Abstract This paper seeks to estimate the long run behavioral equilibrium exchange rate in Nigeria. The empirical analysis builds on quarterly data from 1986Q1 to 2006Q4 and derives a Behavioral Equilibrium Exchange Rate (BEER) and a Permanent Equilibrium Exchange Rate (PEER). The econometric...

This paper presents a new class of time-deformation (or stochastic volatility) models for stock returns sampled in transaction time and directed by a generalized duration process. Stochastic volatility in this model is driven by an observed duration process and a latent autoregressive process....

DAMGARCH extends the VARMA-GARCH model of Ling and McAleer (2003) by introducing multiple thresholds and time-dependent structure in the asymmetry of the conditional variances. DAMGARCH models the shocks affecting the conditional variances on the basis of an underlying multivariate distribution....

In this paper we analyze the behavior of relative food prices for a set of 24 European countries observed during the period 1996.1 - 2007.7. Using new methods for analyzing nonstationary panels, we are able to show that relative food prices have a common component which accounts for a large...
