One of the first lessons I learnt in Econ101 was that barter trade is inefficient compared with a money economy. Yet, in an interesting article in the FT's House & Home section (“Fair Trade”, May 16 2009) I read about the rising popularity of websites through which people can swap houses, instead of buying and selling them. Is this another example of how useful my economics degree is?
Confused Economist
我在初級(jí)經(jīng)濟(jì)學(xué)的頭幾堂課中就學(xué)到：易貨交易比貨幣經(jīng)濟(jì)效率低。但我在英國(guó)《金融時(shí)報(bào)》住房與家居版(House & Home)看到了一篇有趣的文章（2009年5月16日發(fā)表的《公平交易》(Fair Trade)）。該文寫(xiě)到，有一類(lèi)網(wǎng)站正愈發(fā)受到大眾的歡迎：人們可通過(guò)這種網(wǎng)站來(lái)交換房子，而非買(mǎi)賣(mài)。這是否再次說(shuō)明，我的經(jīng)濟(jì)學(xué)學(xué)位沒(méi)多大用？
