Previous empirical literature has found a sharp decline in consumption during the first years of retirement implying that individuals do not save enough for their retirement. This phenomenon has been called the retirement consumption puzzle. In contrast to some of the previous studies, the...

This paper concerns the decomposition of income risk into permanent and transitory components using repeated cross-section data on income and consumption. Our focus is on the detection of changes in the magnitudes of variances of permanent and transitory risks. A new approximation to the optimal...

We develop a new approach to the decomposition of income risk within a nonstationary model of intertemporal choice. The approach allows for changes in income risk over the life-cycle and with the business cycle. It requires only repeated cross-section data and can allow for mixtures of...
