December 2013Mortgages and Monetary Policy
with Carlos Garriga, Finn E. Kydland: w19744
Mortgage loans are a striking example of a persistent nominal rigidity. As a result, under incomplete markets, monetary policy affects decisions through the cost of new mortgage borrowing and the value of payments on outstanding debt. Observed debt levels and payment to income ratios suggest the role of such loans in monetary transmission may be important. A general equilibrium model is developed to address this question. The transmission is found to be stronger under adjustable- than fixed-rate contracts. The source of impulse also matters: persistent inflation shocks have larger effects than cyclical fluctuations in inflation and nominal interest rates
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.
