我们调查了一个生产过程产生排放的行业的私有化政策。我们发现，高度的负外部性导致了从公有企业到民营企业的生产替代。此外，我们还证明了，如果负外部性程度足够高，那么，即使市场中的企业数量很多，混合寡头垄断也比纯寡头垄断更有利于社会福利。此外，我们还考虑让私营企业自由进入。
We investigate the privatization policy of an industry where the production process generates emissions. We show that the high degree of negative externality leads to production substitution from the public firm to private firms. Moreover, we show that, if the degree of negative externality is sufficiently high, then a mixed oligopoly is preferable to a pure oligopoly for social welfare, even if the number of firms in the market is large. Furthermore, we consider free entry of private firms.
