Purpose - The volume and valence of online word-of-mouth(eWOM) have become an important part of the retailer's market success for a wide range of products. This study aims to investigate how the growth of eWOM has generated the product's final financial outcomes in the introductory period influences. Research design, data, and methodology - This study uses weekly box office performance for 117 movies released in the South Korea from July 2015 to June 2016 using Korean Film Council(KOFIC) database. 292,371 posted online review messages were collected from NAVER movie review bulletin board. Using regression analysis, we test whether eWOM incurred during the opening week is valuable to explain the last of box office performance. Three major eWOM metrics were considered after controlling for the major distributional factors. Results - Results support that major eWOM variables play a significant role in box-office outcome prediction. Especially, the growth rate of the positive eWOM volume has a significant effect on the growth potential in sales. Conclusions - The findings highlight that the speed of eWOM growth has an informational value to understand the market reaction to a new product beyond valence and volume. Movie distributors need to take positive online eWOM growth into account to make optimal screen allocation decisions after release.

The purpose of this study is to measure the trade insurance's macroeconomic effects by analyzing the causality between major economic variables(GDP per capita, market interest rate, inflation, unemployment rate, exchange rate) and trade insurance variable. I conducted empirical analyses using First-difference GMM(Generalized Method of Moments), System GMM and Panel-VAR Model, with panel data from 11 countries(Korea, United States, Japan, BRICs, Indonesia, Singapore, Hong Kong, Vietnam) between 1992 and 2011. There are several important findings. Above all, Trade insurance is positively and significantly related to GDP. This results show that trade insurance serves to increase economic growth. In other words, trade insurance leads to economic growth by helping increase GDP per capita. Especially, trade insurance negatively related to unemployment rate, it is for sure that trade insurance contribute to decrease unemployment rate. And trade insurance helps control of inflation. It is also confirmed that trade insurance contributes to price stability, which in turn serves to stabilize the overall economy. And this research finds as uncertainty in the market increases, seen it as increase of exchange rate, increasing trade insurance supply is stabilize the exchange rate.

To see the implication of trade policy in endogeneous growth model, we introduce trade protection that takes the form of an import tariff and represents one plus the rate of protection provided to industry sector. We showed that considering goodness of fit of regression model, we can see that the empirical evidence is strongly in favor of the character of trade policies as the instrument spurring economic growth. As for import tariff, we see that 1% increase in the rate of tariff that protect domestic market causes the rate of growth to increase by 0.87%. An import tariff to final product significantly spurs product development and faster growth come as a result. But, we should note that the effects of trade policy are muted by the induced changes in the output of intermediates in an economy that is relatively unproductive in the research lab.

The stock market plays a crucial role in the growth of industry and trade, which eventually affects the economy. This paper studies the determinants of stock market development in Jordan using yearly time-series data (1978-2019). The autoregressive distributed lag approach is applied to examine co-integration, while the vector error correction model is employed to estimate (long-run and short-run) causal relationships. The results show that macroeconomic determinants such as gross domestic product, gross domestic savings, investment rate, credit to the private sector, broadest money supply, stock market liquidity, and inflation rate are important determinants of stock market development. These findings provide vital implications for policymakers in developed and emerging stock markets. First, economic development plays an imperative role in stock market development. Second, developing the banking sector is mandatory because it can significantly promote stock market development. Third, domestic investment is a significant determinant of stock market development, especially in emerging countries. However, it is vital to launch policies that lead to encourage investment and promote stock market development, and this could be done through (1) encouraging competition, (2) improving the institutional framework, and (3) removing trade blocks by establishing a mutual connection between foreign private investment entities and government authorities.

본 논문은 ICT산업에 속한 기업들의 부채수준이 투자수준에 미치는 영향을 분석한 것이다. ICT 산업의 경우 급격한 기술발전과 빠른 시장변화로 지속적인 투자가 필요한 산업이다. 특히 이머징마켓의 경우 대부분은 국가에서 ICT 산업에 대한 정책적 지원이 이루어지고 있다. 전통적으로 기업의 높은 부채비율은 투자를 감소시키는 것으로 평가되었다. 그러나 이 같은 관계는 성장기회를 고려하지 않은 결과이다. 따라서 본 연구는 이머징마켓의 ICT기업과 Non-ICT기업의 투자수준과 부채비율을 비교하고 나아가 해당 산업에서 부채비율이 투자수준에 미치는 영향을 분석하였다. 분석결과에 따르면 많은 선행연구와 달리 이머징마켓에 속한 ICT기업은 부채비율이 높더라도 투자가 감소하지 않는 것으로 나타났다. 이는 성장성이 높은 기업에서는 높은 부채비율이 투자의사결정에 부정적인 영향을 미치지 않는다는 것을 증거를 제시한다는 의의가 있다.

Purpose: Compared to the rapid growth rate of the domestic automotive LED industry so far, the predictive analysis method for demand forecasting or market outlook was insufficient. Accordingly, product characteristics are analyzed through the life trend of LEDs for automotive exterior lamps and the relative strengths of p and q using the Bass model. Also, future demands are predicted. Methods: We used sales data of a leading company in domestic market of automotive LEDs. Considering the autocorrelation error term of this data, parameters m, p, and q were estimated through the modified estimation method of OLS and the NLS(Nonlinear Least Squares) method, and the optimal method was selected by comparing prediction error performance such as RMSE. Future annual demands and cumulative demands were predicted through the growth curve obtained from Bass-NLS model. In addition, various nonlinear growth curve models were applied to the data to compare the Bass-NLS model with potential market demand, and an optimal model was derived. Results: From the analysis, the parameter estimation results by Bass-NLS obtained m=1338.13, p=0.0026, q=0.3003. If the current trend continues, domestic automotive LED market is predicted to reach its maximum peak in 2021 and the maximum demand is $102.23M. Potential market demand was $1338.13M. In the nonlinear growth curve model analysis, the Gompertz model was selected as the optimal model, and the potential market size was $2864.018M. Conclusion: It is expected that the Bass-NLS method will be applied to LED sales data for automotive to find out the characteristics of the relative strength of q/p of products and to be used to predict current demand and future cumulative demand.

글로벌 경제위기이후 중국은 세계경제의 두 축의 하나로 부상하였으며, 한국경제에 가장 큰 영향을 미치는 국가로 자리매김 하고 있다. 그럼에도 불구하고, 현재까지 한국에서는 중국의 금융시장 특히는 자본시장에 관한 연구가 매우 적은 실정이다. 본 연구는 중국 심천증권거래소에 출범한 창업판시장을 살펴보고, 중국 중소벤처기업의 상장전후 경영성과를 비교분석하였다. 기술혁신 벤처기업과 고성장형 중소기업들의 자금조달을 목적으로 하는 중국 창업판시장에서 기업의 상장요건은 상해와 심천 증권거래소의 주시장보다 완화되어 있으며, 상장절차도 간소화되어 있다. 따라서 중국의 많은 기업들이 상장하고자 하며, 상장 경쟁도 매우 치열하다. 그리고 창업판시장에 최초로 상장한 36개 기업의 상장 전후의 경영성과를 살펴본 결과, 자기자본 순이익률 부채비율 영업이익증가율 등 3개 지표는 모두 크게 하락하였으며, 거의 모든 기업에서 이런 현상이 나타났다. 즉, 중국 창업판시장에 상장한 중소벤처기업들의 수익성과 성장성은 상장후 급속하게 하락하였으며, 많은 자금조달로 인하여 안정성만이 개선되어 있었다. 나아가 이러한 현상은 중소벤처기업들이 상장을 위하여 상장전 경영성과를 과대 포장한데서 기인한 것으로 분석되었다. 따라서 중국 증권감독관리위원회는 향후 상장기업에 대한 회계심사기준과 심사제도를 강화하여야 할 것이며, 분식회계기업에 대해서는 엄중한 제재조치를 실시하여 건전한 자본시장 풍토를 정착시켜야 할 것이다.

The nutrients such as protein, calcium, iron and all three of them, either by natural or chemical substances were added to the recipes of yeast breads. Acceptability test was carried for the each formulated bread before selecting eight experimental diets. Sixty albino rats were separated into ten dietary groups including eight enriched breads and two control diets of plain breads from the market, which were used as the carbohydrate sources of the each basal diet. Experimental regime was seven weeks. The growth rate, hematology, total serum protein and organ weights we compared. Generally animals on the enriched bread showed the better growth rate than the rats fed control diet. Diet H enriched protein, iron and calcium by natural foods, brought up the highest weight gain among all of the rats. Hemoglobin concentrations of the rats on the diet H and G (enriched with three nutrients by chemicals) were 14.3 and 14.2 gram % comparing with other two control groups (12.9 and 13.1 gram%). Rats on diet K (fed nothing but diet H enriched bread) showed the significantly higher growth rate, total serum protein and hemoglobin level than these on the diet L (fed only plain bread from the market).
