We consider forecasting and prequential (predictive sequential) validation of meta-elliptical distributions with time varying parameters. Using the weak prequential principle of Dawid, we conduct model validation avoiding nuisance parameter problems. Results rely on the structure of...

Currently, evidence on the ‘resource curse’ yields a conundrum. While there is much crosssection evidence to support the curse hypothesis, time series analyses using vector autoregressive (VAR) models have found that commodity booms raise the growth of commodity exporters. This paper adopts...

This paper investigates the role of aid in mitigating the adverse effects of commodity export price shocks on growth in commodity-dependent countries. Using a large cross-country dataset, we find that negative shocks matter for short-term growth, while the ex ante risk of shocks does not seem to...

Commodity and energy prices have exhibited an unprecedented increase between October 2006 and July 2008, only to fall sharply during the last months of 2008. Many explanations have been offered to this phenomenon, including steadily increasing demand from China and India, large mandated...

Prices for nearly all basic commodity rose at unprecedented rates throughout early 2008, only to fall nearly as fast as financial markets and global economies began to collapse. Rising food prices in 2008 led to concerns that commodity price spikes would lead to more general food inflation, but...

Exchange rates have long been thought to have an important impact on the export and importof goods and services, and, thus, exchange rates are expected to influence the price of thoseproducts that are traded. At the same time, energy impacts commodity production in somevery important ways. The...

The relationship between complete-feed prices and ingredient prices is estimated in order to analyze the effect of higher commodity prices on feed costs, with particular attention paid to the substitutability of corn distillers dried grains with solubles (DDGS). Using the historical price...

Commodity producers in general typically have a commodity driven cost baseas well as commodity price driven revenue stream. The research reportinvestigates the correlation between input commodity price and gold price forgold mining companies, and how commodity price behaviour could...
