For an initial supply curve S 0, consumer surplus is the triangle above the line formed by price P 0 to the demand line (bounded on the left by the price axis and on the top by the demand line). If supply expands from S 0 to S 1, the consumers' surplus expands to the triangle above P 1 and below the demand line (still bounded by the price axis ...
Excess demand can raise the prices of products traded, and excess supply can lower them; but if supply and demand are relatively balanced, the question arises of what regulates the settled exchange-ratios (or average price-levels) of products traded in that case, and this is what the law of value is intended to explain.
