Raising charitable children: the effects of verbal socialization and role-modeling on children’s giving

This paper uses nationally-representative data from the PSID and CDS to estimate the causal effects of two parent socialization actions—talking to children about giving and role-modeling—on children’s decisions whether or not to give to charity. We develop an identification framework based on the intra-household allocation and cultural transmission literatures that shows how different assumptions about parental response to time-varying unobserved changes in children’s prosocial values can be combined with the child fixed effects estimate and the difference between siblings’ over-time-differences estimate to infer a bound on the causal effect of parental action to socialize their children. Under the identifying assumption we think is most reasonable for socializing the willingness to give to charity, that parents treat the socialization actions of others as cultural substitutes, our estimates imply that talking to children about giving raises the probability of children’s giving by at least .13. We find no evidence that parental role-modeling affects children’s giving, except among non-African-American girls. The identification framework and substantive results have implications for those with a general interest in using data from naturalistic settings to estimate causal effects of parental socialization actions, those interested in the external validity of laboratory findings, and those interested in the socialization of warm glow.     

Changing a Leopard's Spots: A New Research Direction for Organizational Culture in the Operations Management Field

Operations Management (OM) research on organizational culture has to change to be able to inform practice. Currently, organizational culture research in OM is largely confined to narrow topical and methodological niches and culture is most frequently used as an explanatory variable in quantitative, survey‐based research. We argue that the relegation of culture to this niche is due to self‐imposed methodological blinders that hobble the OM field. We then present four research imperatives to reinvigorate organizational culture research within our field. We urge OM scholars to view culture as a dynamic concept that can be influenced, to adopt alternative methods, to use non‐traditional data sources, and to rethink assumptions about dependent variables. We also identify gaps in the current knowledge and new research questions for the OM domain. We conclude that the field of OM could greatly expand its understanding of organizational culture and in so doing greatly improve business practice, but that to do so will require a change in the culture of the operations management research community.     

Allocation of Returned Products among Different Recovery Options through an Opportunity Cost–Based Dynamic Approach*

In a make‐to‐order product recovery environment, we consider the allocation decision for returned products decision under stochastic demand of a firm with three options: refurbishing to resell, parts harvesting, and recycling. We formulate the problem as a multiperiod Markov decision process (MDP) and present a linear programming (LP) approximation that provides an upper bound on the optimal objective function value of the MDP model. We then present two solution approaches to the MDP using the LP solution: a static approach that uses the LP solution directly and a dynamic approach that adopts a revenue management perspective and employs bid‐price controls technique where the LP is resolved after each demand arrival. We calculate the bid prices based on the shadow price interpretation of the dual variables for the inventory constraints and accept a demand if the marginal value is higher than the bid price. Since the need for solving the LP at each demand arrival requires a very efficient solution procedure, we present a transportation problem formulation of the LP via variable redefinitions and develop a one‐pass optimal solution procedure for it. We carry out an extensive numerical analysis to compare the two approaches and find that the dynamic approach provides better performance in all of the tested scenarios. Furthermore, the solutions obtained are within 2% of the upper bound on the optimal objective function value of the MDP model.     

Emergency Department Staff Planning to Improve Patient Care and Reduce Costs

In the face of high staffing costs, uncertain patient arrivals, and patients unsatisfied with long wait times, staffing of medical emergency departments (EDs) is a vexing problem. Using empirical data collected from three active EDs, we develop an analytic model to provide an effective staffing plan for EDs. Patient demand is aggregated into discrete time buckets and used to model the stochastic distribution of patient demand within these buckets, which considerably improves model tractability. This model is capable of scheduling providers with different skill profiles who work either individually or in teams, and with patients of varying acuity levels. We show how our model helps to balance staffing costs and patient service levels, and how it facilitates examination of important ED staffing policies.     

Does financial self-efficacy explain gender differences in retirement saving strategies?

Research indicates that women remain less financially prepared for retirement than are men. Little research has examined the gender difference in use of retirement plans. The present research assessed the gender difference in use of employer-sponsored and private retirement plans, and sought to account for this difference. Social status and human capital factors, occupation and industry of employment, and sense of financial self-efficacy were expected to account for gender differences. Findings indicated gender has no relationship with use of private retirement plans. However, females were found to be less likely to use an employer-sponsored plan, and this was largely accounted for by gender differences in occupation.     

A Meta-Analytic Review of the Association Between Disgust and Prejudice Toward Gay Men

ABSTRACT

A sizeable number of studies have documented a relationship between heterosexual persons’ experience of disgust (measured as an individual difference variable or induced experimentally) and prejudice toward gay men (i.e., homonegativity). Yet, to date, no one has attempted to meta-analytically review this corpus of research. We address this gap by conducting a meta-analysis of published and unpublished work examining heterosexual men and women’s disgust and their homonegativity toward gay men. Fourteen articles (12 published, two unpublished) containing 17 studies were analyzed (N = 7,322). The average effect size for disgust sensitivity studies was moderate to large (d = 0.64), whereas for disgust induction studies, the effect was large (d = 0.77). No evidence of effect size heterogeneity emerged. Future directions and recommendations for methodological improvements are outlined.     

Demographic Cycles,Cohort Size,and Earnings

This article examines whether position in the demographic cycle is an important factor in determining earnings and earnings growth. Earnings equations for white males are estimated by using March Current Population Survey data. Position in the demographic cycle is captured by including both measures of own cohort size and the size of surrounding cohorts in the estimated earnings equations. Position in the demographic cycle matters. Increases in own cohort size lead to flatter earnings profiles, whereas increases in the size of surrounding cohorts are associated with steeper earnings profiles. The net effect is that those who enter the labor market before or after the peak of the demographic cycle start out with lower earnings but experience faster earnings growth. This pattern is uniform across all schooling groups: high school dropouts, high school graduates, those with some college, and college graduates.     

Female work experience,employment status,and birth expectations: Sequential decision-making in the Philippines

The influence of women’s birth parity and accumulated market skills on their current labor force participation and birth expectations is examined within a sequential choice framework, Analysis of household data from the 1973 Philippines National Demographic Survey suggests these patterns: (a) women who have accumulated larger families work less in the current period and anticipate fewer additional births; (b) women with more past work experience tend to work more hours in the current period; and (c) work experience appears to have only a weak negative effect on birth expectations among older women.     

Skin Color and Intelligence in African Americans: A Reanalysis of Lynn's Data

Finding a modest yet statistically significant correlation between skin tone and vocabulary test scores among African Americans, Lynn (2002) concludes that intelligence in African Americans is significantly determined by the proportion of Caucasian genes (p. 365). In this reanalysis of Lynn's data, I demonstrate that his bivariate association disappears once childhood environmental factors are considered. Therefore, a genetic link between skin color and intelligence among African Americans cannot be supported in his data. Investigators seeking to establish a genetic connection between racial ancestry and intelligence must move beyond simple bivariate results to address the confounding influence of environmental conditions that affect cognitive development.
