Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

This paper tests the prediction of the Permanent Income Hypothesis (PIH) that news about future income induce a revision in consumption equal to the revision in permanent income. We use time-series data from 48 contiguous US states to perform the test. The empirical results provide some support...

We show how tax kinks can be used to estimate the marginal propensity to consume (MPC). Tax kinks create discrete changes in the relationship between taxable income and disposable income, which - under a set of testable assumptions - enables causal identification of the spending response to...

This paper aims to fill the gaps in the analysis of risk‐sharing channels at the microlevel, both within and across households. Using data from the Bank of Italy's Survey on Household Income and Wealth covering the financial crisis, we are able to quantify in a unified and consistent framework...

Using detailed micro data, we document that households often use "stimulus" checks to pay down debt, especially those with low net wealth-to-income ratios. To rationalize these patterns, we introduce a borrowing price schedule into an otherwise standard incomplete markets model. Because interest...

This paper proposes a model of economy with weakly non-separable preferences for both work effort and consumption. Households who derive utility from consumption of a single commodity and leisure take into account the habitual dependency of their utility on both labour supply and consumption in...

We study whether households can distinguish persistent from transitory income shocks, and the implications for consumption-saving behavior. We construct a novel consumption-saving model where the household must infer the persistent component of its income process from actual income realizations...

Life expectancy for Blacks is about 8 year shorter than for Whites. A shorter life expectancy, in line with the theoretical prediction of a simple model, determines a much lower amount of savings and wealth accumulation and therefore a lower degree of insurance. This, in turn, contributes to...
