Accounting for heterogeneous technologies in the banking industry: a time-varying stochastic frontier model with threshold effects

This paper investigates the existence of heterogeneous technologies in the US commercial banking industry through the nondynamic panel threshold effects estimation technique proposed by Hansen (Econometrica 64:413–430, 1999, Econometrica 68:575–603, 2000a). We employ the total assets as a threshold variable, which is typically considered as a proxy for bank’s size in the banking literature. We modify the threshold effects model to allow for time-varying effects, wherein these are modeled by a time polynomial of degree two as in Cornwell et al. (J Econom 46:185–200, 1990) model. Threshold effects estimation allows us to sort banks into discrete groups based on their size in a structural and consistent manner. We determine seven such distinct technology-groups within which banks are allowed to share the same technology parameters. We provide estimates of individual and group efficiency scores, as well as of those of returns to scale and measures of technological change for each group. The presence of the threshold(s) is tested via bootstrap procedure outlined in Hansen (Econometrica 64:413–430, 1999) and the relationship between bank size and efficiency ratios is investigated.     

When do corporate social responsibility initiatives impact on customer-facing employees? Evidence from India and the Netherlands

The vast majority of the extant literature on corporate social responsibility (CSR) has focused on the macro (firm) level of analysis by examining the linkage between CSR and firm-level outcomes. As such, very few studies have focused on the micro (individual) level of analysis. Against this backdrop, the present study focuses on the individual level of analysis thereby contributing to the emerging psychology of CSR literature, which considers employees' perceptions of their employing organizations' social actions as more important than organizations' objective CSR performance (Rupp, Shao, Thornton and Skarlicki (2013), ‘Applicants’ and Employees’ Reactions to Corporate Social Responsibility: The Moderating Effects of First-Party Justice Perceptions and Moral Identity,’ Personnel Psychology, 66, 895–933). Moreover, the study is one of the first examining the role of context in employee attitudes toward CSR. In particular, it builds on the psychology of CSR (e.g. Rupp et al. 2013) literature to propose a research framework that delineates the moderating effects of satisfaction with payment, satisfaction with the job itself and individualism in the relationship between corporate social performance (CSP) perceptions and customer-facing employees' behavioral outcomes. Data are collected from customer-facing employees in two major organizations in the Netherlands and India. Results suggest a complex interplay between CSP perceptions and the two facets of job satisfaction, and that national context is likely to moderate the contingent effects of CSP perceptions on customer-facing employees' behavioral outcomes.     

The role of international hubs in a fashion retailer's sourcing strategy

The purpose of this paper is to evaluate the role of international hubs in a fashion retailer's sourcing strategy. In order to compete more effectively in a dynamic fashion market, retailers have adopted a low cost, offshore sourcing model to supplying their domestic market. There are three approaches which have been used to implement an offshore sourcing strategy; direct sourcing from the HQ, the use of intermediaries and international hubs. The aims of the research were to understand the motives behind the development of international hubs, identify their stages of development and determine both their strategic and operational role within fashion companies' global strategies. Research was carried out through semi-structured interviews with the heads of 3 international hubs, one buying office and the head of merchandising at the HQ in the UK of a subsidiary of a major UK fashion chain. Results show that hubs evolve from buying offices to multifunctional units, specialising in supplying particular products to the market. Although hubs perform important operational functions, there was little intra hub coordination and the headquarters exerted considerable control over their hubs with regard to overall sourcing strategies.     

Spatial evolution of airport traffic and air transport liberalisation: the case of Greece

This paper explores the evolution of airport passenger traffic in Greece over the period 1978–2006. The country is a member of the European Common Aviation Area, but despite air transport liberalisation, spatial concentration of traffic and asymmetry remain high and have not decreased significantly over time. Greece is still short of traffic generated by low-cost carriers especially outside the main metropolitan airports. The paper argues that further dispersion of traffic could be possible primarily in the mainland if low-cost carriers decide to dynamically enter the Greek market. Potential benefits for regional and tourism development should induce policy makers to work towards this direction.
