Incomplete Information and Irreversible Investment
How do information frictions and investment frictions interact? We use a continuous-time model to analytically characterize how incomplete information distorts firms’ decision rules and stationary distribution when investment is irreversible. The two frictions interact in rich and substantial ways. At the firm level, noisier information shrinks a firm’s inaction region and reduces the elasticity of investment to productivity. In the aggregate, incomplete information increases steady-state capital, exacerbates capital misallocation, and mitigates the impact of productivity shocks on ...

The Macroeconomics of Irreversibility
We study aggregate capital dynamics in an investment model with idiosyncratic productivity shocks, fixed capital adjustment costs, and irreversibility driven by a wedge between capital purchase and resale prices. We derive sufficient statistics capturing the role of investment frictions on aggregate capital fluctuations, measure these statistics with investment microdata, and exploit them to discipline the capital price wedge. Irreversibility doubles the persistence of capital fluctuations and is crucial for reconciling micro-level investment behavior with macroeconomic propagation.
