Retrospectives: Ceteris Paribus
回顾了“其他条件不变”这一术语在经济学中的使用历史，指出其含义模糊，常导致分析意义存疑，适合对经济学方法论和语言哲学感兴趣的读者。
In Webster's Dictionary is an example of how to use “ceteris paribus “: [S]taple-growing states are, ceteris paribus, more favorable to slave labor than manufacturing states.” I suspect it would take a minor treatise to elucidate fully the ceteris paribus conditions here. And once this was done, it would be doubtful that holding all these cetera constant would have much analytical meaning. Unfortunately, this is always the potential problem with the expression. In too many cases one is unsure of exactly what restraints are being imposed and by what authority the exercise is legitimated. Fittingly, the history of ceteris paribus is a history of studied ambiguity.
