Assume that a Cobb-Douglas production function is a good representation of the economy, the substitution effect is stronger than the income effect, and that the economy was initially at equilibrium. Suppose that Congress passes a law that guarantees all adults an annual income of $80,000 whether they work or not. If the real wage was perfectly flexible and given the change in the labor market, what would happen to the production function where output is plotted against labor? A downward shift of the entire production function A rightward movement along the production function (therefore no shift of the production function) O A leftward movement along the production function (therefore no shift of the production function) An upward shift of the entire production function
