摘要：Extending a standard 2x2 Heckscher-Ohlin model to incorporate emissions, this paper investigates the effect of differentiated emission taxes on output and emissions in a small open economy. The following results are derived. First, raising the emission tax imposed on one industry may increase the output of that industry. This result is quite surprising in the sense that such a paradoxical result can occur in a simple and standard model under fairly plausible values of parameters. By numerical examples and using a graphical method, it is also shown that the mechanism behind the result is the factor market adjustment effects which work through two different channels. Second, while strengthening emission taxes uniformly across industries always reduces the volume of emissions, strengthening emission tax unevenly may increase it.
