Emerging market economies have recently accumulated large stocks of foreign reserves. In this paper we address the question of what are the main factors accounting for reserve holdings in nine developing countries located in Asia and Latin America. Monthly data from January 1985 to May 2006 are...

This paper assesses empirically whether speculation affects oil price dynamics. The growing presence of financial operators in the oil markets has led to the diffusion of trading techniques based on extrapolative expectations. Strategies of this kind foster feedback trading that may cause large...

This study introduces a non linear model for commodity futures prices which accounts for the pressures due to hedging and speculative activities. The interaction with the corresponding spot market is considered assuming that a long term equilibrium relationship holds between futures and spot...

The growing presence of financial operators in the oil market has brought about the diffusion of techniques - such as feedback trading - which lead to departures of prices from their fundamental values and increase their variability. Oil price changes are here associated with changes in stocks,...

This study introduces a non linear model for commodity futures prices which accounts for pressures due to hedging and speculative activities. The linkage with the corresponding spot market is considered assuming that a long term equilibrium relationship holds between futures and spot pricing....

Monthly data are used to investigate reserves management in eight Asian and Latin American countries. Idiosyncratic explanatory variables enter into co-integration relationships based on a stochastic buffer stock model, where a reserve variability measure is obtained via conditional variance...
