A firm’s production function is ? = ?Lα ?β where A, α, and β are positive constants. The firm currently uses 500 units of labor and 40 units of capital. If the firm adds 1 more unit of labor, what happens to productivity of capital? Explain. Given a production function Q = f(L, K), if marginal product of labor and marginal product of capital are both positive, then this function displays diminishing MRTS. Explain if this statement is true or...

The specific rotations of the α and β anomers of D-glucose are +112 degrees and +18.7 degrees, respectively. Specific rotation, [α]D, is defined as the observed rotation of light of wavelength 589 nm (the D line of a sodium lamp) passing through 10 cm of a 1 g/mL solution of a sample. When a crystalline sample of α-D-glucose is dissolved in water, the specific rotation decreases from 112 degrees to an equilibrium value of 52.7 degrees. On the basis of...

Suppose all the students in a class are asked to choose between α and β simultaneously. If a student chooses “β” he/she immediately gets B +. If the student chooses “α”, then his/her payoff depends on the choices made by the other students. If at least 90% students choose α, then all of those who chose α get A, otherwise they get F.
