Abstract

Merton (1990, p.44) claims that the market portfolio can be constructed without the knowledge of preferences and the distribution of wealth. However, the analytical equilibrium solution to the CAPM market reveals that it is not true. Investors' preferences and wealth affect the equilibrium price of the market, they do not affect the mathematical form of the CAPM formula, but change the values of the variables in the formula.
