|October 2006||Financially Constrained Stock Returns|
with Horacio Sapriza, Lu Zhang: w12555
More financially constrained firms are riskier and earn higher expected returns than less financially constrained firms, although this effect can be subsumed by size and book-to-market. Further, because the stochastic discount factor makes capital investment more procyclical, financial constraints are more binding in economic booms. These insights arise from two dynamic models. In Model 1, firms face dividend nonnegativity constraints without any access to external funds. In Model 2, firms can retain earnings, raise debt and equity, but face collateral constraints on debt capacity. Despite their diverse structures, the two models share largely similar predictions.

|February 2006||Optimal Market Timing|
with Erica X. N. Li, Lu Zhang: w12014
We use a fully-specified neoclassical model augmented with costly external equity as a laboratory to study the relations between stock returns and equity financing decisions. Simulations show that the model can simultaneously and in many cases quantitatively reproduce: procyclical equity issuance; the negative relation between aggregate equity share and future stock market returns; long-term underperformance following equity issuance and the positive relation of its magnitude with the volume of issuance; the mean-reverting behavior in the operating performance of issuing firms; and the positive long-term stock price drift of firms distributing cash and its positive relation with book-to-market. We conclude that systematic mispricing seems unnecessary to generate the return-related evidence...
|August 2005||Futures Prices in a Production Economy with Investment Constraints|
with Leonid Kogan, Amir Yaron: w11509
We document a new stylized fact regarding the term-structure of futures volatility. We show that
the relation between the volatility of futures prices and the slope of the term structure of prices is
non-monotone and has a %u201CV-shape%u201D'. This aspect of the data cannot be generated by basic models
that emphasize storage while this fact is consistent with models that emphasize investment
constraints or, more generally, time-varying supply-elasticity. We develop an equilibrium model in
which futures prices are determined endogenously in a production economy in which investment is
both irreversible and is capacity constrained. Investment constraints affect firms' investment
decisions, which in turn determine the dynamic properties of their output and consequently imply
that the ...
