This study examined the relation of fluid and crystallized intelligence with extrinsic (occupational skill level, income) and intrinsic (job satisfaction) career success as well as the incremental predictive validity of conscientiousness and its facets. Participants (N = 121) completed the Reynolds Intellectual Assessment Scales (RIAS), the Revised NEO Personality Inventory (NEO-PI-R), and repo...

This article uses recently published time series data for the Organization for Economic Cooperation and Development countries to estimate income elasticities for health care expenditures. Several different models and alternative specifications are examined to determine the sensitivity and robustness of the estimated relationships. Income is the dominant-determinant of health care spending and l...

This paper uses an overlapping generations model to analyze the relationship between economic development and income distribution and the effect of government taxation and transfers on the distribution of income. Individuals differ in their inherited stocks of human capital and therefore in their productivity and income, and their leisure and investment decisions. Individual productivity depend...

METHODS The Russia longitudinal monitoring survey (RLMS) is a survey (n = 7696) that is representative of the Russian population. With multilevel regressions bot...

BACKGROUND Geographical inequalities in suicide have risen dramatically across 47 prefectures in Japan since 1995. We sought to examine temporal changes in the associations between prefecture-level economic conditions and completed suicide during the recent 35 years, controlling for individual composition in each prefecture. METHODS Based on quinquennial vital statistics and census data from ...

The literature argues that income growth leads to increased demand for environmental quality and thus reduction in pollution. Using a utility theoretic model, we hypothesize that the income±pollution relationship should depend on the level of disamenity of the pollutant. We proxy for disamenity using the toxicity of releases. For counties in the United States, the functional relationship betwee...

Using data from the General Social Survey, we study the role of income in self-reported happiness. Unexpected income gains increase happiness but individual happiness is not very persistent over time. Relative income is more important than absolute income, in particular, income relative to individuals’ own cohort working in the same occupation group, and living in the same region. Perceptions a...

The  present  study  aimed  at  investigating  DIF  sources  on  an  EFL  reading  comprehension test.  Accordingly,  2  DIF  detection  methods,  logistic  regression  (LR)  and  item  response theory  (IRT),  were  used  to  flag  emergent  DIF  of  203  (110  females  &  93  males)  Iranian EFL examinees’ performance on a reading comprehension test. Seven hypothetical DIF sources were examin...
