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

While household well-being derives from long-term average rates of consumption, welfare comparisons typically rely on shorter-duration survey measurements. We develop a new strategy to identify the distribution of these long-term rates by leveraging a large-scale randomization in Iraq that...

In this paper, we develop and numerically solve a model of idiosyncratic labour income and idiosyncratic interest rates to predict the evolution of a wealth distribution over time. Stochastic labour income follows a deterministic growth trend and it fluctuates between a wage and unemployment...

This paper quantifies the extent of heterogeneity in consumption responses to changes in real interest rates and house prices in the four largest economies in the euro area: France, Germany, Italy, and Spain. We first calibrate a life-cycle incomplete-markets model with a financial asset and...

The lifecycle approach is the workhorse to model saving decisions of individuals. It conjectures individuals preferring a constant consumption stream across their lifecycle saving till retirement and dis-saving thereafter. The reality is often at odd with this assumption giving rise to our...

We document a decline in the frequency of shopping trips in the U.S. since 1980 and consider its implications for the measurement of consumption inequality. A decline in shopping frequency as households stock up on storable goods (i.e. inventory behavior) will lead to a rise in expenditure...

Occupational specificity of human capital motivates an important role of occupational reallocation for the economy's response to shocks and for the dynamics of inequality. We introduce occupational mobility, through a random choice model with dynamic value function optimization, into a...

In this paper, we document that households consumption expenditures depend on their expected earnings even after controlling for realized earnings and wealth. To explain this evidence, we develop and structurally estimate a standard-incomplete markets model in which rational households possess...

In this paper, we define "The Chinese Saving Puzzle" as the persistently high national saving rate at 34-53 percent of gross domestic product (GDP) in the past three decades and a surge in the saving rate by 11 percentage points from 2000-2008. Using data from the Flow of Funds Accounts (FFA)...

China's household saving rate has increased markedly since the mid-1990s and the age-saving profile has become U-shaped. Using a panel of urban Chinese households covering 1989-2006, we document a sharp increase in income uncertainty. While the permanent variance of household income was stable,...
