R＆D Competition under Mixed Duopoly:Perspectives of Uncertainty and ImitationChinese Full Text

JI Sheng-bao XIAN Guo-ming

Abstract: Using δ ’as parameter measuring R＆D imitation,this paper extends Theotoky（1998）’s study and confirms the robustness of Theotoky’s conclusions.Besides,bringing in a quadratic R＆D cost function,the paper suggests that depending on innovation size ‘P’ and imitation parameter ‘ δ ’,welfare comparing between mixed duopoly and private duopoly is ambiguous.That is,（1） for all d,the larger the innovation size is,the more possible private duopoly tends to dominate mixed duopoly,and only with lower P can mixed duopoly prevail;（2） for lower P,only together with higher d,can mixed duopoly prevail;（3） for d≠1,during δ ’s increasing process,the higher（lower） the interest rate is,the more possible the minimum value of P required for private duopoly’s dominance becomes larger（smaller） initially and then smaller（larger）.
