Consider an economy that produces two goods, x and y. The production possibilities frontier for this economy is curved, and at the current production point, the marginal rate of transformation (MRTxy) in this economy is equal to 3. The economy also has an economy-wide indifference curve that is bowed in towards the origin. The marginal rate of substitution (MRSxy) is equal to 1 at the current production point. What must occur for this economy to reach a Pareto optimal outcome?
