How to explain rising income and wealth inequality? We build an original heterogeneous-agent model with three key features: (i) an explicit link between firm's market power and top income shares, (ii) a granular representation of the tax and transfer system, and (iii) three assets with...

A matching model with labor/leisure choice and bargaining frictions is used to explain (i) differences in GDP per hour and GDP per capita, (ii) differences in employment, (iii) differences in the proportion of part-time work across countries. The model predicts that the higher the level of...

While most of the literature on employment protection has focused on government-mandated severance pay, it has recently been documented that a substantial share of severance payments derives from private contracts or collective agreements. This paper studies the determination of these payments....

In this paper, we investigate the causes and consequences of "unclaimed" unemployment insurance (UI) benefits. A search model is developed where the costs to collecting UI benefits include both a traditional "fixed" administrative cost and an endogenous cost arising from worker and firm...

Recent data show substantial increases in the size of gross external asset and liability positions. The implications of these developments for optimal conduct of monetary policy are analyzed in a standard open economy model which is augmented to allow for endogenous portfolio choice. The model...

This paper develops a model of endogenous exchange rate pass-through within an open economy macroeconomic framework, where both passthrough and the exchange rate are simultaneously determined, and interact with one another. Pass-through is endogenous because firms choose the currency in which...

This paper investigates the impact of market structure on the joint determination of exchange rate pass-through and currency of invoicing in international trade. A novel feature of the study is the focus on market share of firms on both sides of the market - that is, exporting firms and...

Countries that specialize in commodity exports often exhibit a correlation between the relevant commodity price and the value of their currency. We explore a natural but little-studied explanation for this correlation. An increase in the commodity price leads to increases in the future values of...

A well-known feature of one-good, multi-agent, Arrow-Debreu economies with identical additively-separable, homothetic preferences is that the consumptions of all agents are perfectly correlated. Such economies are widely used in interpreting business cycles but seem to be inconsistent with...
