a competitive firm uses two inputs and has a production function
f(X1,X2)=13X1X2( x1與x2的指數皆為1/4)
the firm can buy as much of either factor as it likes at factor prices
w1=w2=1, the cost of producing y units of output for this firm is?
a) 2(y/13)^2
b)13(X1+X2)/y
c)(X1+X2)/13
d)y/26
答案算的出來 是a
不過這題除了MRTS的觀念解還有別的角度下去解嗎? 謝謝^^
