Greek Beef Supply Response and Price Volatility under CAP Reforms AgEcon
Rezitis, Anthony N.; Stavropoulos, Konstantinos S..
This study examines the supply response of the Greek beef market and the possible effect of the European Union’s Common Agricultural Policy (CAP) on the Greek beef sector during the period 1993-2005. A GARCH process is used to estimate expected price and price volatility while several different symmetric, asymmetric and nonlinear GARCH models are estimated. The empirical results show that price volatility and feed price are important risk factors of the supply repose function, while the negative asymmetric price volatility which was detected implies that producers have a weak market position. Furthermore, the empirical findings confirm that the annual premium paid by EU to beef producers had a positive impact on the production level and that the change of...

Greek meat supply response and price volatility in a rational expectations framework: A multivariate GARCH approach AgEcon
Rezitis, Anthony N.; Stavropoulos, Konstantinos S..
This paper examines supply response models in a rational expectations framework for each one of the four major Greek meat markets, i.e. beef, broiler, lamb and pork. A multivariate GARCH model with Cholesky decomposition is used to incorporate price volatility into the rational expectations supply response model for each meat category and as a result the conditional covariance matrix remains positive definite without imposing any restrictions on the parameters. The empirical results confirm the existence of rational behaviour by meat producers in the four examined markets and indicate that price volatility is a major risk factor in Greek meat production while feed prices and veterinarian medicine prices are both important cost factors. Furthermore, the...

Modeling Pork Supply Response and Price Volatility: The Case of Greece AgEcon
Rezitis, Anthony N.; Stavropoulos, Konstantinos S..
This paper examines the supply response of the Greek pork market. A GARCH process is used to estimate expected price and price volatility, while price and supply equations are estimated jointly. In addition to the standard GARCH model, several different symmetric, asymmetric, and nonlinear GARCH models are estimated. The empirical results indicate that among the estimated GARCH models, the quadratic NAGARCH model seems to better describe producers’ price volatility, which was found to be an important risk factor of the supply response function of the Greek pork market. Furthermore, the empirical findings show that feed price is an important cost factor of the supply response function and that high uncertainty restricts the expansion of the Greek pork...
