Unformatted text preview: What about r ? 2) Assume that F ( U , V ) exhibits constant returns to scale for U , V 0. a) Show that F ( U , V ) = UF U ( U , V ) + VF V ( U , V ) for all U , V 0. (Hint: Write down an equation that describes what happens if we increase U and V by a factor > 0 and differentiate by .) b) Now suppose that Y = F ( K , L ). Define K Y Y K K = L Y Y L L = Show that K + L = 1. c) Show that for a CobbDouglas production function F ( U , V ) = U V 1that K = ....
