본 논문은 한미 및 한일경제 간에 커버되지 않은 이자율평가에 대한 실증연구를 수행한다. 환율결정에 대한 화폐 및 자산균형모델의 예측이 이 경우에 성립되는지를 중점적으로 분석한다. 화폐 및 자산균형모델과 같은 대부분의 환율결정이론은 환율의 예측에 있어서 정확하지 못한 것이 사실이다. 그러나 이러한 사실에도 불구하고 실질환율과 실질이자율차이 사이에는 강력한 관계가 존재한다고 논의되어 왔다. 그러므로 한미, 한일경제에 있어서 이들 두 변수 간에 강력한 상응관계가 존재하는지의 여부를 조사하는 것은 중요하다. 한미, 한일경제 간의 실질환율과 실질이자율차이 사이의 관계는 공적분 테스트를 통해 분석될 수 있다. 실증결과는 화폐적 변동, 즉 이자율의 차이가 조사기간 동안 환율의 변동을 잘 설명하지 못하고 있음을 나타낸다. 또한, 이들 두 변수 간에 공적분이 성립되지 않음은 두 변수의 비정상성을 야기하는 충격이 동일하지 않다는 것을 나타낸다.

This study focus on interest for arrears and filling of the gaps left in Article 78 of CISG. In the case of CISG, Article 78 provides for interest any time a payment under a contract is untimely, but does not specify a particular rate of interest or a method to determine such a rate. This issue did not cause any uncertainty under ULIS, the CISG's antecedent, since Article 83 of ULIS provided for 1%p above the official discount rate in the creditor's country. Lacking any CISG general principle as well as any indication by the very same CISG, one can only conclude that the matter must be deferred to the domestic rule of private international law. Actually, resorting to private international law is not only admissible, but expressly required by Article 7(2). In the interpretation and filling of the gaps left in Article 78, there is a considerable difference of opinion especially amongst commentators on whether the gap is a lacuna praeter legem, i.e., one being governed by, but not expressly settled in the CISG, or whether it is an issue falling outside the scope of application of the CISG, i.e. a lacuna intra legem. The protagonists of the former view lay emphasis on the overall objective of the CISG, namely to create a uniform law, whereas the supporters of the latter view refer to the legislative history of Article 78 as the dominant principle in interpreting Article 78. Some authors believe that the issue of determining the rate of interest is not dealt with by CISG and it is, therefore, governed by the applicable domestic law, which is the subsidiary law applicable to the sales contract, since "no special connecting points seem to have developed for the entitlement to interest." In the light of the relevant case law, it seems correct to conclude that the interest rate is not determined by CISG and that courts normally determine it according to their own rules of private international law. While CISG Article 78 expressly does not deal with this issue, PICC Article 7.4.9 and PECL Article 9.508, on the other hand, set forth a precise method for computing interest. Although a method like the one set by PICC may be useful and may encourage uniformity, it still cannot be used under the CISG. The PICC or PECL formula may, however, be a very good starting point in a de jure condendum analysis when a new Article 78 will be drafted, if an interest rate method will ever be embodied in the text of an international convention.

Derivative-linked securities (DLS) is a type of derivatives that offer an agreed return when the underlying asset price moves within a specified range by the maturity date. The underlying assets of DLS are diverse such as interest rates, exchange rates, crude oil, or gold. A German 10-year bond rate-linked DLS and a USD-GBP CMS rate-linked DLS have recently become a social issue in Korea due to a huge loss to investors. In this regard, this paper accounts for the payoff structure of these products and evaluates their prices and fair coupon rates as well as risk measures such as Value-at-Risk (VaR) and Tail-Value-at-Risk (TVaR). We would like to examine how risky these products were and whether or not their coupon rates were appropriate. We use Hull-White Model as the stochastic model for the underlying assets and Monte Carlo (MC) methods to obtain numerical results. The no-arbitrage prices of the German 10-year bond rate-linked DLS and the USD-GBP CMS rate-linked DLS at the center of the social issue turned out to be 0.9662% and 0.9355% of the original investment, respectively. Considering that Korea government bond rate for 2018 is about 2%, these values are quite low. The fair coupon rates that make the prices of DLS equal to the original investment are computed as 4.76% for the German 10-year bond rate-linked DLS and 7% for the USD-GBP CMS rate-linked DLS. Their actual coupon rates were 1.4% and 3.5%. The 95% VaR and TVaR of the loss for German 10-year bond rate-linked DLS are 37.30% and 64.45%, and those of the loss for USD-GBP CMS rate-linked DLS are 73.98% and 87.43% of the initial investment. Summing up the numerical results obtained, we could see that the DLS products of our interest were indeed quite unfavorable to individual investors.

The purposes of this article is to analyse how market competition of credit card company affect price(interest rate) and survival length of card users. This paper uses individual account data from a large Korean credit card company during the periods from 2002 to 2006. The findings of our study are as follows. First, market competition of credit card company have a negative effect with interest rate of credit card. Second, market competition of credit card company have a affirmative effect with survival length. Finally, The effect of Increasing delinquency rate due to price increase is smaller than decreasing delinquency rate due to extending survival length.

본 연구는 예상환율변화율, 예상인플레이션 차이, 및 이자율 차이를 활용하여 한국의 외환시장, 실물시장, 및 화폐시장 간의 상호관계를 분석하였으며, 계량경제기법으로는 합리적 기대가설과 GARCH-M 모형을 적용하였다. 또한, 국제 Fisher 효과를 분석하여 국내외의 실질이자율이 국가간 자본유출입에 미치는 영향도 분석하였다. 분석결과에 의하면 한국의 경우 외환시장의 효율성을 실물시장 및 화폐시장간의 유기적인 관계로 이해하기에는 한계가 있지만 외환시장에서 결정되는 환율은 국가간 실질이자율의 충격에 영향을 받는 것으로 판명되었다. 따라서 외환시장의 안정성을 확보하기 위해서는 국가간 실질이자율의 차이를 안정적으로 유지하는 정책을 수행하여야 할 것이다.

최근의 글로벌경제위기 상황에서 국내 금융외환시장이 높은 환율변동을 보이며 불안한 모습을 보이고 있다. 따라서 그 어느 때보다 금리, 환율 등 가격변수들의 움직임 및 이들 간의 관계에 대한 관심이 높다. 본 연구에서는 국내시장을 중심으로 환율, 금리의 추이 및 인과관계에 대하여 연구하였다. 글로벌경제위기 상황에서 원/달러환율, 콜금리의 움직임에서 나타나는 주요 특징을 알아보고, 교차상관분석 및 그랜저 인과관계검정 등을 이용하여 두 변수간의 상호연관관계에 대하여 선도/지연 관계를 중심으로 분석하였다.

This scholarly work is an effort to capture the effects of oil prices on the actual exchange rate between dollar and rupee. This is done with reference to the U.S. dollar as oil prices are marked in USD (U.S. Dollar) in the international market, and India is among the top five importers of oil. Using monthly data from January 2001 to May 2020. The study used the real GDP, money supply, short-term interest rate difference between two countries, and inflation apart from the crude oil prices per barrel as the factors that help define the exchange rate. The analysis, through cointegration and vector error correction method (VECM), suggests long and short-run causality amid prices of oil and the rate of exchange fluctuations. Oil prices are found to be negatively related to the exchange rate in the long term but positively related in the short term. The result of the Wald test also indicates the short-run causation from the short-term interest rate and the prices of crude oil towards the exchange rate. The present study shows that oil prices are evidence of the existence of short-term and long-term driving associations with short-term interest rates and exchange rates.

This paper examines the time series dynamics of spot and forward exchange rates and Eurocurrency deposit rates for four bilateral relationships vis a vis the U.S. dollar using daily data. The equilibrium implied by covered interest parity provides a theoretical foundation from which to estimate and analyze the dynamic properties of each system of exchange rates and interest rates. The structural statistical model is identified by relying on the implied cointegration vectors and long-run neutrality restrictions.

본 연구에서는 융합 시대를 맞이하여 국내 수출에 영향을 미치는 지표들을 찾고자 금리와 원/달러, 원/엔, 원/위안화를 선정하였다. 지난 2000년 1월 이후 210개월 동안 상관관계와 회귀분석, 지표분석, 모형분석 등을 시도하였다. 분석결과 상관분석에서는 수출이 원/달러, 원/위안화, 원/엔 환율과 음(-)의 관계를 보여 서로 방향성이 다르게 나타났다. 회귀분석에서는 수출에 대해 금리와 원/달러만 통계적으로 유의하게 나타났다. Coefficient가 금리는 양(+)의 값으로, 원/달러는 음(-)의 값으로 산출되었다. 원/달러 하락이 수출 증가에 긍정적으로 작용하는 것으로 추정되었다. 본 연구에서 원/달러 환율이 하락하면 수출이 증가하는 것으로 나타나 기존 선행연구와 다르게 나타났다. 그래서 시간차에 의한 선후행 관계를 다시 살펴볼 필요성이 제기되었다. 우리나라는 수출에 대한 의존도가 높은 편이다. 따라서 수출 증가를 위해 수출에 영향을 미치는 지표들에 관한 연구가 지속되어야 할 것이다.
