Market Integration and Causality among Major Potato Markets in Haryana

Abstract

The market integration and causality of potatoes in Haryana were studied during the pre-e-NAM period (2010-2016) and the post-e-NAM period (2017-2021). Results of the study revealed that in both periods, prices of potatoes in the Gurugram and Rohtak markets showed an increasing trend, whereas, in the post-e-NAM period, the arrival of potatoes showed a decreasing trend in both markets. Rohtak and Gurugram markets were found spatially integrated with pre- and post-e-NAM periods. The Granger causality test in the pre-e-NAM period demonstrated that potato prices in the Gurugram market had unidirectional causation with the Rohtak market. In the post-e-NAM period, potato prices in the Rohtak market had unidirectional causation with the Gurugram market.
