SUMMARYThis paper analyzes the determinants of the perceived stress level of workers with a special focus on the effects of commuting, while controlling for personal and work-related characteristics. Using ordered logistic regression we find that several dimensions of the commuting situation, such as impedance, control and predictability of commuting, significantly influence the perceived stress level. Therefore, stress and stress-related health problems should be taken into consideration when analyzing the economic costs of commuting.

This paper explores individual motives for volunteering. The analysis is based on the interpretation of volunteering as a consumption good (consumption model) or as a mean to increase individual's own human capital (investment model). We present an econometric framework taking into account self selection into volunteering and simultaneity between the volunteering decision and the determination of income in order to test these two models and to identify the underlying motives.We find strong statistical evidence for the investment model with a highly robust and significant impact of volunteering on the wage rate. Within the framework of the investment model it turns out that the number of volunteering hours plays a major role in explaining this wage premium. This supports the significance of skill acquisition to accumulate human capital, the importance of deepening of social contacts and signalling willingness to perform. As far as the consumption model is concerned we find no clear statistical evidence for its validity.

Many publishers use an honor system for selling newspapers in the street. We conducted a field experiment to study honesty in this market, finding that a moral reminder increases the level of honesty in payments, whereas the same message has no effect on whether one is honest. Reminding customers of the legal norm has no effect. We argue that these results are consistent with a preference for honesty, based on an internalized social norm. Auxiliary evidence suggests that the moral message remains effective when it is posted for longer periods, and even when it is removed again.

Pension systems and reforms thereof are often discussed in the context of financial viability. In industrialized countries, these debates grow in intensity with the aging of the population; however, an increase in retirement age may create unintended side effects with regards to retiree health or healthcare costs. This study empirically analyzes the effect of (early) retirement on individual inpatient and outpatient healthcare expenditure in Austria. We use comprehensive labor market and retirement data from the Austrian Social Security Database, together with detailed information about individual inpatient and outpatient healthcare service utilization in the province of Upper Austria. To account for endogeneity in retirement decisions, we exploit exogenous variation in the early retirement age as induced by two Austrian pension reforms (i.e., those in 2000 and 2003). We find there to be significant negative effects of retirement on healthcare expenditure. For both genders, retirement reduces subsequent expenditure for outpatient medical attendance and hospitalization. Analyses of disaggregated components of healthcare expenditure confirm a positive health effect caused by physical and emotional relief following retirement. Apart from direct health effects, the results also reveal behavioral changes in the utilization of healthcare services. These changes in health behavior seem particularly relevant among blue-collar workers.JEL Classifications: I11, I12, J26, H51
