This paper examines the persistence of shocks to world commodity prices, using monthly IMF data on primary commodities between 1957-98. We find that shocks to commodity prices are typically long-lasting and the variability of the persistence of price shocks is quite wide. The paper also...

The essential aim of this paper is to analyze wood consumption in Great Britain over the period 1850-1938. We calculate the apparent consumption of wood in Britain, taking into account both net imports of wood and the home harvest of wood. Then we develop some quantitative exercises which...

The debate of environmental issues and their analysis is of vital interest for economic policies. Institutions are engaged in identifying and estimating the extent of environmental impact of determinants controllable via policy measures. Annual data from the on Carbon Dioxide emission, economic...

The objective of this paper is to analyze the degree of persistence of final energy demand in Portugal. Our results suggest the presence of a strong level of persistence for aggregate final energy demand. Final demand for gas is the most persistent component of energy demand, while the final...

Due to its non-storable nature, electricity is a commodity with probably the most volatile spot prices, exemplified by occasional spikes. Appropriate pricing, portfolio, and risk management models have to incorporate these characteristics, and the spikes in particular. We investigate the nature...

A persistente escalada do preço dos combustíveis fósseis à qual está associada uma enorme volatilidade de curto prazo, assim como as crescentes preocupações com as emissões de gases com efeitos sobre as alterações climáticas, alimentou nos últimos anos a discussão e as...

This paper investigates the global macroeconomic consequences of falling oil prices due to the oil revolution in the United States, using a Global VAR model estimated for 38 countries/regions over the period 1979Q2 to 2011Q2. Set-identification of the U.S. oil supply shock is achieved through...

The impact of population growth on the environment is an issue that is highly debated yet comparatively under-researched empirically. This is true despite a vast number of published articles on the link between population and environmental changes speculating on the sign of the environment...

We propose a new time series model aimed at forecasting crude oil prices. The proposed specification is an unobserved components model with an asymmetric cyclical component. The asymmetric cycle is defined as a sine-cosine wave where the frequency of the cycle depends on past oil price...

The aim of this study is twofold – on the one hand, to report a flow analysis based on historical trends of steel, from 1997 to 2008, across some leading geo-economic players; on the other, the analysis of long-term relationship between steel consumption and economic growth by the sensitivity...
