New Evidence on the US Excess Return on Foreign Portfolios
We provide new estimates of the return on US external claims and liabilities using confidential, high-quality, security-level data. The excess return is positive on average, since claims are tilted toward higher-return equities. The excess return is large and positive in normal times but large and negative during global crises, reflecting the global insurance role of the US external balance sheet. Controlling for issuer's nationality, we find that US investors have a larger exposure to equity issued by Asia-headquartered corporations than reported in the aggregate statistics. Finally, equity ...

The Global (Mis)Allocation of Capital
The allocative efficiency of capital flows is one of the oldest and most contentious questions. We answer it by matching cross-border securities holdings reported in the US external statistics from 1995 to 2022 with the corresponding firm-level measures of allocative efficiency. We find that US investors tilt their international equity investment toward firms with high MRPK and markups, thereby fostering their potential for growth. Foreign investors tilt their holdings toward US firms with high productivity and intangible capital. A horse race shows that productivity is the best predictor of ...

Ramsey monetary policy and international relative prices
We analyze welfare maximizing monetary policy in a dynamic two-country model with price stickiness and imperfect competition. In this context, a typical terms of trade externality affects policy interaction between independent monetary authorities. Unlike the existing literature, we remain consistent to a public finance approach by an explicit consideration of all the distortions that are relevant to the Ramsey planner. This strategy entails two main advantages. First, it allows an accurate characterization of optimal policy in an economy that evolves around a steady-state which is not ...

Dynamic Labor Reallocation with Heterogeneous Skills and Uninsured Idiosyncratic Risk
Occupational specificity of human capital motivates an important role of occupationalreallocation for the economy’s response to shocks and for the dynamics of inequality.We introduce occupational mobility, through a random choice model with dynamicvalue function optimization, into a multi-sector/multi-occupation Bewley (1980)-Aiyagari (1994) model with heterogeneous income risk, liquid and illiquid assets, priceadjustment costs, and in which households differ by their occupation-specific skills.Labor income is a combination of endogenous occupational wages and idiosyncraticshock. ...

Financial globalization, financial frictions and optimal monetary policy
How should monetary policy be optimally designed in an environment with high degrees of financial globalization? To answer this question we lay down an open economy model where net lending toward the rest of the world is constrained by a collateral constraint motivated by limited enforcement. Borrowing is secured by collateral in the form of durable goods whose accumulation is subject to adjustment costs. We demonstrate that, although this economy can generate persistent current account deficits, it can also deliver a stationary equilibrium. The comparison between different monetary policy ...

Cross-border resolution of global banks
Most recent regulations establish that resolution of global banking groups shall be done according to bail-in procedures and following a Single Point of Entry (SPE) as opposed to a Multiple Point of Entry (MPE) approach. The latter requires parent holding of global groups to put up front the equity capital needed to absorb losses possibly emerging in foreign subsidiaries branches. No model rationalized so far such resolution regime. We build a model of optimal design of resolution regimes and compare three regimes: SPE with cooperative authorities, SPE with non-cooperative authorities and MPE ...
