Migration decisions under ambiguity: Migration distance effects revisited

There is ample evidence that distance has a strong negative effect on migration. Despite its significance in migration decisions, scholars rarely explore the migration distance effect deeper than the first level of interpretation derived from the simple neoclassical theory of migration. This study revisits the migration distance effect in the spirit of Knightian distinction between risk and uncertainty. To this end, this study attempts to construct estimates of the risk premium migrants are willing to pay to avoid the risk associated with migration distance. The results show that the magnitude of the distance effect is not rationalized by risk aversion in the Arrow–Pratt sense (Arrow, 1965, The theory of risk aversion, Yrjo Jahnssonin Saatio, Helsinki, Finland, 90; Pratt, 1964, Econometrica, 32, 122). In particular, the risk premium demanded by distant rural residents is unjustifiably higher compared with that of those living closer to urban areas in their migration decisions. The results suggest that the migration distance effect is analogous to the equity home bias puzzle and the Ellsberg paradox in that the assumption of subjective expected utility can lead to seemingly irrational human behaviors. Some of the findings in this study shed light on the role of subjective aspects such as perception, confidence, and pessimism in migration decisions, which have been neglected in the literature.     

Cost structure and productivity growth of the Taiwanese international tourist hotels

This study investigates the cost structure and economic implications of the Taiwanese international tourist hotel industry. A multi-product translog cost function with three inputs and three outputs is estimated using seemingly unrelated regression estimation and three-stage least squares. A balanced panel dataset consisting of 47 international tourist hotels in Taiwan over the period 1997–2001 was obtained from Taiwanese Tourism Bureau and used to estimate the cost function. The results show that both scale and scope economies exist in the Taiwanese international tourist hotel industry. In addition, productivity growth is positive over the study period. Managerial and policy implications for the Taiwanese international tourist hotel industry are also discussed.     

Revenue implication of auction value in <Emphasis Type="Italic">k</Emphasis>-price sealed-bid auctions: An experimental study

In this paper, we show that in a heterogeneous bidding community with predominantly risk-seeking bidders, third-price sealed-bid auctions yield higher revenue for the seller than first-price sealed-bid auctions when the auction value is low. Conversely, when the value of the auction is high, first-price sealed-bid auctions yield higher revenue for the seller than third-price sealed-bid auctions. Existing theoretical findings for a homogeneous group of risk-seeking individuals imply that third-price sealed-bid auctions should generate higher revenues for the seller than first-price sealed-bid auctions. Our results for low-value auctions agree but our results for high-value auctions do not agree with the existing findings. We discuss the implications of this discrepancy as a function of the shift in goal orientation from a win-focus to a value-focus as the value of the auction increases.

Auditors' Responses to Workload Imbalance and the Impact on Audit Quality*

Using detailed data for fieldwork hours and audit hours by rank from audit engagements in Korea, we examine whether audits conducted under workload imbalance, proxied by busy‐season audits, impair audit quality, and how auditors adjust staff assignments for busy‐season audits. We generally find that busy‐season audits are associated with lower audit quality, and that audit firms reduce the involvement of senior auditors during busy‐season audits. In addition, the greater the involvement of senior auditors and junior auditors, the lesser the deterioration in audit quality. Finally, although there is no increase in interim audits in response to workload imbalance during busy seasons, increasing interim audits can mitigate the negative impact of busy‐season audits on audit quality. Our results are relevant to auditors and regulators, who have expressed concerns about the adverse effects of workload imbalance on audit quality.     

Critical success factors for mutual collaboration with suppliers in IT outsourcing industry: a case study of a top IT outsourcing company in Korea

ABSTRACT

Nowadays, information technology (IT) outsourcing companies face enduring demands to reduce cost while increasing productivity. This pressure leads many IT outsourcing companies to rely on outsourcing arrangements with IT personnel suppliers. In order to maximise efficiency, outsourcing companies have focused on fostering high-performing suppliers through improved collaboration and mutual relations. However, it is very difficult to advance to a long-term partnership using the existing outsourcing process because of insufficient collaboration between IT outsourcing companies and their suppliers. Based on collaboration perspective of supply chain management (SCM), this study identifies the critical success factors for collaborative strategic partnerships and presents an evaluation framework for assessing and managing suppliers. We have developed an organisational process model for Supplier relationship management (SRM)-based collaboration which includes some of the key constructs from the previous studies and interviews with the IT outsourcing industry people. In this study, we will identify four types of strategic suppliers and suggest approaches for improving collaborative relationship between an IT outsourcing company and its partner companies. In addition, to validate the feasibility of the proposed model, we applied it to a well-known Korean IT outsourcing company ‘A’.     

Motivations and Use Context in Mobile Tourism Shopping: Applying Contingency and Task–Technology Fit Theories

Mobile tourism shopping is an emerging market, but there is little theoretically based research on the topic. This study investigates the impact of motivations (value, enjoyment, time saving and mobility) on consumer satisfaction by applying contingency and task–technology fit theories in the mobile tourism shopping context. The results show that value and enjoyment have significant effects on satisfaction. Use context is found to have a full mediating role between time saving and satisfaction as well as between mobility and satisfaction. This study offers theoretical and practical contributions to the tourism literature and mobile tourism industry. Copyright © 2013 John Wiley & Sons, Ltd.     

When does an employee not help coworkers? The effect of leader–member exchange on employee envy and organizational citizenship behavior

Using a sample of 233 front-line hotel employees, we examined leader–member exchange (LMX), envy, and organizational citizenship behavior (OCB). The results from path analysis support the research model that employees who have a relatively poor working relationship with their supervisor (i.e., low-quality LMX relationship) were more likely to show higher levels of envy than employees who have relatively closer working relationships with the same supervisor (i.e., high-quality LMX relationship). Ultimately, higher levels of envy decreased employee voluntary helping behavior (i.e., organizational citizenship behavior, OCB) toward coworkers. This finding suggests that employees perceiving a poor working relationship with their supervisor committed less voluntary helping behavior toward coworkers than their counterparts. Implications for managers and suggestions for future research are discussed.     

Forest transition in South Korea: Reality, path and drivers

While forest transition (FT) in South Korea began in 1955, when forest cover was only 35% of national land area, significant increases in both forest cover and growing stock really occurred in the early 1970s. Using reconstructed historical records, we empirically demonstrate that (1) FT in South Korea was mainly accomplished by the recovery of degraded, non-stocked forest; and (2) one-dimensional FT analysis using forest area alone has severe limitations in diagnosing meaningful changes in forest sustainability. The key driver of FT in South Korea was the government-led reforestation policy. The comprehensive reforestation plans, started in 1973, not only provided economic incentives to the general public by establishing clear quantifiable goals, they also promoted inter-agency cooperation and coordination, especially between the energy and forest sectors, to replace firewood with fossil fuels. These government-led efforts, accompanied by rural-urban migration, brought an increase in stocked forest area and a complementary rising average growing stock level. The case of South Korea shows that FTs can be cultivated in a relatively short period of time by a central authority, even with imperfect governance and low economic development.     

Vertical Specialization and Trade Growth in Northeast Asia

As the global economy has become further integrated, the international production chain has become more sophisticated, with diversified stages of production located in different countries. Economic theorists have argued that the fragmentation of the global production chain is partly attributable to the high growth in international trade over the past several decades. In this study, we examine vertical specialization in China, Japan and Korea, and its contribution to these nations' trade. Using a multilevel model, it is illustrated that vertical specialization has encouraged increases in trade among all three countries. In particular, China's outcome is remarkable considering how recently it became a member of the WTO.     

Valuing traceability of imported beef in Korea: an experimental auction approach*

The major objective of this study is to estimate Korean food shoppers’ willingness to pay (WTP) for imported beef with traceability. We use an experimental elicitation method, the random nth price auction, to identify consumers’ valuation for traceable imported beef. We also analyse the effect of different types of information on these valuations. Results indicate that consumers are generally willing to pay a 39 per cent premium for the traceable imported beef over similar beef without traceability. Results also suggest that in contrast to the insignificant effect of positive information, negative and two‐sided information about traceability significantly reduces WTP.
