Price asymmetry between different pork cuts in the USA: a copula approach

Panagiotou, Dimitrios and Stavrakoudis, Athanassios (2015): Price asymmetry between different pork cuts in the USA: a copula approach. Published in: Agricultural and Food Economics , Vol. 3, No. 6 (29 January 2015)

Abstract

The objective of this study is to assess the degree and the structure of price dependence between different cuts in the US pork industry at the retail level. To this end, it utilizes monthly retail data of pork cuts and the statistical tool of copulas. The empirical results suggest that for all pairs, retail prices are not likely neither to boom nor to crash together, even though overall dependence is quite considerable for two of the three pairs considered in this study. No evidence of asymmetric price co-movements was found.
