In the production function (table), since at L = 0, the total output is 0, we deduce that at L = 0, A. the marginal product must be 1. B. the marginal product is 0. C. the marginal product is -1. D. none of the above.In the classical model, and from the production function (table) of a certain economy, suppose at L = 10, Y = 10, and at L = 11, Y = 16, then, when real wage is 5, the demand for labor must be: A. 10 units of L. B. less than 10 units of L. C. greater than 10 units of L. D. none of the above.In the classical model, if the productivity, measured by the marginal product of labor, increases at every level of labor, then the (equilibrium) real wage must: A. increase. B. decrease. C. stay the same. D. none of the above
