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.

The exchange rate is a very important macro variable that has influence on the whole economy and has, therefore, been the topic of many discussions amongst policymakers, academics and other economic agents. The issue of whether to have a fixed, pegged or floating exchange rate regime was highly debated during the 1970s. The purpose of this paper is to investigate what factors determine the exchange rate in Somalia. Quantitative research methodology has been employed to develop regression model using time series data for the period of 12 years. The regression model has been developed based on Quantity theory of money, purchasing power parity and uncovered interest rate parity theory. Somalia is on the countries where the highest exchange rate volatility exists; for example in 2012, the rate jumped 29% percent and two weak later dropped 21%, when Turkish humanitarian aid agencies injected the market a lot of U.S dollar. Based on my study using regression model for time series data of 12 years, the four factors are mainly attributable for the exchange rate volatility of Somalia; these factors include the balance of payment, inflation rate, money supply (mostly come from remittance and NGOs) and Bank profits.

The study explores the nexus between foreign direct investment (FDI), financial innovation, and exchange rate volatility in selected South Asian countries for 1980 to 2017. The study applies the unit root test, Autoregressive Distributed Lagged, nonlinear ARDL, and causality test following Toda-Yamamoto. Unit root tests ascertain that variables are integrated in a mixed order; few variables are stationary at a level and few after the first difference. Empirical model estimation with ARDL, Long-run cointegration revealed with the tests of FPSS, WPSS, and tBDM by rejecting the null hypothesis of "no cointegration." This finding suggests that, in the long-run financial innovation, FDI inflows, and exchange rate volatility move together. Moreover, study findings established adverse effects running from FDI inflows and financial innovation to exchange rate volatility in the long run. These findings suggest that continual FDI inflows and innovativeness in the financial system assist in lessening the volatility in the foreign exchange market. Furthermore, nonlinear ARDL confirms the presence of asymmetric cointegration in the model. The standard Wald test established asymmetric effects running from FDI inflows and financial innovation to exchange rate volatility, both in the long and short run. Directional causality unveils feedback hypothesis holds for explaining causality between FDI, financial innovation, and exchange rate volatility.

This paper reviews four different kinds of currency crisis models proposed to explain the Korean crisis of 1997 to examine which model is more relevant to explain the Korean crisis of 2008. According to the author's investigation, the 'Frenkel-Neftci' cycle is more relevant model to interpret the Korean crisis of 2008. In 2008, spreads opened due to, first, high interest rate policy by the Korean government aimed to suppress real estate price increase, and, second, the expectation about exchange rate appreciation, and thirdly stock market returns after recovering the crisis. Then the international capital market catastrophe due to the subprime crises produced the sudden change of expectation of the market participants. Huge capital outflows resulted from the credit crunch in the international capital markets, and the possibility of exchange rate depreciation by the Korean government to promote exports in the course of the global recession.

The exchange rate volatility has been increased since the time when the floating exchange rate system was introduced in Korea. As a result, the increase of the exchange rate volatility raised the risk in international trades in Korea. The purpose of this study in to study the feature of exchange rate volatility and the main sources of its increase and to confirm whether the exchange rate volatility influence export volume and price of Korea. In the first place, I measured exchange rate volatility with two methods. The one is descriptive statistic method such as the width of daily exchange rate fluctuation and the rate of exchange rate devaluation. The other is the time varying conditional variance of exchange rate. Then, I studied the sources of exchange rate volatility. In the second place, I defined the exchange rate volatility as the time varying conditional variance and estimated it by using elastic a approach model which shows exchange rate is affected by itself and its conditional variance, I estimated its effects on export volumes and prices of electric home appliances, information & communication equal and semi-conductor. The result of this study is as follows. With presumed result EU and Korea because is not the goods which is to substantial competition relationship, The effect where the relative value change of presumed result expression anger and the dollar of import and export function goes mad to the import and export of Korea the income compared to is to export and it is appearing a lot. The EU goods is sold more expensively the Korean goods than from about length being caused by American market of the dollar and the balance of trade of Korea is visible like being visible the improvement of single breadth. Because the relationship of competition is weak but substantially there is to a short term and expression - the effect where the dollar rate fluctuation is big in Korean trade there is a possibility of saying that widely known it is not.

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.

While the issue of RMB (Renminbi, Chinese Yuan) revaluation became the focus of world attention in 2003, the reform of the RMB exchange rate regime in 2005 didn't fundamentally solve the RMB appreciation problem, and even in 2008 the global financial crisis made RMB appreciation face new challenges and risks. It appears that the rise in RMB value is caused by supply exceeding demand in China's foreign exchange market; however, intrinsically it is due to the asymmetry in RMB exchange rate formation mechanism. The export tax rebates policy implemented by Chinese government is one of the leading causes of the asymmetry. This study constructs a transmission model between export tax rebates and foreign exchange rates, and applies the Granger Test to validate the causality between kernel variables based on correlative data from 1994-2011, and uses the error correction method to analyze the quantified relations of kernel variables, and finally gets the contribution rate of export tax rebates to RMB appreciation.

이 논문은 외환위기 이후 1998년 1월 ~ 2008년 7월 까지의 한 일 주가와 KRW/JPY 실질 환율간의 장 단기 균형관계를 분석하였다. 실증분석은 월별자료를 사용하여 계절조정에서 오는 편의(bias)를 극복하기 위하여 자료를 계절조정하지 않고 계절성을 모형에 반영하여 단위근 검정과 VEC모델을 분석하였다. 실증분석결과 한일 주가와 환율간 장기균형관계에 대한 강한 증거를 발견하였다. 이는 한 일 양국간 어느 한 국가에 대한 시장예측은 다른 국가 시장에 대한 예측이 가능하다는 것으로 효율시장가설이 위배됨을 의미한다. 한국의 주가와 KRW/JPY 실질 환율 간 장기 음(-)의 부호를 나타내 국내통화의 절하는 국내기업을 더 경쟁적으로 만들어 수출의 증가를 이끌기 때문에 주가를 상승시키며, 주가와 환율간 음(negative)의 상관관계를 의미한다는 전통적 가설을 지지하는 것으로 나타났다.

Applying Ismailov and Rossi (2018), I newly construct the Korea FX uncertainty based on the density distribution of historical forecast errors. This uncertainty index properly captures the rare but significant events in the Korean currency market and provides information distinct from other uncertainty measures in recent studies. I show that 1) FX uncertainty arising from unexpected depreciation has a stronger impact on Korea-U.S. exchange rates and that 2) macro variables, such as capital flows or interest rate differentials, have predictive ability regarding Korea FX uncertainty for short horizons. These findings enable us to predict the events of sudden currency crashes and understand the Korea-U.S. exchange rate dynamics.

본 연구는 생산비에 영향을 미치는 요인의 하나로서 환율이 변화할 때, 친환경 자동차의 품질 향상과 시장점유율 확대에 상충적 효과가 유발됨을 보인다. 우선 고품질의 친환경 자동차와 저품질의 내연기관 자동차로 구성된 수직적 차별화 복점 모형에서, 각 기업이 품질 수준과 가격을 순차적으로 결정하는 완전정보하의 두 단계 비협조게임을 설정한다. 그리고 각 종류의 자동차가 서로 다른 화폐를 사용하는 두 국가에서 구분되어 생산될 때, 내연기관 자동차를 생산하는 국가 화폐의 환율이 상승하여 그 자동차 생산비가 상대적으로 저렴해지면, 생산자는 경쟁 심화를 선호하게 되고, 품질 수준 차별화 축소의 시도로부터 품질 향상 유인이 발생한다. 이때 친환경 자동차 생산 기업은 경쟁력 약화로 인해 경쟁을 회피하려고, 품질 차별화 확대를 위한 품질 수준 제고의 동기를 갖는다. 그렇지만 이 경우 친환경 자동차의 시장점유율은 위축된다. 만일 환율이 반대 방향으로 변화하면, 친환경 자동차의 점유율 확대가 기대되지만, 두 자동차의 품질 수준은 모두 저하되는 상충적 효과가 유발된다.
