Immigrant mothers’ preferences for children’s sexes: A register-based study of fertility behaviour in Norway

Parental sex preferences have been documented in many native populations, but much less evidence is available on immigrants’ preferences for the sexes of their children. Using high-quality longitudinal register data from Norway, a country with a recent immigration history, we estimate hazards regression models of third birth risks by the sex composition of the first two children. A central question in the extant literature is whether the sex preferences of immigrant mothers match those observed in their country of origin, or if cultural adaption to local conditions is more important. Our analyses indicate that the sex preferences of immigrants generally match those previously documented for their native population, especially in the case of son preferences. The pattern of sex preferences is unmodified by the mother’s exposure to the host society. In sum, our evidence generally supports theories emphasizing cultural persistence in preferences, rather than theories of adaption or immigrant selectivity.     

Dissolution risks in first and higher order marital and cohabiting unions

More and more people enter multiple unions during their lives, and then they may choose to either cohabit or marry. We examine the implications of this diversity in partnership trajectories by assessing dissolution risks in first and higher order marital and cohabiting unions. We use recent Norwegian survey data that contain complete retrospective union histories. We find that, when selectivity is accounted for, higher-order unions are not less stable than first unions. When dissolution risks for all possible partnership trajectories are compared, we find that former cohabitants who cohabit in a second union are as likely to break up as they were in their first cohabiting union. As soon as they enter marriage in their second unions, however, they do slightly better than first married persons. The previously married experience higher dissolution risks in their second union compared to their first, regardless of their current union type.     

THE CONSEQUENCES OF (DE)REGULATION ON EMPLOYMENT DURATION AND EFFICIENCY: AN EXPERIMENTAL STUDY

If the future market wage is uncertain, engaging in long‐term employment is risky, with the risk depending on how regulated the labor market is. In our experiment long‐term employment can result either from offering long‐term contracts or from repeatedly and mutually opting for rematching. Treatments differ in how regulations restrict the employer's flexibility in adapting the employment contract. All treatments allow for longer contract duration as well as for mutually opting to be rematched. Effort is chosen by employees after a contract is concluded. Treatments vary from no contract flexibility to no restriction at all. Will more (downward) flexibility be used in ongoing employment but reduce labor market efficiency? And will regulation crowd out long‐term employment, in the form of long‐term contracts or voluntary rematching? (JEL C72, C90, F16, J21, J24, L10)     

Does Community Context Have an Important Impact on Divorce Risk? A Fixed-Effects Study of Twenty Norwegian First-Marriage Cohorts

The decision to divorce may be affected by the characteristics of the local community. Community characteristics may be barriers to divorce, or they may increase the attractiveness of divorcing (e.g., access to a good remarriage market), but our knowledge of such influences is sparse. This study examines two such community-level factors: socio-economic conditions and the local marriage market. In this study, discrete-time hazard models with community-level fixed effects are estimated using register-based data on Norwegian first marriages during the period from 1980 to 1999, with longitudinal information on both the community and couple levels (N?=?283,493). The results show that there are important community-level influences on couples?? divorce risk, but these change dramatically when fixed effects are introduced.     

Intelligence and family size

This paper describes the results obtained in administering a modified Terman intelligence test to 327 Greek children aged from 7 to 12 years. A negative correlation between intelligence and family size was obtained. The results are compared with those obtained in similar inquiries in Britain and the U.S.A.     

SATISFICING AND PRIOR‐FREE OPTIMALITY IN PRICE COMPETITION

We apply a model of satisficing to oligopoly markets with price competition. Sellers have profit aspirations reflecting their conjectures about their competitors' behavior and search for a price guaranteeing these aspirations. Because it seems implausible that people have detailed priors on the others' actions, we postulate that sellers entertain multiple conjectures to which no probabilities can be assigned. This allows us to propose a theory of “prior‐free” optimality and to examine experimentally whether people comply with it. We find that decision makers have difficulties in making prior‐free optimal choices. Most are content to just satisfice, although ways to aspire to more ambitious profits were obviously available.
