Trade hurts O A. mobile factors. O B. all factors in the economy. O C. the factor that is specific to the import - competing sectors. O D. the factor that is specific to the export sector of each country.Suppose a specific factors economy produces two goods: X and Y. Given that the economy is open to trade, and assuming that D is consumption, Q is production, and P is price, the budget constraint can be defined as O A. PY Dx - Qy = PX x (Qx - DY) O B. PXDx + PxQx = PyDy + PyQy O C. PX Dx - Qx = Py x ( Q - DY ) OD. PY Dx - Qx = P X x ( Qy - DY )
