Nonparametric Evaluation of Economies of Scope in the Context of Technical Efficiency: The Case of Rice and Vegetable Farms in Korea 下载免费PDF全文
This paper provides a nonparametric evaluation of economies of scope in the context of technical efficiency allowing for non‐convexity, with an application to Korean rice and vegetable farms. Relying on non‐parametric‐free disposal hull and data envelopment analysis approaches and input–output data for rice and vegetable farms from the Korea Farm Household Economy Survey data collected in 2007, this article examines technical inefficiency and its decomposition under non‐convexity and convexity. Empirical measures of technical inefficiency and its decomposition results are provided, with a focus on a component of technical inefficiency associated with economies of scope (i.e. diversification benefits) under non‐convexity in production technology. The decomposition measures of technical inefficiency include pure technical inefficiency, size inefficiency and diversification inefficiency. The results provide empirical evidence supporting size‐dependent diversification strategies, where benefits of diversification are larger for small farms on average compared to those of large farms. 相似文献

Given the recent ethics scandals in the United States, there has been a renewed focus on understanding the antecedents to
ethical decision-making in the research literature. Since ethical norms and standards of behavior are not universally consistent,
an individual’s choice of referent may exert a large influence on his/her ethical decision-making. This study used a social
identity theory lens to empirically examine the relative influence of the macro- and micro-level variables of national culture
and peers on an individual’s intention to behave ethically. Our sample consisted of respondents from Germany, Italy, and Japan.
The results indicated that both national culture and peers were found to act as significant referents in ethical decision-making
dilemmas. Although peers exerted a much stronger influence on an individual’s ethical decision-making, the impact of peers
varied depending on the national culture levels of individualism and power distance.

ABSTRACT The paper deals with determinants in the cross-cultural setting of service encounters in tourism. The first part of the paper describes the theoretically expected influence of culture (cultural values) on the perception of expected and received service qualities. Based on a review of the literature cultural values are hypothesized to intervene in the formation of expectations and the perception of received service quality (satisfaction) across specific service quality related choice and/or decision and evaluation processes. Cases in point are particular dimensions of service quality encountered in tourism destinations, events and accommodation settings. The second part of the paper explores the usefulness and also the limitations of alternate cultural constructs found in the literature and used in the analysis of tourist's service quality judgements. Finally in part three the cultural distance is suggested as a useful potential proxy for the influence of cultural values in tourism applications and is discussed alongside other cultural constructs traditionally employed in tourism analyses. 相似文献

Abstract This study investigated the effects of subculture, marginality, and perceived discrimination on use of selected public outdoor recreation areas. The assimilation perspective from the sociology literature provided theoretical guidance for the study. These concepts were treated as different types of social distance (cultural distance, socioeconomic distance, and intergroup distance). Each was hypothesized to affect the use of outdoor recreation areas. Data for this analysis came from telephone interviews conducted with 1057 households in Maricopa and Gila counties in Arizona. The analysis was conducted using a subsample of respondents of Mexican ancestry. The results support the socioeconomic, or marginality, hypothesis. There was less support for the subcultural, or ethnicity, hypothesis. There was no support for the perceived discrimination hypothesis. Research implications and recommendations are discussed. 相似文献

AbstractStrong growth need is essential if an employee is to be motivated to complete complex and challenging jobs. It is important for organizations to attract employees with high growth need strength and help them achieve positive outcomes. However, limited research has been conducted to examine the mechanism underlying growth need strength’s positive effect on employee outcomes. Based on hope theory, we hypothesized that hope mediates the effect of growth need strength on job performance and affective commitment by transforming employees’ general desire for personal growth into goal-related cognitive thinking, comprising both ‘will’ and ‘ways’. We further hypothesized the moderating effect of transformational leadership, and the joint moderating effect of transformational leadership and individual power distance on the relationship between growth need strength and hope. We tested our hypotheses with data from a sample of 265 subordinate–supervisor dyads from China. Data analysis results supported the mediating role of hope. We found that growth need strength has a stronger effect on hope when transformational leadership is higher, and this effect is the strongest when both transformational leadership and individual power distance are simultaneously higher. The implications of these findings for human resource management research and practice are discussed. 相似文献

This article uses travel distance to segment rural tourists in a tourist destination in the U.S. Midwest. A distance decay pattern was identified, with more than half of the respondents traveling from a location within 200 miles of the destination. The differences in the socio‐demographic, trip‐related characteristics, and destination activities of these tourists were examined across distinct distance segments. Among other findings, the study revealed that tourists from within a 50‐mile radius participated in most of the activities, and those traveling between 200 and 600 miles made up the majority of business travelers. These two segments also had a higher participation rate in the recreational activities than did the other distance segments. The findings of the study show that simple variables such as distance travel remain viable for destinations, particularly those in the rural area, to understand the tourists for segmentation purpose. 相似文献

We develop a specification test and a sequence of model selection procedures for non-nested, overlapping, and nested models based on the second Hansen-Jagannathan distance, which requires a good asset pricing model to not only have small pricing errors but also be arbitrage free. Our methods have reasonably good finite sample performances and are more powerful than existing ones in detecting misspecified models with small pricing errors but are not arbitrage-free and in differentiating models that have similar pricing errors of a given set of test assets. Using the Fama and French size and book-to-market portfolios, we reach dramatically different conclusions on model performances based on our approach and existing methods. 相似文献

The purpose of this research is to enhance knowledge about service recovery by investigating the feelings of psychological distance in the relationship between customers' perceptions of service recovery efforts of the perceived justice dimensions (distributive, procedural, and interactional justice) and attitudinal responses such as satisfaction with service recovery effort and trust in the firm. The results of structural equation modelling analyses suggested that consumers who had positive justice perceptions were likely to exhibit positive attitudinal responses. Consequently, the positive attitudinal responses generated positive word-of-mouth intention about their experiences and encouraged them to continue the service. 相似文献
