Using data from the Consumer Expenditure Survey we first document that the recent increase in income inequality in the US has not been accompanied by a corresponding rise in consumption inequality. Much of this divergence is due to different trends in within-group inequality, which has increased...

This Paper first documents the evolution of the cross-sectional income and consumption distribution in the US in the past 25 years. Using data from the Consumer Expenditure Survey we find that a rising income inequality has not been accompanied by a corresponding rise in consumption inequality....

This Paper explores the implications of the recent sharp rise in US wage inequality for welfare and the cross-sectional distributions of hours worked, consumption and earnings. From 1967 to 1996 cross-sectional dispersion of earnings increased more than wage dispersion, due to a rise in the...

Using an OLG model with heterogeneous households, we investigate the relationship among income risk, macroeconomic and demographic changes, and economic inequality between 1980 and 2000 in Japan. By decomposing the primary factors in earnings and consumption inequality into macroeconomic...

This paper discusses the links between earnings, consumption and economic welfare inequality. It places emphasis on the role of leisure and labor supply in the assessment of cross-household inequality and argues that the documented increase of such inequality has its origin in the labor market....

In this paper, we incorporate a price search decision into an incomplete markets model and differentiate consumption from expenditure. In our model, consumers are allowed to allocate part of their time on searching for low prices which leads to an endogenous price dispersion. A plausibly...

In this paper, we incorporate a price search decision into a life cycle model and differentiate consumption from expenditure. Consumers with low wealth and bad income shocks search more for cheaper prices and pay less, which makes their consumption higher than in a model without search option. A...

In an economy with a seniority wage system, elderly workers are subject to greater income risks when they lose their jobs than young workers are. This paper investigates: (1) whether we can observe the age dependence of idiosyncratic income risks; and (2) the importance of age dependecne for the...

The rise in consumption inequality in response to the increase in income inequality over the last three decades in the U.S. is puzzling to expected-utility-based incomplete market models. The two-sided lack of commitment models exhibit too little consumption inequality while the standard...

The rise in within-group consumption inequality in response to the increase in within-group income inequality over the last three decades in the U.S. is puzzling to expected-utility-based incomplete market models. The two-sided lack of commitment models exhibit too little consumption inequality...
