能不能先给文中的"exchange economy "or" pure exchange ecnomy" 来个解释?
在MWG's "microeconomic Theory" 中, "A pure exchange economy (or, simply, and exchange economy) is and economy in which there are no production opportunities" (See page, 515),
可是在Lucas 的文章中,"The single good in this economy is (costlessly) produced in a number of these units"(page 1429, line4, 1st paragraph), that is to say, there are production opportunities in the economy.
