The geography of wealth: shocks, mobility, and precautionary savings
The spatial distribution of wealth in the United States is very heterogeneous, with important differences within and across US states. We study the distribution of wealth in a country and how it is shaped by the characteristics earnings across regions, and by the frictions individuals face to move and reallocate across space. For this, we develop a tractable model of consumption, savings, and location choice with many regions, incomplete markets, and heterogeneous agents facing persistent and transitory income shocks. Our analysis focuses on the role of income shocks, precautionary savings, ...

Geopolitical Oil Price Risk and Economic Fluctuations
This paper studies the general equilibrium effects of time-varying geopolitical risk in the oil market by simultaneously modeling downside risk from disasters, oil storage and the endogenous determination of oil price and macroeconomic uncertainty in the global economy. Notwithstanding the attention geopolitical events in oil markets have attracted, we find that geopolitical oil price risk is not a major driver of global macroeconomic fluctuations. Even when allowing for the possibility of an unprecedented 20 percent drop in global oil production, it takes a large increase in the probability ...

Household Excess Savings and the Transmission of Monetary Policy
Household savings rose above trend in many developed countries after the onset of COVID-19. Given its link to aggregate consumption, the presence of these "excess savings" has raised questions about their implications for the transmission of monetary policy. Using a panel of euro-area economies and high-frequency monetary policy shocks, we document that household excess savings dampen the effects of monetary policy on economic activity and inflation, especially during the pandemic period. To rationalize our empirical findings, we build a New Keynesian model in which households use savings to ...

Geopolitical Oil Price Risk and Economic Fluctuations
This paper seeks to understand the general equilibrium effects of time-varying geopolitical risk in oil markets. Answering this question requires simultaneously modeling several features including macroeconomic disasters and geopolitically driven oil production disasters, oil storage and precautionary savings, and the endogenous determination of uncertainty about output and the price of oil. We find that oil price uncertainty tends to be driven by macroeconomic uncertainty. Shifts in the probability of a geopolitically driven major oil supply disruption have meaningful effects on the price of ...

The impact of medical and nursing home expenses and social insurance
We consider a life-cycle model with idiosyncratic risk in earnings, out-of-pocket medical and nursing home expenses, and survival. Partial insurance is available through welfare, Medicaid, and social security. Calibrating the model to the United States, we show that (1) savings for old-age, out-of-pocket expenses account for 13.5 percent of aggregate wealth, half of which is due to nursing home expenses; (2) cross-sectional out-of-pocket nursing home risk accounts for 3 percent of aggregate wealth and substantially slows down wealth decumulation at older ages; (3) the impact of medical and ...

Macroeconomic Volatility and External Imbalances
Does macroeconomic volatility/uncertainty affect accumulation of net foreign assets? In OECD economies over the period 1970-2012, changes in country specific aggregate volatility are, after controlling for a wide array of factors, significantly positively associated with net foreign asset position. An increase in volatility (measured as the standard deviation of GDP growth) of 0.5% over period of 10 years is associated with an increase in the net foreign assets of around 8% of GDP. A standard open economy model with time varying aggregate uncertainty can quantitatively account for this ...

Spillovers and Spillbacks
We study international monetary policy spillovers and spillbacks in a tractable two-country Heterogeneous Agent New Keynesian model. Relative to Representative Agent (RANK) models, our framework introduces a precautionary-savings channel, as households in both countries face uninsurable income risk, and a real-income channel, as households have heterogeneous marginal propensities to consume (MPC). While both channels amplify the size of spillovers/spillbacks, only precautionary savings can change their sign relative to RANK. Spillovers are likely to be larger in economies with higher ...

Approximately Right?: Global v. Local Methods for Open-Economy Models with Incomplete Markets
Global and local methods are widely used in international macroeconomics to analyze incomplete-markets models. We study solutions for an endowment economy, an RBC model and a Sudden Stops model with an occasionally binding credit constraint. First-order, second-order, risky steady state and DynareOBC solutions are compared v. fixed-point-iteration global solutions in the time and frequency domains. The solutions differ in key respects, including measures of precautionary savings, cyclical moments, impulse response functions, financial premia and macro responses to credit constraints, and ...

Precautionary Volatility and Asset Prices
Many theories of asset prices assume time-varying uncertainty in order to generate time-varying risk premia. This paper generates time-varying uncertainty endogenously, through precautionary saving dynamics. Precautionary motives prescribe that, in bad times, next period's consumption should be very sensitive to news. This time-varying sensitivity results in time-varying consumption volatility. Production makes this channel visible, and external habit preferences amplify it. An estimated model featuring this channel quantitatively accounts for excess return and dividend predictability ...
