This paper examines the information shares in four pairs of Canadian a
gricultural cash and futures markets by exploring their cointegrating
relationships. Using error correction models (ECMs) and Hasbrouck's ec
onometric method of estimating information shares, the results show th
at the price discovery process is most pronounced in the futures marke
t. The identification and quantification of the dominant market of pri
ce discovery is of great interest to both hedgers and speculators. The
advantage of Hasbrouck's technique is that it facilitates the quantif
ication of the concept of price discovery and market dominance.
