An empirical study of the purchase role structure in Korean families

The primary purpose of this research is to measure spousal influence in family decision-making situations in South Korea. Five thousand five hundred responses were collected nationwide, from a spectrum of age groups and from both genders. The (categorical) data were subjected to analysis by chi square and inspection of gamma values, by simple frequencies, and then by correspondent analysis. Results were consistent with expectations, in that it seems that the strong, cultural tradition of patriarchal dominance is overriding the increasing levels of economic development that might have been expected to lead to far higher levels of shared decision making between spouses. However, children, as well as women, do appear to have an increasing influence in family purchase decisions. © 1998 John Wiley & Sons, Inc.     

Shopping plans,buying motivations,and return policies: impacts on product returns and purchase likelihoods

Product return behavior and factors that contribute to product returns are an under-researched area, despite significant importance to manufacturers and retailers. The current research attempts to fill the gap by focusing on two factors that shape consumer purchase behavior: (1) whether purchases are planned or unplanned, and (2) whether hedonic or utilitarian motivations drive purchases. The findings show that purchase plans and buying motivations have distinctive and interactive impacts on pre-purchase concerns, self-estimated likelihood of returning purchases, and purchase intentions with or without return policies. When hedonic motivation drives purchases, unplanned (vs. planned) purchases lead to higher return concerns, higher return likelihood, and lower buying intentions. When utilitarian motivation drives purchases, planned and unplanned purchases have comparable return concerns, return likelihood, and buying intentions. This interaction effect on buying intentions dissipates when a lenient return policy is offered.     

Leadership competency inventory: A systematic process of developing and validating a leadership competency scale

This article reports psychometric evaluation of the Penn State Leadership Competency Inventory (LCI). The 32‐item LCI was validated on a sample of 323 managers in the health care industry. Preliminary validity and reliability evidence of the LCI was established through exploratory factor analysis (EFA), item‐total correlations, Cronbach's alpha coefficients, and confirmatory factor analysis (CFA). The four‐factor leadership competency scale, comprising supervisory and managerial competencies, organizational leadership, personal mastery, and resource leadership, accounted for 58% of variance. According to CFA results, the model fit of the four latent factors of the LCI was confirmed to be appropriate. Cross‐validation with other populations is needed to confirm the factor structure. Limitations and further research recommendations are discussed.     

Abusive Supervision,Psychological Distress,and Silence: The Effects of Gender Dissimilarity Between Supervisors and Subordinates

Previous research has shed light on the detrimental effects of abusive supervision. To extend this area of research, we draw upon conservation of resources theory to propose (a) a causal relationship between abusive supervision and psychological distress, (b) a mediating role of psychological distress on the relationship between abusive supervision and employee silence, and (c) a moderating effect of the supervisor–subordinate relational context (i.e., gender dissimilarity) on the mediating effect of abusive supervision on silence. Through an experimental study (Study 1), we found the causal path linking abusive supervision and psychological distress. Results of both the experimental study and a field study (Study 2) provided evidence that psychological distress mediated the relationship between abusive supervision and silence. Lastly, we found support that this mediation effect was contingent upon the relational context in Study 2 but not in Study 1. We discuss implications for theory and practice.     

Functional-coefficient models for nonstationary time series data

This paper studies functional coefficient regression models with nonstationary time series data, allowing also for stationary covariates. A local linear fitting scheme is developed to estimate the coefficient functions. The asymptotic distributions of the estimators are obtained, showing different convergence rates for the stationary and nonstationary covariates. A two-stage approach is proposed to achieve estimation optimality in the sense of minimizing the asymptotic mean squared error. When the coefficient function is a function of a nonstationary variable, the new findings are that the asymptotic bias of its nonparametric estimator is the same as the stationary covariate case but convergence rate differs, and further, the asymptotic distribution is a mixed normal, associated with the local time of a standard Brownian motion. The asymptotic behavior at boundaries is also investigated.     

Coordinating and competing in ecosystems: How organizational forms shape new technology investments

We consider firms in the context of their business ecosystems and explore how differences in the ways in which firms are organized with respect to complementary activities affect their decision to invest in new technologies. We argue that, in addition to creating differences in incentives and bureaucratic costs, firm‐complementor organizational form plays an important role in the firm's ability to coordinate accompanying changes in complementary activities so as to shape the benefits from investing early in the new technology. We test our predictions in the U.S. healthcare industry from 1995–2006. The study makes a strong case for viewing firms' competitive strategies in the context of their business ecosystems and for the existence of an important link between firms' coordination choices and their strategic investments.

An Integration of Constraints and Benefits Within an Older Women's Social Club: An Examination,Extension and Critique

ABSTRACT

The serious leisure perspective (SLP), which divides leisure activities into three distinct forms (serious, casual, and project-based), has been developed by Robert Stebbins over the last 40 years. This article evaluates the perspective as theory and as a typology. The theory associated with the SLP concerning social worlds, identification, and optimal leisure lifestyles is found to be generally untested because it has been developed in relation to the serious leisure form only. The validity of the typology is questioned on the grounds that “seriousness” is a continuum, rather than discrete categories, and that most leisure activities can be engaged in with varying degrees of seriousness. It is proposed that the SLP be replaced by a more flexible, open research approach, the Leisure Experience Perspective, which consolidates features of the SLP and other research traditions and theoretical perspectives.     

On the Value of Municipal Bond Insurance: An Empirical Analysis

Using a large sample of municipal bond data from 2001 to 2010 in the U.S., this paper documents the time variation of the value of municipal bond insurance, estimated from the insured and uninsured bonds yield at issue differentials. We find that insured municipal bonds carry significant lower yields at issue compared to those of the equivalent uninsured bonds before 2008. However, this cost saving disappeared with the aftermath of the subprime credit crisis. We find that the supply of bonds and the level of market interest rates to have significant positive impacts on the time‐varying value of bond insurance. We also detect asymmetric response of these yield differentials to rises and declines of market interest rates. Economic intuition suggests that the value of municipal bond insurance is a function of business cycles but our tests support the contrary, which may be explained by the habitat preference of municipal bonds issues.     

Efficient Consumer Altruism and Fair Trade Products

Consumers have shown a willingness to pay a premium for products labeled as “FT” and a preference for retailers that are seen to be more generous to their suppliers/employees. A FT product is essentially a bundle of a base product and a donation to the supplier (e.g., a coffee farmer). An altruistic rational consumer will only choose this bundle if doing so is less expensive than buying the base product and making a direct donation. For FT to be sustainable either in a competitive equilibrium or in a monopolistic environment this bundling must yield an efficiency. This efficiency is generated in the following context. A supplier’s investment reduces the retailer’s cost or boosts the final product’s quality, but this investment is not immediately observable and cannot be enforced, hence there exists a moral hazard problem. In this environment, the altruism of the consumer can facilitate a more efficient contract: by paying the supplier more the retailer can both extract more consumer surplus and increase the level of contracted investment, while preserving the supplier’s incentive compatibility constraint. We assess our model in the context of the coffee industry.     

Simulating the Effects of Railroad Mergers

The purpose of this paper is to add to the empirical literature regarding merger simulation analysis by examining the effect of railroad mergers on railroad market power. This is done by measuring railroad profits and revenue/variable cost ratios corresponding to different degrees of intrarailroad competition for movements of Kansas export wheat to Houston, Texas. Two models are developed to achieve the objectives of the study. A network model of the wheat logistics system is used to identify the least cost transportation routes from the Kansas study area to the market at Houston. A profit improvement algorithm, which identifies Nash equilibrium prices, is developed to measure the amount by which railroads can profitably raise their prices above variable cost. The results of the study have implications for U.S. railroad merger policy. The paper indicates that railroad mergers do not necessarily increase railroad market power or make railroad shippers worse off. Instead, the study demonstrates that the impact of railroad mergers on shippers and railroads depends on factors that vary geographically, such as the degree of intrarailroad and intermodal competition in the area.
