Enduring Relationships in an Economy with Capital and Private Information
We study efficient risk sharing in a model where agents operate linear production technologies with private information about idiosyncratic productivity. Capital is the sole factor of production, and accumulable. We establish a time-invariant, one-to-one mapping between the capital allocated to an agent and his lifetime utility entitlement. The mapping implies properties that are distinct from those in models with private information about endowments. In contrast to the latter, the value of the risk-sharing arrangement in our model always remains above the autarky value. There is no need for ...

Capital Accumulation and Dynamic Gains from Trade
We compute welfare gains from trade in a dynamic, multicountry model with capital accumulation. We examine transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization. Both the relative price of investment and the investment rate respond to changes in trade frictions. Relative to a static model, the dynamic welfare gains in a model with balanced trade are three times as large. The gains including transition are 60 percent of those computed by comparing only steady states. Trade imbalances have negligible effects on the cross-country distribution of ...

Trade Integration, Global Value Chains, and Capital Accumulation
Motivated by increasing trade and fragmentation of production across countries since World War II, we build a dynamic two-country model featuring sequential, multi-stage production and capital accumulation. As trade costs decline over time, global-value-chain (GVC) trade expands across countries, particularly more in the faster growing country, consistent with the empirical pattern. The presence of GVC trade boosts capital accumulation and economic growth and magnifies dynamic gains from trade. At the same time, endogenous capital accumulation shapes comparative advantage across countries, ...

Default Risk, Sectoral Reallocation and Persistent Recessions
Sovereign debt crises are associated with large and persistent declines in economic activity, disproportionately so for nontradable sectors. This paper documents this pattern using Spanish data and builds a two-sector dynamic quantitative model of sovereign default with capital accumulation. Recessions are very persistent in the model and more pronounced for nontraded sectors because of default risk. An adverse domestic shock increases the likelihood of default, limits capital in?ows, and thus restricts the ability of the economy to exploit investment opportunities. The economy responds by ...
