Attitudes toward the Income Gap: Japan-U.S. Comparison
Get PDFEmploying the Japan-U.S. international survey, this study analyzed the cause of rising perception of the widening income gap in Japan. Between these two countries, their distinct value judgments on the substance of gap influence their recognition. Japanese have negative perception of the income gap caused by talent, academic background or luck; it seems relatively weak in the U.S. A large portion of Japanese also think one's income is recently decided by talent, academic background or luck though it should not be. Such disagreement between the desirable and recognized determinants of income is thought to raise their perception of the gap.
Overconfidence Increases Productivity
Get PDFRecent studies report that productivity increases under tournament reward structures than under piece rate reward structures. We conduct maze-solving experiments under both reward structures and reveal that overconfidence is a significant factor in increasing productivity. Specifically, subjects exhibiting progressively higher degrees of overconfidence solve more mazes. This result shows a positive aspect of overconfidence, which usually has been examined in its negative aspect as an expectation bias.
Time Discounting: The Delay Effect and Procrastinating Behavior
Get PDFThe delay effect, that people discount the near future more than the distant future, has not been verified rigorously. An experiment conducted by us in China confirms that, by separating the delay from the interval, the delay effect exists only within a short delay. The results are reliable, because the rewards paid were very large, in order to elicit the subjects' true preferences. The interval and magnitude effects are also confirmed. Finally, subjects' procrastinating behavior, as reported in the questionnaire conducted at the end of the experiment, is explained by the time discount rates and the degree of the delay effect revealed in the experiment.
Organization Adjustments, Job Training and Productivity: Evidence from Japanese Automobile Makers
Get PDFThis paper considers the demand for job training and its interaction with organization adjustments through rotation within a team and relocation across teams in response to demand and supply shocks. The analysis includes estimations of determinants of on-the-job training, and of how much such training contributes to improvements in individual productivity. We employ original assembler survey data from two Japanese automobile makers. We also investigate effects of the characteristics of workplace practices, including the behavior of foremen, on the incentives for individual assemblers to seek job training and productivity improvements.
Unhappiness after Hurricane Katrina
Get PDFIn August, September and October of 2005, the Monthly Surveys of Consumers fielded by the University of Michigan included questions about the happiness of a nationally representative sample of U.S. adults. The date of each interview is known. Looking at the data week by week, reported happiness dipped significantly in the first week of September, after the seriousness of the damage done by Katrina became clear. The impulse response of happiness is especially strong in the South Central region, closest to the devastation of Katrina. The dip in happiness lasted two or three weeks in the South Central region; in the rest of the country, reported happiness returned to normal after one or two weeks. In addition to the reaction to Katrina, happiness dipped significantly after the October 2005 earthquake in Pakistan. These results illustrate the potential of high-frequency happiness data to yield information about preferences over regional, national and international conditions by indicating the magnitude of the good or bad news conveyed by events.
Do People Seek to Maximize Happiness? Evidence from New Surveys
Get PDFAre subjective well-being (SWB) measures a good empirical proxy for utility? We evaluate one necessary assumption: that people’s preferences coincide with what they predict will maximize their SWB. Our method is to present survey respondents with hypothetical scenarios and elicit both choice and predicted SWB rankings of two alternatives. While choice and predicted SWB rankings usually coincide, we find systematic reversals. Furthermore, we identify factors—such as predicted sense of purpose, control over one‘s life, family happiness, and social status—that help explain choice controlling for predicted SWB. We explore how our findings vary with the SWB measure and the choice situation.
Time Discounting: Declining Impatience and Interval Effect
Get PDFMost studies have not distinguished delay from intervals, so that whether the declining impatience really holds has been an open question. We conducted an experiment that explicitly distinguishes them, and confirmed the declining impatience. This implies that people make dynamically inconsistent plans. We also found the interval effect that the per-period time discount rate decreases with prolonged intervals. We show that the interval and the magnitude effects are caused, at least partially, because subjects' choices are influenced by the differential in reward amount, while Weber's law solves neither the delay nor the interval effects.
The Long-Term Effects of the Chernobyl Catastrophe on Subjective Well-Being and Mental Health
Get PDFThis paper assesses the long-term subjective well-being and mental health toll of the Chernobyl disaster of 1986 in the general Ukrainian population and estimates the monetary differential necessary to compensate victims of the catastrophe. The analysis is based on two nationally representative Ukrainian data sets and reveals that even 20 years after the accident subjective well-being is negatively associated with self-reported assessments of having been affected by the catastrophe. The causal long-term effect of the disaster on life satisfaction is established by exploiting variation in official radiation data which are linked to survey respondents through information on their place of living in 1986. We find higher depression and trauma rates as well as poorer subjective life expectancy among those stronger affected by Chernobyl. Expressed in monetary terms, the estimated amount of income required to compensate for the experienced utility loss amounts to an annual cost of seven percent of Ukraine's GDP.Chernobyl catastrophe, subjective well-being, mental health, instrumental variable
