This essay will discuss the criticisms of the economic approach to markets offered by Michael Sandel's What Money Can't Buy. After reviewing the main arguments, the essay looks at these from three main angles. First, it relates them to different traditions of thinking about markets and their achievements that have been developed by economists. Second, it discusses the idea that markets can change values as argued by Sandel in light of recent related literature in economics. Third, it discusses some of the literature on alternatives to using the market to allocate resources and the pros and cons of these. (JEL A11, A13, D40, D63, P10)

This paper argues that the possibility of bailouts to financial intermediaries distorts the supply price of capital and creates an argument for taxing financial bonuses separately from other sources of income. We develop a model of financial contracting where intermediaries compete for workers whose actions affect productivity and risk-taking in the financial sector. This derives the second-best optimum and market equilibrium. The optimal taxes that we propose increase both equity and efficiency compared to the pure market outcome.
