Harmony implies a condition of no change. Clearly, at the balance cost, the two purchasers and merchants are in a condition of no change. In fact, at this value, the amount requested by the purchasers is equivalent to the amount provided by the dealers. Both market powers of interest and supply work in concordance at the balance cost. At the point when the cost of item expands, the dealers rush to the market with their items for a chance to win higher benefits. This makes a state of overabundance supply, at last prompting an excess of the specific item in its market.
