Consider a competitive market in which people consume at the point where their marginal rates of substitution between products X and Y are 3/5
In this same market, producers produce where their marginal rates of transformation between X and Y are also 3/5. However, producers are producing 7 of Y and 3 of X, and consumers wish to consume 5 of Y and 5 of X per unit of time. Explain how this situation can exist. Also determine if it represents an equilibrium or not. If not an equilibrium, what will tend to happen in the market?
