The price structure of housing market varies depending upon market price policy rather than low or high price policy because of IMF. The object of this study is to develop an analysis system for analyzing housing market and its demand. The analysis system consists of four major categories: macro index analysis, market decision analysis, housing market analysis, and consumer analysis. We model each category by using a variety of techniques such as generalized linear model, categorical analysis, bubble analysis, drill-down analysis, price sensitivity meter analysis, optimum price index analysis, profit index measurement analysis, correspondence analysis, conjoint analysis, and multidimensional scaling analysis. Seoul apartment data is analyzed to demonstrate the practical usefulness of the system.

Purpose: The aim of this study is to explore the dynamic linkage between conditional stock market volatility and macroeconomic uncertainty of Bangladesh. Research design, data, and methodology: This study uses monthly data covering the time period from January 2005 to December 2018. A comprehensive set of macroeconomic variables, namely industrial production index (IP), consumer price index (CPI), broad money supply (M2), 91-day treasury bill rate (TB), treasury bond yield (GB), exchange rate (EX), inflow of foreign remittance (RT) and stock market index of DSEX are used for analysis. Symmetric and asymmetric univariate GARCH family of models and multivariate VAR model, along with block exogeneity and impulse response functions, are implemented on conditional volatility series to discover the possible interactions and causal relations between macroeconomic forces and stock return. Results: The analysis of the study exhibits time-varying volatility and volatility persistence in all the variables of interest. Moreover, the asymmetric effect is found significant in the stock return and most of the growth series of macroeconomic fundamentals. Results from the multivariate VAR model indicate that only short-term interest rate significantly influence the stock market volatility, while conditional stock return volatility is significant in explaining the volatility of industrial production, inflation, and treasury bill rate. Conclusion: The findings suggest an increasing interdependence between the money market and equity market as well as the macroeconomic fundamentals of Bangladesh.

본 연구는 국내 주요 수입 수산물- 냉동명태, 냉동고등어, 냉동참치 그리고 냉동어란- 시장을 대상으로, 각 수출국이 차지하는 시장점유율에 따라, FTA 발효가 환율전가도에 미친 영향이 어떻게 달라지는 지 살펴 보았다. 이에 더하여 각 수출국이 차지하는 시장점유율이 원화표시 수출가격 환율전가도에 미친 영향 뿐만 아니라, 수출국들의 가격경쟁구조에 미친 영향 역시 살펴보았다. 이를 위해, 본 연구는 2010년 1월부터 2019년 12월까지 각 수출국의 원화표시 수산물 수출가격과 각 수산물 수입시장에서 개별 수출국별 교차환율의 월별 자료를 이용하여, 최대우도법(Maximum Likelihood)을 바탕으로, 각 수출국의 원화표시 수출가격함수를 추정하였다. 분석 결과, FTA 발효가 환율전가도에 미친 영향은 수출국인 FTA 회원국이 차지하는 시장점유율과 높은 상관관계에 있음을 발견하였다. 하지만 수출국이 차지하는 시장점유율과 원화표시 수출가격 환율전가도 그리고 다른 경쟁국의 수출가격에 미친 영향 사이에서는 뚜렷한 관계를 파악하기 어려웠다. 본 연구 결과를 통해, 국내 수산업자들은 국내 주요 수산물 수입시장에서 각 수출국들이 차지하는 시장점유율에 따른 환율전가도 차이 및 FTA 발효가 환율전가도에 미친 영향의 차이 그리고 수출국들 사이의 가격경쟁구조를 이해하는 데 중요한 자료가 될 것이라 예상된다. 뿐만 아니라, 각 수산물 수입시장에서 차지하는 시장점유율에 따라, 각 수출국별로 FTA 발효 이후, 환율이 국내 수산업에 미치는 영향에 대응할 수 있는 방안에 관해 생각해 보는 데 도움이 될 것이라 사료된다.

기후변화는 현재 사용되고 있는 지표수 및 지하수 등의 담수자원 외에도 새로운 수자원을 확보해야할 필요성을 증가시켰다. 해수담수화 시장은 이러한 변화에 따라서 매년 급증하고 있는 상황이며, 이에 발맞추어 2007년 해수담수화 플랜트 사업단이 국내에서 출범하였다. 2014년에 종료된 해수담수화플랜트 사업단은 증발식 해수담수화 기술에 치우친 국내 기술을 역삼투방식 해수담수화 기술로 선회할 수 있도록 이끌었다. 현재 세계 최고의 역삼투방식 해수담수화 기술 에너지 효율성은 약 $3.5kWh/m^3$ 전후로 조사된다. 기장 플랜트의 수준은 $3.8{\sim}4.0kWh/m^3$ 수준으로 비록 세계 최고 수준에는 미치지 못하나, 선두권이라 하기에는 부족함이 없는 것으로 사료된다. 한편, 세계 역삼투방식 해수담수화 기술은 평준화 수준에 이른 것으로 사료되며, 에너지 저감을 위해 새로운 기술을 개발하고자 경쟁중이다. 미래 해수담수 시장에서 경쟁할 것으로 예상되는 기술로 정삼투공정, 막증발법 등이 있으며, 이를 위해 국내에서도 정역삼투 융합공정 개발, 막증발법 및 얍력지연삼투등의 기술개발을 진행중에 있다. 이를 통하여 국내 기술수준을 $2.5kWh/m^3$까지 낮출 것으로 기대된다.

Using the ARDL approach, this study examined the impact of macro factors on Vietnam's stock market in the short and long run from 2010 to 2021. The State Bank of Vietnam and the International Monetary Fund provided time series data for this study. Research results show that in the long run, money supply and exchange rate respectively affect the stock market. The money supply had a positive effect on the VN-Index, while the exchange rate showed the opposite effect. However, the study did not find a relationship between world oil price and interest rates on VN-Index in the long run. On the other hand, in the short term, there are relationships between variables; specifically, interest rates and exchange rates have a negative impact on the VN-Index, while the world oil price and the fluctuation of money supply M2 of the previous one and two months showed an impact in the same direction on this index. The differences in the regression results on the impact of exchange rate and oil price on the VN-Index compared to previous studies come from the characteristics of Vietnam's stock market, with the large capitalization of companies in the oil and gas sector, and the structure of Vietnam's economy with export heavily depends on FDI sector.

This study identified types of online retail internationalization in the fast-fashion context and proposed driving factors of retailers' choices in online-based market entry following the logic of the Uppsala model and the eclectic theory. In particular, this study proposes three types of online-based internationalization: 1) entering a host market with a physical store first, and then expanding with an online store, 2) entering a foreign market with an online store, then expanding to physical stores, and 3) entering only with an online business. In addition, this study investigated the causal factors, ownership-specific and location advantages, that influence the choice of the type of developmental process of online-based internationalization. To develop theoretical and managerial insights into the issue researched, this study employed a qualitative research design involving case studies of three European fast-fashion retailers, H&M, TOPSHOP, and ASOS. This study suggested that fast-fashion retailers that enter a host market with high ownership-specific advantages are likely to choose to enter the market with physical stores and then expand with online stores. On the other hand, when faced with uncertainties attributable to low ownership-specific or location advantages, fast-fashion retailers are likely to choose to enter with an online store first and then expand with physical stores as conditions change. Consequently, this study provides a better understanding for fast-fashion retailers who are willing to expand their businesses to foreign markets via online stores.
