions to preserve the advantaged position of the dominant group regardless of changes in the form that prejudice takes.
