December 2013Mortgages and Monetary Policy
with Carlos Garriga, Finn E. Kydland: w19744
Mortgages are prime examples of long-term nominal loans. As a result, under incomplete asset markets, monetary policy can affect household decisions through the cost of new mortgage borrowing and the value of payments on outstanding debt. These channels are distinct from the transmission through real interest rates. A stylized general equilibrium model incorporating these features is developed. Persistent monetary policy shocks, resembling the level factor in the nominal yield curve, have larger real effects than transitory shocks. The transmission is stronger under adjustable- than fixed-rate mortgages. Higher, persistent, inflation benefits homeowners under FRMs but hurts them under ARMs.
October 2012Housing Dynamics over the Business Cycle
with Finn E. Kydland, Peter Rupert: w18432
Over the U.S. business cycle, fluctuations in residential investment are well known to systematically lead GDP. These dynamics are documented here to be specific to the U.S. and Canada. In other developed economies residential investment is broadly coincident with GDP. Nonresidential investment has the opposite dynamics, being coincident with or lagging GDP. These observations are in sharp contrast with the properties of nearly all business cycle models with disaggregated investment. Including mortgages and interest rate dynamics aligns the theory more closely with U.S. observations. Longer time to build in housing construction makes residential investment coincident with output.
July 2009Globally Correlated Nominal Fluctuations
with Espen Henriksen, Finn E. Kydland: w15123
Cyclical fluctuations in nominal variables--aggregate price levels and nominal interest rates--are documented to be substantially more synchronized across countries than cyclical fluctuations in real output. A transparent mechanism that can account for this striking feature of the nominal environment is highlighted. It is based on (small) cross-country spillovers of shocks and an interaction between Taylor rules and no-arbitrage conditions. The mechanism is quantitatively important for a wide range of plausible parameterizations and is found to be robust to modifications of the economic environment that help account for other important features of domestic and international aggregate fluctuations.
