Why Do Households Save and Work?
This paper develops and estimates a dynamic life-cycle model to quantify why households save and work. The model incorporates multiple sources of risk—health, marital status, wages, medical expenses and mortality—as well as endogenous labor supply and human capital accumulation, retirement, and bequest motives at the death of the first and last household member. We estimate it using PSID and HRS data for the 1941–1945 cohort via the Method of Simulated Moments. Eliminating bequest motives reduces aggregate wealth by 23.8% and labor earnings by 1.2%; removing medical expenses lowers them ...

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 ...

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 ...

Breaking the “Iron Rice Bowl” and Precautionary Swings: Evidence from Chinese State-Owned Enterprises Reform
We use China?s large-scale reform of state-owned enterprises (SOE) in the late 1990s as a natural experiment to identify and quantify the importance of precautionary savings for wealth accumulation. Before the reform, SOE workers enjoyed the same job security as government employees. After the reform, a cumulative of over 35 million SOE workers have been laid off, although government employees kept their ?iron rice bowl.? The change in unemployment risks for SOE workers relative to that of government employees before and after the reform provides a clean identification of income uncertainty ...

Firms’ Precautionary Savings and Employment during a Credit Crisis
Can the macroeconomic effects of credit supply shocks be large even when a small share of firms are credit-constrained? I use U.K. firm-level accounting data to discipline a heterogeneous-firm model where the interaction between real and financial frictions induces precautionary cash holdings. In the data, firms increased their cash ratios during the last recession, and cash-intensive firms displayed higher employment growth. A tightening of firms’ credit conditions generates the same dynamics in the model. Unconstrained firms pre-emptively respond to credit supply shocks; this ...

The geography of wealth: shocks, mobility, and precautionary savings
The spatial distribution of wealth in the United States is very heterogeneous. We study the spatial distribution of wealth in a country and how it is shaped by regional earning characteristics and mobility frictions. 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 theory extends a workhorse macroeconomic model of consumption and savings under uncertainty to an economy with multiple labor markets and costly mobility. Despite complex spatial and ...

Why Do Households Save and Work?
This paper quantifies why households save and work using a life-cycle model that incorporates wage risk, endogenous labor supply of both spouses, marital transitions, health, medical expenses, mortality and bequest motives at the death of the first and last household member. We estimate it using PSID and HRS data and conduct counterfactuals to assess the quantitative role of individual mechanisms. Precautionary saving against wage risk is smaller than in models that abstract from labor supply and within-household insurance. Bequest motives and medical expenses remain important drivers of ...

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 ...
