Abstract 1: We show that systematic risk falls sharply following firm
investment and rises after disin-
vestment. The risk dynamics we uncover are driven by real investment and
not by changes in
firm characteristics and are strongest among firms with valuable
investment opportunities,
high adjustment costs of investment and low operating leverage.
Consistent with rational
pricing, firms with poor investment opportunities, those most likely to
be overinvesting, ex-
perience an increase in average returns and systematic risk following
investment. For firms
with valuable growth opportunities the bulk of the negative investment
(asset growth)-future
returns relationship stems from differences in risk factor loadings
between high and low in-
vesting firms.
Abstract 2: We embed a structural model of credit risk inside a
consumption-based model, which allows us to price
equity and corporate debt in a single framework. Our key economic
assumptions are that the first and
second moments of earnings and consumption growth depend on the state of
the economy which switches
randomly, creating intertemporal risk, which agents prefer to resolve
quickly because they have Epstein-
Zin-Weil preferences; agents choose capital structure and default times.
Our model generates co-movement
between aggregate stock return volatility and credit spreads, consistent
with the data and potentially resolves
the equity risk premium and credit spread puzzles.
