Abstract
We consider the optimal asset allocation choice of an investor who can invest in
cash (a money market bank account), nominal bonds, and stocks (the stock index).
The investor faces an incomplete market setting and is not able to perfectly hedge
long run real interest rate risk using the available securities. The optimal invest-
ment strategy is consistent with the following features of popular investment advice
which have been pointed out as puzzles: (i) a decreasing fraction of stocks in the
portfolio as time passes towards the investment horizon, and (ii) a higher bond to
stock ratio for more conservative (less risk tolerant) investors (Canner, Mankiw and
Weil, 1997). The model for asset price dynamics is calibrated to US market data
and, furthermore, risk aversion parameters and time horizons are calibrated so as
to obtain a match between the optimal asset allocations and observed investment
recommendations for \aggressive," \moderate," and \conservative" investor groups
with di®erent investment horizons.
