Linearization of inequality indices in the design-based framework

Linearization methods are customarily adopted in sampling surveys to obtain approximated variance formulae for estimators of statistical functionals under the design-based approach. In the present paper, following the Deville [Variance estimation for complex statistics and estimators: linearization and residual techniques. Surv Methodol. 1999;25:193–203] approach stemming from the concept of design-based influence function, we provide a general result for linearizing a large family of population functionals which includes many of the inequality measures considered in social, economic and statistical studies, such as the Gini, Amato, Zenga, Atkinson and Generalized Entropy indices. The feasibility of our theoretical results is assessed by some simulation studies involving real and artificial data.     

Falling short of the promise: poverty vulnerability in the United States and Britain, 1993-2003

The welfare state promises to moderate the duration and concentration of poverty. The authors ask how well this promise has been fulfilled in the United States and Britain from 1993 to 2003. They examine two aspects of poverty vulnerability during this period of welfare reform: (1) its persistence and associated risk factors and (2) the efficacy of social transfers. After accounting for measurement error, sociodemographic characteristics, and the impact of redistributive programs, the authors find that poverty is often persistent and risk is concentrated, especially in the United States. Moreover, the British safety net appears to better protect those at risk.     

Peers’ emotionality and children's academic achievement in second grade: Testing the moderating role of children's behavioral self-regulation

Although there is interest in the role of peers in children's schooling experiences, few researchers have examined associations and related underlying processes between peers’ emotionality, an aspect of temperament, and children's academic achievement. This study evaluated whether target children's (N = 260) own self-regulation, assessed with two behavioral measures, served a moderating function for associations between peers’ emotionality and children's own academic achievement in second grade. There was a positive association between peers’ positive emotionality and reading scores for children with higher self-regulation. Peers’ negative emotionality was negatively related to target children's reading scores, particularly for children with higher self-regulation levels, but was unrelated to math scores. Peers’ positive and negative emotionality did not predict math scores, and there was no strong evidence for the moderating role of target children's self-regulation in this association. This study highlights the potential role of children's self-regulation in modulating peer effects on academic achievement, particularly reading.     

Race,Wealth and the Masking of Opposition to Immigrants in the Netherlands

This work uses a list experiment to directly test for differences in attitudes towards poor, racially different and racially similar immigrants to the Netherlands in terms of (1) overt support and (2) covert support and (3) the difference between the two (i.e., social desirability bias). Results show that the expression of opposition to immigrants is significantly masked, suggesting that anonymous acts (e.g., voting) could capture greater opposition. Racially similar immigrants are subject to greater opposition relative to racially different or poorer immigrants, but only when anonymity is offered to respondents. The implication is that overt estimates (i.e., openly expressed) are misleading as levels of support appear consistent across immigrant groups. Going forward, we suggest the utility of the list experiment to better account for observable downward bias in estimates at least on the aggregate level or in contexts with clear normative pressure to appear tolerant.     

A contradiction in terms? migrant activists in the Sweden Democrats party

Right-wing, xenophobic and racist parties have enjoyed immense successes in Europe in recent decades. In Sweden, the third-largest party in Parliament is the Sweden Democrats (SD), with 13% in the 2014 general election. Sympathy for the SD among foreign-born Swedish citizens, both women and men, is far lower than among Sweden-born men, but an increasing number of Swedish citizens with migrant backgrounds support the party. The aim of this article is to explore the subject positions open for citizens with migrant background in the Swedish public space with special focus on the identities and worldviews developed by migrant activists who have joined the SD party and are, to differing degrees, racialised and perceived as non-Swedish. Using the concept of migrant respectability, this research is intended to understand why and under what circumstances migrants chose to join and represent a xenophobic and racist party.     

The effects of international diversification on the link between product diversification and performance in a boom and bust cycle: Evidence from Spanish firms (1994–2014)

This study examines the individual effects of product diversification on performance and the moderating effects of international diversification on the product diversification–performance link in the context of a boom and bust cycle. Most prior research on firm strategies largely neglect the business cycle. We use data on a large sample of Spanish manufacturing firms from 1994 to 2014. In this period, the Spanish economy experienced a boom period (1994–2008) and a bust period involving a severe economic crisis (2009–2014). Our study highlights the important role of each stage of the economic cycle. Specifically, with respect to product diversification, our findings show that in a boom, moderate diversifiers obtain better profitability levels than their highly diverse or limited diversification counterparts do. In contrast, during an economic downturn, moderate and high diversifiers can be equally effective up to some point of optimization. Our findings also reveal a negative and significant effect of internationalization on profitability, independent of the stage of the economic cycle. Product and international diversification are complementary strategies during a period of economic growth when firms opt for moderate levels of product diversification. Meanwhile, when firms choose high levels of product diversification, both types of strategies are complementary during the boom cycle, but substitutive during the bust cycle.     

Mapping Colombian Citizens’ Views Regarding Ordinary Corruption: Threat,Bribery, and the Illicit Sharing of Confidential Information

A few studies conducted in France, Latin America, China and Sub-Saharan Africa have examined the extent to which specific behaviors by politicians, state officials, professionals or simple citizens were considered by the public either as corrupt/intolerable or acceptable/tolerable. These studies have shown a great diversity of positions among participants, ranging from “zero tolerability” to “non-zero tolerability”, to high tolerance to favoritism, and to complete tolerability. The present study analyzed Colombian lay persons’ views as a function of three separate factors characterizing acts of corruption: (a) the current status or position in society of the person who behaved in a corrupt way (politician, judge, entrepreneur or ordinary citizen), (b) the motive behind the act of corruption (nepotism or monetary gain), and (c) the means used for obtaining the underserved benefit (threatening the person, bribery or illicitly sharing of confidential information). As expected, four qualitatively different perspectives were identified. The first one (60 % of the participants) was the expected Zero Tolerance view because all acceptability ratings were extremely low. The second one (32 %) was called Never Very Tolerable because ratings, although always low, varied as a function of the means used: Threat and bribery were considered as more intolerable than use of information. The third one (7 %) was called Depends on Means because the ratings were affected by the means used to a larger extent than in the preceding case. The fourth one (1 %) was called Always Tolerable because in all cases, the ratings were high. In no cases did acceptability depend much on the status of the person performing the corrupt act or of the motives behind the act. Although only a small minority of participants agreed with the last two views, it is probably enough to create a climate of suspicion in the country.     

The Impact of Welfare Reform Policies on Child Protective Services: A National Study

The 1996 welfare reform bill set forth major changes in social welfare policies. In addition to federal work requirements and time limits, new state policies impose behavioral mandates that may be accompanied by financial sanctions for noncompliance. Analysis of a survey of state Child Protection Services (CPS) directors focuses on four major areas: effect of Temporary Assistance to Needy Families (TANF) on CPS; interaction between the two agencies; role of TANF sanctions in referrals to CPS; and select special areas of concern. This research provides empirical insight into the interaction between these two agencies, specific TANF sanctions, and the potential conflicts between TANF policies and CPS concerns for the welfare of children and families under its charge.
