Unformatted text preview: (b) convex  averages produce more than extremes 6. Marginal product (a) MP 1 is how much extra output you get from increasing the input of good 1, holding good 2 Fxed (b) MP 1 = ∂f ( x 1 ,x 2 ) /∂x 1 7. Technical rate of substitution 1 (a) like the marginal rate of substitution (b) given by the ratio of marginal products (c) TRS = dx 2 dx 1 =∂f/x 1 ∂f/x 2 8. Diminishing marginal product (a) more and more of a single input produces more output, but at a decreasing rate (see Fgure 18.5. in the textbook) (b) law of diminishing returns 9. Diminishing technical rate of substitution (a) equivalent to convexity (b) note di±erence between diminishing MP and diminishing TRS 10. Long run and short run (a) all factors varied long run (b) some factors Fxed short run 11. Returns to scale (a) constant returns  baseline case (b) increasing returns (c) decreasing returns 2...
