본 논문은 외환보유고 축적이 신흥경제권의 금융시스템에 중 장기적으로 어떠한 영향이 미치는지에 대해서 고찰하였다. 외환보유고의 축적은 신흥경제권에 있어서 금융위기의 재발방지라는 관점에서 매우 유효한 수단이며 금융위기의 리스크를 줄이기 위한 수단이기도 하다. 외환보유고의 과도한 축적이 경제적으로 대외채무, 국내소비, 국내투자 및 경제성장에 각각 어떠한 영향을 미치는지 중 장기적인 관점에서 보면 외환보유고의 축적이 국내소비를 감소시키는 한편 수출증가에 의한 무역재 산업의 확대를 가져온다. 즉 무역재 산업의 확대는 무역재 산업이 자본집약적인 경우에 국내투자의 확대를 통해서 경제성장에 긍정적인 영향을 준다. 그러나 중국은 국내투자를 대폭적으로 확대하는 정책을 실시하고 있지만 그 외의 국가에서는 과도한 외환보유고의 축적으로 인해서 국내투자가 정체되고 있다. 이러한 사실은 중국을 제외하고 과도한 외환보유고의 축적이 비무역재 산업의 축소를 통해 중 장기적으로 경제성장을 침체시킴으로서 잠재적인 리스크가 높아진다는 것을 의미한다.

최근 국제자원시장의 불안정성으로 인해 카스피해 연안 국가에 대한 관심이 고조되고 있다. 이들 국가들은 자원수출 중심으로 성장하고 있으며, 특히 카자흐스탄은 최근 10년간 높은 경제성장률을 달성하였다. 그러나 자원에 대한 수출의존도가 높은 경제구조를 가진 국가들의 경우 경제 전반이 국제자원 시세변동에 따라 크게 영향을 받을 수 있으며, 지속적인 경제성장을 저해하는 네덜란드 병에 노출될 수 있다. 최근 카자흐스탄은 우리나라와 교역 및 투자가 증가하는 등 새로운 에너지 공급처로서 대두되었다. 따라서 카자흐스탄의 경제변화는 우리나라에 있어 주요 이슈라고 할 수 있다. 이 연구에서는 카자흐스탄 경제에 네덜란드 병의 원인을 파악하기 위해 Balasa-Samuelson모형을 수정하여 1999년 1월부터 2008년 12월까지를 표본 대상 기간 동안 국제유가와 이자율, 카자흐스탄 실질환율 간의 관계를 분석하였다. 실증분석 결과 전체 표본 기간 내 국제유가와 이자율은 실질환율과 장기적 균형관계를 보이는 것으로 나타났다. 이 기간 내 국제유가와 이자율은 실질환율에 각각 부(-)의 영향을 미치는 것으로 나타나 카자흐스탄은 네덜란드 병에 노출되어 있음을 확인하였다.

This paper discusses the design of monetary policy in a New Keynesian small open economy framework by introducing nominal wage rigidities and incomplete exchange rate pass-through on import prices. Three main findings are summarized. First, with the existence of an incomplete exchange rate pass-through and nominal wage rigidities, the optimal policy is to seek to minimize the output gap, the variance of domestic price and wage inflation, as well as deviations from the law of one price. Second, the CPI inflation targeting Taylor rule is welfare enhancing when there is a technological shock to the economy. The exception occurs when there is a foreign income shock, which minimizes welfare losses under the domestic inflation targeting Taylor rule. Last, two stylized Taylor rules turn out to be a bad approximation, but the modified Taylor rules that respond to the unemployment gap rather than the output gap are a closer approximation to the optimal policy.

China's increasing trade volume and continuous integration with global financial markets have strengthened the influences of the renminbi on the exchange rates of different currencies. Previous studies find closer co-movements between the renminbi and other currencies. This paper is novel to investigate the underlying determinants of the co-movement further, using panel data of over thirty-four countries. Our results show that stronger bilateral trade and financial linkages with China have a positive association with the currency co-movement. Moreover, countries with greater flexibility in exchange rate regimes show stronger co-movements. These findings imply that growing co-movements are the consequence of autonomous decisions at the market rather than that of management by governments or central banks.

Recently, many companies have launched a new business model related to the mobile gift service in order to achieve or sustain a competitive advantage in the fast-growing mobile market. Due to the well combination of mobile technology advantages and offline gift-giving motivations, a mobile gift service has been proliferating over recent years. Although the motivation of mobile gift purchasing behavior can be different from that of offline gift purchasing behavior, there is still a lack of research on what factors are influencing and how they are impacting mobile gift purchasing behavior under diverse gift-giving settings. Therefore, based on both exchange and motivation theories as well as literature review, this study identified three influencing factors-economic (immediate rewards, convenience), social (friendship needs, reputation), and personal (enjoyment, self-satisfaction) benefits-and validated their impacts on intention to repurchase a mobile gift. Moreover, the moderating roles of intimacy and gift price in the relationships between benefits and mobile gift repurchasing intention were examined. The results provide many implications for marketing managers on how to enhance consumers' intention to repurchase, which in turn leads to sales and increased profit.

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.

Rural areas have been faced with various problems such as aging and population decline, and in these circumstances, the activation of local communities is suggested as a solution. Agricultural producer organizations are a powerful means of maintaining rural society. The purpose of this study is to understand the characteristics of agricultural community activities by region by comparing the status of organization and activities and analyzing Location Quotient(LQ) based on the regional survey data in the 2015 census of agriculture, forestry, and fisheries. As the results of the analysis, it was found that 38.35% of villages participated in economic organizations and 32.22% of villages were having urban-rural exchange activities. The crop clubs were actively operated in the Gyeongsangbuk province, and other economic organizations were organized in Jeju, Haenam-gun, and Dangjin-si more than other regions. And the urban-rural exchange activities were found in Chungcheongnam province mainly. The results of detailed LQ analysis by organization and activity showed that specialized regions for each community or activity were different. These results could be used for regional planning or the establishment of strategies for community activation.

2020년 코로나19 발발 이후 한국 경제를 포함한 국제 시장 환경은 급속하게 변하고 있고 한국 금융시장의 중요 경제 지표인 원/달러 환율도 요동치고 있다. 대외 의존도가 높은 한국 경제에서 환율에 대한 이해는 항상 중요한 연구 과제였고, 특히 코로나 확산이 환율에 미치는 연구는 시기적으로 많은 경제 학자들의 관심사이기도 하다. 따라서 본 연구는 코로나19 발발 이후 환율과 경제 지표의 관계를 분석하고 환율 예측을 위한 단변량 다변량 예측 모형을 구축하여 모형의 예측 성능을 비교 검증을 하였다. 코로나 전후 기간을 세 기간으로 나눠서 기간 1은 코로나 발발전과 초기, 기간 2는 코로나 대확산, 기간 3을 코로나 안정기로 나누고 기간 1의 환율 데이터를 학습한 SARIMA 모형과 같은 기간의 경제 변수와 환율 데이터를 학습한 ARDL 모형의 예측 성능을 비교하였다. 기간별 RMSE기준으로 SARIMA 모형은 기간 2에서 예측 성능이 뛰어나고 ARDL 모형은 기간 3에서 예측 성능이 가장 우수한 것으로 나타났다. 연구 결론은 환율과 경제 변수의 통상적인 관계가 나타나는 기간 3에서는 변수 관계를 반영하는 ARDL 모형이 좀 더 예측 성능이 좋은 모델이고 기존의 전형적인 환율과 경제 변수의 패턴에서 벗어난 과도기 시기인 기간 2에는 과거 환율 추이만 반영하는 SARIMA 모형이 좀 더 우수한 예측 성능을 보여주는 모델로 검증되었다.

It is widely recognized that economic time series involved not only the linearities but also the non-linearities. In this paper, when the economic time series data have the nonlinear characteristics we propose the forecasts method using combinations of both forecasts from linear and nonlinear models. In empirical study, we compare the forecasting performance of 4 exchange rates models(AR, GARCH, AR+GARCH, Bilinear model) and combination of these forecasts for dairly Won/Dollar exchange rates returns. The combination method is selected by the estimated individual forecast errors using Monte Carlo simulations. And this study shows that the combined forecasts using unrestricted least squares method is performed substantially better than any other combined forecasts or individual forecasts.

The agricultural sector has an important contribution to the economic development of Vietnam in particular and other countries in general. The growth of enterprises in the industry is an important bridge in promoting the economic development of the country. Currently, the policies of the Government of Vietnam always create favorable conditions for enterprises to conduct business, especially enterprises in the agricultural sector. The study aims to assess factors influencing the profitability of listed firms in Vietnam's stock market. Using 40 enterprises in the agricultural industry listed on the Ho Chi Minh City Stock Exchange and the Hanoi Stock Exchange and using advanced econometric modeling, dealing with defects in the regression model, the research results show that large-scale firm has higher economic efficiency than small-scale firm. In addition, a firm with higher use of loan capital is associated with a more efficient firm, reflected in the relatively good debt management ability of enterprises in the agricultural sector. Adversely, growth and age do not have any impact on firm performance. Macroeconomic factors do not impact profitability. Finally, the study has some policy implications for developing agricultural businesses in the case of Vietnam.
