Assume that there are 100 markets in an economy. Prices have adjusted so that 98
markets are in equilibrium. Then Walras’ Law implies that
a) also the remaining two markets are in equilibrium
b) it is impossible that both remaining markets display excess demand
c) the market prices in the remaining two markets have to fall
d) the market prices in the remaining two markets have to rise
(b) i guess because if we ignore those 98 markets and just look at these two remaining markets, both cannot have excess demand although 1st market can have excess demand so that the 2nd market balance it.ie, if positive excess demand exists in one market, negative excess demand must exist in some other market.
therefore ans. will be-b) it is impossible that both remaining markets display excess demand
