We saw above that these were functions of current signals σ, via ,(^)] This indirect utility function now has as arguments first-period variables only: consumption xi9 the quantity of money saved mi9 and current pricequantity signals σ,. t. x, = ω, + z,· ^ 0 m, = m, - pZi ^ 0 -sik ^ Zik ^ dik k ^ h We may note that through the expectations imbedded in the indirect utility function, expected constraints produce spillover effects just as well as current constraints.

And on a set of parameters 77,, which are themselves estimated on the basis of price-quantity signals, as we shall see later. We can thus denote the perceived demand curve as SihiPh Vi) and we shall assume that it is nonincreasing in ph. As explained in Chapter 1, the perceived demand curve is denoted as a constraint on the sales of agent 1, since the total demand of the other agents represents the maximum quantity that agent 1 can sell. Symmetrically, the perceived supply curve of an agent /, who determines the price of a good h that he buys, will be denoted as DihiPh Vi) and we shall assume that it is nondecreasing in ph.

A more complete exposition with further develop­ ments is found in Benassy (1982b). 9 CONCLUSIONS 57 The concept of fixprice equilibrium described in this chapter is taken from Benassy (1975a, 1977b), where a more "subjective" approach of perceived constraints was adopted. An alternative concept of fixprice equilibrium is found in Drèze (1975); see also Younès (1975), Böhm and Levine (1979), and Heller and Starr (1979). The introduction of expectations in non-Walrasian equilibrium models was made in Benassy (1973, 1975a).
