The purposes of this article is to analyse how market competition of credit card company affect price(interest rate) and survival length of card users. This paper uses individual account data from a large Korean credit card company during the periods from 2002 to 2006. The findings of our study are as follows. First, market competition of credit card company have a negative effect with interest rate of credit card. Second, market competition of credit card company have a affirmative effect with survival length. Finally, The effect of Increasing delinquency rate due to price increase is smaller than decreasing delinquency rate due to extending survival length.

Investment decisions are one of the most fundamental issues in financial management. This study aims to determine the factors that affect investment decisions in the energy industry and to contribute to the companies in this industry to develop strategic policies. The System GMM analyzes were carried out using the data of companies registered on the stock exchange for the period 2000-2015. The findings showed that industrial competition and firm size were important factors influencing the investment decisions of firms in the energy industry. The findings indicated a nonlinear relationship between industrial competition and the rate of investment in the energy sector. Depending on the firm's size, the effect of industrial competitiveness on investment varies. Smaller businesses are more impacted by the level of competition than larger ones. The investment rate decreases depending on the increase in cash holding level and firm risk. When the subgroups in the energy industry are examined, it is determined that they reveal some differences in terms of financial structure. A higher investment rate results from a higher retained earnings ratio. The investment rate of firms falls as a company's risk level and sales revenue variability increase.

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.

This paper has shown the trend of competition positioning of 26 Korean ports in 1994, 1999, and 2003 by using BCG matrix which consists of relative market shares, growth rate of cargo handling, and also growth rate and CCR and BCC efficiency scores with scale efficiency scores in the vertical and horizontal axes. The empirical main results are as follows. First, Incheon Port, Pyungtag Port, Gwangyang Port, Busan Port, Pohang Port and Woolsan Port have shown their competitive positioning in terms of market share and growth rate. Second, Pyungtag Port, Wando Port, Tongyoung Port, Gohyun Port, Samcheog Port, and Okgae Port have their competitive positioning in terms of growth rate and scale efficiency scores. The main policy implication of this paper is to emphasize that BCG matrix method using in this paper can give seaport manager the basic information for planning the future port management for enhancing the competitive positioning among Korean seaports.

Objectives: According to the Korea Education Development Institute, the college admission quota is expected to exceed the number of high school graduates, leading to an anticipated expansion in the gap between them. This paper aims to conduct an empirical analysis of the variables previously studied, with a specific focus on the admission competition rate for the department of dental hygiene. Methods: The research methodology is the multiple linear regression analysis. The research data contains the structured data from academy information, and the web-based unstructured data collected over the past 3 years. Results: After conducting the analysis, it was newly discovered that the university's online recognition and its location in the metropolitan area were statistically significant factors influencing the admission competition rate for the department of dental hygiene. Conclusions: The findings of this study are expected to be helpful in formulating admission strategies for universities to attract new students and identifying the factors that influence student attraction.

Purpose: This study compares and analyzes the design drawing changes that occur during the design process between hospital design competition and the final detailed design. Based on this, factors that can reduce the rate of changes in drawings are derived. The purpose is to provide basic data to lessen the rate of the changes in the process of architecture design and can be reflected in the design competition guidelines. Methods: In this study, cases of hospitals are selected which are built in 5 recent years. Then compare and analyze the drawings which was drawn in the process from submission of competition to final design. After investigating the design changes that occur after the design competition, analyze the fixed-elements which are the main causes of design changes. Fixed-elements can be narrow down into few architecture-factors such as vertical-core, shafts, public-corridor, HAVC, and mechanical/electrical spaces. Results: Result of the rate of changes in each selected hospital floors can be sorted into variable-elements and fixed-elements which tells that the higher the rate of changes of the fixed-elements, the higher the rate of changes of the variable-elements. Implications: In other words, it can be said as the lower the change rates of the fixed-element, lower changes in whole design changes which represents that the greater the efficiency can be shown in the design process.

State highway agencies (SHAs) typically apply a competitive procurement procedure to select contractors for their design-bid-build projects. Since the level of competition affects construction bid prices and project outcomes, the Federal Highway Agency (FHWA) suggests SHAs seek ways to improve competition among contractors continuously. However, they rarely conduct an empirical assessment of the current competition level necessary to identify room for improvement. Besides the number of bidders on a project, other factors such as winning or losing rates among the contractors in previous projects can also indicate the degree of competition; only a few contractors may have won the majority of the projects in a specific region. However, few studies have investigated such factors. This paper proposes a network analysis-based approach to evaluating contractor competition levels of highway projects using historical bid tabulation data. The proposed method provides insights into overall competition levels, the determination of competitive contractors, and winning rate distribution among contractors.

공공투자사업에서는 최저가낙찰제, 턴키 제도, 대안입찰제 등 다양한 방식이 사용되고 있다. 최근 가격경쟁을 통한 효율성 제고를 주목적으로 하는 최저가낙찰제가 확대되어 시행되고 있다. 본 논문은 우리나라 입 낙찰 제도의 현황과 특징을 파악하고, 대형 공공투자사업에 주로 적용되는 최저가 낙찰제, 턴키 대안 입찰제도하에서의 가격 경쟁효과가 직접적으로 드러나는 낙찰률을 비교 분석하는 것에 의미가 있다. 각 입찰제도의 성과는 경쟁의 행태에 달려 있음을 고려하여 경쟁률과 낙찰률을 중심으로 여러 입찰제도의 입 낙찰 현황을 분석하였다. 1,000억원 이상 사업의 경우 최저가낙찰제하에서 평균 입찰참여자 수는 33.75명, 평균 낙찰률은 61.18%로 나타나, 턴키 대안 입찰제의 평균 입찰참여자 수 2.94명, 평균 낙찰률 90.20%와 큰 차이를 보였다. 최저가낙찰제의 경우 규모의 차이를 고려한다 하더라도 낙찰률이 현저히 낮으며, 경쟁의 정도가 심한 것을 확인할 수 있다. 이러한 낙찰률의 차이는 근본적으로 제도의 차이로 해석할 수 있으며, 경쟁의 차이로도 일부 해석할 수 있다. 민간투자사업의 경우, 평균 입찰참여자 수는 1.88명이며, 평균 낙찰률은 90%에 이르고 있어 경쟁 활성화를 통해 효율성을 제고할 여지가 있음을 제시하였다.
