摘要: Abstract This paper reports an experiment conducted to examine the effects of changing form strategic interactions (Bertrand or Cournot), and underlying information conditions on usefulness ‘ALM,’ a merger simulation device used by US Department Justice. The consists 20, 60-period quadropolies. After period 40 is induced. Behaviorally, Cournot markets are much more variable than Bertrand markets. Also, providing about others’ actions earnings dampens merger-related comparative statics effects. Consequently, ALM predicts post-merger performance poorly. Nevertheless, results do not undermine previous finding that screens out nonproblematic consolidations.
