L'inégalité, frein à la croissance? L'effet de l'inégalité des revenus sur les taux de croissance de dix pays de l'Europe de l'Ouest

Dans le présent article, le lien entre la distribution des revenus et les taux de croissance est analysé de manière empirique à l'aide d'une série de régressions. A l'opposé des études antérieures, la relation en question est examinée à la fois dans l'espace et dans le temps: l'auteur construit un panel basé sur une période de 40 ans et sur un échantillon homogène, composé par dix pays de l'Europe de l'Ouest. Démontrant une corrélation négative significative entre les deux variables, les résultats confirment la théorie qui identifie l'inégalité comme un frein à la croissance. Il en suit que les facteurs concernant la distribution du revenu se répercutent sur la croissance économique à moyen et long terme au même titre que les variables macroéconomiques traditionnelles. Ces résultats sont discutés à la lumière de deux transformations économiques récentes, le cas de la croissance américaine d'une part et la globalisation des économies d'autre part.     

Subjective Invulnerability,Optimism Bias and Adjustment in Emerging Adulthood

The relationship between subjective invulnerability and optimism bias in risk appraisal, and their comparative association with indices of risk activity, substance use and college adjustment problems was assessed in a sample of 350 (M _age = 20.17; 73% female; 93% White/European American) emerging adults. Subjective invulnerability was measured with the newly devised adolescent invulnerability scale (AIS). Optimism bias in decision-making was assessed with a standard comparative-conditional risk appraisal task. Results showed that the danger- and psychological invulnerability subscales of the AIS demonstrated strong internal consistency and evidence of predictive validity. Subjective invulnerability and optimism bias were also shown to be empirically distinct constructs with differential ability to predict risk and adjustment. Danger invulnerability and psychological invulnerability were more pervasively associated with risk behavior than was optimism bias; and psychological invulnerability counter-indicated depression, self-esteem and interpersonal problems. Results support recent claims regarding the “two faces” of adolescent invulnerability. Implications for future research are drawn.     

Clinically Significant Trauma Symptoms and Behavioral Problems in a Community-based Sample of Children Exposed to Domestic Violence

This study assessed the associations of characteristics of domestic violence incidents with clinically significant levels of traumatic symptoms and behavioral problems in a socio-economically and ethnically mixed sample of 687 children participating in a community-service program for children witnessing violence. Study predictors included child/family demographic characteristics, type and chronicity of exposure, and child’s perceptions of control over the event and threat to personal safety. Outcomes consisted of traumatic symptoms and behavior problems. Results showed that perceived threat and control were associated with greater odds of clinically significant levels of several trauma symptoms (and behavior problems in the case of perceived threat) after adjusting for effects of demographic factors and violence characteristics. Child co-victimization increased odds of reaching clinically significant levels of traumatic symptoms compared to children who witnessed the event but were not victimized. Female sex and White ethnicity increased odds of specific trauma symptoms and behavior problems. Increasing age reduced odds of some trauma symptoms. Associations between predictors and one outcome measure did not generalize across the other outcome measure. Implications of study findings, and directions for future research are discussed.     

Factors Influencing the Higher Education Decisions of Criminal Justice Professionals

Criminal justice professionals are a potential source of students for many criminal justice programs, especially those in metropolitan areas. This study explored factors that influenced the higher education decisions of 480 Northwestern Ohio criminal justice employees (e.g., municipal police officers, sheriff deputies, jail staff, and prison staff). Most indicated a desire to pursue higher education. Among those indicating an interest in earning a degree, cost and convenience were the most significant factors in their choice. The availability of evening and weekend classes, availability of a part-time curriculum, availability of financial aid/tuition reimbursement, total credit hours required for the degree, the field experience of faculty, and flexibility in admission requirements were all significant factors. Location was also very significant. Most respondents indicated that they would not travel more than thirty minutes to attend classes.     

Conflict Expectations and the Paradox of Economic Coercion

Despite their increasing importance, there is little theoretical understanding of why nation-states initiate economic sanctions or what determines their success. These events are often explained away as "symbolic politics" driven completely by domestic-level factors. This article develops a simple game-theoretic model of economic coercion to show that both "senders" and "targets" of economic coercion incorporate expectations of future conflict as well as the short-run opportunity costs of coercion into their behavior. Conflict expectations have a paradoxical effect on coercion events. First, senders that anticipate frequent conflicts will be more willing to initiate economic coercion, even if such attempts are costly. Senders that anticipate few conflicts will not threaten sanctions unless they incur minimal costs and the target would suffer significantly. While a robust anticipation of future disputes might make the sender prefer a coercive strategy, it also reduces its ability to obtain concessions. Target states that anticipate frequent conflict with the sender will make fewer concessions. Ironically, a sender will obtain the most favorable distribution of payoffs when it cares the least about its reputation or the distribution of gains. These hypotheses are tested statistically, with the results strongly supporting the conflict expectations model.
