Cartel Pricing Dynamics in the Presence of an Antitrust Authority
研究企业在担心引发卡特尔怀疑时的定价行为，卡特尔可能逐步提价至稳态或先升后降，反垄断法反而可能使卡特尔更稳定、价格更高。
Cartel pricing is characterized when firms are concerned about creating suspicions that a cartel has formed. Balancing concerns about maintaining the stability of the cartel with those of avoiding detection, the cartel may either (i) gradually raise price to its steady-state level or (ii) gradually raise price and then have it decline to its steady-state level. Antitrust laws may have a perverse effect as they make cartel stability easier and thus allow for higher cartel prices.
