Economics at the Antitrust Division 2016–2017: Healthcare,Nuclear Waste,and Agriculture

This year the Antitrust Division of the U.S. Department of Justice litigated an unprecedented number of cases. Two mergers, Anthem with Cigna and Aetna with Humana, threatened to dramatically alter the face of commercial health insurance. The Anthem case raised questions of how to evaluate a claim that competition costs billions annually in potential medical cost savings. The Aetna case raised questions of how commercial insurers compete against the public programs—specifically Medicare. The Division also litigated numerous other civil matters including a proposed merger of nuclear waste disposal facilities. In that case, economists had to explore the scope and bounds of competition within a variety of regulatory regimes. And, in a merger of two new technologies that improve the efficiency of planting seeds, the emerging nature of the market led to interesting variations in the analysis. This overview of the economic issues in these particular cases is intended to provide insights into the challenges of enforcing antitrust law and the way in which economic analysis in particular is used to address those challenges.     

Independent boards and innovation

Much research has suggested that independent boards of directors are more effective in reducing agency costs and improving firm governance. How they influence innovation is less clear. Relying on regulatory changes, we show that firms that transition to independent boards focus on more crowded and familiar areas of technology. They patent and claim more and receive more total future citations to their patents. However, the citation increase comes mainly from incremental patents in the middle of the citation distribution; the numbers of uncited and highly cited patents—arguably associated with riskier innovation strategies—do not change significantly.     

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.     

Asymmetric trade protection leading not to productivity but to export share change

This article revisits a classical theme in economics, that is, the relationship between trade protection and economic performance, with an improved treatment of the endogeneity of tariffs and with consideration of alternative performance criteria. This paper also considers the effects of asymmetric protection, such as higher tariffs on consumer goods and lower tariffs on producer goods. Using sectoral data on Korean manufacturing during the period from 1967 to 1993, this study finds that the effect of trade protection by tariff tends to show up not in terms of total factor productivity but in terms of revealed comparative advantage and export shares of sectors. Such an effect tends to be greater in consumer goods, which are the main targets of promotion by higher tariffs. This study verifies the potentially positive role of tariffs under certain conditions, especially under discipline from world markets.     

Exploring customers’ store loyalty using the means-end chain approach

The study is aimed at revealing the relationships in terms of customer store loyalty by using means-end chains (MEC) analysis, in order to examine the linkages between department stores’ service attributes, involvement, satisfaction and loyalty each of which the customer regards as important. In the study, customer involvement, satisfaction and service quality are connotations that are strongly linked with the customer store loyalty, with service quality being the element to which the platinum tier customers attach the most importance. Data are gathered for a MEC analysis by interviewing 34 platinum tier customers of department stores individually. The results reveal that platinum tier customers are department store customers with a relatively high degree of involvement which is likely to have a positive impact on both core and peripheral service quality, satisfaction toward store loyalty. Although there are numerous studies in the literature that use the means-end chain model to examine customer value within the realm of consumer behavior, few studies discuss platinum tier customers’ store loyalty which is a phenomenon currently receiving a great deal of interest. In contrast to prior research, three connotations are integrated in the study to represent the content and structure of stores’ loyalty attributes for MEC analysis which can offer a different perspective and better understanding for developing highly targeted marketing strategies.     

Visitor Books and Guest-generated Discourses of Hospitality: The Case of the Hanok

This study analyzes visitor book entries as cultural repositories of guest-generated hospitality discourses to understand how guests articulate/narrativize hospitality. Inquiry into visitor book entries offers insight into ways in which tourists render people and place intelligible. Utilizing textual analysis, this study examines discursive entries contained within visitor books displayed at a traditional South Korean hanok guesthouse/commercial home. The findings indicate that tourists' entries could be classified into three emergent categories: Structural Esthetics, Emotions/Affective State, and Inter-personal Engagement. Guests' entries indicated that there was an appreciation for the display of traditional architecture, which facilitated sentiments of relaxation, contentment, tranquility, and homeliness. The hanok is thus regarded as a therapeutic landscape in which positive emotions are nurtured. Guests' entries also showcased evidence of genuine and personalized exchanges with hosts. This study points to the need for further theorizations on the role of indigenous knowledge in informing the performance and reception of hospitality.     

The impact of tour quality and tourist satisfaction on tourist loyalty: The case of Chinese tourists in Korea

This study examines the causal relationship between tourist expectations, tourist motivations, tour quality, tourist satisfaction, tourist complaints and tourist loyalty of Chinese tourists in the Republic of Korea using path analysis. It was found that tourist expectations have a negative effect on the perceived experiential quality of the tour, yet tourist motivation has a positive effect on the perceived tour quality. In turn, the perceived tour quality has a positive effect on tourist satisfaction. Similarly there is an inverse relationship between satisfaction and tourist complaints, and a positive relationship exists between satisfaction and loyalty. Equally, the higher is the number of complaints, the lower are the loyalty levels. These results will provide potential guidelines for inbound tour agents who plan to attract Chinese tourists to Korea and enable them to formulate appropriate strategies. This study also seeks to contribute to conceptual and policy formation by understanding the determinants of tourist satisfaction and loyalty.     

Asymmetric transmission between factory and wholesale prices in fiberboard market in Korea

This paper extends the estimation of price relationships in wood processing and empirical assessment of asymmetric price transmission by incorporating time lags in both explanatory and dependent variables. Each of the models developed and estimated in this article reveals the existence of asymmetric price transmission between factory and wholesale prices of fiberboard in Korea. Estimation results indicate that wholesalers earn additional profits by exploiting price fluctuations in the markets. The empirical findings in this study suggest the potential for lower wholesale prices of fiberboard with more competition in wholesale marketing.     

Free Trade Areas in East Asia: Discriminatory or Non‐discriminatory?

The debates on regional trade arrangements in East Asia focus on whether the RTAs can be net trade creating or diverting, and whether they impede multilateral trade liberalisation or not. This paper attempts to answer these questions by quantitatively estimating the economic impact of possible East Asian free trade areas based on a bilateral gravity model, and evaluating the main characteristics of the proposed FTAs. We find that the trade creation effect expected from the proposed East Asian FTAs such as a China‐Japan‐Korea or an ASEAN plus three (China, Japan, Korea) FTA will be significant enough to overwhelm the trade diversion effect. We also judge that East Asian FTAs will likely be a building block for a global free trade.
