In fact, w ith international market prices about one-third higher than probably expected in 2008, tariffs could even be cut by rates larger than w'hat appeared potentially acceptable in 2008. As suggested above, one reason behind the step increase in world market prices for agricultural commodities that appears to have occurred since 2006 was a cost push caused by rising energy prices. One can probably argue that this cost push has also raised the target level of domestic prices by the same order of magnitude. On a global scale, tariffs applied for agricultural products have come down to about one-half of the tariffs bound (Bureau and Jean, 2013b).
