Standard models used for monetary policy analysis rely on sticky prices. Recently, the literature started to explore also nominal debt contracts. Focusing on mortgages, this paper compares the two channels of transmission within a common framework. The sticky price channel is dominant when...

The financial crisis of 2007-9 has sparked keen interest in models of financial frictions and their impact on macro activity. Most models share the feature that borrowers suffer a contraction in the quantity of credit. However, the evidence suggests that although bank lending to firms declines...

Standard banking theory suggests that there exists an optimal level of credit risk that yields maximum bank profit. We identify the optimal level of risk-weighted assets that maximizes banks’ returns in the full sample of US banks over the period 1996–2011. We find that this optimal level is...

The cheapest way for banks to finance long term illiquid projects is typically to borrow short term from households. But when household needs for funds are high, interest rates will rise sharply, debtors will have to shut down illiquid projects, and in extremis, will face more damaging runs....

A firm's termination generates bankruptcy costs. This may create incentives for a firm's owner to bail out a firm in bankruptcy and to curb the firm's risk taking outside bankruptcy. We analyze the role of such implicit guarantees in the context of financial institutions that sponsor money...

Although long obscured by the Great Depression, the nationwide "bubble" that appeared in the early 1920s and burst in 1926 was similar in magnitude to the recent real estate boom and bust. Fundamentals, including a post-war construction catch-up, low interest rates and a "Greenspan put," helped...

Using individual-level data on homeowner debt and defaults from 1997 to 2008, we show that borrowing against the increase in home equity by existing homeowners is responsible for a significant fraction of both the sharp rise in U.S. household leverage from 2002 to 2006 and the increase in...

Monetary policy has real effects through credit supply and demand, and since these changes are mostly unobserved, the complete identification of the credit channel is generally unfeasible. Bank lending surveys by central banks, however, contain reliable quarterly information on changes in loan...

We explore the structural drivers of bank and nonbank credit cycles using an estimated medium-scale macro model that allows for bank and nonbank financial intermediation. We posit economy-wide aggregate and sectoral disturbances to potentially drive bank and nonbank credit growth. We find that...

After many years, many critiques, and many variations, the staggered wage and price setting model is still the most common method of incorporating nominal rigidities into empirical macroeconomic models used for policy analysis. The aim of this chapter is to examine and reassess the staggered...
