Is it true? Please, explain in a VERY detailed way. If the price of money (e.g., interest rates and equity capital costs) increases due to an increase of anticipated inflation, the risk-free rate will also increase. If there is no change in investment aversion, then the market risk premium (r_M - r_RF) will remain constant. Also if there is change in stocks' betas, then the required rate of return on each stock as measured by will increase by the same amount as the increase in expected inflation.
