<P>我想,是不是可以考虑分析下面两种情况(2 goods:Park and another consumption good):</P>
<P>1、Provision of public services by government funded decentralized agencies。为简便起见,也可以假定centralized angency,也就是只有一个agency的情况;</P>
<P>2、Private provision or market allocation。</P>
<P>如果想把model做的更复杂和精细一些,可以假设:(1)agencies/firms have different cost conditions,and(2)the government has imperfect information about the agencies' cost conditions;(3)different types of individuals (different income)with identical/different preference。</P>
<P>这是我的一点初步考虑,如果你有其它想法,咱们再讨论。</P>
