This paper investigates the presence of the bubbles that are experienced in the global vanilla (VNL) price, using the GSADF approach. The results show that there are five bubbles in the VNL price that are driven by specific reasons. Also, in this regard, the opening and ending points of each...

Recent energy and food price surges, in the wake of Russia's invasion of Ukraine, have exacerbated inflation pressuresthat are unusually high by the standards of the past two decades. High and rising inflation has prompted many emerging market and developing economy (EMDE) central banks and some...

This research sheds light on the causal link between commodity price indexes, i.e., the Agricultural Raw Materials Price Index, Industry Input Price Index, Metal Price Index, and Energy Price Index, in the global market, using wavelet coherence, Toda-Yamamoto causality, and gradual shift...

We propose a State-Space Model (SSM) for commodity prices that combines the competitive storage model with a stochastic trend. This approach fits into the economic rationality of storage decisions and adds to previous deterministic trend specifications of the storage model. For a Bayesian...

This paper uses annual data to study the interaction of consumer and commodity prices in 15 economies over the period 1850-1913. We find that consumer price inflation in all 15 countries co-moves with a broad measure of changes in commodity prices. Consumer prices comove most strongly with...

We develop an econometric modelling framework to forecast commodity prices taking into account potentially different dynamics and linkages existing at different states of the world and using different performance measures to validate the predictions. We assess the extent to which the quality of...

This paper is focused on the concise review of the specific applications of genetic algorithms in forecasting commodity prices. Genetic algorithms seem relevant in this field for many reasons. For instance, they lack the necessity to assume a certain statistical distribution, and they are...

I study the firm-level dynamic response of a commodity-exporting economy to global cycles in commodity prices. To do so, I develop a heterogeneous-firms model that endogenizes declines in aggregate productivity through reallocation towards less productive firms. Within a given sector, commodity...

With the rapid expansion of the RMB exchange rate's floating range, the effects of the RMB exchange rate and global commodity price changes on China's stock prices are likely to increase. This study uses both auto regressive distributed lag (ARDL) and nonlinear ARDL (NARDL) approaches to explore...

We study the effect of the upsurge of natural resources income from the commodity price boom of the 2000s on the functional distribution of income. To do so, we build a general equilibrium model of Dutch disease that characterizes how natural resource windfalls affect equilibrium factor shares....

In this article, we propose a cointegration-based Permanent-Transitory decomposition for nonstationary Dynamic Factor Models. Our methodology exploits the cointegration relations among the observable variables and assumes they are driven by a common and an idiosyncratic component. The common...

The present paper has two main objectives: first, to accurately estimate commodity price uncertainty; and second to analyze the uncertainty connectedness among commodity markets and the macroeconomic uncertainty, using the time-varying vector-autoregressive (TVP-VAR) model. We use eight main...

Commodity booms are usually associated with commodity-exporting countries suffering from real exchange rate appreciation and negative economic consequences, that is, Dutch disease. Yet, there are different ways to manage or not manage the commodity rent earned via exports. Based on a monetary...

The aim of this study is to test the ability of the yield curve on US government bonds to forecast the future evolution in the prices of commodities often used in as raw materials. We consider the monthly prices of nine commodities for more than 30 years. Our findings, confirmed by several...

The Prebisch-Singer (PS) hypothesis, which postulates the presence of a downward secular trend in the price of primary commodities relative to manufacturers, remains at the core of a continuing debate among international trade economists. The reason is that the results of testing the PS...

How important are liability dollarization in the transmission of commodity shocks on business cycles? To address this question, we developed a small open economy DSGE model with a banking sector and financial friction. The banks collect funds in the international capital markets in the form of...

We apply variance analysis for studying the risk-sharing mechanism in distribution channels, in which the risk-averse buyer and supplier are suffered from commodity price shocks. We obtain the closed-form optimal pass-through rate that minimizes the total channel risk and maximizes the channel...

This paper investigates the time-varying volatility patterns of some major commodities as well as the potential factors that drive their long-term volatility component. For this purpose, we make use of a recently proposed GARCH-MIDAS approach which typically allows us to examine the role of...

A multi-factor commodity portfolio combining the momentum, basis, basis-momentum, hedging pressure and value commodity factor portfolios outperforms significantly, economically and statistically, widely used commodity benchmarks. We find evidence that a variance timing strategy applied to...

Natural resources are often related to conflicts. The Dal B'o & Dal B'o (2011) theory states that income shocks affect capital- and labor-intensive sectors differently. Using sub-national cells covering the African continent for 1997-2010, I find that conflicts react differently to positive...
