Suppose that a production function, f , is homogenous of degree , i.e., f ( L,K ) = f ( L,K ). (a) Under what conditions does such a production function have constant returns to scale? (b) Prove that MP L is homogenous of degree -1. (c) Prove that L df dL + K df dK = f ( L,K ). 5. For what values of a and b will the production function f ( L,K ) = ( L a + K a ) 1 b for a , b > exhibit increasing, constant, or decreasing returns to scale? 1...
