Compare this to a barter economy, where if I have goat and want an ox, I have to find someone willing to trade. Finding someone takes time and time is costly. With money, I can sell the goat and buy the ox. Thus, transaction costs are reduced. Having money as a medium of exchange would not reduce the inflation rate, interest rates, or the need to specialize in the production of those goods in which we have a comparative advantage (low opportunity cost producer). 求中文讲解，视频没声音
