چکیده
Aim: Commodity exporting nations have significant terms of trade swings, making their actual exchange rate unstable. This study looked at how variations in dollar affected food commodity prices Africa between 1990 and 2021.
 Design/Research methods: The conducted GARCH analysis for ascertaining prevalence volatilities rates interest respectively selected African countries. Also, we estimated both static dynamic driven by panel least squares generalized method moments (GMM) estimators on data from some commodity-exporting African, namely, Ghana, Gabon, Tunisia, Nigeria, South Africa.
 Findings: GMM results reveal taken together had positive effects prices. estimates demonstrate volatility growth using normal t multivariate distributions. However, based empirical findings, t-distribution largest maximized log-likelihood -8920.1 also a satisfactory df 26.82 (<30). that the Nigerian Naira highest coefficient approximately 71.2%. was followed Ghanaian Cedi with negative 71% rand 65%. while all countries respect to rate, except Ghana currency. Nigeria showed volatility. A possible explanation this high aforementioned is persistent domestic inflation.
 Originality: originality rooted establishment having relation pervasive shocks. an indication adverse downward adjustment local currencies vis-à-vis US covered study.
 Contributions: contribution lies its increase due variability calculated depreciation rate. Empirically, it confirmation structural problem, variation as cause inflation countries.
 Limitations: Results be interpreted care small sample size. are rather working hypothesis future research.

The paper summarizes key findings of alternative lines of research on the relationship between food and fuel markets, and identifies gaps between two bodies of literature: one that investigates the relationship between food and fuel prices, and another that investigates the impact of the introduction of biofuels on commodity-food prices. The former body of literature suggests that biofuel price...
متن کاملModeling variations in the cedi/dollar exchange rate in Ghana: an autoregressive conditional heteroscedastic (ARCH) models
This research article aimed at modeling the variations in the dollar/cedi exchange rate. It examines the applicability of a range of ARCH/GARCH specifications for modeling volatility of the series. The variants considered include the ARMA, GARCH, IGARCH, EGARCH and M-GARCH specifications. The results show that the series was non stationary which resulted from the presence of a unit root in it. ...
متن کاملCan Exchange Rates Forecast Commodity Prices?
This paper demonstrates that “commodity currency” exchange rates have remarkably robust power in predicting future global commodity prices, both in-sample and out-of-sample. A critical element of our in-sample approach is to allow for structural breaks, endemic to empirical exchange rate models, by implementing the approach of Rossi (2005b). Aside from its practical implications, our forecastin...
