With ten equations at hand, one is redundant according to Walras's law
, leaving nine independent equations to solve for nine variables--two for the quantity of labor in each industry, two for the quantity of capital used in each industry, one for the total amount of watches and wheat, the real wage rate, the real return on capital, and the relative price of the two goods (Burmeister and Dorbell, 1970.
The new release of the book has already stimulated commentaries and discussions on this claim, as reflected in Van Den Hauwe's (2008) criticism of both this interpretation of Walras's Law
and its application in support of free banking as a stabilizing institution.
What economists three generations later were to call Walras's Law

Note that Walras's Law
requires that the profits of the firms go to the individual.
n); Walras's law
holds, that is, (p,E(p)) = 0 identically in P; weak gross substitutability prevails, that is, [E.
can be deduced from the application of Walras's law
in the national and international economy.
Their analysis winds up with monetary expansion producing an excess demand for goods unmatched by an excess supply of anything else, thus violating Walras's Law.
Through the use of Walras's Law, the IS-LM framework can correctly focus on just the two markets.
However, there is no clear presumption that this line slopes either upward or downward, although by Walras's Law it slopes less steeply upward than the LM curve or less steeply downward than the IS curve.
It is well-known that the equation called Walras's Law
operates in a mature Walrasian system and specifies that the sum in numeraire of the excess demands for all final commodities, including numeraire A itself, vanishes identically [Morrison, 1996, pp.
It is demonstrated that Walras's law makes the general equilibrium analysis of monopoly very tractable, although it was long thought that monopoly and general equilibrium were incompatible.
With fixprice theory, expressed demands and Walras's law part company.
