Resumen
Descripción
We apply nonparametric methods to assess price transmission processes within the EU pig markets. We compare results derived from nonparametric regressions with those obtained using alternative nonlinear threshold models. Results show that nonparametric regressions support the parametric results. However, parametric techniques often suggest a higher degree of price transmission than that implied by threshold models.
