Introducing Financial Frictions and Unemployment into a Small Open Economy Model
Lawrence J. Christiano, Mathias Trabandt, and Karl Walentin
CQER Working Paper 10-04 (August)
The authors extend the standard new Keynesian model by incorporating financial frictions in capital accumulation and management, modeling the labor market using a search and matching framework, and extending the model into a small open economy setting.
Involuntary Unemployment and the Business Cycle
Lawrence J. Christiano, Mathias Trabandt, and Karl Walentin
CQER Working Paper 10-03 (August)
When the authors integrate their model of involuntary unemployment into a DSGE model, the resulting model does well at accounting for standard macroeconomic variables' response to monetary policy shocks and two technology shocks.
DSGE Models for Monetary Policy Analysis
Lawrence J. Christiano, Mathias Trabandt, and Karl Walentin
CQER Working Paper 10-02 (August)
The paper describes and implements Bayesian moment matching and impulse response matching procedures to assign numerical values to parameters in DSGE models used for policy analysis.
When Is the Government Spending Multiplier Large?
Lawrence J. Christiano, Martin Eichenbaum, and Sergio Rebelo
CQER Working Paper 10-01 (August)
The authors argue that the government spending multiplier can be very large when the nominal interest rate is constant. For the economies they consider, it is optimal to increase government spending in response to shocks that make the zero lower bound on the nominal interest rate binding.

Optimal Prediction Pools
John Geweke and Gianni Amisano
CQER Working Paper 09-05 (October)
This study finds that linear pools of prediction models generally yield predictions superior to those of any single model as assessed by a conventional log score function.
Comparing and Evaluating Bayesian Predictive Distributions of Asset Returns
John Geweke and Gianni Amisano
CQER Working Paper 09-04 (October)
Using five different models, the authors compare and evaluate the quality of predictive distributions over multiple horizons for asset returns of the S&P 500 index from 1972 through 2005.
Sources of Variation in Holding Returns for Fed Funds Futures Contracts
James D. Hamilton and Tatsuyoshi Okimoto
CQER Working Paper 09-03 (October)
This paper investigates the extent to which changes in regime can account for predictable gains from positions in fed funds futures contracts.
Causes and Consequences of the Oil Shock of 2007–08
James D. Hamilton
CQER Working Paper 09-02 (October)
Exploring similarities and differences between the oil price run-up in 2007–08 and earlier oil price shocks, the author examines what caused the price increase and what effects it had on the economy.
Liquidity Needs in Economies with Interconnected Financial Obligations
Julio J. Rotemberg
CQER Working Paper 09-01 (July)
In this financial system model where firms must settle their debts using liquid assets, limits on the amount of liquid assets can lead to more defaults when financial firms are more interconnected.
