Spousal Income and Sick Leave: What do Twins Tell us About Causality?   总被引:1,自引:1,他引:0  
Theoretical arguments suggest that a higher socioeconomic status can improve health and as a consequence reduce the need for sick leave. The purpose of this study is to empirically investigate causal effects between spousal income and absence from the workplace due to sickness. To control for unobserved heterogeneity a Swedish sample of female twins and a semiparametric censored fixed-effects model was used. Results for dizygotic (fraternal) twins indicated that male spousal income, i.e., a non-shared environmental influence, reduced the share of income that was government-paid sickness benefits. Data on monozygotic twins, who have identical genes, provide a more complete control for unobserved heterogeneity. No causal effect was found in this case.

The passage of the Bankruptcy Abuse Prevention and Consumer Protection Act (BAPCPA) of 2005 culminated years of debate over the escalating number of bankruptcy filings and whether or not consumers were abusing the bankruptcy system. Our study focuses on the extent to which households seek bankruptcy protection without first attempting to restructure their debt or experiencing indicators of financial distress. Through multivariate regression analyses of longitudinal data from the Panel Study of Income Dynamics (PSID), we find a significant relationship between having prior financial problems and filing for bankruptcy. Our results also indicate that households that obtained consolidation loans were equally likely to file for bankruptcy as those that did not. We conclude that early interventions with financially distressed consumers may provide opportunities to reduce bankruptcy filings.

This paper examines the effect of children’s college expenses on household savings. The theoretical model introduces life-cycle savings into the quality–quantity model of fertility and derives predictions for the impact of expected expenses on parents’ savings. Using the actual amount of parents’ financial support reported in the Survey of Consumer Finances, the empirical model estimates the expected expenditures on children’s college education and investigates the effect of expected expenditures on parents’ savings. The results show that parents’ support for each of their children’s college expenses decreases with the number of children. The results are consistent with the predictions of the life-cycle theory of saving and consumption that households save in advance for expected expenses to smooth their consumption.

Traditional views of psychotherapy hold that termination allows both for a consolidation of therapeutic work and an opportunity to work through issues of separation and loss. Such a view suggests not only that those issues will resolve in treatment, but also that endings are inevitable, permanent, and that the feelings invoked can and should be mastered and worked through. Recent research on termination, attachment, loss and grieving suggests a different conception. Consideration of that research can better ground therapists in more nuanced techniques for ending treatment in both child and adult psychotherapy.

The impacts of two types of social desirability bias, self-deceptive enhancement (SDE) and impression management (IM), were examined on self-reports of gambling problems, measured by the South Oaks Gambling Screen (SOGS), and recent gambling behavior, as measured by the Timeline Followback (TLFB) method, in a sample of college students (N = 191), and a sample of treatment-seeking problem gamblers (N = 49). Consistent with our expectations, IM was negatively associated with SOGS scores in both samples. IM was most highly correlated with SOGS scores among treatment-seeking participants (r = −.44, p < .01). Substantial numbers of participants in both samples had high enough IM scores as to call into question the validity of their self-report gambling data, according to published interpretive guidelines. With respect to SDE, we had predicted that it would be positively related to gambling behaviors and gambling-related problems, but found that SDE was inversely related to SOGS scores in both samples. Very little evidence was found for social desirability effects on TLFB scores. Thus, preliminary evidence was obtained that self-report data on gambling problems, but not on gambling behavior (frequency of gambling and amount of time and money spent), may be susceptible to the effects of impression management in both college students and treatment-seeking gamblers.  相似文献

A set of low-risk gambling limits were recently produced using Canadian epidemiological data on the intensity of gambling behavior and related consequences (Currie et al. Addiction 101:570–580, 2006). The empirically derived limits (gambling no more than two to three times per month, spending no more than $501–$100°CAN per year or no more than 1% of gross income spent on gambling) accurately predicted risk of gambling-related harm after controlling for other risk factors. The present study sought to replicate these limits on data collected in three independently conducted Canadian provincial gambling surveys. Dose–response curves and logistic regression analyses were applied to gambling prevalence data collected in surveys conducted in 2001–2002 within the provinces of Alberta, British Columbia, and Ontario (combined sample N = 7,675). A comparable dose–response relationship between gambling intensity and risk of harm was found in each province. The optimal thresholds for defining an upper limit of low-risk gambling were similar across the three provinces despite variations in the availability and organization of legalized gambling opportunities within each region. These results provide additional evidence supporting the validity of the low-risk gambling limits. Quantitative limits could be used to augment existing responsible gambling guidelines.

The recent expansion of Internet gambling has stimulated debate, policy, and research on this relatively new phenomenon and its potential consequences. The current study focuses on bettors experiencing problems by sampling Internet gamblers who imposed limits on the amount they were allowed to deposit to a betting site. We analyzed the betting transactions over 18 months of all gamblers who subscribed to an online betting site in February, 2005 (N = 47,134), 567 of whom utilized the site’s self-limit feature. Self-limiting gamblers played a wider variety of games and placed more bets than others prior to imposing limits. After imposing limits, self-limiters reduced their activity, but did not reduce the amount they wagered per bet. Time spent gambling, not just money spent, appears to be an important indicator of gambling problems. Self-limit programs appear to be promising options for Internet gamblers at-risk for gambling problems.

Although there has been much speculation about the possible links between gambling and crime rates, relevant quantitative evidence has been practically non-existent in Australia to date. This paper reports the results of research that utilised a model designed to investigate the potential relationship between electronic gaming machine expenditures and property (income-generating) crime rates reported to police in local areas in South Australia in 2002–2003. The research found that the higher the expenditures on gaming machines in a particular local area per adult, the higher the income-generating crime rate in that area. No such relationship was found between gaming machine expenditure and non-income-generating crime rates. However, further research is required before any policy-relevant conclusions can be drawn.  相似文献

Excitement-seeking and related constructs have been associated with heavier gambling and negative health measures in problem and/or pathological gamblers. Most adults gamble recreationally and an understanding of the relationship between excitement-seeking as a motivation for gambling amongst subsyndromal gamblers has significant public health implications. Logistic regression analyses were used to examine a national sample of past-year recreational gamblers (N = 1,476) to identify characteristics distinguishing gamblers acknowledging gambling for excitement (“Excitement-seeking Gamblers” or EGs) and gamblers denying gambling for excitement (“Non-excitement-seeking Gamblers” or NEGs). EGs were more likely than NEGs to report alcohol use and abuse/dependence, any substance abuse/dependence, incarceration, large gambling wins and losses, more frequent and varied gambling, and symptoms of pathological gambling (i.e., at-risk gambling). Together, these findings indicate that EGs are more likely than NEGs to demonstrate problems in multiple areas characterized by impaired impulse control.  相似文献

A random telephone survey was conducted with a representative sample of 2,274 U.S. residents aged 14–21. The prevalence of problem gambling, as measured by the SOGS-RA, was 2.1%. Sixty-eight percent (68%) of the respondents had gambled in the past year, and 11% had gambled more often than twice per week. Males had much higher gambling involvement than females, and gambling involvement increased among older respondents. Blacks were less likely than average to have gambled in the past year, but if they gambled, they were more likely to do so frequently. Low SES respondents were less likely to have gambled in the past year, but if they gambled, they were more likely to be problem gamblers. Life transitions that are associated with assuming adult roles (employment, living independently of parents, non-student status) are also associated with greater gambling involvement. The rates of problem and pathological gambling were lower than those in an adult survey conducted earlier, when measured with the same questionnaire.  相似文献
