Unfair treatment, neighborhood effects, and mental health in the Detroit metropolitan area

Why do racial differences in many indicators of mental and emotional well-being show inconsistent patterns? We propose that mental and emotional well-being are influenced by aspects of the social context, including experiences of unfair treatment and the concentration of households with incomes below the poverty level, and that differential exposure to these factors influences racial differences in mental well-being. We analyze the reporting of psychological distress and life satisfaction in a multistage area probability sample of 1,139 African American and white residents of the Detroit metropolitan area aged 18 and older. Both psychological distress and life satisfaction are significantly associated with exposure to unfair treatment and with the proportion of households in the census block group that were below the poverty level. Racial differences in psychological distress and life satisfaction were eliminated or reversed once differentials in the percent of households living below the poverty line and exposure to unfair treatment were accounted for. These findings contribute to a growing body of evidence that "race" effects operate through multiple pathways that include race-based residential segregation and its attendant economic disinvestment at the community level, and interpersonal experiences of unfair treatment.     

Fertility and the economy

I relate the demand for children to parental incomes and the cost of rearing children — especially to the value of the time spent on child care and to public policies that change the cost of children. This paper also links the demand for children to investments in their human capital and other dimensions of the so-called quality of children. Fertility is shown to depend too on child and adult mortality, uncertainty about the sex of children — if there is a preference for boys, girls, or for variety — uncertainty about how long it takes to produce a conception, and other variables.Since biological necessity dictates that succeeding generations overlap, it is not surprising that fertility in one generation influences the fertility of succeeding generations. The overlapping generations approach provides a useful framework for relating fertility choices to population growth and macroeconomic changes.The modern approach to fertility leads to very different interactions between population growth and economic growth than is implied either by Malthusian or the usual neo-classical growth models. In particular, it provides a framework for analyzing how societies escape a Malthusian-like stagnating equilibrium and embark on the journey toward becoming modern economies, where per capita incomes, human capital, and physical capital all continue to grow, fertility declines to rather low levels, and married women participate extensively in the labor force.This essay was prepared for the Nobel Jubilee Symposium, Lund, Sweden, December 5–7, 1991. I have had valuable comments from James Heckman, Robert Willis and my discussants at the symposium: Allesandro Cigno and Richard Easterlin, and useful assistance from Becky Kilburn.

Changing Business Models and Employee Representation in the Airline Industry: A Comparison of British Airways and Deutsche Lufthansa

In recent years, the notion of business models has gained momentum in management research. Scholars have discussed several barriers to changing business models in established firms. However, the national institutions of market economies have not yet been discussed as barriers, even though they can constrain the latitude of action of a firm's management. Based on interviews and a longitudinal content analysis, we analyse the extent to which full service carriers in two countries (British Airways in the UK and Deutsche Lufthansa in Germany) have adopted elements of a low cost model over time. Furthermore, we investigate how this process has been influenced by the differences in each national institutional context. We particularly focus on the role of the rights of employee representatives in changes in business models. Our results show that British Airways has moved its business model more in the direction of low cost carriers than Deutsche Lufthansa, although the business model of the former airline still differs significantly from that of a typical low cost carrier. We identify national institutions that potentially strengthen the position of employee representatives as a factor that can influence, and also act as a barrier to, business model change.     

The longitudinal link between popularity,likeability, fear of negative evaluation and social avoidance across adolescence

This study investigated the longitudinal bidirectional associations between likeability, popularity, fear of negative evaluation, and social avoidance, to aid in preventing the negative consequences and persistent trajectories of low social status and heightened social anxiety. In total, 1741 adolescents in grades 7–9 participated at 3 yearly waves. A self-report questionnaire measured fear of negative evaluation. Peer nominations assessed likeability, popularity, and social avoidance. Lower popularity predicted more avoidance, and vice versa. More avoidance was related to lower likeability over time. Being less popular and/or more liked by peers, increased fear of negative evaluation. Support for a transactional model between social anxiety and social status was found, but distinguishing different social status and social anxiety components is necessary.     

Communicating social value: An experimental study on credible communication and social enterprises

The management of marketing and communication strategies involves a complex mix of different requirements, particularly for social enterprises, which try to fulfill both social and business aims while operating in a resource-constrained context. Although social enterprises are a rising phenomenon, the research on how these businesses communicate their activities remains in its infancy. This study builds on the theory of planned behavior and the source credibility theory, presenting a conceptual framework that distinguishes between high, moderate, and low credibility of a social enterprise's communication, to analyze its effects on potential customers' behavioral intentions. Through an online experiment with 260 subjects, the authors demonstrate that attitude toward a social enterprise, subjective norm, perceived behavioral control, and, ultimately, the intention to support a social enterprise by purchasing its products increases with the social enterprise's message credibility. The authors also present practical implications and avenues for future research on the communication of social enterprises based on the empirical findings.
