<p>最近在看微观经济，关于机会成本总是搞不清。想请教大家一下</p><p>1.机会成本和经济成本的关系</p><p>例如看曼昆的书里提到Revenue - Opportunity costs = Economic Profit，我的理解就是Opportunity cost = Ecnomic Cost</p><p>可是看另外一本书就说Economic costs are defined by economists as total costs, which are the sum of outlay costs, and opportunity costs, 这里所说的outlay cost 又是什么呢？</p><p>2.机会成本和隐性成本的关系</p><p>还是曼昆的书提到 显性成本 + 隐性成本 = 机会成本。 可是有的书提到，机会成本就是隐性成本。我都糊涂了，谁能告诉我哪个说法是对的。</p><p>xiexie</p>
