We study how total factor productivity (TFP), energy prices, and the Great Moderation are linked. First we estimate a joint stochastic process for the energy price and TFP and establish that until the second quarter of 1982, energy prices negatively affected productivity. This spillover has...

Can a DSGE model replicate the financial crisis effects without assuming unprecedented and implausibly large shocks? Starting from the assumption that the subprime crisis triggered the financial crisis, we introduce balance-sheet effects for housing market borrowers and for commercial banks in...

Motivated by a recent demographic study establishing a link between macroeconomic fluctuations and the mortality index kt in the Lee-Carter model, we develop a dynamic asset-liability model to assess the impact of macroeconomic fluctuations on the solvency of a life insurance company....

This paper examines the stochastic properties of aggregate macroeconomic time series from the standpoint of fractionally integrated models, and focuses on the persistence of economic shocks. We develop a simple macroeconomic model that exhibits long-term dependence, a consequence of aggregation...

This chapter describes the recently developed policy evaluation techniques. It focuses on discrete time stochastic models and on relating the policy evaluation methods to the geometric approach commonly used in theoretical continuous time models. The exposition centers on a number of specific...

This paper argues that a specification of stochastic volatility commonly used to analyze the Great Moderation in DSGE models may not be appropriate, because the level of a process with this specification does not have conditional or unconditional moments. This is unfortunate because agents may...
