January 2020Who Are the Hand-to-Mouth?
with Mark A. Aguiar, Mark Bils: w26643
Many households hold little wealth, especially liquid wealth. In precautionary savings models, absent preference heterogeneity, these households should display not only higher marginal propensities to consume (MPCs), but also lower average propensities to consume (APCs) and higher future consumption growth. We see from the PSID that such “hand-to-mouth” households actually display higher APCs and no faster spending growth. They also adjust spending to a greater extent through the number of categories consumed. Consistent with a role for preference heterogeneity, the panel data show that it is the propensity to be hand-to-mouth, not current assets, that predicts high APC, low consumption growth, and other spending differences for the hand-to-mouth. To identify the extent of preference heter...
Dynastic Precautionary Savings
This paper provides evidence that parents accumulate savings to insure their children against income risk. I refer to this behavior as dynastic precautionary saving and quantify its extent using matched parent-child pairs from the Panel Study of Income Dynamics and exploiting variation in income risk across age, industries and occupations. I then build a model of altruistically linked overlapping generations, in which parents and children interact strategically, that is quantitatively consistent with the empirical evidence. I argue that strategic interactions are important for generating the observed dynastic precautionary behavior and use the model to show this component of household savings is quantitatively important for wealth accumulation, intergenerational transfers and consumption i...
June 2019Markups and Inequality
with Virgiliu Midrigan: w25952
We study the aggregate and distributional impact of product market interventions and profit taxes using a model of firm dynamics, credit constraints and incomplete markets. A key ingredient of our model is that markups are endogenous so that the markup a producer charges depends on the amount of competition it faces. We show that size-dependent subsidies that remove the distortions due to markup dispersion lead to sizable welfare gains and reduce inequality, even though they increase firm concentration and long-run misallocation. In contrast, policies that reduce concentration lead to large output, TFP and welfare losses and increase inequality. A tax on profits greatly depresses the incentives to create new firms, reducing labor demand, after-tax wages and welfare.
April 2017Liquidity Constraints in the U.S. Housing Market
with Denis Gorea, Virgiliu Midrigan: w23345
We study the severity of liquidity constraints in the U.S. housing market using a life-cycle model with uninsurable idiosyncratic risks in which houses are illiquid, but agents can extract home equity by refinancing their mortgages. The model implies that four-fifths of homeowners are liquidity constrained and willing to pay an average of 13 cents to extract an additional dollar of liquidity from their home. Most homeowners value liquidity for precautionary reasons, anticipating the possibility of income declines and the need to make mortgage payments. The model reproduces well the observed response of consumption to tax rebates and mortgage relief programs and predicts large welfare gains from policies aimed at providing temporary liquidity relief to homeowners.
