In this paper, I introduce lumpy micro-level capital adjustment into a sticky information general equilibrium model. Lumpy adjustment arises because of inattentiveness in capital investment decisions instead of the more common assumption of non-convex adjustment costs. The model features...

Macroeconomic and sector-specific shocks exert differential effects on investment in disaggregate sectoral data. The response to macroeconomic shocks is hump-shaped, just as in aggregate data. The effects of sectoral innovations decrease monotonically. A calibrated model of investment with...

This paper studies the dynamic effects of an uncertainty shock on firm expectations. We conduct a survey that confronts managers from a representative firm sample with a model-consistent uncertainty shock scenario. An exogenous increase in uncertainty significantly reduces managers' expected...

We explore the implications of shocks to expected future productivity. In a setting with limited enforcement of financial contracts, firms have to post collateral to obtain external finance. In a real one-sector model with this type of "collateral constraint", positive news about future...

As the millennium draws to an end, the threat posed by the Year 2000 (Y2K) computer problem is inducing vast private and public spending on its remediation. In this paper, we model the Y2K problem as an anticipated, permanent loss in output whose magnitude can be lessened by investing resources...

This paper develops a dynamic stochastic general equilibrium model with putty-clay technology that incorporates embodied technology, investment irreversibility, and variable capacity utilization. Low short-run capital-labor substitutability native to the putty-clay framework induces the...

This paper studies the macroeconomic effects of shocks to idiosyncratic business risk in an economy with endogenously incomplete markets. I develop a model in which firms face idiosyncratic risk and obtain insurance from intermediaries through contracts akin to credit lines. Insurance is...
