Abstract

We estimate a nominal life-cycle portfolio choice model using shopping costs
to generate money demand. The model delivers realistic implications for
stock market participation and portfolio composition because money crowds
out other assets at lower levels of wealth. We quantify how changing
correlations between inflation, real bond and stock returns, and changes in
the inflation process affect household portfolios. Higher mean inflation
increases stock market participation, while portfolios shift to bonds and
stocks, and away from money. A negative inflation-bond return correlation,
or a positive stock-bond return correlation, reduces the diversification
benefit from holding bonds, encouraging a higher stock exposure.

Keywords: Life cycle models, portfolio choice, Infl‡ation, money demand, stock market participation, uninsurable labor income risk
