... problems of constrain-ed maximization when it is either difficult or impossible to solve the constraints for indi-vidual variables. At first we treat the method as a cook-book recipe. After we ... even easier. Abovewe derived:=1+There is no on the right-hand side, so when we take the partial derivative with respectto, the right-hand side is just a constant. Accordingly, = 0, i.e., Crusoe’s ... Consumption=1,forsome between zero and one. This particular Cobb-Douglas functionexhibits constant returns to scale, since (1)+( ) = 1.
