2D:4D and individual satisfaction: Evidence from the Russian social survey
Is in utero exposure to testosterone (approximated by finger 2D:4D ratio) correlated with the perception of wellbeing?
The question matters for understanding the role of non-cognitive determinants of economic behavior. We
use unique data from the Russian Longitudinal Monitoring Survey (RLMS-HSE) that contains markers for testosterone
exposure and find support for the correlation between female 2D:4D and average measures of subjective
well-being which include: satisfaction with life, work, wage and economic conditions, and with opportunity
for professional growth. The most conclusive results are obtained for the digit ratios of women's right
hands. Both linear negative and inverse U-shaped associations were significant subject to multiple controls. Ushaped
relationships are also observed in the limited number of regressions for males. Even though the data sets
do not allow us to account for problems of endogeneity, the regression analyses suggest that the net direct effect
of 2D:4D is small but statistically significant.
Significant positive effects on subjective well-being can already be observed after a period as short as 4 weeks. Policy makers should support the provision of such time-efficient programs which are appealing to overweight population groups. Copyright Swiss School of Public Health 2015
Measuring indirect importance of various attributes is a very common task in marketing analysis for which researchers use correlation and regression techniques. We have listed and illustrated some common problems with widely used latent importance measures. A more theoretically sound approach – the Shapley Value decomposition – was applied to a rich data set of US internet stores. The use of store-level data instead of respondent-level data allowed us to reveal the factors, which are powerful in explaining, why some stores have higher rates of willingness to make repeat purchases than the others. By confronting the indirect importance and performance measures for three different internet stores, we have revealed strengths, weaknesses, attributes that the company should bring customers’ attention to and attributes improvement of which is not of a high priority.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
