Consumer ethnocentrism: A test of antecedents and moderators

This article identifies theoretical antecedents of consumer ethnocentricity and the effect ethnocentricity has on evaluations toward importing products. Hypotheses pertaining to the relationship between the identified antecedents and consumer ethnocentricity are developed based on an extensive review of the ethnocentrism and country-of-origin literatures. Also identified are factors moderating the effect of ethnocentric tendencies on consumers’ attitudes toward importing products. The hypotheses are subjected to an empirical test using data collected in Korea.

Financial market models with Lévy processes and time-varying volatility

Asset management and pricing models require the proper modeling of the return distribution of financial assets. While the return distribution used in the traditional theories of asset pricing and portfolio selection is the normal distribution, numerous studies that have investigated the empirical behavior of asset returns in financial markets throughout the world reject the hypothesis that asset return distributions are normally distribution. Alternative models for describing return distributions have been proposed since the 1960s, with the strongest empirical and theoretical support being provided for the family of stable distributions (with the normal distribution being a special case of this distribution). Since the turn of the century, specific forms of the stable distribution have been proposed and tested that better fit the observed behavior of historical return distributions. More specifically, subclasses of the tempered stable distribution have been proposed. In this paper, we propose one such subclass of the tempered stable distribution which we refer to as the “KR distribution”. We empirically test this distribution as well as two other recently proposed subclasses of the tempered stable distribution: the Carr–Geman–Madan–Yor (CGMY) distribution and the modified tempered stable (MTS) distribution. The advantage of the KR distribution over the other two distributions is that it has more flexible tail parameters. For these three subclasses of the tempered stable distribution, which are infinitely divisible and have exponential moments for some neighborhood of zero, we generate the exponential Lévy market models induced from them. We then construct a new GARCH model with the infinitely divisible distributed innovation and three subclasses of that GARCH model that incorporates three observed properties of asset returns: volatility clustering, fat tails, and skewness. We formulate the algorithm to find the risk-neutral return processes for those GARCH models using the “change of measure” for the tempered stable distributions. To compare the performance of those exponential Lévy models and the GARCH models, we report the results of the parameters estimated for the S&P 500 index and investigate the out-of-sample forecasting performance for those GARCH models for the S&P 500 option prices.     

Pregnancy outcomes for medicaid patients in mandatory managed care: The Pennsylvania HealthChoices program

A number of states have adopted mandatory managed care to provide health services to Medicaid patients, raising concerns that the care provided may be of lower quality than care provided under traditional fee‐for‐service arrangements. In this article, we study the effect of Pennsylvania's mandatory managed care program, HealthChoices, on health outcomes and the cost of care for pregnant Medicaid patients. Using difference‐in‐differences, we find evidence that the adoption of managed care resulted in fewer preventable complications, particularly for more severely ill mothers, but no general reduction in costs except in the highest decile of the cost distribution.     

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.     

An Equilibrium Theory of Wage and Employment Cyclicality by Gender and by Industry

This paper presents an equilibrium theory that accounts for how cyclical patterns of employment and real wages vary between genders and across industries. Workers' self-selection of industrial sectors, gender differences in comparative advantage among sectors, sector-nonneutral shocks, and resulting mobility of workers across sectors play the key roles in explaining wage and employment cyclicality by gender and by industry. Numerical simulations demonstrate that reasonable parameter values exist under which the current model accords with several stylized facts. These parameter values are characterized most importantly by men's comparative advantage in the sector subject to larger cyclical demand shocks.     

Factors affecting trust between Korean IT firms and their Chinese counterparts

Trust is important in that it facilitates relational exchanges by permitting partners to transcend short-run inequities or risks to concentrate on long-term profits or gains. This study investigates what factors affect the trust between distribution-channel members, principally those between Korean IT firms and their exporting partners in China. We suggest that factors affecting trust include reputation, size, expertise, length of the relationship, communication, and satisfaction with previous outcomes of conflict episodes. Data were collected through a survey of 128 Korean IT firms, which have export-transaction relationships with Chinese buyers. The data strongly support the research hypotheses. As hypothesized, the results of data analysis show that reputation, communication, and satisfaction with previous outcomes tend to enhance trust. Additionally, we noticed that trust seems to decrease as the experience of conflict episodes increases.     

Welfare implications of international financial integration

Focusing on technology spillover from foreign direct investment (FDI) inflows, this paper investigates the welfare implications of financial integration. Calibrations of a neoclassical growth model with international technology diffusion show that when technology catch-up due to FDI inflows is considered, the welfare gains from financial integration substantially increase, which contrasts with the small gains from additional, capital-accumulation effects of financial integration. The estimates suggest that by further enhancing financial integration, emerging Asian economies, such as the People's Republic of China (PRC) and the largest four Association of Southeast Asian Nations (ASEAN) countries, will experience substantial welfare gains.     

Residents' Perceptions of the Impact of Cultural Tourism on Urban Development: The Case of Gwangju,Korea

Cultural tourism constitutes an alternative strategy of sustainable urban development for improving quality of life. The main objective of this type of tourism is to transform regions characterized by cultural resources into ideal places for vacation, residence or business. In this study residents' perceptions of cultural tourism were examined in a case study of Gwangju, Korea. It was found that the majority of the respondents were aware of the importance of cultural tourism and that they argued that it could contribute to urban development. The findings also suggest that there is a strong relationship between the respondents' characteristics and their perceptions of the impact of cultural tourism on urban development.
