The Relative Rigidity of Monopoly Pricing

This paper seeks to explain why monopolies keep their nominal prices constant for longer periods than do tight oligopolies. We provide two possible explanations. The first is based on the presence of a small fixed cost of changing prices. The second, on small costs of discovering the optimal price.

本文旨在阐释为何相较于紧密型寡头企业，垄断企业会在更长时期内维持名义价格恒定。我们提出两种可行解释：其一基于价格调整存在小额固定成本；其二基于发现最优价格所需的小额成本。
