Within the context of the Permanent Income Hypothesis (PIH), the predictions for consumption depend crucially upon the process for income. In this paper, we consider an unobserved components model that allows for both asymmetric transitory movements and correlation between permanent and...

This paper studies the consumption decisions of agents who face costs of acquiring, absorbing and processing information. These consumers rationally choose to only sporadically update their information and re-compute their optimal consumption plans. In between updating dates, they remain...

I incorporate expectations-based reference-dependent preferences into a dynamic stochastic model to explain three major life-cycle consumption facts; the intuitions behind these three implications constitute novel connections between recent advances in behavioral economics and prominent ideas in...

This paper observes the Turkish household’ consumption data to see whether it follows random walk or not. The quarterly data covers the period from 1987:1 to 2003:4. By employing the direct tests for random walk, excess smoothness or excess sensitivity, this study results in both excess...

State-level consumption exhibits excess sensitivity to lagged income to the same extent as US aggregate data, but state-specific (idiosyncratic) consumption exhibits substantially less sensitivity to lagged stste-specific income - a result that also holds for Canadian provinces. We propose the...

This paper finds that a benchmark model of habit formation in consumer preferences can explain two well-known failures of the permanent income hypothesis: the sensitivity of aggregate consumption to predictable changes in income and to lagged consumer sentiment. One novel feature of the paper's...

This paper explores whether habit formation in the representative agent’s preferences can explain two failures of the standard permanent income model: the sensitivity to lagged consumer sentiment, and to predictable changes in income. I show that in a habit formation model, the sensitivity of...

We test for precautionary saving and excess sensitivity of consumption to predicted income growth using a 1989-93 panel survey of Italian households that has measures of subjective income and inflation expectations. These expectations provide a powerful instrument for predicting income growth....

In this paper I estimate the age-wealth profile under two different identification assumptions about age, cohort and time effects. According to the life-cycle model, the two set of assumptions should yield similar age-wealth profiles. Using the 1984-1993 Italian Survey of Household Income and...

As is generally acknowledged, the failure of the perfect credit markets assumption underlying the permanent income hypothesis may be responsible for low consumption smoothing and observed excess sensitivity of consumption to current income. The economic literature puts forward a number of...
