New Study Reveals Federal Reserve Banks' Cost of Equity Capital
The Federal Reserve Banks need to figure out how much it costs them to provide payment services, including a cost of equity capital. Different methods were used to estimate this cost, but the standard CAPM model with a big group of similar companies gave the most accurate result. Narrowing down the group or adding more factors didn't make a big difference. So, using the standard CAPM model is a good way to estimate the cost of equity capital for the Reserve Banks.
