Inverse demand systems explain price variations as functions of quantity variations. They have properties analogous to those of regular demand systems. There are very few examples of their empirical application. In part this is due to lack of data for which price is the decision variable and the quantity given. The case of fish landed at Belgian sea ports appears to suit an inverse demand system well. A Rotterdam variant of such a system in estimated. Allais interaction intensities have been derived and show a reasonable pattern.
