	This paper compares price
and quantity competition in a mixed duopoly with emission tax; in a mixed
duopoly, one public firm competes with one private firm in the market. We find
that social welfare is the highest when both the firms simultaneously choose
price levels. Then, the optimal emission tax is sufficiently lower than the
marginal social damage.
