''Cointegration among regional corn cash prices''
( 2015, Vol. 35 No.4 )
This study investigates cointegration among daily corn cash prices from seven Midwestern states for January 2006 ∼ March 2011, using both time invariant and time varying models. Changing cointegration is captured by time varying models, especially for the second half of the sample. The result identifies time periods for which a time invariant or time varying model is appropriate for further policy analysis.
