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...

The theory of intertemporal consumption choice makes sharp predictions about the evolution of the entire distribution of household consumption, not just about its conditional mean. In the paper, we study the empirical transition matrix of consumption using a panel drawn from the Bank of Italy...

We develop a new approach to the decomposition of income risk within a nonstationary model of intertemporal choice. The approach allows for changes in income risk over the life-cycle and with the business cycle. It requires only repeated cross-section data and can allow for mixtures of...

This paper investigates whether assuming that households possess advance information on their income shocks helps to overcome the difficulty of standard models to understand consumption insurance in the US. As our main result, we find that the quantitative relevance of advance information...

I quantify the welfare effects of replacing the US capital income tax with higher labor income taxes under international financial integration using a two-country, heterogeneous-agent incomplete markets model calibrated to represent the US and the rest of the world. Short-run and long-run factor...

We present evidence that shocks to household consumption growth are negatively skewed, persistent, countercyclical, and drive asset prices. We construct a parsimonious model where heterogeneous households have recursive preferences. A single state variable drives the conditional cross-sectional...

In this paper, we document that households' consumption expenditures crucially depend on their expected earnings - even after controlling for realized earnings, wealth and time-invariant unobserved characteristics such as permanent income and over-confidence. To explain this evidence, we develop...

Habit formation has been proposed as a possible solution for explaining the equity premium puzzle. This paper extends the class of models that support the habits explanation in order to account for heterogeneity in earnings, wealth, habits and consumption. I find that habit formation increases...

We analyze an optimal consumption and investment problem for a representative agent who may have different preferences for consumption and for terminal wealth. The utility for consumption is characterized by constant relative risk aversion so consumption is always positive. In contrast, the...
