Relación de causalidad entre el índice de precios del productor y el índice de precios del consumidor incorporando cambios estructurales. El caso de México

This paper analyzes the causal relationship between producer and consumer prices in the case of Mexico during the period 1994:01-2012:02. To do this, we use three unit root tests (Dickey-Fuller, 1979 y 1981; Phillips-Perron, 1988; Lee-Strazicich, 2003) and two tests of causality (Granger,1969; Toda y Yamamoto,1995). The results indicate that taking into account structural changes and the deterministic trend, both price indexes are stationary. We find unidirectional causal relationship running from CPI to IPP.
