The rationing scheme is thus written as di∗ (t) = d˜i (t) × min 1, s˜ (t) , ˜ d 1 (t) + d˜2 (t) i = 1, 2 s ∗ (t) = min[˜s (t), d˜1 (t) + d˜2 (t)] (36) (37) Let us assume that each trader knows the rationing rule and the demands and supplies of the others after they have been expressed. Moreover he expects these to remain the same from period t − 1 to period t. The perceived rationing scheme is thus for demander 1, φ 1t (d˜1 ) = d˜1 × min 1, s˜ (t − 1) d˜1 + d˜2 (t − 1) (38) and similarly for demander 2.

In such a market each agent receives, in addition to the traditional price signal, some quantity signals. 2 These may be represented as z i∗h = min(˜z i h , d¯i h ), z˜ i h ≥ 0 min(˜z i h , −¯si h ), z˜ i h ≤ 0 (17) 2 We exclude manipulability because, as we noted in the appendix to chapter 1, manipulable schemes lead to a perverse phenomenon of “overbidding” which prevents the establishment of an equilibrium (see B´enassy 1977b, 1982).

If we finally consider an increase in government spending G, we see that it increases employment and production but actually crowds out private consumption. All in all, we see that this model yields an allocation that has “Keynesian” inefficiency properties but reacts to government policy in a somewhat similar way to that of a Walrasian model. All this will be studied in more depth in chapter 4, where we will consider a model of similar inspiration but with rational expectations and objective demand curves.
