Peer Effects among Swimmers

We develop a novel identification strategy and examine various aspects of peer effects using swimming data. We find that the performance of adjacent competitors positively influences swimmers' performances. In particular, swimmers are influenced by slower‐lane peers, suggesting that being chased improves one's performance. We use absenteeism data to directly compare the performances of swimmers with and without peers. We have found that swimmers swim faster with peers swimming behind them than when swimming alone, but that they swim slower with peers swimming ahead. Finally, we find that observability is a key determinant of peer effects, by comparing freestyle and backstroke competitions.     

The nature of informal food bazaars: Empirical results for Urban Hanoi,Vietnam

This paper aims to study the interesting phenomenon of informal food markets in urban areas, which have been neglected in the past research. Based on an empirical study of consumer choice between informal and formal markets (markets built-up by street hawkers vs. government-planned markets), this paper provides a basis for understanding the nature of informal markets in the Vietnamese context. The results show that cheap price and convenience (proximity) are important in shaping the choice by consumers for informal markets for food, while close relationship with sellers or services provided by sellers are not. Shoppers with higher concern for freshness and safety of fresh food are more likely to shop at formal markets. Additionally, low-income shoppers are found significantly inclined toward informal markets, while higher-income shoppers tend to shop at formal markets. Therefore, these two types of market should be viewed as two marketplaces to serve two segments of consumer groups, rather than two markets competing for a share of the business.     

Mommy-track backlash

"Please don't tell me that I need to have a baby to have this time off." Those words were still ringing in the ears of Jessica Gonon an hour after a tense meeting with Jana Rowe, one of her key account managers. Jessica, the vice president of sales and customer support at ClarityBase, considered Jana's request for a four-day workweek, for which she was willing to take a corresponding 20% cut in pay. Although the facts seemed simple, the situation was anything but. Just last week, Davis Bennett, another account manager, had made a similar request. He wanted a lighter workload so he could train for the Ironman Triathlon World Championship. Both Jana and Davis were well aware that Megan Flood, another account manager, had been working a reduced schedule for nearly two years. When she was hired, Megan had requested Fridays off to spend time with her two young sons. And since she came highly recommended and the talent pool was tight, Jessica had agreed to the arrangement. The eight account managers at ClarityBase were in charge of helping the company's largest clients install and maintain database applications, which often required no small amount of hand-holding and coddling. Because Megan had an abbreviated schedule, the other account managers were assigned the more difficult clients. But if Jessica agreed to a shorter workweek for Jana and Davis, who would take on the toughest customers? And what would happen if the other account managers started asking for similar deals? How can Jessica maintain the productivity of her department and meet her staff's needs for flexible work schedules while striking an equitable solution for both parents and nonparents? Four experts advise Jessica on her next move in this fictional case study.     

Platform strategy of video game software in Japan, 1984–1994: theory and evidence

This paper analyzes a model of platform competition in markets of system products composed of hardware and complementary software, with a specific focus on exclusive contracting. When hardware products are strongly differentiated, or when consumers value the marginal benefit of additional software variety highly, we find that, in equilibrium, hardware firms will engage in exclusive contracting of software development. This finding is strongly supported by our empirical results in the Japanese home video game industry, dominated by Nintendo from 1984 to 1994. Copyright © 2010 John Wiley & Sons, Ltd.     

Payment card rewards programs and consumer payment choice

By using a unique data set that contains detailed information about consumer payment choice and consumers’ attitudes toward each payment method, we estimate the effects of payment card rewards on consumer choice of payment methods. Our approach allows us to control for consumer heterogeneity. We find the effects of rewards to be statistically significant across five retail types. Our policy experiments suggest that for the sub-population who hold both credit and debit cards, removing rewards would increase their share of paper-based payment methods (i.e., cash and checks), measured in terms of in-store transactions, by no more than 4 percentage points.     

WTO Negotiations and Other Agricultural Trade Issues in Japan

This paper examines the current developments in WTO negotiations on agriculture and discusses the issues of greatest concern to Japan as well as agricultural issues in free trade area (FTA) negotiations relating to Japan. With regard to agricultural policies in Japan it is stressed that: (1) structural reform in Japanese agriculture is essential to promote the WTO agricultural negotiations and to make negotiations on FTAs more effective and prompt; (2) Japan must consider various measures to increase the investment of capital from outside agriculture and the accumulation of new human capital; and (3) there should be increased market competition in Japanese agriculture so that productive resources can be better concentrated in efficient farms and farm businesses. On international issues, it may be desirable to establish an international forum, particularly among Asian countries, to discuss important agricultural issues in the region. This forum should consider not only agricultural tariff reductions, but also sanitary and phyto‐sanitary (SPS) measures that might be addressed in working toward a broader FTA in Asia. The objective would be for Japan to play a strong leadership role in seeking wider cooperation on agricultural policies and agricultural resource management together with potential FTA partners in the Asian region.     

Life cycle and bequest savings A study of Japanese and U.S. households based on data from the 1984 NSFIE and the 1983 survey of consumer finances

This paper investigates whether the elderly save or dissave in light of two newly available sets of cross-section micro data, the 1983 “Survey of Consumer Finance” for the United States and the 1984 “National Survey of Family Income and Expenditure” for Japan. Contrary to dominant earlier findings we find for the United States that families after retirement dissave on average about a third of their peak wealth by the time of death, leaving the rest (mostly their homes) as bequests. For Japan, special handling is made to eliminate possible sample selection bias due to the different economic characteristics of the elderly forming independent households and those living with children. We find that the elderly belonging to both groups continue to save, and moreover, there appear to be significant signs of ongoing wealth transfer between the generations. The data in both countries also show that the elasticity of saving with respect to a life time income measure is significantly greater than unity, and more strongly so within higher age groups. J.

Traditional bazaar or supermarkets: A probit analysis of affluent consumer perceptions in Hanoi

Abstract

This paper sheds light on the preferences and behaviour of Vietnamese consumers in an emerging market economy. We analysed survey data of affluent consumers in Hanoi by using a binary choice Probit model for traditional bazaars versus supermarkets. The purpose of the analysis was to measure the factors which influence decision-making by consumers when selecting particular retail outlets for shopping. Our results show that freshness, price and convenience are important in shaping the choice by consumers for traditional outlets for fresh food, while price played a key role in selecting shopping outlets for processed food and drinks and non-food products. The results provide a basis for understanding the strengths and weaknesses of the old and the new retail outlet formats.
