This study investigates the long-memory properties of the prices of three Kenyan commodities (tea, coffee and horticultural products) by applying fractional integration methods to monthly data spanning the period from August 1998 to December 2024. The empirical results provide evidence of...

Given the context of the COVID-19 pandemic disrupting global logistics, coupled with the Russia-Ukraine war causing global energy price changes, examining both the linear and nonlinear associations between shipping cost and oil price is crucial in a global context. This study empirically...

This paper analyzes three forecasting methods for commodity spot prices and applies them to copper prices. The first method uses futures prices from either LME or COMEX. The second method uses analysts' consensus expectations, reported by Bloomberg. The third method jointly uses futures and...

This paper aims to investigate the sensitivity of the gas market: Russian Natural Gas and Liquefied Gas, to other commodity categories. It sheds light on the Russian-Ukrainian crisis by using an Autoregressive Distributed Lag model on daily prices of Russian Natural Gas, Liquefied Natural Gas,...

Commodity-exporting economies, such as South Africa, are susceptible to wide fluctuations in their business cycles, closely tied to commodity price fluctuations. In this research, we develop a prototype dynamic stochastic general equilibrium (DSGE) model with specific features for emerging small...

Commodity price shocks can be a key driver of business cycles in resource-rich small open economies. We assess their importance for the Norwegian economy by estimating a structural VAR model and measuring the contribution of oil price shocks to fluctuations in economic activity. Focusing on the...

This paper analyzes the effect of commodity price fluctuations on a commodity-exporting economy. Using Chilean and international copper market data, I find that positive copper price changes resulting from copper-specific demand shocks generate a broad GDP expansion, with no visible decline in...

Countries facing commodity (net) export price shocks tend to implement fiscal rules and to financially close their economies, demonstrating "macroeconomic prudence". These effects are (unsurprisingly) asymmetric between import and export price shocks. The impact of commodity (net) export prices...

I propose partial-equilibrium models that describe the dynamics of global wheat and corn markets. These models extend the classic competitive storage framework by incorporating nonstationary variables. They are calibrated using data from Ukraine and key importing and exporting countries. The...

This study investigates the disconnect between falling agricultural commodity prices and persistent food inflation by applying a Heterogeneous Vector Autoregression (VAR) model to a panel of 203 countries using data from 1961 to 2022. It analyzes the impact of global crops, fertilizer, and oil...

Economic resources are often seen as decisive for the outcomes of military conflicts. This paper asks whether “deeper pockets” help win wars. We construct a fine-grained dataset covering more than 700 interstate disputes and rely on exogenous resource price shocks to estimate the causal...

Key aggregate figures on Austria's agriculture and forestry sectors show little change for 2024 compared to the previous year, although there were significant fluctuations in individual commodity markets, such as sugar beet. In foreign trade in agricultural goods and foodstuffs, imports expanded...

This study investigates the main drivers of inflation measured by CPI inflation and GDP deflator across 20 advanced and emerging economies over the yearly span from 2014 to 2023. Using Principal Component Analysis and Panel Vector Autoregression, the research examines the roles of supply-side...

When wealth or income rises suddenly, the propensity for that "easy money" to be directed towards unproductive use, "easy spending", may rise. The cross-country relationship between conspicuous consumption and revenue windfalls is explored by estimating the response of demand for imports of...

We develop an indirect inference approach relying on a linear supply and demand model serving as an auxiliary model to provide the first full empirical test of the rational expectations commodity storage model. We build a rich storage model that incorporates a supply response and four structural...

An early analysis of the imperialist implications of the surge of global commodity prices was conducted in 2014 by Jonathan Nitzan and Shimshon Bichler. However, their analysis did not consider how the US monetary and fiscal expansionist policies have contributed to the rise of global commodity...

This paper investigates the effect of commodity price shocks in a commodity-exporting small open economy, and the role of fiscal policy in transmitting these shocks to the rest of the economy. Using South African data, we first estimate an empirical model using a Bayesian vector autoregression...

We examine the vulnerability of inflation in Small Island Developing States (SIDS) to global food and fuel inflation changes, drawing on a large panel of 168 countries, including 31 SIDS. Estimates using the local projections methodology of Jordà (2005) reveal that inflation in SIDS is nearly...

As the uncertainty of the global economy intensifies, domestic real economy risks and financial risks may interact and worsen under international risk shocks. Commodity prices are an important channel for transmitting international economic and financial risks. Taking January 2007 to July 2021...
