This study aims to discuss ways to improve the information disclosure system centered on the Freedom of Information Act by analyzing the revision history of the Act and interviewing information disclosure experts. First, the study analyzed the revision history and contents of the Act from its enactment to today. It found that although positive amendments have been made in terms of expanding the right to know, they have been limited to operational aspects, and no amendments have been made to the criteria for determining information subject to disclosure. The interview was organized into three areas: achievements, problems, and improvements of the Act. The analysis was conducted by breaking down the content of each area and organizing it into themes. In conclusion, the study proposed eight recommendations for improvement, including expanding the scope of information disclosure, categorizing the information to be disclosed, securing a procedure for appealing the non-disclosure of information, increasing the effectiveness of the committee, introducing penalties and disciplinary regulations, establishing an Information Disclosure Appeals Tribunal, establishing systematic controls to prevent misuse of the right to request information, and merging the Public Data Act with the Freedom of Information Act.

Purpose - This study analyzes the effect of sellers' dishonesty on various market outcomes such as seller profit, buyer profit, and market welfare, through precisely measuring the level of sellers' information disclosure and its economic impacts. As an explicit observation of sellers' dishonesty is not easy in most other settings, this study is expected to suggest unique and meaningful implications on the effect of sellers' incomplete information disclosure to researchers, managers, and policy makers. Design/methodology/approach - In order to precisely measure the level of sellers' dishonesty under information asymmetry, this study analyzes the data from an incentive-based economic experiment using z-Tree software. This experimental method enables us to focus on the strategic interactions among participants, observe the integrity of seller's information disclosure, and reproduce real market situations. Findings - The analysis of sellers' dishonesty has provided the following important and counterintuitive findings about the reality of buyer-seller interactions under information asymmetry. First, sellers' lies do not affect seller profit even when they are very intensive. Second, sellers' dishonesty negatively affects buyer profit and the entire market welfare. Third, a seller's quality claim has a positive effect on the seller profit only when a seller is being honest. Research implications or Originality - This study analyzes sellers' dishonesty using incentive-based economic experiment using z-Tree software which provides a straightforward examination on dishonest behavior of sellers, that is not readily available with other types of observational or experimental data.

Purpose: This study examines the effect of full information disclosure on seller profit when there exists information asymmetry between sellers and buyers, focusing on the risk averseness of buyers. By investigating the interaction between product quality and perceived risk through online sales data, we attempt to figure out the incentive structure of full information disclosure specifically when buyers are risk-averse, so that we can suggest more feasible information disclosure strategy to sellers. Research design, data and methodology: Our empirical model analyzes the sales data of collectible goods from a major online seller using Poisson regression. In our model, we have specifically considered risk-averseness of buyers by estimating the interaction effect between the product quality and perceived risk on seller profit, aiming for a more precise empirical analysis on sellers' incentive structure of full disclosure. Results: Our empirical analysis strongly supports the effect of interaction between product quality and perceived risk, showing that the incentive for full disclosure is much stronger when product quality is higher, and vice versa. Therefore, sellers are strongly encouraged to voluntarily reveal product weaknesses when their product quality is higher than average, while it is more profitable to hide any product defects when quality claim is lower than average. Conclusions: This study supports the related literature by confirming economic incentives for full disclosure, and also supplements and strengthens previous studies by presenting that the effect of interaction between product quality and perceived risk strongly affects seller profit. Our unique finding supports both mandatory disclosure and voluntary disclosure arguments and presents practical implications to marketing managers by suggesting that seller's incentive for revealing weaknesses depends on the level of seller's product quality.

Objectives : The purpose of this study was to determine whether the published AMI report card could reduce in-patient mortality, 7-day after discharge mortality, and length of stay (LOS). Methods : Interrupted time-series intervention analysis was used to evaluate the impact of the report card for AMI care quality in November 2005 in terms of risk-adjusted in-patient mortality, risk-adjusted 7-day after discharge mortality, and DRGs case-mix LOS using the claim data of Health Insurance Review and Assessment Service. Results : Public disclosure of AMI care quality decreased risk-adjusted in-patient mortality and DRGs case-mix LOS by 0.00050% per month and 0.042 days per month respectively, however there was no effect on risk-adjusted 7-day after discharge mortality. Patterns of effect of public disclosure on AMI outcomes were a fluctuating pattern on risk-adjusted mortalities and a pulse impact for 1 month on DRGs case-mix LOS. Conclusions : We found the public disclosure of AMI care quality had decreasing effects on risk-adjusted in-patient mortality and DRGs case-mix LOS, but the size of the effect was marginal.

Recently, several studies in the field of privacy research suggested counterintuitive phenomenon about previous studies on existing perspectives. They claim that consistency of attitude and behavior does not exist, which is called privacy paradox. This study aims to clarify the relationship between intention to information disclosure and actual behavior based on the privacy paradox perspective. It attempts to explain the causes of privacy paradox phenomenon through the dual process theory being discussed in the field of behavioral economics. The results of empirical analysis are as follows. First, paired t-test analysis between intention to information disclosure and actual behavior was statistically significant. This means the existence of privacy paradox. Second, privacy risk had significant explanatory power to behavioral intention, and privacy trust had significant explanatory power to actual behavior. In conclusion, this study shows that negative belief influences decision making situation controlled by rational thinking whereas positive belief influences actual situations controlled by intuitive thinking.

Purpose - This study attempts to provide a new theoretical perspective on the quality signaling and its impact on a market under information asymmetry, focusing on how the accuracy and the cost of quality signaling affect sellers' and buyers' profit, suggesting appropriate designs of quality signaling methods which mitigates information asymmetry. Design/methodology/approach - In order to examine the effect of quality signaling on strategic interactions within the market, we establish an analytic model where market outcomes are determined by seller's quality claim and price, and buyers are risk-neutral. By investigating this analytic model through relevant game trees, we find the subgame perfect Nash equilibria of the market and predict related market outcomes based on sellers' quality signaling strategy. Findings - Our analytic model shows counterintuitive results that seller profit will be the lowest with inaccurate quality signaling and the highest with no quality signaling, mostly due to the certification cost. Consequently, sellers should proceed with caution if the quality signaling is less than accurate, as it may backfire. We believe that this is due to the fact that the inaccuracy of quality signaling causes some confusion and uncertainty in both sellers and buyers' decision to maximize profit, making it hard for sellers to predict buyers' behavior. Research implications or Originality - Although the sources and types of quality signaling errors have been investigated in the literature, there has not been satisfactory understanding regarding how inaccuracy of quality certification affects specific market outcomes. We expect that our theoretical model would provide important implications on how to utilize quality signaling to solve adverse selection issues in markets under information asymmetry.

In the recent years, Gov.2.0, which strengthens not only a claim for freedom of information but also sharing public information, became a new paradigm of government operations. In line with the paradigm the Korean government promotes the Gov.3.0 policy. This study exams the freedom of information system, which expends its roles and responsibilities for enhancing the usage of public information in the Gov.3.0 era. Furthermore, it analyzes the system's usability from the perspective of users. The freedom of information system is the fundamental portal for all the public information's disclosure and usage. Without providing the solution for problems of the system, the Korean government's Gov3.0 policy cannot succeed. Also, Park Geun-hye Government's Gov.3.0 initiatives which consists of tasks, such as reinforcing freedom of information, immediate releasing original documents, and expending public access to information, should be done through the freedom of information system. The importance of the system is increasingly heavy. It is not only the simple online contact point for public information, but also a public sphere for sharing public raw data and for implementing the Gov.3.0 vision. However, the current system still does not slove it problems. This study analyzes the system's problems in terms of usability and sustainability. As a result, it provides three alternative strategies for the freedom of information system, including 'personnel and financial support expansion', 'strengthening user-friendly operating' and 'establishing long-term strategies for system improvement.

This study compared and analyzed the efficiency of the research results of the convergence research project operated by the National Science and Technology Research Council and the general research project carried out by the Government-funded research institute and proposed measures to enhance the efficiency of the operation and management of convergence research. Research data were collected from 21 government-funded research institutes through an information disclosure claim and DEA analysis was conducted for efficiency assessment. The SCI papers of convergence research showed high efficiency, and the patent registration and technology transfer sector showed high efficiency of general research projects. This indicates that convergence research projects for securing lead and original technologies are highly efficient, but their performance is low due to lack of participation by businesses in terms of the utilization of derived technologies, and more companies' participation and opportunities are needed for practical use of convergence research results. Through the analysis of efficiency of convergence research project performance, this study provided policy and guidance for R&D planning for rational investment of limited manpower and research costs. Further, future research on identifying efficiency is proposed depending on the type of technology subject to convergence research as a method for managing convergence research.
