The Effect of Payment Methods on Risk Aversion

Risk aversion experiments such as those by Holt and Laury (2002, 2005) measure risk aversion by examining subjects’ responses to a series of probability-ordered choices. Subjects are paid real money rewards, using the random round payment method in which the amount is determined by one randomly selected decision. The findings reported here were obtained from 119 subjects who confronted the same choice set and payment amounts, but 60 of these subjects were paid using the random-round method while the remaining 59 were paid based on an average of all their choices, the accumulated value method. The accumulated value payment method simulates portfolio returns, as opposed to returns from stand alone investments. Results indicate that accumulated value subjects took more risk and made more inconsistent decisions.     

People Playing Games: The Human Face of Experimental Economics

Experiments can be used not only to test theory but also to measure preferences and assess heterogeneity of behavior. I discuss the design of experimental measures of altruism and trust, as well as their uses in assessing how behavior varies across individuals, and across partners that a given individual might encounter. Experiments show that women are more altruistic than men. The appearance of a partner substantially impacts trust and trustworthiness, in part through the association of attractiveness and skin tone with expectations about a partner's behavior.     

Women's participation in housing delivery: the case of Ezilweleni,South Africa

As part of a study on housing delivery in post-apartheid South Africa, research was conducted to explore women's participation. The interest in women was based on the assumption that their involvement would contribute to greater equity in the residential construction sector. Focus group discussions and a household survey were conducted. Participants were asked about their income sources and their involvement in various phases of housing delivery such as securing tenure, planning, procuring materials and building. The findings indicate that women influenced decisions about the level of infrastructural services in Ezilweleni. They participated in housing delivery but reverted to informal sector activities despite training in building. Both formal and informal education are necessary if greater equity is to be achieved in the construction sector.     

Is More Information Always Better? An Experimental Study of Charitable Giving and Hurricane Katrina

We report results of an experiment designed to assess the impact of Hurricane Katrina on the pattern and level of charitable contributions of donors. The study includes an experimental measure of charitable giving and targets three charities: the American Red Cross, the Salvation Army, and Oxfam International. In the experiment subjects make allocation decisions from three endowments ($10, $20, and $50) and with four different matching subsidies (0%, 25%, 50%, and 100%), with the matching amount provided by the experimenter. Two locations (Texas and Minnesota) and two information conditions are used. Survey measures of sympathy, risk perceptions, and perceptions of Katrina victims are also collected. The probability and amount of giving are responsive to the experimental design parameters—the endowment and match. We find evidence of “Katrina overload” as those closest to the disaster respond negatively to Katrina-related priming information. Perceptions of the psychological attitudes of the victims of the disaster have a significant effect on the amount given.     

DOES MOTHER'S EDUCATION MATTER IN CHILD'S HEALTH? EVIDENCE FROM SOUTH AFRICA1

Using the 1993 South Africa Integrated Household Survey, this paper studies the effect that mother's education through the knowledge channel has on children's health using height for age Z‐scores as health measure. Under a two‐stage least square methodology we find that an increase in 4 years on mother's education (approximately 1 standard deviation) will lead to an increase of 0.6 standard deviations on her child's height for age Z‐score. We also find, as the medical literature suggests, support for the hypothesis that mother's education is more important for children older than 24 months of age.     

Relational selling strategy and key account managers' relational behaviors: An exploratory study

Many companies see key account management as a potentially successful way to implement a relational strategy. Nevertheless, the literature suggests that strategy implementation at the sales force level is difficult to achieve, mainly because salespeople may not understand - nor accept - what they are requested to do. Despite their relevance, behaviors of key account managers have poorly been investigated. This article defines and tests a model of relational selling behaviors from the part of key account managers. Results show that the perception of the adoption of a relational selling strategy is associated with some specific key account managers' behaviors (customer-oriented selling, adaptive selling and team selling), but not with others (organizational citizenship behaviors). These findings suggest that potential discrepancies can exist between a relational selling strategy and its implementation at the key account manager level. Based on these results, theoretical and managerial implications are discussed.     

What is the most flexible component of wage bill adjustment? Evidence from Belgium

This paper decomposes wage bill changes at the firm level into components due to wage changes, and components due to flows of employment. It relies on an administrative matched employer–employee dataset of individual earnings merged with firms' annual accounts for Belgium over the period 1997–2001. The results are in line with what one would expect in a downward wage rigidity environment. On average, wage bill contractions result essentially from employment cuts in spite of wage increases. Wage growth of job stayers is moderated but positive; and wages of entrants compared with those of incumbents are no lower. The labour force cuts are achieved through both reduced entries and increased exits, due to more layoffs, especially in smaller firms, and wider use of early retirement, especially in manufacturing. In addition, the paper points out the role of overtime hours, temporary unemployment and interim workers in adapting hours worked to economic circumstances.     

Household Behavior with Imperfect Labor Markets

A household model with differential asset endowments and idiosyncratic transactions costs in accessing labor markets is developed to (1) explain membership of farm households to alternative labor regimes (sellers, employers, or self-sufficient in labor), (2) test for recursivity between production and consumption decisions selectively by labor regime, and (3) identify the determinants of differential labor productivity across labor regimes. The model is applied to a 1994 household survey of the Mexican land reform sector.
