Heterogeneous life-cycle profiles, income risk and consumption inequality

Primiceri, Giorgio E.; Rens, Thijs van - Department of Economics and Business, Universitat … - 2006

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...

A simple model of multiple equilibria based on risk

Costain, James S. - Department of Economics and Business, Universitat … - 1998

This paper shows how risk may aggravate fluctuations in economies with imperfect insurance and multiple assets. A two period job matching model is studied, in which risk averse agents act both as workers and as entrepreneurs. They choose between two types of investment: one type is riskless,...

The risk of divorce and household saving behavior

Luna, Libertad González; Özcan, Berkay - Department of Economics and Business, Universitat … - 2008

We analyze the impact of an increase in the risk of divorce on the saving behaviour of married couples. From a theoretical perspective, the expected sign of the effect is ambiguous. We take advantage of the legalization of divorce in Ireland in 1996 as an exogenous increase in the likelihood of...

Inequality over the business cycle: Estimating income risk using micro-data on consumption

Primiceri, Giorgio; Rens, Thijs van - Department of Economics and Business, Universitat … - 2002

We use CEX repeated cross-section data on consumption and income, to evaluate the nature of increased income inequality in the 1980s and 90s. We decompose unexpected changes in family income into transitory and permanent, and idiosyncratic and aggregate components, and estimate the contribution...

Credit card debt puzzles

Haliassos, Michael; Reiter, Michael - Department of Economics and Business, Universitat … - 2005

Most US credit card holders revolve high-interest debt, often combined with substantial (i) asset accumulation by retirement, and (ii) low-rate liquid assets. Hyperbolic discounting can resolve only the former puzzle (Laibson et al., 2003). Bertaut and Haliassos (2002) proposed an...
