Carroll and Kimball (1996) show that the consumption function for an agent with time-separable, isoelastic preferences is concave in the presence of income uncertainty. In this paper I show that concavity breaks down if we abandon time-separability. Namely, if an agent maximizing an isoelastic...

On average young people "undersave" whereas old people "oversave" with respect to the rational expectations model of life-cycle consumption and savings. According to numerous studies on subjective survival beliefs, young people also "underestimate" whereas old people "overestimate" their...

We construct and solve a dynamically inconsistent Choquet expected utility life-cycle model for naive and sophisticated agents, respectively. Pollak (1968) shows that the realized saving behavior of naive and sophisticated agents be- comes identical for a logarithmic period-utility function. As...

How accurate are older people's expectations about their future Social Security benefits? Using panel data from the Health and Retirement Study, we compare respondents' observed Social Security claiming ages and benefits with subjective expectations provided during their 50s and early 60s. We...

Matched transaction-level, credit-registry, and survey-based data reveal that consumers on average form excessively high (low) income expectations relative to ex-post realizations after unexpected positive (negative) income shocks. These extrapolative income expectations lead consumers to...

The paper combines Baumol's model of structural change with a model of aggregate demand growth in the Keynesian-Kaleckian tradition to predict the dynamics of aggregate employment. The model for the demand regime is estimated with - and Baumol's model for the productivity regime is calibrated on...
