CEO Ethical Leadership, Ethical Climate, Climate Strength, and Collective Organizational Citizenship Behavior

In spite of an increasing number of studies on ethical climate, little is known about the antecedents of ethical climate and the moderators of the relationship between ethical climate and work outcomes. The present study conducted firm-level analyses regarding the relationship between chief executive officer (CEO) ethical leadership and ethical climate, and the moderating effect of climate strength (i.e., agreement in climate perceptions) on the relationship between ethical climate and collective organizational citizenship behavior (OCB). Self-report data were collected from 223 CEOs and 6,021 employees in South Korea. The results supported all study hypotheses. As predicted, CEOs?? self-rated ethical leadership was positively associated with employees?? aggregated perceptions of the ethical climate of the firm. The relationship between ethical climate and firm-level collective OCB was moderated by climate strength. More specifically, the relationships between ethical climate and interpersonally directed collective OCB and between ethical climate and organizationally directed collective OCB were more pronounced when climate strength was high than when it was low. Theoretical and practical implications of these findings are addressed herein.

This article introduces a historical view of fintech and discusses the ecosystem of the fintech sector. We then discuss various fintech business models and investment types. This article illustrates the use of real options for fintech investment decisions. Finally, technical and managerial challenges for both fintech startups and traditional financial institutions are discussed.     

Strategic Choice and Performance in Late Movers: Influence of the Top Management Team's External Ties

This work examines how the strategic choice and performance of late movers are influenced by the top management team's external ties, inside and outside the firm's industry. Using a multiyear sample of firms from the computer industry, we found that intra-industry trade-association ties of top managers led to the adoption of a resource-imitation strategy by late movers while extra-industry importation and professional-association ties led to the adoption of a resource-substitution strategy. We also found that trade association ties had a negative effect on the performance of late movers using resource-substitution, while top managers' service on other firms' boards had a positive influence on the performance of those firms. Our findings not only confirm the importance of the role of fit in strategy and performance, but they also highlight the importance of the management and control of boundary-spanning activities.     

Optimal Exit Costs of Foreign Direct Investment

This paper examines the optimal policy on exit costs of foreign direct investment for a host country considering the impact of varying income level and host country’s risk aversion against volatile FDI flows. Based on a dynamic model about the impact of the exit costs on FDI inflows and capital formation, we demonstrate that a host country should determine the exit cost considering two counterbalancing factors, that is, facilitating higher FDI inflows and reducing volatility of FDI inflows. When a host country is less vulnerable to volatility with inelastic risk aversion against FDI volatility, it is optimal for the host country with a negative income shock to take a more aggressive approach to induce FDI inflows by lowering exit costs. However, if the host country is more vulnerable to volatility with elastic risk aversion, the host country is advised to take a conservative approach by increasing exit costs to reduce FDI volatility. These findings, supported by the OECD data on 42 countries’ exits costs, implicate that developing countries are recommended to lower exit costs to induce higher FDI inflows when they are not highly vulnerable to volatility shocks.     

Executive Bonus Target Ratcheting: Evidence from the New Executive Compensation Disclosure Rules

This study investigates whether firms revise executive bonus compensation targets based on past performance. Studies in this area suffer from a lack of detailed information related to executive performance targets. Using mandatory disclosures of executive compensation information under the U.S. Securities and Exchange Commission's new disclosure rules, this study provides the first large‐sample evidence of bonus target ratcheting. There are three major findings: (i) executive bonus targets ratchet and they ratchet asymmetrically; (ii) the degree of target ratcheting and ratcheting asymmetry vary with executive equity incentives and investment opportunities; and (iii) performance relative to bonus target is serially correlated.     

FAST SWAPTION PRICING IN GAUSSIAN TERM STRUCTURE MODELS

We propose a fast and accurate numerical method for pricing European swaptions in multifactor Gaussian term structure models. Our method can be used to accelerate the calibration of such models to the volatility surface. The pricing of an interest rate option in such a model involves evaluating a multidimensional integral of the payoff of the claim on a domain where the payoff is positive. In our method, we approximate the exercise boundary of the state space by a hyperplane tangent to the maximum probability point on the boundary and simplify the multidimensional integration into an analytical form. The maximum probability point can be determined using the gradient descent method. We demonstrate that our method is superior to previous methods by comparing the results to the price obtained by numerical integration.     

Hospitality and tourism marketing: recent developments in research and future directions

This study reviews marketing research published in selected hospitality and tourism journals for the period of 2002–2003. The review includes summaries of research topics, industry applications, and methods of study design and data analyses. Significant topical research trends are identified and discussed to raise issues for future research. Included also are the industry-specific current trends and issues that dictate immediate research attention. The gaps between hospitality and tourism marketing research and industry's research needs are addressed to encourage additional research on neglected topics. The study concludes with general suggestions for future hospitality and tourism marketing research.     

Communication and Monetary Policy

Recent trends toward greater central bank independence and theadoption of formal inflation targeting by several countrieshave served to emphasize the importance of communication policy.In this paper, we explore some of the economic effects of publicinformation that arise whenever public information serves thedual role of conveying fundamental information as well as servingas a focal point for better coordination. More precise publicinformation is a double-edged tool. While it is very effectivein influencing actions through coordination, sometimes it canbe too effective, and coordinate actions away from fundamentals.     

Forecasting customer switching intention in mobile service: An exploratory study of predictive factors in mobile number portability

This study investigates switching barriers under the mobile number portability (MNP) in the U.S. mobile market. The structural equation modeling analysis is used to evaluate the causal model, and confirmatory factor analysis is performed to examine the reliability and validity of the measurement model. The logistic regression is used to investigate the effect of demographics on switching decision. The findings indicate that customer satisfactions, switching barriers, and demographics significantly affect subscribers' intent to switch. Among them, switching barriers had the most significant influence, which raises a question of the effectiveness of MNP. The MNP in the U.S. mobile market is intended to play an important role in lowering switching costs which can increase the level competition among providers. The findings, however, imply that subscribers still perceive switching barrier high, discouraging them from switching carriers.
