Living in Fear: The Dynamics of Extortion in Mexico’s Drug War
Using new survey data from Mexico, including list experiments to elicit responses about potentially illegal behavior, this article measures the prevalence of extortion and assistance among drug trafficking organizations.
This paper examines how power lawyers shape judicial and economic outcomes by studying the “revolving door” between judges and lawyers in China’s judicial system—namely, former judges who quit the bench to practice law. In otherwise identical lawsuits, revolving-door lawyers deliver 8−23% higher win rate for their clients. Their performance in home versus away courts suggests these gains stem from both “know how” and “know who.” We extend the theoretical framework of Dewatripont and Tirole (1999) to show that revolving-door lawyers create countervailing forces in society: they enhance judicial decision-making through evidence and reasoning, but also exploit strategic arguments and connections to bias outcomes in favor of their clients. We estimate a structural model of the judicial process to quantify these trade-offs and find that increasing the supply of power lawyers can have a non-monotonic effect on equilibrium judicial quality.
Policy experiments are crucial for fostering innovation and mitigating risks and can serve as catalysts for transformative changes. This study investigates the governance of policy experiments in China, focusing on how political factors shape their outcomes. It emphasizes the need to consider concurrent trials—related policy trials implemented simultaneously in a locality that can influence outcomes—when selecting comparable cases for analysis. Such consideration is critical, especially when the policy issue spans multiple sectors and the level of difficulty differs across sectors. By comparing five cities engaged in the same three decarbonization pilots between 2010 and 2015, Hangzhou and Xiamen are identified to have had similar initial conditions and goals but achieved divergent outcomes. This research uncovers the critical role of political leadership in achieving varying levels of decarbonization progress and identifies policy coherence with broader local priorities to be the key explanation for continued leadership attention and efforts devoted to decarbonization despite turnover. The study contributes to the literature by addressing the under-studied impact of political factors and concurrent trials, offering a replicable procedure for future research and practical policy applications.
The effects of psychological factors on complementary feeding behavior have been widely described, yet the mechanisms underlying the complex relationships among personality traits, self-efficacy, and complementary feeding behavior remain unclear. This cross-sectional study was conducted using a multi-stage cluster sampling process to select caregiver-child dyads in Western rural China. Personality traits, self-efficacy, and complementary feeding behavior were evaluated respectively. Both multiple logistic regression and Bayesian network structure (BNs) were used to explore these associations. A total of 787 caregiver-child dyads were enrolled. Results from multiple logistic regression indicated that caregivers with medium (OR = 2.05, p < 0.001) or high (OR = 1.58, p = 0.04) levels of extraversion, as well as those with high self-efficacy recording complementary feeding (OR = 2.08, p < 0.001), significantly increased the likelihood of meeting the criteria for the Infant and Child Feeding Index (ICFI) qualification. Further, BNs were employed to elucidate the pathways of influence, revealing a direct association between the caregiver's level of extraversion, level of self-efficacy and the ICFI. Additionally, the analysis indicated that a caregiver's openness indirectly influenced the ICFI through its influence on self-efficacy regarding complementary feeding. This is one of few studies exploring associations between personality traits, self-efficacy, and complementary feeding behavior. The study highlights the importance of understanding individual differences in caregiving and suggests that interventions should focus on enhancing caregivers' self-efficacy, rather than solely targeting personality traits.
This paper examines whether education can play a role in mitigating gender inequality in the process of sectoral reallocation of labour. We exploit the exogenous variations in educational attainment induced by the implementation of the 1986 Compulsory Education Law (CEL) in China. Using data from the 2018 wave of the China Family Panel Studies (CFPS) and a cohort difference-in-differences (DID) approach, we find that the CEL narrowed the gender gap in education for rural residents, but it did not reduce gender inequality in labour market outcomes, such as wage labour participation and wage rate. Our analysis reveals that this persistent inequality in labour market outcomes can be attributed to gender differences in migration and occupational choices. Specifically, rural males exposed to the CEL were more likely to migrate outside local provinces and work in low-skilled manufacturing sectors, while rural females tended to stay within local counties and work in low-skilled service sectors. Furthermore, we provide evidence that their differential migration responses are driven by household labour divisions and social gender norms, rather than disparities in cognitive skills.
Background: Micronutrient powder (MNP or Yingyangbao, a dietary supplement that contains multiple vitamins and minerals) programs can reduce the risk of anemia among children. One such program in China distributed free MNP to children aged 6–24 months in poor rural areas. However, there are indications that the generation of primary caregiver (i.e., parent or grandparent) may influence MNP feeding behavior. The purpose of this study was to investigate the prevalence and influencing factors of effective MNP feeding behavior among parents and grandparents in a rural developing setting.
Methods: We conducted a cross-sectional study of 884 caregivers and children in formerly impoverished rural areas of Sichuan Province using multi-stage random sampling. Data were collected on caregivers’ MNP feeding behavior, their core perceptions and health beliefs about MNP, children’s responses to MNP, MNP delivery patterns, and demographic characteristics. Influencing factors of parents’ and grandparents’ MNP feeding behavior were analyzed using two-level logistic regression.
Results: Total effective MNP feeding behavior rate among caregivers was 40.95%. Grandparents demonstrated higher MNP adoption than parents (χ2 = 4.445, P = 0.035). After controlling for sociodemographic characteristics, grandparents were more likely than parents to achieve effective MNP adoption (OR = 1.360, P = 0.035); child’s preference for MNPs (ORparental subgroup = 1.736, ORgrandparental subgroup = 1.496; P < 0.050) and caregiver’s self-efficacy (ORparental subgroup = 1.157, ORgrandparental subgroup = 1.393; P < 0.050) were influencing factors of feeding behavior for caregivers of both generations. Parents were also influenced by perceived barriers to feeding MNPs (OR = 0.904, P = 0.040), while grandparents were more strongly influenced by child’s discomfort to MNPs (OR = 0.240, P = 0.023) and caregiver’s knowledge about MNPs (OR = 1.557, P = 0.014).
Conclusion: Future efforts to improve the feeding behavior of caregivers in MNP programs both in China and abroad should improve children’s preference for MNP by changing its composition and taste, and increase caregivers’ feeding self-efficacy through health education. Moreover, parents should be taught to cope with time and ability barriers that may limit MNP adoption, while grandparents should be emphasized the importance and potential side effects of MNP.
