We propose an alternative algorithm referred to RVM (relevance vector machine) to circumvent the support vector machine’s (SVM) unnecessary use of basic functions, a large number of support vectors, lack of probabilistic prediction, and longer time computation complexity (TCC). Global annual land-ocean average temperature (GASAT) data and WTI oil market price data extracted from the National Aeronautic and Space Administration US and the US Energy Administration, respectively. The data were preprocessed and used to build RVM models. To evaluate the proposed RVM, its performance was compared to that of a SVM. The results were validated using ANOVA. A significant correlation between the two datasets was found. The relevance vectors for the RVM were significantly less than the support vectors for the SVM, and the TCC for the RVM was significantly better than the TCC for the SVM. The prediction accuracy of both the RVM and the SVM were found to be statistically equal. The RVM model was able to project the impact of GASAT on WTI crude oil prices from 2014 to 2023. The projection can be used by intergovernmental organizations to formulate a global response to combat WTI crude oil price negative impact, which is expected to worsen in the next decade.

Purpose of the study: In this paper, we investigate the impact of the changes in crude oil prices and fluctuation of foreign exchange rate on the operating performances of Taiwanese 3PL industry.Methodology: Vector Autoregression Models. Through the empirical model, we find that all the 3PL companies are more suffered to the volatility of WTI and Dubai crude oil prices, but Dubai is insignificant to the warehousing companies. In the fluctuations of foreign exchange rate, some have positive effect and some are negative.Main Findings: All the Taiwanese 3PL companies are more suffered to the volatility of WTI and Dubai crude oil prices, however Dubai is insignificant to the warehousing companies. Moreover, we find an interesting result, that is, for some companies operating performance, the impact on the volatilities of crude oil have the same sign but in opposite direction. For example, in our empirical results, the stock returns are positively correlated to volatilities of Dubai and Brent crude oil prices, however, WTI’s volatility has negative impact on them.Implications: It implies that the company can make a “natural hedge” strategy to hedge the crude oil volatility risk by forming a portfolio which pools these three commodities together. In this way, we made recommendations to the company’s decision-making reminding that the company should make a portfolio of foreign exchange and crude oil price fluctuations in the hedge strategy to enhance the company’s risk management operations and to reduce the loss caused by these factors.Novelty/Originality of this study: This study contributes in the existing literature for an empirically study of a firm-level evidence from Taiwanese 3PL companies.

ABSTRACTAfter a brief description of the initial development of Venezuela's crude oil industry, this paper examines the impact the 1932 US tariff on crude oil imports had on the country. The US tariff on crude oil imports stabilised domestic crude oil prices but prevented consumers from benefting from lower prices in refned petroleum products. The large us international integrated crude oil companies gained from higher crude oil prices for their domestic production while supplying their european markets with mostly cheap crude oil from their newly developed Venezuelan oilfelds. The tariff increased the Venezuelan oil industry's vulnerability to international events because it narrowed the competitive edge it had over domestic us crude oil production. consequently, the Gómez dictatorship in Venezuela at the time became more dependent on the oil companies operating in the country since they could reduce production considerably, or even leave the country as quickly as they entered with a negative impact on government revenues.

This paper aims to examine the main determinants of inflation in Vietnam during the period from 2002Q1 to 2013Q2. The cointegration theory and the Vector Error Correction Model (VECM) approach are used to examine the impact of domestic credit, interest rate, budget deficit, and crude oil prices on inflation in both long and short terms. The results show that while there are long-term relations among inflation and the others, such factors as oil prices, domestic credit, and interest rate, in the short run, have no impact on fluctuations of inflation. Particularly, the budget deficit itself actually has a short-run impact, but its level is fundamentally weak. The cause of the current inflation is mainly due to public's expectations of the inflation in the last period. Although the error correction, from the long-run relationship, has affected inflation in the short run, the coefficient is small and insignificant. In other words, it means that the speed of the adjustment is very low or near zero. This also implies that once the relationship among inflation, domestic credit, interest rate, budget deficit, and crude oil prices deviate from the long-term trend, it will take the economy a lot of time to return to the equilibrium state.

This study investigates the dynamic relationship between crude oil prices and stock market price volatility in Nigeria using cointegrated Vector Generalized Autoregressive conditional Heteroskedasticity (VAR-GARCH) model. The study utilizes monthly data on the study variables from January 2006 to April 2017 and employs Dickey-Fuller Generalized least squares unit root test, simple linear regression model, unrestricted vector autoregressive model, Granger causality test and standard GARCH model as methods of analysis. Results shows that the study variables are integrated of order one, no long-run stable relationship was found to exist between crude oil prices and stock market prices in Nigeria. Both crude oil prices and stock market prices were found to have positive and significant impact on each other indicating that an increase in crude oil prices will increase stock market prices and vice versa. Both crude oil prices and stock market prices were found to have predictive information on one another in the long-run. A one-way causality ran from crude oil prices to stock market prices suggesting that crude oil prices determine stock prices and are a driven force in Nigerian stock market. Results of GARCH (1,1) models show high persistence of shocks in the conditional variance of both returns. The conditional volatility of stock market price log return was found to be stable and predictable while that of crude oil price log return was found to be unstable and unpredictable, although a dependable and dynamic relationship between crude oil prices and stock market prices was found to exist. The study provides some policy recommendations.


Significance The recent appointments of Secretary of State Mike Pompeo and National Security Advisor John Bolton, both critics of the deal, could contribute to Trump’s willingness to withdraw -- despite progress in consultations between Washington and its European allies to address US concerns. Impacts The reluctance of financial institutions to enter Iran’s market makes it difficult for firms to secure financing for their Iran operations. US secondary sanctions would have a particularly negative impact on Iran’s top European trading partners: Italy, France, Germany and Spain. A snapback of US sanctions would cut Iranian oil exports and push up crude oil prices.

United States President Donald Trump has just issued a controversial policy by giving Jerusalem recognition as the capital of Israel. This controversial policy triggered a strong reaction from a number of countries, especially Islamic countries including Indonesia. Indonesia through President Jokowidodo strongly condemned the policy of moving the Israeli capital to Jerusalem because it would disrupt political and security stability in the Middle East region. In the midst of the political impact caused by President Donald Trump's policies also affected the global economy. The world stock exchanges reacted immediately with the existence of these policies, one of which was the fall of the stock market index in Japan and South Korea due to investor concerns. The impact of the policies implemented by President Donald Trump also affected the Indonesian economy. This policy will affect the financial markets and capital markets in Indonesia. Trump's policy triggered an increase in the US $ exchange rate against the currencies of other countries including the Indonesian currency. Some of the negative effects on the Indonesian economy were the increase in world crude oil prices. Indonesia is currently no longer an oil exporting country, so that with the increase in world crude oil prices it will provide a fiscal burden in the State Budget (APBN). Fuel subsidies in the state budget will increase along with the increase in world crude oil prices that occur. In addition to the impact on the rupiah exchange rate against the US $, Donald Trump's policy also affects the inflation rate and the SBI interest rate. Through 2018, Bank Indonesia has raised the SBI interest rate by 150 basis points (bps) or 1.5%. The BI Governor explained that one reason for changing the benchmark interest rate was US monetary policy. The determination of high SBI interest rates also had an effect on reducing inflationary pressures. This study aims to look at the influence of President Donald Trump's policies regarding the transfer of the Israeli capital to Jerusalem against Indonesia's macroeconomic indicators. Indonesia's macroeconomic indicators are seen from 3 variables, such as the inflation rate, SBI interest rates and the rupiah exchange rate against US $ Key words :  Donald Trump, inflation, SBI interest rates, exchange rates / exchange rates

Abstrak Penelitian untuk menganalisis hubungan antara harga minyak dunia dan harga komoditi pangan di pasar domestik masih jarang ditemukan. Dengan membuat Model Panel Data dari 34 provinsi di Indonesia pada tahun 2010-2017, penelitian ini bertujuan untuk menginvestigasi pengaruh perubahan harga minyak dunia terhadap beberapa harga komoditi pangan lokal (kedelai,import, kedelai lokal, beras lokal, dan jagung lokal). Hasil penelitian ini mengindikasikan bahwa harga minyak dunia dapat memengaruhi harga pangan lokal di Indonesia melalui tingginya biaya pengiriman pada aktivitas impor. Selain itu, harga komoditi pangan dunia juga terbukti dapat memengaruhi harga seluruh komoditi pangan lokal yang diteliti, yang mengimplikasikan bahwa harga komoditi pangan di Indonesia dipengaruhi oleh kondisi pasar internasional. Hasil penelitian ini memberikan masukan bagi pembuat kebijakan di Indonesia untuk mempertimbangkan perubahan harga minyak dunia dan harga komoditi global dalam menstabilkan harga komoditi lokal di Indonesia, terutama komoditi yang diimpor.   Abstract Globally, studies examining the nexus between global crude oil prices and food commodity prices in domestic markets are scant. Employing a panel data model of 34 provinces in Indonesia from 2010 - 2017, this study investigates the impact of global crude oil’s price change on some local food commodity prices (imported soybean, local soybean, local rice, and local maize). Previous studies found that local food commodity prices in some countries were not affected by global crude oil prices; however, this study, by controlling other factors which could affect local commodity prices, finds different results. This study’s findings indicate that global crude oil prices could affect Indonesia’s local commodity prices due to higher shipping costs in import activity. In addition, global commodity prices are also proved to affect all commodities examined in this study, which implies that local food commodity prices in Indonesia are influenced by the international market. This study provides input to policymakers in Indonesia to consider the movement of global crude oil prices and global commodity prices in stabilizing local food commodity prices in Indonesia, especially the imported commodities.

The analysis of this research focuses on the interactive relationship among the fluctuation of crude oil prices, the real GDP and the stock market of United State. This empirical investigation uses data is in between 1990 and 2018 with the Vector Auto-regression (VAR) analysis, and multiple regressions with its assumption were used in order to analyses data.  Findings, oil price and economic growth are very important determinates of stock market in US because the p-value of this were less than the common alpha α =0.05. For instance, the crude oil price had positive impact on stock market because for each unit increasing of crude oil price, the stock market will increase by (0.276901) after holding all other variable constant. However, we find that GDP has negative impact on the participations of increasing the stock market.

Informed inflation expectations facilitate the extemporisation of a proper monetary policy framework that allows for the achievement of economic objectives, among them price stability. This study used the vector autoregression model to assess the impact of crude oil prices and exchange rates on inflation expectations in South Africa. Monthly time-series data for the period July 2002 to March 2013, obtained from the electronic database of the South African Reserve Bank were used. The study obtained statistically significant results suggesting that both crude oil prices and the exchange rates have a positive impact on inflation expectations in South Africa.
