  Partner selection is a vital feature of human behavior with important consequences for individuals, families, and society. We use the term hypergamy to describe a phenomenon whereby there is a tendency for husbands to be of higher rank within the male earnings capacity distribution than their wives are within the female distribution. Such patterns are difficult to verify empirically because earnings are both a cause and an effect of the mating process. Using parental earnings rank as a predetermined measure of earnings capacity to solve the simultaneity problem, we show that hypergamy is an important feature of today’s mating patterns in one of the most gender-equal societies in the world, namely Norway. Through its influence on household specialization, we argue that hypergamy may explain parts of the remaining gender wage gap.

  Previous studies have stressed the role of a child's family environment for future political participation. This field of research has, however, overlooked that children within the same family have different experiences depending on their birth order. First-borns spend their first years of life without having to compete over their parents' attention and resources, while their younger siblings are born into potential rivalry. We examine differences in turnout depending on birth order, using unique population-wide individual level register data from Sweden and Norway that enables precise within-family estimates. We consistently find that higher birth order entails lower turnout, and that the turnout differential with respect to birth order is stronger when turnout is lower. The link between birth order and turnout holds when we use data from four other, non-Nordic countries. This birth order effect appears to be partly mediated by socio-economic position and attitudinal predispositions.

  To what extent do early experiences in the host country shape the political integration of immigrants? We argue that the initial neighborhoods immigrants settle in establish patterns of behavior that influence subsequent political participation. Using Norwegian administrative register data, we leverage quasi‐exogenous variation in the placement of refugees to assess the consequences of assignment to particular neighborhoods. We find that the difference in turnout between refugees initially placed in 20th and 80th percentile neighborhoods is 12.6 percentage points, which represents 47% of the participation gap between refugees and residents. To assess the mechanism, we draw on individual‐level data on all neighbors present at the time of each refugee's arrival and then evaluate the relative impact of neighborhood characteristics and available social networks. Our findings suggest that while neighborhood socioeconomic factors play a limited role, early exposure to politically engaged neighbors and peer cohorts increases immigrants' turnout over the long run.

  It remains unclear if foreign direct investment (FDI) benefits local citizens in host countries. Combining geo-referenced FDI data and household level surveys, this paper uses spatial-temporal techniques to assess how FDI impacts individual corruption experiences. We investigate if this relationship is conditional on the corruption levels, or engagement with the OECD's anti-bribery convention (ABC), of the FDI's source country. We find evidence that FDI flows reduce individual bribery experiences, but only when existing levels of corruption are high. We find it is FDI from comparatively more corrupt, and non-ABC engaging, countries that locates to areas of high corruption. Further, FDI appears to improve both the employment prospects and financial positions of local households. Collectively, we argue that these results suggest that individual empowerment via a wealth effect, rather than spillovers from firm professionalization or regulatory pressure mechanisms, is what stems individual corruption experiences.

  Global climate change makes extreme precipitation events likely to become more frequent and intense in large parts of Africa. We study the effect of rainfall shocks on intimate partner violence in sub-Saharan Africa. The analysis shows the presence of spatial autocorrelation in rainfall shocks, which compromises the exogeneity of rainfall shocks in many applications. We correct for the autocorrelation using spatial polynomials. In particular, we use three different estimation strategies. We first use the complete cross-sectional sample to analyze whether recent droughts are correlated with respondents’ experience with intimate partner violence during the last year. We then use the nine countries with repeated surveys to construct a repeated cross-section analysis at the grid level. Finally, we use event history analysis on a time series constructed from the information provided by the abused women about when the violence first took place. We find no robust evidence that droughts increase intimate partner violence. Potential explanations are that the rainfall shocks do not affect spouses’ power, or that the slow onset of the droughts allows for a calmer response to the crisis. We contribute to the wider literature on climate and conflict as many of the mechanisms, economic and psychological, that link climate to violence apply to both intimate partner violence and organized violence.

  We examine whether exposure of men to women in a traditionally male-dominated environment can change attitudes about mixed-gender productivity, gender roles, and gender identity. Our context is the military in Norway, where we randomly assigned female recruits to some squads but not others during boot camp. We find that living and working with women for eight weeks causes men to have more egalitarian attitudes. There is a 14 percentage point higher fraction of men who think mixed-gender teams perform as well or better than same-gender teams, an 8 percentage point increase in men who think household work should be shared equally and a 14 percentage point increase in men who do not completely disavow feminine traits. Moreover, men exposed to mixed-gender teams are more likely to choose military occupations immediately after boot camp which have a higher fraction of females in them. But these effects do not persist once treatment stops. Treated men’s attitudes converge to those of the controls in a six-month follow-up survey and there is no long-term effect on choosing fields of study, occupations, or workplaces with a higher fraction of women in them after military service ends. Contrary to the predictions of many policymakers, we do not find that integrating women into squads hurt male recruits’ performance or satisfaction with service, either during boot camp or their subsequent military assignment. These findings provide evidence that even in a highly gender-skewed environment, gender stereotypes are malleable and can be altered by integrating members of the opposite sex. But they also suggest that without continuing intensive exposure, effects are unlikely to persist.

  While there is a vast literature studying the effects of official development aid (ODA) on economic growth, there are far fewer comparative studies addressing how aid affects health outcomes. Furthermore, while much attention has been paid to country-level effects of aid, there is a clear knowledge gap in the literature when it comes to systematic studies of aid effectiveness below the country-level. Addressing this gap, we undertake what we believe is the first systematic attempt to study how ODA affects infant mortality at the subnational level. We match new geographic aid data from the AidData on the precise location, type, and time frame of bilateral and multilateral aid projects in Nigeria with available georeferenced survey data from five Nigerian Demographic and Health Surveys. Using quasi-experimental approaches, with mother fixed-effects, we are able to control for a vast number of unobserved factors that may otherwise be spuriously correlated with both infant mortality and ODA. The results indicate very clearly that geographical proximity to active aid projects reduces infant mortality. Moreover, aid contributes to reduce systematic inter-group, or horizontal, inequalities in a setting where such differences loom large. In particular, we find that aid more effectively reduces infant mortality in less privileged groups like children of Muslim women, and children living in rural, and in Muslim-dominated areas. Finally, there is evidence that aid projects are established in areas that on average have lower infant mortality than non-aid locations, suggesting that there are biases resulting in aid not necessarily reaching those populations in greatest need.

  Combining DHS data for 580,000 women from 30 different countries in Sub-Saharan Africa, we analyze how both the incidence and the acceptance of intimate partner violence vary across time and space, in a region with record high levels of violence against women. We review the existing literature regarding the impact of resources on intimate partner violence, extracting testable and often conflicting hypotheses at the micro and macro level, and on the interaction across levels. We propose to extend existing theory to take into account attitudes at the community level. In the empirical analysis, we find no evidence that resources protect against abuse at the individual level, although resources are associated with lower acceptance. We find that resource inequality, both within the house- hold and at the aggregate level, is associated with more abuse. Finally, we find that employed women face greater risk of abuse in com- munities with relatively higher acceptance of wife-beating.

  This article explores the causal effect of personal contact with ethnic minorities on majority members’ views on immigration, immigrants’ work ethics, and support for lower social assistance benefits to immigrants than to natives. Exogenous variation in personal contact is obtained by randomising soldiers into different rooms during the basic training period for conscripts in the Norwegian Army's North Brigade. Based on contact theory of majority–minority relations, the study spells out why the army can be regarded as an ideal contextual setting for exposure to reduce negative views on minorities. The study finds a substantive effect of contact on views on immigrants’ work ethics, but small and insignificant effects on support for welfare dualism, as well as on views on whether immigration makes Norway a better place in which to live.

  We study discrimination among recruits in the Norwegian Armed Forces during boot camp. In a vignette experiment female candidates are perceived as less suited to be squad leaders than their identical male counterparts. Adding positive information leads to higher evaluations of the candidates, but does not reduce the amount of discrimination. However, randomized intense collaborative exposure to female colleagues reduces discriminatory attitudes: Male soldiers who were randomly assigned to share room and work in a squad with female soldiers during the recruit period do not discriminate in the vignette experiment.

  Høsten 2012 bevilget Stortinget 1,5 milliarder kroner over fire år til 600 nye lærerstillinger på ungdomstrinnet. Denne rapporten studerer effekter på ressursbruk, læringsutbytte og læringsmiljø, samt gir en beskrivelse av hvordan tiltaket er gjennomført og oppleves av involverte rektorer, lærere og elever. Effektevalueringen studerer skolenes ressursbruk og elevenes læringsutbytte ved hjelp av registerdata, samt læringsmiljøet målt ved Elevundersøkelsen. Vi finner en klar effekt på skolenes lærertetthet. Gjennomsnittlig gruppestørrelse i ordinær undervisning er redusert med omtrent to elever, eller omtrent 10 prosent. Dette samsvarer med hva vi venter utfra de ekstra lærerne skolene får tilført. Det er ingen tegn til effekter på assistentbruk, spesialundervisning eller særskilt språkopplæring eller til omfordeling av andre ressurser mellom skoler eller trinn. Vi finner ingen signifikante effekter på elevenes læringsutbytte, verken på karakterer ved avsluttet grunnskole, nasjonale prøver på 9. trinn, fravær eller tidlige mål på gjennomstrømning i videregående opplæring.

  This study investigates the effects of gender quotas in national elections on political participation, public policy, and corruption in Latin America. We are able to replicate the findings from previous research that women in politics do affect these outcomes, but only when we treat the number of women in parliament as exogenous. We argue, however, that the introduction of gender quotas caused an – in this context – exogenous increase in women’s representation, and while we find that quotas in Latin America increased the number of women in parliament, we find no substantial effects beyond mere representation. The mechanisms for these findings are scrutinized, and we find no indications that quota women are more marginalized than other elected women in Latin American parliaments. Hence, increasing women’s representation by means of gender quotas may not result in the same outcomes as an increased representation in non-quota elections.
