We develop a dynamic multi-country Ricardian trade model with aggregate uncertainty, where trade imbalances emerge as countries exchange goods and assets. We introduce a method for computing counterfactuals in this setting, which doesn't require specifying the stochastic process of shocks or solving for asset prices. Applying the model to tariff shocks, we quantify their effects on prices, income, spending, and trade imbalances. We find that higher U.S. tariffs reduce the U.S. trade deficit through general equilibrium adjustments, but raise domestic prices and lower real consumption. Our findings highlight that movements in trade imbalances are shaped by the structure of global trade and finance, and that attempts to influence external balances through changes in trade barriers carry significant implications for real economic outcomes.

This paper develops a complete-markets model to analyze the determinants of endogenous trade imbalances across countries. We introduce a framework where countries can trade in Arrow-Debreu securities to insure against different states of the world, which enables them to run deficits in some states and surpluses in others. The model allows for counterfactual analysis of various trade policy scenarios, such as unilateral tariff impositions. We derive the conditions under which trade deficits arise endogenously and discuss implications for welfare and trade policy analysis.

We model the world economy as one system of endogenous input-output relationships subject to frictions and study how the world's input-output structure and world's GDP change due to changes in frictions. We derive a sufficient statistic to identify frictions from the observed world input-output matrix, which we fully match for the year 2011. We show how changes in internal frictions impact the whole structure of the world's economy and that they have a much larger effect on world's GDP than external frictions. We also use our approach to study the role of internal frictions during the Great Recession of 2007–2009.

Using employer-employee matched and firm production quantity and input data for Portuguese firms, we study the endogenous response of productivity to firm reorganizations as measured by changes in the number of management layers. We show that, as a result of an exogenous demand or productivity shock that makes the firm reorganize and add a management layer, quantity-based productivity increases by about 6%, while revenue-based productivity drops by around 3%. Such a reorganization makes the firm more productive but also increases the quantity produced to an extent that lowers the price charged by the firm and, as a result, its revenue-based productivity as well.

We use a comprehensive dataset of French manufacturing firms to study their internal organization. We first divide the employees of each firm into ‘layers’ using occupational categories. Layers are hierarchical in that the typical worker in a higher layer earns more, and the typical firm occupies less of them. In addition, the probability of adding (dropping) a layer is very positively (negatively) correlated with value added. We then explore the changes in the wages and number of employees that accompany expansions in layers, output, or markets (by becoming exporters). The empirical results indicate that reorganization, through changes in layers, is key to understand how firms expand and contract. For example, we find that firms that expand substantially add layers and pay lower average wages in all pre-existing layers. In contrast, firms that expand little and do not reorganize pay higher average wages in all pre-existing layers.
