Romer’s principle objection is to the assumption that the only interaction allowable in economic growth models is what is known as “price taking,” the buying or selling of goods and services at the price currently offered by the market. I would add to that my objection to the assumption that individual decision-making is always characterized by rational expectations.
罗默的主要反对点是一个假设：经济增长模型中唯一允许的互动式所谓的“价格接受”，即买卖商品和服务在由市场提供的当前价格水平上进行。我要在此基础上增加我对另一个假设的反对：个体决策永远是理性预期的。
