The government has the duty to prevent abuses of monopoly and promote competition in order to maximize consumer welfare. In order to promote competition we have to address the asymmetry in the information as possible and to ensure consumer choice. The subsidy seems to reduce the burden on the consumer service charges and handset prices but it virtually distort the market through price discrimination. The government caused the principal-agent problem by avoiding their appropriate role to prevent distortion of the mobile telecom market. The money used as subsidy could be transferred to down the price of cell phone and charges and it would be a benefit to consumers. Separate notice of subsidies by Mobile Communications Terminal Distribution Structure Improvement Act is a developed policy but it was too late. It, the market price close to that from perfect competition structure, is plausible, ultimately.
Purpose - This study is to investigate the direct and moderating effect of intangible variable like economic freedom to facilitating factors on FDI(foreign direct investment) inflows and the difference of facilitating factors by the stage of economic development. Design/methodology/approach - Fixed-effect panel regression analysis with 19-year macro economic data from 2000 to 2019 including economic freedom index from Fraser Institute in 13 developed and 15 developing countries was used. Research implications or Originality - In analysis of direct effect of 5 sectors in economic freedom, the influence of economic freedom was shown weaker than other macro economic factors on FDI inflows, which indicates that actual development of economic factors are more important. The effect of economic freedom on FDI inflows at the stage of economic development differed. In developed countries, human capital, GDP, export, free trade and regulation affected FDI inflows in decreasing order, as did human capital, GDP, consumption expenditure, export, investment expenditure, government expenditure, free trade and sound money in developing countries. In analysis of moderating effect of economic freedom, a domestic and international market size, a flexible labor market which can provide a cheaper good human resources and government expenditures for improving social infrastructure under free economic environment facilitated FDI inflows. However, the statistical significance of moderating effect on export was not shown, which indicates that economic freedom policy itself without actual improvement of exports could not attract FDI inflows.
The governments of almost countries have the rules and procedures that the purchasing entities have to follow, in order to ensure that the best value for money spent is obtained in procuring goods and services. However, there are often some of important problems in their rules relating to government procurement. Namely, almost countries have a variety of discriminatory regulations for foreign suppliers in the government procurement laws with the object of national security, economic welfare, and protection of domestic market from international competition. For this reason, several advanced countries had reached the Plurilateral Agreement on Government Procurement during Tokyo Round(1973-1979) and Uruguay Round(1986-1994). However, the provisions of two agreements do not apply to all products made by the government but only to those made by purchasing entities specified by each member country in its list in the Appendix. Accordingly, the size of goods and services purchased from foreign suppliers were comparatively not large. As we know well, the United States have spent a large amount of money from federal and state government budget. But the portion of procurement from foreign suppliers is still small, compared with the portion of procurement from domestic suppliers. The main reason are that U.S. has applied for long time the so-called Buy American Act to government procurement positively and maintained many kinds of other domestic regulations which have discriminatory provisions for foreign goods and foreign suppliers. On the recognition of these points, this thesis deals with the Buy American Act and other U.S. domestic laws, regional and bilateral, and plurilateral agreements including WTO Agreement on Government Procurement. As a result, the author found that there are several concerns and problems in the U.S. regulations relating to government procurement. It include the provisions on priority procurement of U.S.-produced products, local contents requirements, set-aside procurement from small business, and exclusion of preferential procurement from the developing countries.
This research aims to inquiry the present state of online game industry and related laws and investigate the nature and feature of the web-board game policy through the case of web-board game operation in China. We reviewed China local literature of online mobile game industry and inspected foreign entry, copyright protection, safety audit, distribution, and shop in China laws related to online game. We examined the game operation of the most famous 'Bianfeng' game company among China web-board game and considered how the charge and exchange for game money is made at issue. The result was revealed that money exchange was made in twilight zone neither legal nor illegal due to dual feature of China law. It is an ambiguous judgment that did not take a strong prohibition. However, we found that minium regulation was gone just in case social trouble happened. The result of this research will expect to help Korea regulation authorities and game company that have plans to enter China market the guideline for game operation policy.
The purpose of this study is to measure the pizza purchasing behavioral characteristics of respondents and importances of factors affecting pizza purchase, to estimate the effects of attributes on choice of pizza restaurant, and to predict probability of selecting a particular pizza restaurant. The questionnaire consisted of two parts: The paired experimental profiles, purchasing behavior and importances of factors affecting pizza purchase. This study generated profiles of 16 hypothetical pizza restaurants based on seven attributes. The profiles comprised 16 discrete sets of variables, each of which had two levels. For this study, researcher randomly selected 150 university students as respondents. Twenty one students did not complete the survey instrument, resulting in a final sample size of 129. All estimations were carried out using frequencies, $X^2$, independent samples t-test, phreg procedure of SAS package. The results were as followed: Some purchasing behavioral characteristics and importances of factors affecting pizza purchase were significantly different by purchase frequency. Based on the estimated models developed for the two purchase frequency groups, the Chi-square statistics were significant at p<0.001. The parameter estimate for late delivery time with frequently purchase frequency group was highest, and the parameter estimate for price with frequently purchase frequency group was highest. The pizza restaurants that charged 20,000 won, offered 100% discount on eleventh pizza, promised to deliver pizza in 20 min, usually delivered the pizza as promised, offered 2 or more types of pizza crust, delivered steaming hot pizza, and did not offer a money-back guarantee which was favored by each of the two purchase frequency groups. The results from this study suggested that there was an opportunity to increase market share and profit by improving operations so that customers can receive discount and money-back guarantee simultaneously, and by reducing price, delivery time.
The concept, means, value chain, the persons concerned and possible issues of game item trading in cash are analyzed in this study.

All estimations were carried out using frequency, correlation, phreg procedure of SAS package. The results were as followed Based on the estimated model, the -2LL(B) statistic for a model with all explanatory variables was 5585.761 and the Chi-square statistic is 134.786 with 7 df (p<0.001). At p<0.001, we would reject the null hypothesis that the attributes do not influence choice. The parameter estimate for price was highest, followed by late delivery time, promised delivery time, money-back guarantee, discount, pizza variety, and pizza temperature. The result from this study suggested that there was an opportunity to increase market share and profit by improving operations so that customers receive discount and money-back guarantee simultaneously, and by reducing price, delivery time.

The purpose of this study is to investigate how to make a proper investment in ICO in the market. Previously, companies used to borrow money from banks or to obtain investments from venture capital (VC) and angel investors, but now ICOs are used as a new type of funding and financing model. The ICO sells the tokens or coins created on the blockchain openly online to raise the necessary funds, and provides the market value by paying the tokens or coins as much as the investment amount. According to this study, the limitations of the ICO market are (1) difficulties in evaluating the company, (2) uncertainties in investments, (3) lack of legal safeguards, and (4) measures to secure corporate stability after recruitment. At present, there is no way to cope with this systematically since the ICO is not protected in the legal framework. Nevertheless, we investigated the ways to make proper investment in the existing ICO market. In investing in ICO, investors should (1) consider investment methods and profitability, and (2) verify and judge investment fraud through various channels (ex. Homepage, composition team profile, etc.) and make investments based on this. This study will contribute to the formation of a healthy ICO market by understanding the newly emerged ICO market and studying the considerations when investing in it, thereby contributing to the right investor training and reducing the mass production of consumer damages caused by fraud. The limitation of this study is that the domestic ICO has not yet been examined in the legal framework, so further research is needed when policy changes occur in the future.
