How Do Banks Set Interest Rates?
The aim of this paper is to study cross-sectional differences in banks interest rates. It adds to the existing literature in two ways. First, it analyzes in a systematic way both micro and macroeconomic factors that influence the price setting behavior of banks. Second, by using banks' prices (rather than quantities) it provides an alternative way to disentangle loan supply from loan demand shift in the bank lending channel' literature. The results, derived from a sample of Italian banks, suggest that heterogeneity in the banking rates pass-through exists only in the short run. Consistently with the literature for Italy, interest rates on shortterm lending of liquid and well-capitalized banks react less to a monetary policy shock. Also banks with a high proportion of long-term lending tend to change their prices less. Heterogeneity in the pass-through on the interest rate on current accounts depends mainly on banks' liability structure. Bank's size is never relevant.
