AB  - This paper analyses the potato market spatial integration for Valle del Cauca. We use
weekly potato prices for the period 2003:52 – 2005:42. Traditional cointegration analysis has been
applied as well as an innovative approach: dynamic co-movement. This new approach implies
measures of time series cohesion (suggested by Croux, Forni and Reichlin (2001)). Results indicate
spatial market integration for Valle del Cauca. The time series traditional methods also show that
changes in Cali’s market prices precede changes in market prices of Armenia, Bogotá, Manizales
and Pasto. This result supports the evidence that Cali acts as a central market. Furthermore, dynamic
correlations are stronger in the long run than in relatively short periods of less than two and a half
weeks.
