Abstract

En este trabajo se contrasta la eficiencia del mercado español del aceite de oliva puro a través del cumplimiento de la Ley de Precio Unico (LPU), considerando las zonas de consumo que, para este producto, define el MAPA. El análisis se lleva a cabo desde la perspectiva de la teoría de la cointegración, contrastando la LPU a largo plazo mediante el procedimiento propuesto por Johansen. Los resultados indican la existencia de tres relaciones de cointegración entre las series de precios analizadas, aunque no evidencian el cumplimento de la LPU. Los constrastes de exogeneidad débil revelan que Andalucía y Noreste pueden ser considerados como mercados líderes.
