This allows us to write (z,z) = G(z), where G is a continuous mapping from Rnm into R^xR™. From the maximum theorem, strict quasi-concavity of Vt implies that functions ^ ( ) are continuous. We will write z = ^(z,z), where \ is a continuous mapping from K +m x K™ into Kwm. [G(z)] and We have ^(z^z^eK^ for all /z and all i. Consequently, the restriction of the function F to the convex compact set K is a continuous function from that set into itself. According to Brouwer's theorem, F ( ) has a fixed point z(*).

If the remaining goods supply ys — g is larger than the household's notional demand x*d, we have ls = fs0 and / > 0 subject to: y=f(i) Let (y*sXd) be the solution to this programme.

Ym(0)}. We have y(O) = O,f (0) = 0 and there is no bilateral, mutually beneficial trade if y>y(6). So far, we have restricted ourselves to fix-price equilibria viewed as departures from the Walrasian equilibrium. 3 extend to situations where real rigidities prevail on some markets, while other markets are perfectly competitive. By way of example, let us consider a productive economy including H workers, N identical firms, labour being the input, and a unique consumption good sold at price p.
