Microstructure-based manipulation: Strategic behavior and performance of spoofing traders

We examine how investors strategically spoof the stock market by placing orders with little chance of being executed, but which mislead other traders into thinking there is an imbalance in the order book. Using the complete intraday order and trade data of the Korea Exchange (KRX) in a custom data set identifying individual accounts, we find that investors strategically placed spoofing orders which, given the KRX's order-disclosure rule at the time, created the impression of a substantial order book imbalance, with the intent to manipulate subsequent prices. This manipulation, which made use of specific features of the market microstructure, differs from previously studied forms of manipulation based on information or transactions. Roughly half of the spoofing orders were placed in conjunction with day trading. Stocks targeted for manipulation had higher return volatility, lower market capitalization, lower price level, and lower managerial transparency. We also find that spoofing traders achieved substantial extra profits. The frequency of spoofing orders decreased drastically after the KRX altered its order-disclosure rule.     

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.     

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.     

The privatization of Korea’s Incheon International Airport

This study looks at the possible effects of the planned privatization of Incheon International Airport, Korea. To accomplish this, it uses a Delphi analysis involving nearly 50 experts to assess six possible scenarios that, for example, look at airport strategy and planning, financial, operations and approach facilities, and fees.     

International reserves and swap lines: Substitutes or complements?

Developing Asia experienced a sharp surge in foreign currency reserves prior to the 2008–9 crisis. The global crisis has been associated with an unprecedented rise of swap agreements between central banks of larger economies and their counterparts in smaller economies. We explore whether such swap lines can reduce the need for reserve accumulation. The evidence suggests that there is only a limited scope for swaps to substitute for reserves. The selectivity of the swap lines indicates that only countries with significant trade and financial linkages can expect access to such ad hoc arrangements, on a case by case basis. Moral hazard concerns suggest that the applicability of these arrangements will remain limited. However, deepening swap agreements and regional reserve pooling arrangements may weaken the precautionary motive for reserve accumulation.     

A Taxonomy of Industries Based on Knowledge Flow Structure

With the advent of the knowledge-based economy, the inter-industrial flow of technological knowledge is reckoned as the principal determinant of national competitiveness. The mode of knowledge flows, however, is intractably complex. Taking it as a network, this paper aims at providing an inductive taxonomy of industries based on the knowledge flow structure and thus identifying the user-supplier relationship among industries in terms of knowledge diffusion. Some proxy indexes are developed first to measure the knowledge flows, then the interactive mechanism among industries is investigated by the network analysis and eventually a taxonomy of industries is presented according to the characteristics of respective industries. The taxonomic approach highlights the importance of inter-industrial knowledge management system that facilitates knowledge flows across industries based on the idiosyncratic features of respective industries.
