The Macroeconomics of Irreversibility

Isaac Baley and Julio Andrés Blanco

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 that capture the role of investment frictions in aggregate capital fluctuations, measure these statistics using investment microdata, and exploit them to discipline the capital price wedge.

Devaluations, Deposit Dollarization, and Household Heterogeneity

Francesco Ferrante and Nils Gornemann

We study the aggregate and redistributive effects of currency devaluations in a small open economy model with leverage-constrained banks and heterogeneous households. Our framework captures three stylized facts about financial dollarization in emerging economies: i) a sizable share of domestic deposits is denominated in foreign currency; ii) these deposits represent significant foreign currency liabilities for local banks; and iii) dollar deposits are mainly held by wealthier households.

Bridges

Anna Tompsett

Bridges are critical but sparse links in land transport networks. I exploit quasi-experimental variation in bridge construction over major rivers in the United States to measure the causal effects of land transport infrastructure. Bridges are more often built upstream than downstream of tributary confluences—where smaller rivers join larger rivers—generating local differences in connectivity. These local connectivity advantages have negative effects on per capita income.

Supply-side climate policies in the oil market: Higher taxes reduce exploration and discoveries. If only OECD countries adopt this policy, 47–73% is offset by non-OECD countries.

"We prove a CLT for strategic network formation with homophilous agents. This enables inference on statistics derived from a single large network. We discuss practical procedures."
