Inequality and Growth: Uncovering the Main Conclusions from the Empirics

Abstract

This paper is a critical survey of the empirical literature on the effects of inequality on economic growth. We conclude that it is most likely that the disparities found in the results are due to differences in the type of countries and time periods included in the samples, the variable used to measure inequality, the structure of the data, and the estimation techniques. These findings suggest that the mechanisms that link inequality to growth are likely to operate differently in different circumstances, an element that may offer important guidelines for both policy makers and researchers.

Agricultural Production,Dietary Diversity and Climate Variability

Abstract

Nonseparable household modelsoutline the interlinkage between agricultural production and household consumption, yet empirical extensions to investigate the effect of production on dietary diversity and diet composition are limited. While a significant literature has investigated the calorie-income elasticity abstracting from production, this paper provides an empirical application of the nonseparable household model linking the effect of exogenous variation in planting season production decisions via climate variability on household dietary diversity. Using degree days, rainfall and agricultural capital stocks as instruments, the effect of production on household dietary diversity at harvest is estimated. The empirical specifications estimate production effects on dietary diversity using both agricultural revenue and crop production diversity. Significant effects of both agricultural revenue and crop production diversity on dietary diversity are estimated. The dietary diversity-production elasticities imply that a 10 per cent increase in agricultural revenue or crop diversity result in a 1.8 per cent or 2.4 per cent increase in dietary diversity respectively. These results illustrate that agricultural income growth or increased crop diversity may not be sufficient to ensure improved dietary diversity. Increases in agricultural revenue do change diet composition. Estimates of the effect of agricultural income on share of calories by food groups indicate relatively large changes in diet composition. On average, a 10 per cent increase in agricultural revenue makes households 7.2 per cent more likely to consume vegetables, 3.5 per cent more likely to consume fish, and increases the share of tubers consumed by 5.2 per cent.     

Ecological Context,Concentrated Disadvantage,and Youth Reoffending: Identifying the Social Mechanisms in a Sample of Serious Adolescent Offenders

Serious youthful offenders are presented with a number of significant challenges when trying to make a successful transition from adolescence to adulthood. One of the biggest obstacles for these youth to overcome concerns their ability to desist from further antisocial behavior, and although an emerging body of research has documented important risk and protective factors associated with desistance, the importance of the neighborhoods within which these youth reside has been understudied. Guided by the larger neighborhood effects on crime literature, the current study examines the direct and indirect effects of concentrated disadvantage on youth reoffending among a sample of highly mobile, serious youthful offenders. We use data from Pathways to Desistance, a longitudinal study of serious youthful offenders (N = 1,354; 13.6 % female; 41.4 % African American, 33.5 % Hispanic, 20.2 % White), matched up with 2000 Census data on neighborhood conditions for youth’s main residence location during waves 7 and 8 of the study. These waves represent the time period in which youth are navigating the transition to adulthood (aged 18–22; average age = 20). We estimate structural equation models to determine direct effects of concentrated disadvantage on youth reoffending and also to examine the possible indirect effects working through individual-level mechanisms as specified by theoretical perspectives including social control (e.g., unsupervised peer activities), strain (e.g., exposure to violence), and learning (e.g., exposure to antisocial peers). Additionally, we estimate models that take into account the impact that a change in neighborhood conditions may have on the behavior of youth who move to new residences during the study period. Our results show that concentrated disadvantage is indirectly associated with youth reoffending primarily through its association with exposure to deviant peers. Taking into account youth mobility during the study period produced an additional indirect pathway by which concentrated disadvantage is associated with goal blockage (i.e., the gap between belief in conventional goals and perceived potential to reach those goals), which was then associated with exposure to deviant peers and indirectly, reoffending behavior. We conclude that the neighborhood effects literature offers a promising framework for continued research on understanding the successful transition to adulthood by serious youthful offenders.     

The Clinical Utility of Batterer Typologies

Domestic violence research has increasingly focused on the identification of batterer subgroups. Although typologies have been proposed using the utility of both empirical and theoretical methodologies, studies comparing empirically derived and theoretically based typology solutions have not been conducted. To what degree mental health practitioners can successfully classify batterers into subgroups is also not known. To address these questions, data were gathered from 49 male batterers who were treated for domestic violence in an outpatient mental health facility. A preliminary comparison of an empirically derived and a theoretically based typology solution revealed that many batterers were classified differently by the two strategies, although the overall grouping strategies were similar in content. Further, mental health professionals had substantial difficulty choosing which of the cluster analytically created subgroups into which to sort individual batterer's MMPI profile. Finally, different treatment efficacy indicators differentiated among the men in the two subtyping systems, suggesting that each system offers unique clinical information.The second author was supported as a predoctoral fellow by a NIMH Training grant     

Folktales of Legality: Family Law in the Procedural Republic The Narrative Structure of Family Law

This article explores the narrative structure offamily law where divorce is available on ground ofirretrievable breakdown following separation for oneyear. It argues that contemporary no-fault regimesexemplify law's procedural republic, a space with itsown legal, ethical and political requirements whichhas little if any connection to the life-worlds of theparties. Through an analysis of intractable parentingdisputes it argues that the interaction of no-faultdivorce, the requirement to have regard to the bestinterests of the child and the principle that childrenhave a right to contact with both parents has led tothe creation of particular narrative forms. Thesenarrative forms are characterised by their absolutismand map the unresolved grievances surrounding maritalbreakdown onto parenting disputes where the statutoryrequirements map them onto particular narratives andcounter-narratives. In this process, the narrativesof expert witnesses play an increasingly prominentrole, as do the naïve narratives put forward bylitigants in person. The article argues that thesenarratives are, in important ways, fictions and thatthey are compelled by the procedural requirements ofno-fault divorce. It argues further that thesefictions are a consequence of the empty narrative spaceat the heart of family law.     

Parenting in Battered Women: The Effects of Domestic Violence on Women and Their Children

This study integrates an ecological perspective and trauma theory in proposing a model of the effects of domestic violence on women's parenting and children's adjustment. One hundred and twenty women and their children between the ages of 7 and 12 participated. Results supported an ecological model of the impact of domestic violence on women and children. The model predicted 40% of the variance in children's adjustment, 8% of parenting style, 43% of maternal psychological functioning, and 23% of marital satisfaction, using environmental factors such as social support, negative life events, and maternal history of child abuse. Overall, results support the ecological framework and trauma theory in understanding the effects of domestic violence on women and children. Rather than focusing on internal pathology, behavior is seen to exist on a continuum influenced heavily by the context in which the person is developing.
