The analyses of implications for international public finance policy recommendations in the presence of unemployment and environmental problems.

解决环境问题通常涉及税收和其他政策工具。我们参加了有关失业救济金影响的讨论。它表明，只要失业救济金与有竞争力的工资挂钩，并通过使用平衡预算发生率分析，由企业所得税提供资金，失业救济金就可以很好地降低失业率。因此，我们有一个强有力的论据来证明失业救济金的反直觉效应。从经济学家的角度来看，环境问题可以分为两类。第一个问题包括与环境税改革有关的问题。第二类解决了与外部性相关的最优税收问题。我们重新审视了外部性存在下的最优税收问题。效率限制了污染税的水平，从而产生收入，这样我们就可以降低扭曲经济运行的消费商品的税率。因此，这些污染税可以减少过度的污染，这些收入也可以用于失业救济金。这些公共政策可以减少失业劳动力。

Addressing environmental issues typically involves taxs and other policy instruments. We have taken part in the discussion regarding the effects of unemployment benefits. It has shown that unemployment benefits may well decrease unemployment as long as these are indexed by the competitive wage and are financed by the corporate income tax, via using the balanced budget incidence analysis. Hence, we have a strong argument of counter-intuitive effects of unemployment benefits.From economists' standpoint, environmental issues can be divided into two categories. The first one consists of the issues associated with environmental tax reforms. The second category addresses optimal tax problems associated with externalities. We reexamined the optimal tax problems in the presence of externalities. Efficiency restrain levels of polluting taxs generate revenues so that we can reduce rates on consumption commodities that distort the functioning of the economy. So these polluting taxs can reduce excessive levels of pollution and also these revenues can use unemployment benefits. These public policies can decrease unemployment labors.
