Purpose - As the U.S.-China trade war has become considerably worse, the Chinese government is considering applying non-tariff barriers to trade, especially local contents rule. The main purpose of this research is to check whether it is suitable for Korean investors to invest in the current Chinese capital market. Design/methodology - In order to check the stability of the recent Chinese capital market, we investigated the behavior of foreign equity investment (including Korean equity investment) in the Chinese capital market after China announced the Shanghai-Hong Kong Stock Connect (SH-HK Connect). In this paper, we researched whether international portfolio investment would or would not contribute to an increase the volatility of an emerging market's stock market (Chinese capital market) when foreign investors make investment decisions based on the objective of short-term gains by rushing into countries whose markets are booming and fleeing from countries whose markets are falling. Findings - The empirical results indicate that foreign investors show strong, negative feedback trading behavior with regard to the stock index of the Shanghai Stock Exchange (SSE), and when the performance of foreign investors in the Chinese stock market was fairly good. Also, we found evidence that the behavior of foreign investors significantly decreased volatility in SSE stock returns. Consequently, the SH-HK Connect brought on a win-win effect for both the Chinese capital market and foreign investors. Originality/value - It appeared that the Chinese capital market was very suitable for Korean investors after the China's declaration of the SH-HK Connect. However, the win-win effect was brought on by the Chinese government's aggressive capital control but the capital controls could possibly cause financial turmoil in the Chinese capital market. Therefore, Chinese reform in industrial structure and the financial sector should keep pace with suitable capital control policies.

Korea's GIS market has been proliferating since the 1990s, but still its scale and the structure require overall rearrangements. Recently as the needs and initiatives from central and local governments go stronger to drive 'u-City(ubiquitous City)' developments, there are much more demand of spatial information from sectors like city management, construction, environment and so on. Through the merge between GIS and the advanced Information and Telecommunication Technology, the introduction of new Ubiquitous IT is swiftly changing GIS market environments, so the GIS industry is to be prepared for this trend. The pioneering developments of Ubiquitous-related GIS technologies are expected to highly boost spatial data and related industries, and the pre-occupancy of those technologies in the world would enable the expansion of overseas export market. In the context of these epoch-making chances, by looking into the actual status of GIS industry, this study is to investigate the actual accomplishments to foster the GIS industry through Korea's National GIS Master Plan. Thereby, impending issues will be discussed to provide useful problem-solving suggestions.

Mainland China area has been a long-term, major trade rival and partner of Taiwan, accounting for more than 40% of Taiwan's total annual trade exports, and so Sino-US trade friction is expected to have a significant impact on Taiwan's economy in the future. This study focuses on major bad news of Sino-US trade frictions and how it generates short-term shocks for Taiwan's equity market and fear sentiment. It further explores the mutual interpretation relationship between price changes such as VIX, Taiwan's stock market index, and the VIX ETF to identify which factors have information leadership as leading indicators. The study period covers 750 trading days from 2017/1/3 to 2020/1/31. This study finds that, when a policy news is announced, the stock market index falls significantly, the change in the trading price (net value) of the VIX ETF rises significantly, and the overprice rate significantly drops, but VIX does not, showing that fear sentiment exists in the Taiwan's market. The net value of the VIX ETF shows an information advantage as a leading indicator. This study suggests that, when the world's two largest economies clash over trade, the impact on Taiwan's equity market is inevitable, and that short-term fear effects will arise.

Purpose: This study aims to explore an ability to time market-wide investor sentiment of mutual fund managers in an emerging market. Research design, data, and methodology: Based on data of Thai mutual fund market over the period of 2000-2019, our sample includes 283 equity funds, consisting of 204 bank-related funds and 79 nonbank-related funds. We perform our regression analyses at the aggregate and portfolio levels. Results: Under the non-normal distribution of return, we find different behaviors between the best- and worst-performing funds in an ability to time market-wide investor sentiment in Thailand, which is dissimilar to the findings in the U.S. Bottom fund managers act as sentiment hedgers, who decrease (increase) an exposure of investment portfolios when the investor sentiment is high (low). Oppositely, top fund managers are likely to chase investor sentiment. Conclusion: We find that only the worst-performing fund managers, especially for bank-related funds are able to time the market-wide investor sentiment. An advantage of gaining information from their bank's clients is a key success. A competition in the mutual fund industry, an ability to predict fundamentals, and financial literacy are possible reasons to explain the main findings found in this study.

U. S. commercial landings of wild salmon have remained relatively stable for the past 5 years, averaging 300,000 MT. While the same period, U. S. imports of fresh salmon have increased over ten fold from 1.8 to over 19 million pounds. Over 70 percent of the new supplies of fresh salmon come from Norway. Norway exports to the United States were negligible in 1980 and 1981. However, U. S. imported 1,768 M. T. in 1983, 3,896 M. T. in 1984, and 6,272 M. T. in 1985. Over the past 5 years, import price of fresh wild salmon from Canada has declined steadily from ＄2.58 per pound to ＄1.25 per pound in 1985, while those from Norway had remained unchanged, ranging from ＄3.28 to ＄3.45 over the same period. Norway's cultured salmon entered the United States in 1985 at about ＄3.35/1b., roughly triple the price of Canadian fresh wild salmon imports. U. S. apparent consumption of fresh and frozen salmon has sharply increased from 50,000 MT in 1981 to 92,000 MT in 1985, up 86 percent over the five years. Annual per capita consumption has increased steadily from 0.47 pounds in 1981 to 0.85 pounds in 1985. The estimated demand models show that the annual wholesale price of fresh salmon in the U. S. market would be declined by increase in supplies and would be raised by increase in the U. S. GNP. The empirical results in this study show that wholesale price of fresh salmon in 1990 would remain unchanged at the 1985 level, under the following condition: 1) Norwegian production of Atlantic fresh salmon would reach 80,000 MT (176 million pounds by 1990) 2) Imports of Norwegian Atlantic fresh salmon would keep the same percentage (21%) of Norwegian productions in 1990 3) Imports from other countries and U. S. domestic production would increase and maintain the same level of 25% of U. S. total supplies in 1990 4) U. S. GNP would increase by ＄200 billion annually, slightly less than in the past years.

In this paper, we develop a dynamic structural model based on a dynamic supergame and measure market power for the Dallas-Forth Worth fluid milk market in the U.S. In particular, we compare the conduct parameter estimates from a static model with that from the dynamic model and illustrate bias in the market-power measure in a static model. And we also analyze the cyclical behavior of firm conduct. We find that the conduct parameter in a static model underestimates true market power if firms' behaviors are posited by a dynamic oligopoly game. We also verify that firm conduct in the Dallas-Forth Worth fluid milk market is countercyclical against demand shocks and expected future cost shocks. Our results indicate that the firms' conduct in the Dallas-Forth Worth fluid milk market is consistent with what dynamic oligopoly models predict. This implies that the firms consider not only the contemporary reactions of the other firms' but also future market competition. Therefore, the measurement of market power requires the specification of fully dynamic pricing relationship.

This paper attempted to suggest that Korean corporations are to infuse their TQC practice with strategic component. The general concept of TQC was reviewed. Then the nature of TQC systems in the two coon tries. U.S. and Japan. were analyzed. QC circles and the rank and file members of factories are the driving force of Japanese TQC whereas TQC in U. S. tends to be specialist-oriented in practice. Japanese market strategies were also discussed in order to examine the possible connection of Japanese TQC with Japanese corporations' competition strategies.
