This paper proposes a structural explanation for a news shock. My hypothesis is that a surprise, research and development sector-specific productivity shock may be identified and labeled as news by prominent empirical research in the literature. To examine this hypothesis, I construct a simple...

This paper studies a model that includes investment-specific technological shocks, a variable capacity utilization rate, and endogenous product entry subject to sunk product development costs. These factors constitute a powerful amplification mechanism as they interact with each other. The model...

This paper proposes an approximate solution of firm's optimal inattentive length in a standard macroeconomic model. The approximate solution conceptually fits a sticky-information model better, and predicts empirically more plausible inattentive length than the one proposed by Reis (2006)

We review the current state of the estimation of DSGE models. After introducing a general framework for dealing with DSGE models, the state-space representation, we discuss how to evaluate moments or the likelihood function implied by such a structure. We discuss, in varying degrees of detail,...

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

We propose a novel method to estimate dynamic equilibrium models with stochastic volatility. First, we characterize the properties of the solution to this class of models. Second, we take advantage of the results about the structure of the solution to build a sequential Monte Carlo algorithm to...
