The effect of leniency programs on endogenous collusion

The objective of a leniency program is to reduce sanctions against collusion if a participant voluntarily confesses his behavior or cooperates with the public authority’s investigation. Constructing a model in which the detection probability varies over time, Harrington (2008) pointed out that there are three channels through which the leniency program can affect the collusion amount; furthermore, he presented a sufficient condition under which the maximum leniency is optimal. After extending the model by endogenizing the degree of collusion as well as equilibrium selection in the self-reporting stage, we revealed that the Race to the Courthouse effect disappears and that the maximum reduction is always optimal.     

The effect of frequent flyer programs: A case study of the Korean airline industry

Frequent flyer programs are important for airlines in Korea in their marketing of services. This paper develops a conceptual model to investigate the effect of such programs by examining the relationships them and, airline service quality, pricing, passenger satisfaction, airline image, and airline selection. Path analysis is used to analyze data collected from Korean international air passengers. The results show that frequent flyer programs have direct and indirect effects on pricing, passenger satisfaction, airline image, and airline selection. In addition, their effects on passengers' selections are significantly different between Korean and foreign airlines.     

A multiple group analysis of the training transfer model: exploring the differences between high and low performers in a Korean insurance company

This study suggests an integrative transfer of training model and examines the influence of pre-training performance on the relationship between work environment variables and transfer-related variables. Structural equation modeling was conducted with data collected from 365 Korean employees of a large general insurance firm. They were all participants in a leadership development program. The results of multi-group analyses revealed that the influence of work environment variables on transfer-related variables was moderated by employees' pre-training performance. The findings of the study imply that a more elaborate training transfer model that considers performance not just as an outcome variable, but also as an antecedent variable is required. Also, it is proposed that different strategies should be applied to promote transfer of training based on the employee's level of pre-training performance.     

Organizational attraction toward a company that adopts a smoke-free policy

The current study investigated Korean smokers’ and non-smokers’ evaluations of an organization implementing a policy which either mandated or recommended that employees quit smoking. Undergraduates (n = 268) were randomly assigned to one of 2 (high vs. low severity of smoke-free policy implementation) × 2 (high vs. low organizational assistance) conditions and indicated their attraction to a hypothetical organization, posing as job applicants. The findings showed that non-smoking individuals’ perception of organizational support was more strongly and positively related to organizational attraction when they were more likely to endorse employers’ right to control employee smoking behaviors. Ex-smokers indicated greater attraction toward the organization when it was described as implementing a high severity policy than a low severity policy. Non-smokers indicated greater attraction toward the organization when it was described as offering a high level of assistance than a low level of assistance for smokers’ cessation efforts. These and other findings concerning individuals’ perception of severity, perception of organizational support, smoking sensitivity, and employer control are presented in detail, and the implications thereof are discussed.     

Limit to improvement: Myth or reality?: Empirical analysis of historical improvement on three technologies influential in the evolution of civilization

The evolution of civilization appears to have primarily resulted from continuous improvement made possible by technological advances. A group of social evolutionists and economists have identified, among others, energy, transport, as well as information and communication to be the three most influential technologies. On the other hand, a number of eminent scholars have cited several forces, natural, physiological, technological, as well as environmental which can place a limit on on-going improvement.The purpose of this paper is to empirically explore the continuous improvement process as well as the limit placed on these three technologies. Using the framework of both connected and disconnected multiple technology S-curves and X-factor, historical improvement data on these three elements have been analyzed. The results of our analysis indicate that improvement in general has continued without limit mainly due to a series of emerging new technologies. These emerging technologies can be either connected or disconnected from the existing mature technologies. Our preliminary analysis shows that much of the past improvement comes from new technologies that on first serious application appear to be substantially superior from earlier technologies. In addition, enormous continuous improvement, which has accompanied both connected and disconnected new technologies appear to have played the critical role in sustaining the evolution of civilization. The paper discusses a number of policy implications and suggests topics for future research.     

Beliefs of and attitudes toward political advertising: An exploratory investigation

The major goals of this study were to identify voters' belief structures about political advertising, develop a scale to measure beliefs, and examine how the identified beliefs are related to overall attitudes toward political advertising. The reliabilities, factor structure, and validity tests indicate that five belief dimensions—information, veracity, cynicism, money politics, and entertainment—have sound and stable properties. The scale demonstrates that voters assess political advertising at the instrumental level (e.g., information, veracity, and entertainment) as well as the institutional level (e.g., cynicism and money politics). The results showed that not all beliefs predicted overall attitudes. Furthermore, the results indicated that political involvement was a significant factor in influencing both beliefs and attitudes. © 2009 Wiley Periodicals, Inc.     

Farmers,Biodiversity and Plant Protection: Developing a Learning Environment for Sustainable Tree Cropping Systems

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.     

Service Orientation: Its Impact on Business Performance in the Medical Service Industry

From the viewpoint of internal marketing, employees who are content in their job may be motivated to satisfy their customers better than ones who are not content. Another relevant premise is that the content employees, because of their work motivation, would eventually help improve the performance of their firm. To verify these relationships, some previous studies looked into the effects of organisational service orientation on employee's satisfaction. But only few of them investigated the mediating effects of variables such as service value and customer orientation for their role in linking service orientation to business performance. This study examines how an organisation's service orientation had an effect on its performance at hospitals. For this purpose, verification of the mediating role of service value perceived by employees as well as the role of customer orientation on the firm's performance was attempted. For this study, a total of 292 usable questionnaires were collected from hospital staffs located in metropolitan cities of Korea. The hypotheses concerning relationships among service orientation, service value, employee satisfaction and customer orientation were verified by covariance structural modelling, using SPSS 10.0 and AMOS 4.0 programs. The result is as follows. First, organisational service orientation had a positive effect on both employee satisfaction and service value perceived by hospital staff. Second, employee satisfaction had a positive impact on service value and customer orientation. Finally, service value as well as employee's customer orientation were found to exert positive influence on the medical firm's performance.     

Employment responses to aggregate and sectoral technology shocks

This paper investigates the responses of sectoral employment in US manufacturing to a technology shock by its type: aggregate or sectoral. In order to distinguish between aggregate and sectoral shocks, we construct independent VAR models for identifying each shock separately: a factor-augmented vector autoregression (FAVAR) for aggregate shocks and a sectoral SVAR for sectoral shocks. Our aggregate model in particular extends the conventional small-scale VAR to the FAVAR framework of Bernanke et al. (2005) so that it can address the potential bias from omitted variables. The main findings are as follows: most industries exhibit negative employment responses to an aggregate technology shock while exhibiting positive responses to a sectoral technology shock. By comparing our FAVAR framework with Chang and Hong’s (2006) small-scale VAR, we show that applying the FAVAR results in significant differences in the estimated responses to an aggregate technology shock. Real rigidities (such as slow diffusion of new technology or frictional labor reallocation), rather than nominal rigidities (such as sticky prices), are crucial in accounting for the cross-industry difference in employment responses. In particular, the slow diffusion of new technology is closely related to the sluggish response of sectoral employment.     

Relationships among consumer vanity,gender, brand sensitivity,brand consciousness and private self‐consciousness

The purpose of this study was to examine relationships among consumer vanity, gender, brand sensitivity, brand consciousness and private self‐consciousness within a context of social comparison theory. The four dimensions of consumer vanity are concern for and positive view of physical appearance and concern for and positive view of achievement. Participants were 400 college students (284 women; 116 men). Participants above the median in three of the four dimensions of vanity (except vanity achievement view) were more sensitive to and more conscious of brand names. Participants above (vs. below) the median in vanity achievement view scored higher on private self‐consciousness. Women scored higher on brand sensitivity, brand consciousness and private self‐consciousness than men. There was a significant correlation between brand sensitivity and brand consciousness. Results support the notion that consumers’ decisions, especially regarding brand names, may be guided by vanity‐related concerns and views.
