We present evidence that the equity premium and the premium of value stocks over growth stocks are consistent in the 1982-96 period with a stochastic discount factor calculated as the weighted average of individual households' marginal rate of substitution with low and economically plausible values of the relative risk aversion coefficient. Since these premia are not explained with an SDF calculated as the per capita marginal rate of substitution with a low value of the RRA coefficient, the evidence supports the hypothesis of incomplete consumption insurance. We also present evidence that an SDF calculated as the per capita marginal rate of substitution is better able to explain the equity premium and does so with a lower value of the RRA coefficient, as the definition of asset holders is tightened to recognize the limited participation of households in the capital market

We present a consumption-based model that explains the procyclical variation of stock prices, the long-horizon predictability of excess stock returns, and the countercyclical variation of stock market volatility. Our model has an i.i.d. consumption growth driving process, and adds a slow-moving external habit to the standard power utility function. The latter feature produces cyclical variation in risk aversion, and hence in the prices of risky assets Our model also predicts many of the difficulties that beset the standard power utility model, including Euler equation rejections, no correlation between mean consumption growth and interest rates, very high estimates of risk aversion, and pricing errors that are larger than those of the static CAPM. Our model captures much of the history of stock prices, given only consumption data. Since our model captures the equity premium, it implies that fluctuations have important welfare costs. Unlike many habit-persistence models, our model does not necessarily produce cyclical variation in the risk free interest rate, nor does it produce an extremely skewed distribution or negative realizations of the marginal rate of substitution

This paper proposes a model of financial markets and corporate finance, with asymmetric information and no taxes, where equity issues, bank debt, and bond financing coexist in equilibrium. The relationship banking aspect of financial intermediation is emphasized: firms turn to banks as a source of investment mainly because banks are good at helping them through times of financial distress. This financial flexibility is costly since banks face costs of capital themselves (which they attempt to minimize through securitization). To avoid this intermediation cost, firms may turn to bond or equity financing, but bonds imply an inefficient liquidation cost and equity an informational dilution cost. We show that in equilibrium the riskier firms prefer bank loans, the safer ones tap the bond markets, and the ones in between prefer to issue both equity and bonds. This segmentation is broadly consistent with stylized facts.
