Who values the family‐friendly aspects of a job? Evidence from the Japanese labour market

Women with family responsibilities such as child‐rearing generally prefer jobs with flexible working conditions. According to the theory of compensating wage differentials, women working in such family‐friendly jobs are paid less than those working in family‐unfriendly jobs. The present paper investigates whose wages are more greatly affected by the family‐(un)friendly aspects of their jobs. Based on a longitudinal survey of Japanese women, we found that among several family‐(un)friendly attributes of a job, only commuting time requires a wage premium, and most of the premium is associated with job changes made by part‐time‐working married women.     

The communication cost of selfishness

We consider how many bits need to be exchanged to implement a given decision rule when the mechanism must be ex post or Bayesian incentive compatible. For ex post incentive compatibility, the communication protocol must reveal enough information to calculate monetary transfers to the agents to motivate them to be truthful (agents' payoffs are assumed to be quasilinear in such transfers). For Bayesian incentive compatibility, the protocol may need to hide some information from the agents to prevent deviations contingent on the information. In both settings with selfish agents, the communication cost can be higher than in the case in which the agents are honest and can be relied upon to report truthfully. The increase is the “communication cost of selfishness.” We provide an exponential upper bound on the increase. We show that the bound is tight in the Bayesian setting, but we do not know this in the ex post setting. We describe some cases where the communication cost of selfishness proves to be very low.     

Trader Survival: Evidence from the Energy Futures Markets

This study analyzes the adaptation of traders and the determinants of trader survival during a period of changing market structures. Our unique sample of transactions level data covers the introduction of electronic trading in the NYMEX energy futures market. The results show that most floor traders adapted to the side‐by‐side electronic and open outcry trading, although trader attrition increased and the profitability of surviving traders declined dramatically. It is also found that trading profits, trader experience and sophistication, and dual trading have a positive effect on the probability of trader survival. Scalpers are less likely to exit trading in pure open outcry trading, but are more likely to fail than traders who hold open positions longer in side‐by‐side trading. Finally, traders trading in multiple energy futures markets and those who use both the exchange floor and electronic trading appear to have a survival advantage in side‐by‐side trading. © 2011 Wiley Periodicals, Inc.

Enforcement and disclosure under regulation fair disclosure: an empirical analysis

While Regulation Fair Disclosure (FD) was designed to benefit investors by curbing the selective disclosure of material non‐public information to ‘covered’ investors, such as analysts and institutional investors, it can also impose costs. This paper finds that FD levies three kinds of enforcement and disclosure costs. First, investors cannot recover as part of an SEC enforcement action the gains to covered investors from their alleged use of the non‐public information. Second, investors lose because the market responds negatively to an SEC enforcement announcement. Third, investors suffer because some companies post their FD filings well after the due date, without earlier public disclosure.     

Reframing the Past: Thoughts about Business Leadership and Decision Making under Uncertainty

How do business leaders make decisions in the face of uncertainty?More important, how do business and economic historians writea narrative that links a business problem, its proposed solution,and the outcome of this action without allowing the successor failure of the decision to determine the trajectory of thestory? Counterfactual hypotheses and contextual analysis providetwo tools that can help historians minimize the distortionsof hindsight and recover a sense of the contingency that surroundsall decisions.     

A Comparative Analysis of Ethical Perceptions in Marketing Research: U.S.A. vs. Canada

The study compares Canadian and U.S. marketing researchers' attitudes, perceptions and intentions related to several areas of ethical concern. A particular focus involves salience of norms common to marketing research codes of ethics (COEs) and familiarity of such codes to marketing research professionals. Researchers' attitudes towards today's ethical climate are identified and compared between the two countries. Relationships are examined between familiarity, ethical intention and salience. Results indicate that U.S. and Canadian marketing researchers have similar perceptions of the relative importance of specific ethical norms, but worldwide COEs do not reflect these perceptions. Canadian marketing researchers report having a greater familiarity with their firms' adopted COEs, but this finding is moderated by the type of researcher. Among other findings, results indicate that familiarity influences ethical intention only for highly salient issues.     

Deregulating Overtime Hours Restrictions on Women and its Effects on Female Employment: Evidence from a Natural Experiment in Japan

This paper provides novel evidence on the effect of deregulating overtime hours restrictions on women by using the 1985 Amendments to the Labour Standards Act (LSA) in Japan as a natural experiment. The original LSA of 1947 prohibited women from working overtime exceeding two hours a day; six hours a week; and 150 hours a year. The 1985 Amendments exempted a variety of occupations and industries from such an overtime restriction on women. Applying a difference‐in‐difference model to census data, we find causal evidence pointing to the positive effect of this particular piece of labour market deregulation on the proportion of female employment. We then carry out a series of sensitivity analyses to ensure the robustness of our finding. Especially, we conduct a falsification test and an event study to show that our causal inference is not threatened by the differential pretreatment trends. Finally, we use quantile regressions and find that for jobs with more rapidly growing proportion of female employment, the effect of the exemption from the overtime work restriction on women is larger.     

The optimal size of Japan's public pensions: An analysis considering the risks of longevity and volatility of return on assets

There are two main pension systems: the Defined Benefit (DB) pension system and the Defined Contribution (DC) pension system. Each system has advantages and disadvantages. This paper investigates to what degree Japan should maintain a DB public pension system which offers the benefit of sharing risk and to what degree Japan must adopt a DC pension system to eliminate intergenerational imbalance. The risks of longevity and volatility of return on assets are incorporated into the simulation model. As a result of the simulation analysis, a replacement rate of 20–30% would be adequate for future generations if the expected return on assets and the wage growth rate are at the same level. Meanwhile, if the former is 2% points larger than the latter, a replacement rate of 0% or full-scale privatization would be desirable.
