Coase on broadcasting, advertising and policy
指出科斯在广播研究中以“欲望”为基础的政策观限制了其分析，并探讨了区分“欲望”与“需求”如何为更广泛的政策评估框架提供可能。
The initial argument developed in this paper is that a wants-based conception of the objectives of policy, clearly operative in his broadcasting studies, together with the acceptance of certain assumed properties of the competitive process, tightly constrain Coase's work. At times, for example, when considering the impact of advertising, Coase accepts that the assessment of policy must be carried out on a broader basis. Coase does not, however, go on to develop a criterion beyond wants. Elsewhere, he highlights the importance of the distinction between wants and needs. This paper further argues that, by elaborating upon this distinction, it becomes possible to give an indication of how a broader framework for the assessment of policy might be developed.
