1. Performance standards are preferable to technology standards in that they give some flexibility to firms in terms of achieving a given amount of emissions reduction.

2.Emissions taxes are preferable to trade able emissions permits in that the revenue from taxes can be used to reduce other distortionary taxes (e.g., income taxes), leading to what is known as a double dividend for society.

3. If there are transactions costs in a trade able permit market, the ultimate distribution of trade able permits held by firms in the market will depend upon the initial allocation of permits.

4.All else equal, in the case of an ambient pollution problem, a cost effective regulatory scheme (either a tax or traceable permit system) will require firms with lower transfer coefficients to achieve a lower level of overall emissions compared to an otherwise identical firm with a higher transfer coefficient.
