Consider a 2x2 production economy with two firms, X and Y, and two factors of production, labor L and capital K. The total endowment of factors in the economy is 100 units of labor and 100 units of capital, so (Ē, K) = (100, 100). Firm X can produce output good X using labor and capital. The firm's technology is described by the following continuous and differentiable production function: fx(lx, kx) = alx + (1 − a)kx,

Question
Consider a 2x2 production economy with two firms, X and
Y, and two factors of production, labor L and capital K. The
total endowment of factors in the economy is 100 units of labor
and 100 units of capital, so (L, K) = (100, 100).
Firm X can produce output good X using labor and capital.
The firm's technology is described by the following continuous
and differentiable production function:
fx(lx,kx) = alx + (1 – a)kx,
where lx 2 0 is the quantity of labor and kx > 0 is the
quantity of capital employed by firm X, and a e (0, 1) is a
production parameter.
Firm Y can produce output good Y using labor and capital.
The firm's technology is described by the following continuous
and differentiable production function:
fr (ly, ky) = lk8,
where ly > 0 is the quantity of labor and ky >0 is the quantity
of capital employed by firm Y, and ß E (0, 1) is a production
parameter.
This is a small open economy, so output prices for goods X
and Y, (px,pY) >> 0, are given. For all of the following
problems, the price of the output good Y is 1 (i.e., Py = 1).
