Unformatted text preview: MRTS = L K We need to substitute for K (because it is a function of L along an isoquant). From the definition of an isoquant: q = L 2 + K 2 ( ) 1/2 q 2 = L 2 + K 2 K = q 2 ! L 2 ( ) 1/2 Substituting: MRTS = L q 2 ! L 2 ( ) 1/2 ! MRTS ! L = q 2 q 2 " L 2 ( ) 3/2 > This function does not have a diminishing MRTS. The isoquants are concave: e. Does the production function satisfy increasing returns to scale, constant returns to scale, or decreasing returns to scale? The function is constant returns to scale....
