Aims: The aim of this   study is to examine   multivariate GARCH modeling of selected Nigerian economic data. Study Design: The study used monthly data of Nigerian crude oil prices (dollar Per Barrel), consumer price Index rural, maximum lending rate and prime lending rate. Methodology: This work covers time series data on crude oil prices, consumer price Index rural, maximum lending rate and prime lending rate extracted from   Central Bank of Nigeria (CBN) from 2000 to 2019. In attempt to achieve the aim of the study, quadrivariate VECH and DCC model were applied.  Results: The results confirmed that returns on economic data were correlated. Also, diagonal multivariate VECH model confirmed one of the properties that it must be ‘positive semi-definite’, And the DCC confirmed also the positive-definite conditional-variance. Conclusion: From the results obtained, it was confirmed that there exists a strong confirmation of a time-varying conditional covariance and interdependence among Nigeria economic data. As for cross-volatility effects, past innovations in crude oil price have utmost control on future volatility of returns on economic data. It was also confirmed that time varying covariance displays among these economic data and lower degree of persistence and based on Model selection criteria using the Akaike information criteria (AIC) has 17.485 for diagonal VECH  while for DCC has 17.509 AIC  which makes  VECH model  better fitted.

Aims: The aim of this study is to examine Economic data using the multivariate GARCH model. Study design: The study used monthly data of Nigerian crude oil prices (dollar Per Barrel) and Consumer price Index Methodology:  This work covers time series data on crude oil price and consumer price Index rural obtained from   Central bank of Nigeria (CBN)   from 2000 to 2019. To achieve the aim of the study, bivariate VECH and BEKK model were applied. Results: The results confirmed that returns on economic data were correlated. Also, diagonal multivariate VECH model confirmed one of the properties that it must be ‘positive semi-definite’ and the BEKK also confirmed the volatility spillover effects among the economic data. Conclusion: From the results obtained, it was confirmed that conditional variances depends only on own lags and own lagged square returns and conditional covariances depends only on own lags and own lagged cross products of returns. As for cross-volatility effects, past innovations in crude oil price have greatest influence on future volatility of returns on economic data. It was also confirmed that time varying covariance displays among these economic data and lower degree of persistence and based on Model selection criteria using the Akaike information criteria (AIC) diagonal VECH model is better fitted than the BEKK model.

Relationship Of

This research is an attempt to framework the applied strides to evaluate the long run relationship among commonly used inflation proxies induces such as, wholesale price index (WPI) and consumer price index (CPI), and crude oil price (COP) with KSE100 index returns. In this research we used monthly data for the time period from July 1995 to June 2016, and thus, in this way total 252 observations have been considered. Time series have been made stationary by applying ADF and PP tests at first difference. Johansen multivariate conintegration approach was used to test the long-term association amongst the considered macroeconomic variables. The results indicated that CPI and COP significantly affect KSE100 index returns that indicated CPI along with COP have foreseen power to impact KSE100 index. In contrary, the results of WPI and COP do not have long run relationship with KSE100 index in case of Pakistani economy. Results of variance decomposition exhibited that the index of LKSE100 was realistically rarer exogenous in connection to distinctive factors, as around 92.31% of its variation was explained due to its own specific shocks. It is concluded that CPI and COP can impact the KSE100 index returns. It is confirmed by the results of impulse response function that there is a positive and long run relationship between KSE100 returns and consumer price index (proxy of inflation) and international crude oil prices.

Gold Reserve

Gold is a valuable asset to a country because of its liquidity. Gold reserve can stabilize the currency in a country. The objective of this paper is to identify the factors contributing to the volatility of gold prices, such as Real Malaysia GDP, inflation rates, crude oil prices and exchange rates. The data was analysed using Autoregressive Distributed Lag (ARDL) approach with time series data, with 30-year coverage from 1987 to 2016. Findings showed that only Real Malaysia GDP and crude oil prices were significantly related to gold prices. As a conclusion, this study can be used as reference by other investors. The author suggests to other researchers to further improve upon this study by adding more variables or diversifying the variables that relate to volatility of gold prices.

Corn Prices

Corn belongs to the most important feed and industrial grains in the world being utilized for bioethanol production. Ukraine does not produce biofuels and does not pursue an active renewable energy policy. However, due to significant share of exports, corn prices in Ukraine can be shaped under the influence of biofuel policies pursued by developed countries, as well as under the influence of world energy markets. Therefore, the aim of the paper is to investigate the mechanisms linking Ukrainian export corn prices with Brent oil prices, as well as to quantitatively assess the nature of this relationship. We were especially interested in possible time-varying relationship between the prices. The price analysis was carried out on the basis of monthly data for the period 2001-2020 with the use of rolling correlation technique and rolling causality tests. The results of this research indicate on time-varying co-movements of Ukrainian corn and Brent crude oil prices. The strongest positive correlations and significant bidirectional causality were observed in 2007-2011. However, in most of sub-periods there were no significant relationships between these prices. Among factors strengthening the price linkages are the low corn-oil price ratios, dynamic increase of corn utilized for ethanol production and depletion of the world corn stocks. The conducted analysis confirmed that changes in biofuel demand in other countries can affect Ukrainian corn market due to horizontal integration of grain markets worldwide. Biofuel policy reforms in the EU aiming at decreasing mandatory blending of conventional biofuels in favor of advanced biofuels can lead to decrease in demand for corn in Ukraine after 2021, leading, in turn, to further weakening of linkage between corn and crude oil prices.

The Impact

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.
