We study welfare gains from trade in a dynamic, multicountry model with capital accumulation. We compute the exact transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization. We find that while the dynamic gains are different across countries,...

Why did the marriage probability of single females in France after World War 1 rise 50% above its pre-war average, despite a 33% drop in the male/female singles ratio? We conjecture that war-time disruption of the marriage market generated an abnormal abundance of men with relatively high...

International trade in capital goods has quantitatively important effects on economic development through capital formation and TFP. Capital goods trade enables poor countries to access more efficient technologies, leading to lower relative prices of capital goods and higher capital-output...

We examine homeowner vacancy rates over time and space using Markov-switching models. Our theoretical analysis extends the Wheaton (1990) search and matching model for housing by incorporating regime-switching behavior and interregional spillovers. Our approach is strongly supported by our...

A key property of the Aiyagari-type heterogeneous-agent models is that the equilibrium interest rate of public debt lies below the time discount rate. This fundamental property, however, implies that the Ramsey planner's fiscal policy may be time-inconsistent because the forward-looking planner...

In this paper, we estimate the effect of defense spending on the U.S. macroeconomy since World War II. First, we construct a new panel dataset of state-level federal defense contracts. Second, we sum observations across states and, using the resulting time series, estimate the aggregate effect...

In response to the COVID-19 pandemic, Latin American countries temporarily suspended rules limiting debt, fiscal and monetary policies. Despite this increase in flexibility, the crisis implied a substantial deterioration of macroeconomic variables (e.g., real GDP declined by 9.5%) and high...

We build a tractable heterogeneous-agent incomplete-markets model with quasi-linear preferences to address a set of long-standing issues in the optimal Ramsey taxation literature. The tractability of our model enables us to analytically prove the existence of a Ramsey steady state and establish...

The aggregate capital stock in a nation can be overaccumulated for many different reasons. This paper studies which policy or policy mix is more effective in achieving the socially optimal (golden rule) level of aggregate capital stock in an infinite-horizon heterogeneous-agents...

The rapidly growing national debt in the U.S. since the 1970s has alarmed and intrigued the academic world. Consequently, the concept of dynamic (in)efficiency in an overlapping generations (OLG) world and the importance of the heterogeneous-agents and incomplete markets (HAIM) hypothesis to...
