Market concentration in the Korean banking industry has markedly increased since the financial crisis of 1997-1998 because of M&As, P&As, and consolidation of banks. With this change, there has been a growing concern over market power in the Korean banking sector. We examine the effects of market concentration on bank efficiency and competition for the period of 1992-2006. Three different indicators of bank inefficiency are used in this study, including X-inefficiency that is derived from the directional technology distance function. The level of competition is measured by both the H-statistic of the Panzar-Rosse model and the level of the net interest margin and its standard deviation. Empirical results indicate that market concentration has not improved bank efficiency through scale economies or scope economies. Instead, recent mergers, acquisitions and consolidation of banks resulted in an increase in inefficiency measured by the three different indicators: X-inefficiency, labor inefficiency and asset inefficiency. While an increase in market share of individual banks improved bank efficiency, an increase in the overall market concentration ratio resulted in lower efficiency. Our study also finds that the Korean banking sector has been monopolistically competitive throughout the sample period except for the crisis period according to the H-statistic. Although an increase in market concentration ratio has not changed the overall level of bank competition, it has a positive significant effect on the level of the average interest margin.

The Korea government has been pursuing various policies to find a new industrial growth engine based on ICT (Industry and Communication Technology). However, ICT industry recently faces a serious crisis due to a lack of fundamental competitiveness and capital and technological gap with other countries. Accordingly, it is necessary for ICT industry to recognize the rapidly changing competitive business environment and to establish appropriate value-based strategies. This paper analyses factors affecting value-based strategy in the Korean ICT industry using 10 years data set. The result shows that the value-based strategy in the Korean ICT companies has a significant influence on their financial performance. In addition, it is confirmed that the competition level in the industry has a significant moderating effect on this relationship. In addition, when the companies are categorized based on performance, it is confirmed that there is a significant difference in competition level and value-based strategy in each categories. The results of this paper are expected to suggest implications for the effective use of balanced value-based strategies in the ICT industry.

This study proposed that a relationship exists between individual emotions and knowledge sharing (KS) intentions in competitive online advice communities. Through statistical analysis of 220 valid questionnaires collected from qualified community members, we found that individuals' intentions to contribute knowledge were enhanced by playfulness and reciprocity, while their intention to seek knowledge from others was facilitated significantly by needs fulfillment, sense of competition, and playfulness. In addition, we found that playfulness was a common factor that affected the intention to seek, as well as to contribute, knowledge. Specifically, playfulness was a highly significant individual emotion that affected both individuals' intention to contribute and seek knowledge, while reciprocity was significant primarily in individuals' intentions to contribute knowledge. Needs fulfillment and sense of competition were significant emotions that affected primarily individuals' intentions to seek knowledge. Interestingly, the factors that affected the intention to seek knowledge were consistent both in all participants and in the high-level fear group. However, in the low-level fear group, playfulness influenced KS intentions.

The increase rate of dentists' competition is very fast at metropolitan areas in South Korea. We compare metropolitan and rural parameters to investigate the relation between competition and revenue variation. The competition and revenue variables of 73 metropolitan and 75 rural areas were calculated from 2010 Census of Service Industry microdata which include non-insurance revenues of dental clinics. Independent sample t-test results showed that the level of competition among dental clinics in metropolitan areas is higher. The lowest and the low ranked revenues are higher in rural areas. The highest and the average revenues are higher in metropolitan areas. But, 25 percentile and median revenues has no significant difference between two areas. Simple log linear regression results showed that the number of clinics could explain the distribution of revenues in both areas better than the density of active dentists and Herfindahl-Hirschman index. In the areas with many clinics have high maximum and average revenues and low minimum revenues. The increasing rate of maximum revenues is higher in metropolitan areas though the decreasing rate of minimum revenues is higher in rural areas. Metropolitan areas have higher Gini coefficients than rural areas, but the increasing rate of Gini coefficients is lower than rural areas. Findings from this study are useful reference when the dentists select the opening areas. One is that the median revenues between metropolitan and rural areas have no significant difference. The other is that the rural areas ensure the more stable and uniform revenues. The results would help to relieve the consumptive competition among dentists and to achieve the distributional efficiency of dental human resources.

Other-regarding preferences (such as trust, reciprocity and altruism) between companies, between consumers and retailers, and between employers and employees are integral elements in determining economic performance. Social trust which is a core element of social capital, especially, is known to reduce transaction costs, help solve collective action problems, and contribute to economic, social, and political development. Therefore, social trust has been given a great deal of attention across an array of academic disciplines for its role in promoting cooperation among individuals and groups, and for its positive influence on economic performance. Most studies describe Korea as a low-trust society than Japan or China. To identify the causes of social trust, this paper focuses on differences of social values (perception on competition and wealth accumulation) in 4 countries (Japan, China, Korea, and United States). Based on World Values Survey data, this paper analyzes effects of the social values on social trust. Social trust was measured by degree to which a respondent thinks that most people can be trusted. Perception on competition was measured by the degree to which a respondent thinks that competition is harmful, and perception on wealth accumulation was done by the degree to which a respondent thinks that wealth can grow so there is enough for everyone. The results showed that social trust was affected by perception on competition and wealth accumulation. A respondent showed higher level of social trust when he (or she) perceived positively competition and wealth accumulation. For enhancing social trust in a country, it is not easy to reduce income inequality and corruption which were reported as causes of social trust by previous studies. Compared to them, social values can be changed more easily by various concrete measures like education and mass-media. Differently from previous studies this paper stresses the concrete measures to enhance social trust in a country.

Purpose - The purpose of this paper is to study strategic trade policies under international process research and development (R&D) competition with or without market leaders for free trade and a subsidy regime and compare the effects of R&D subsidies and export subsidies on the equilibrium levels of firm profit and social welfare. Design/methodology - For the analysis, we use previous work by Haaland and Kind (2008) and construct a differentiated goods duopoly model, wherein two firms compete via quantity in a third-country market for free trade and the subsidy regime. We consider simultaneous-move quantity competition when the two firms choose their quantities simultaneously and sequential-move quantity competition when they choose their quantities sequentially. The results are compared to those of Balboa, Daughety and Reinganum (2004), who studied export subsidies. Findings - The following are the findings. First, the results of firm preference orderings regarding firm position from Dowrick (1986) and Balboa, Daughety and Reinganum (2004) may not hold in our model when the firms' strategies are strategic substitutes under free trade. Second, the preference rankings under Cournot competition for free trade and a subsidy regime are the same as those in the strategic trade policy of export subsidy. Third, except for the cases of too close substitutes and complements, the results of firm and government preferences regarding firm position are different from those of Balboa, Daughety and Reinganum (2004) in that Stackelberg leadership in a subsidy regime is advantageous when the goods are substitutes but is disadvantageous when the goods are complements. Moreover, the equilibrium level of firm profit is the highest in the Cournot-Nash play when the goods are substitutes in a subsidy regime. Fourth, except for the cases of too close substitutes and complements, the results of firms' and their respective governments' trade regime preferences are similar to those of Balboa, Daughety and Reinganum (2004) in that a Stackelberg leader firm and government prefer free trade if the goods are substitutes and prefer a subsidy regime if the goods are complements. Furthermore, a Stackelberg follower firm and government strongly prefer a subsidy regime to free trade. Originality/value - By analyzing the effects of R&D subsidies and export subsidies in international markets, we can find similarities and differences between them in international markets.

This study The study analyzed the effect of the advertisement method of admission at Korea Polytechnic University on the competition rate for entrance to university. A total of 66 questionnaires were analyzed among freshmen and undergraduates at Korea Polytechnic University in Seoul. The first study revealed that the ground promotion (p<.01, ${\beta}=.363$) had an effect on the competition rate, with the ground promotion having a statistical effect on the competition rate and therefore having a significant competitive edge. Second, it was analyzed that the ground promotion and registration rates were correlated to the $p{\times}.01$ level with the. 297 level of media promotion and registration rates. Third, although the motivation for knowing the junior high school records and the Korean Polytechnic University did not significantly affect the registration rates, it was found that there were group differences because the admission patterns were higher than usual on time. This study analyzes the effect of the admission promotion method on the competition rate of the university, identifying the importance of ground advertisement, media promotion to the competition rate and registration rate, and identifying the effectiveness of characteristic factors.
