Short-term forecasting of Japanese tourist inflow to South Korea using Google trends data

We utilize the Internet search data from Google Trends to provide short-term forecasts for the inflow of Japanese tourists to South Korea. We construct the Google variable in a systematic way by combining keywords to minimize mean squared or mean absolute forecasting errors. We augment the Google variable to the standard time-series forecasting models and compare their forecasting accuracies. We find that Google-augmented models perform much better than the standard time-series models in terms of short-term forecasting accuracy. In particular, Google models show better out-of-sample forecasting performance than in-sample forecasting.     

Structural effects of cognitive and affective reponses to web advertisements,website and brand attitudes,and purchase intentions: The case of casual-dining restaurants

This study investigates the structural relationships among responses to website advertisements, website attitudes, brand attitudes, and purchase intentions in the case of web advertisements for casual-dining restaurants. Responses toward advertising (Rad) factors were categorized as cognitive responses and affective responses. The SEM model in LISREL was used to examine the interrelationships among the proposed hypothesized constructs. Several empirical results were obtained. First, Rad had a positive effect on website attitudes. Second, website attitudes had a positive effect on brand attitudes. Third, brand attitudes had a positive effect on purchase intentions. Finally, some discussion and implications of the study are provided.     

Effect of diversification on firm performance: Application of the entropy measure

This study investigated the effects of diversification on firm performance in the restaurant industry. In prior studies, the theoretical rationales and empirical results appeared to contradict each other. These contradictory results may be due to factors such as industry-specific characteristics or a linear understanding of the relationship between diversification strategies and firm performance. Thus, this study suggested a non-linear hypothesis based on the costs and benefits of diversification strategies with businesses categorized based on their level of diversification. The results of this study showed that restaurant firms do not benefit from a low level of related diversification. This study also found that when restaurant firms are involved in both related and unrelated businesses, the optimal mixed ratio of diversification is approximately half and half. More detailed results, as well as academic and practical implications, are discussed in this paper.     

Regulatory Uncertainty and Financial Contagion: Evidence from the Hybrid Capital Securities Market

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids.     

Audit Committees and Managerial Influence on Audit Quality: ‘Voluntary’ versus ‘Mandatory’ Approach to Corporate Governance

This study provides empirical evidence on how managerial influence to reduce audit quality is moderated by a combination of the audit committee (AC) form and compliance with AC best practice guidelines. There is a negative association between managerial ownership and audit fees; however, the association becomes positive when a voluntary AC follows best practices. Furthermore, the results are robust to the exclusion of industries with large frequency in the sample, the consideration of Korean business groups and recessionary times. The results of this study imply that a voluntary approach to corporate governance, which encourages companies to follow best practice guidelines in the form and composition of the AC, is more effective in controlling management than a mandatory approach. This study contributes to policy making aimed at improving AC effectiveness.     

Financial Integration in Asset and Liability Holdings in East Asia

In this article, we examine the evolution of intra-East Asian financial integration from 2001 to 2013. Most existing studies on this topic look primarily at asset holdings; we examine liability holdings as well. Using the International Monetary Fund’s Coordinated Portfolio Investment Survey data for equities, long-term debt, and short-term debt, our analysis generally supports the conventional wisdom that East Asian countries are more financially integrated with global financial centers than they are with each other. This is true for both asset holdings and liabilities and is confirmed by an econometric analysis based on financial gravity equations. However, the gap between global integration and regional integration has narrowed for asset holdings over time but not for liability holdings. The results of additional econometric analysis indicate that diversification of liability holdings can mitigate financial instability due to global financial shocks. More precisely, diversification was associated with smaller exchange rate depreciation during the quantitative easing taper tantrum of 2013. These results point to a possible benefit from strengthening regional financial integration. Deeper regional integration would reduce dependence on global financial markets for funding and hence vulnerability to global shocks.     

Corruption,soundness of the banking sector,and economic growth: A cross-country study

This paper explores the impact of corruption on both the banking sector and economic growth; we determine the impact using 76 macroeconomic data from various countries over the period 2002–2004. The results of various cross-sectional regressions provide substantial evidence that corruption significantly aggravates the problems with bad loans in the banking sector. In this study, we also find some evidence of a new channel through which corruption lowers economic growth: Corruption distorts the allocation of bank funds from normal projects to bad projects, which decreases the quality of private investments, hence it decreases economic growth.     

Lopsided inclusion: The impact of multi-employer bargaining and class-based unionism on non-regular employment in South Korea

This study examines the impact of multi-employer bargaining on non-regular workers across different unions and types of non-regular employment. Using national representative survey data from South Korea, I find that multi-employer bargaining increases the likelihood that a workplace union would address a pay increase for non-regular workers when the union was affiliated with a confederation espousing class-based as opposed to business-unionism. However, such a relationship was weaker for temporary agency workers and subcontractors than for direct-hire fixed-term workers. This mechanism is further illustrated through a second round of data collection and analysis, namely in-depth interviews. I identify two factors that characterize the class-based confederation: (1) centralized pressure from the union and (2) activists and their identity work. Altogether, these results further an understanding of how the identities of national union confederations can influence local representatives’ approach to representing non-regular workers and how those influences are manifested through workplace-level collective bargaining.
