This study uses the panel probit model to investigate and evaluate the relationship between exchange rate regimes, political stability, and carbon dioxide during currency crises. To understand currency crisis times, we study a panel dataset of seven South Asian nations that contain annual observations from 1996 to 2020. Furthermore, we created the EMPI exchange market pressure indicator to detect crises. Our results strongly suggested that fixed exchange rate is negatively associated with currency crises, with good regulatory quality and better effective governments. Simultaneously, the floating exchange rate is positively related to the currency crises in those countries where the rule of law has less adequately flowed. However, CO₂, exports, and interest rates are buoyantly associated with crises. The floating exchange rate, the rule of law, exports, and interest rate are associated positively and contribute more prone to the crisis episodes. Negatively associated variables contributed less amid crises episodes: fixed exchange rate regime, government effectiveness, and regulatory quality. Meanwhile, CO₂ has a positive relationship with a currency crisis and contributes more likelihood to the probability of a currency crisis. Countries that adopted the fixed exchange rates with effective governments and regulatory quality faced more minor currency crises.

In this paper, we address how the monetary authority should react to financial market status and exchange rate movements in a small open economy New Keynesian model with financial frictions due to asymmetric information between savers and borrowers. We show that the small economy with financial frictions is more susceptible to the exogenous shocks under the fixed exchange rate regime than under the flexible exchange regime. The small economy experiences a more prolonged and deeper economic recession under the fixed exchange rate regime than under the flexible exchange rate regime. The monetary policy taking into account external finance premium is better than the interest rate rule without considering the financial market status.

We conducted modeling experiments to evaluate the residence times and exchange rates of seawater in Gamak Bay, located on the southern coast of the Korean Peninsula. The results revealed that pollutants are more quickly dispersed in a fixed grid rather than in a variable grid system. Pollutant concentrations decayed exponentially with time after release near the mouth of the bay, whereas no exponential variations were seen at the northwest end of the bay. The mean exchange rate of the seawater was 1.58% per day in the variable grid system, and the residence time of pollutants was greater than 288 days in Gamak Bay. Conversely, the exchange rate of seawater in Gamak Bay, as revealed by the particle tracking method, was 65% over a 50-day simulation. The results suggest that the seawater exchange in Gamak Bay is so low that pollutants are likely to remain in the bay indefinitely.

Purpose - The purpose of this paper was to analyze the Chinese government's announcement of the RMB's appreciation on July 1, 2010, and its aim was to ascertain whether the appreciation has affected Chinese export prices by empirically measuring the degree of the exchange rate pass-tough on those prices. Research design, data, and methodology - Using 73 HS trade categories with cross-industry and time-series data, the panel estimation of a fixed-effects model has been applied to measure the degree and stability of any exchange rate pass-through effects. The estimation results show that the export prices of most trade categories were affected by the exchange rate changes. The pass-through effect was generally small, at about -0.485, and statistically significant in most export prices. Results - The empirical results indicate that China would lose its advantage and competitiveness in export if the RMB were appreciated continuously and rapidly because its export goods would no longer operate under strong monopolistic competition. Conclusions - The implications for China's exchange rate policy suggest that it would be better for the RMB to appreciate slowly and gradually rather than radically. It is clear that it would be allow the capital free flow in Chinese overall economic interest to reduce the continuous appreciation pressure on the currency and pave the way for improvements in export distribution competitiveness.

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.

Using panel data for 29 developed countries, this paper studies the relationship between financial flow and trade markets on Dutch diseases for the period 2000-2010 and applying a fixed effects model. In particular, the study shows that an increase in inflows of foreign direct investment (FDI) leads to an appreciation of the real exchange rate. The result also suggests that an inflow of FDI accompanied by exports or government expenditure from tax revenue leads to real exchange rate appreciation. This paper also argued that stock market with FDI does not cause an appreciation of the real exchange rate.

본 논문은 한국의 근본적인 거시경제변수가 두 가지 다른 환율제도(자유변동 환율제도와 시장평균 환율제도)하에서 어떻게 다르게 반응하는가를 분석 연구한다. 이와 아울러 같은 기간 동안의 일본과 호주의 거시경제구조에 대한 비교 분석도 곁들인다. 한국은 1997년의 경제위기를 전후하여 환율정책을 시장평균 환율제도에서 자유변동 환율제도로 전환하였다. 이 시점을 계기로 한 한국의 외환정책 변경은 두 가지 환율제도를 비교 분석하는 데 아주 좋은 기회를 제공한다. 화폐경제이론에 기초한 환율결정 모델을 사용하여 대미환율과 거시경제변수에 대한 관계를 분석해 본 결과, 대미환율은 시장평균 환율제도하에서보다 자유변동 환율제도하에서 근본적인 거시경제변수에 더 민감하게 반응하는 것으로 나타났다. Impulse Response Analysis 분석결과에 의하면, 환율변동이 물가상승률에 미치는 영향은 시장평균 환율제도하에서 보다 자유변동 환율제도하에서 단기적으로 더 큰 것으로 나타났다. 이러한 결론은 개발도상국가에서는 안정적인 관리 환율제도가 경제성장을 위해 필요하다는 일반적인 견해와 일치하는 것이다.

본 논문에서는 이기종 컴퓨팅을 활용한 환율 예측 뉴럴 네트워크를 구현했다. 환율 예측에는 많은 양의 데이터가 필요하다. 그에 따라 이러한 데이터를 활용할 수 있는 뉴럴 네트워크를 사용했다. 뉴럴 네트워크는 크게 학습과 검증의 두 과정을 거친다. 학습은 CPU를 활용했다. 검증에는 Verilog HDL로 작성된 RTL을 FPGA에서 동작 시켰다. 해당 뉴럴 네트워크의 구조는 입력 뉴런 네 개, 히든 뉴런 네 개, 출력 뉴런 한 개를 가진다. 입력 뉴런에는 미국 1달러, 일본 100엔, EU 1유로, 영국 1파운드의 원화 가치를 사용했다. 입력 뉴런들을 통해 캐나다 1달러의 원화가치를 예측 했다. 환율을 예측 하는 순서는 입력, 정규화, 고정 소수점 변환, 뉴럴 네트워크 순방향, 부동 소수점 변환, 역정규화, 출력 과정을 거친다. 2016년 11월의 환율을 예측한 결과 0.9원에서 9.13원 사이의 오차 금액이 발생했다. 환율 이외의 다른 데이터를 추가해 뉴런의 개수를 늘린다면 더 정확한 환율 예측이 가능할 것으로 예상된다.

This paper examines how macroeconomic variables, such as interest rate differences, inflation, exchange rates, economic growth and external debt growth, affect capital flight in the ASEAN-8 countries. We apply a panel data model with fixed effect estimation for the data for eight countries from the period 1994 to 2018. We use the residual approach used by the World Bank to measure the value of capital flight. The results show that the interest rate differences, exchange rates, economic growth and foreign debt growth had a positive and significant effect on outward capital flight. A further implication of this finding is that the interest rate differences, exchange rate, economic growth and foreign debt growth are factors that trigger an increase in capital outflow in the ASEAN-8 countries. Nonetheless, inflation rate is not considered to be the main factor influencing capital flight, as average inflation in the ASEAN-8 countries remains relatively stable. This paper will be beneficial for policymakers in the ASEAN-8 countries and encourage them to constantly pay attention to these four variables, as they significantly influence capital flight, whereas they can disregard the impact of the inflation variable that is not significant in influencing capital flight.

The oil and gas industry is widely known as a vital engine of Vietnam development, stimulating researchers to examine the association of various factors with this industry. The aim of this study is to identify the relationship between different variables affecting profitability of the firms in the oil and gas sector in Vietnam. The total of 203 samples were collected from 29 companies listed on Vietnam Stock Market during a 6-year period from 2012 to 2018. Informed by prior research, this investigation employs financial leverage (FL), government ownership (GOV), dividend payout (DIV), fixed assets to total assets (FA) and exchange rate (EXR) as independent variables, while the profit is described by return-on-assets (ROA). The study results show that there are four factors that have an impact on ROA, namely, leverage, government ownership, dividend, and exchange rate. Whereas leverage and exchange rate have negative influence on ROA, government ownership and dividend payment have a positive effect. The findings of this study suggest that high debt ratio in capital structure and the negative effect of exchange rate on their companies' efficiency can adversely affect the profit of enterprises. Also, plausible extent of government ownership and dividend payment could also be considered to optimize corporate performance.
