to read through all four articles and I want you to use all the articles to address two key issues. First, try to formulate principles that would guide you in future decisions. What sorts of things should people be able to sell and buy in a market? What are the grounds for interfering with the rights of people to engage in transactions? Second, economists faced with a policy dispute invoke cost/benefit analysis. Further, for voluntary exchanges economists believe that the benefits must outweigh the costs, otherwise people wouldn't engage in the exchange. But if someone who has no money raises money by doing one of the things described in the article, is that voluntary? Are people always good judges of their interests? Could there be uneven bargaining power where people feel coerced into doing something?
