internalized industry costs and usually 

 must be forced on industry. 



There would, of course, be much 

 debate over the magnitude and structure 

 of the tax. The tax structure should be 

 tied to the direct and indirect total 

 (social) costs of the toxic material. 

 There is currently much uncertainty 

 about these costs, but a tax system does 



not require perfect information to be 

 workable and effective. A tax system 

 could also provide funding for addi- 

 tional research into these costs and 

 produce more accurate taxation with 

 time. If the environment of the MDPR 

 and the rest of the country is to be 

 managed effectively, more of this kind 

 of research and the means to implement 

 results are needed.
