We study the welfare implications of uncertainty in business cycle models. In the modern business cycle literature, multiplicative real shocks to production and/or preferences play an important role as the impulses that produce aggregate fluctuations. Introducing shocks in this way has the...

We demonstrate that inference from estimated structural News Driven Business Cycle (NDBC) models about the main drivers of fluctuations in macroeconomic variables and asset prices is sensitive to assumptions about the structure of the news shock processes. We show that, when data on asset prices...

This paper analyzes and computes the equilibria of economies with large numbers of heterogeneous agents who have different asset trading technologies, preferences and beliefs. We illustrate the value of our method by using it to evaluate the implications of these heterogeneities through several...

In this paper we characterize and estimate the degree to which liquidity constraints affect real activity. We set up a dynamic model of firm investment and debt in which liquidity constraints enter explicitly into the firm's maximization problem, so that investment depends positively on the...

The papers in this volume study nine depressions - both from the interwar period in Europe and America and from more recent times and Latin America - using a common framework. All of the papers rely on growth accounting to decompose changes in output into the portions due to changes in factor...

This paper proposes a measure of the welfare cost of volatility derived from a stochastic endogenous growth model extended to the case of a recursive utility function which disentangles risk aversion from intertemporal elasticity of substitution. The measure of the welfare cost of volatility...

We extend the basic RBC model to allow for biased technical changes. One broad definition of biased technical changes is changes that directly affect factor elasticities. Given the link between changes in factor elasticities and factor shares, observed fluctuations in US labor's share are...

Many asset pricing puzzles can be explained when habit formation is added to standard preferences. We show that utility functions with a habit then gives rise to a puzzle of consumption volatility in place of the asset pricing puzzles when agents can choose consumption and labor optimally in...

This paper considers transition dynamics associated with a change in the rate of technological progress, using a general equilibrium framework that incorporates stochastic technology growth trends. The model suggests that these dynamics are associated with protracted transition periods,...

This paper reexamines the "cost of business cycle" calculations made by Lucas ("Models of Business Cycles," Basil Blackwell, New York, 1987) and Imrohoroglu (J. Polit. Econ. 97 (1989), 1364-1383) under alternative specifications of individuals' risk preferences and using alternative...
