Are asset prices unduly volatile and often detached from their fundamentals? Does the bursting of financial bubbles depress the real economy? This paper addresses these issues by constructing a DSGE model with speculative bubbles. We characterize conditions under which storable goods, regardless...

I study the cross sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. In the model, technological progress is endogenously driven by R&D investment and is composed of two parts. One part is product innovation devoted to creating new...

Previous studies show that firms with low inventory growth outperform firms with high inventory growth in the cross-section of publicly traded firms. In addition, inventory investment is volatile and procyclical, and inventory-to-sales is persistent and countercyclical. We embed an inventory...

We show that heterogeneity in the composition of the labor force affects asset prices in financial markets in important ways. Theoretically, we combine a standard model of labor heterogeneity (Acemoglu, 2002) with a standard neoclassical q-theory model with labor adjustment costs. We then show...

We document that the firm level hiring rate predicts stock returns in the cross-section of US publicly traded firms even after controlling for investment, size, book-to-market and momentum as well as other known predictors of stock returns. The predictability shows up in both Fama-MacBeth cross...

We study the impact of labor market frictions on asset prices in the cross section of US publicly traded firms. On average, firms with low hiring rates have higher future stock returns than firms with high hiring rates, a difference of 5.2% per annum. Interpreting a hiring decision as analogous...

We explore the relationship between sticky wages and risk. Like operating leverage, sticky wages are a source of risk for the firm. Firms, industries, or times with especially high or rigid wages are especially risky. If wages are sticky then wage growth should negatively forecast future stock...

The ability of corporations to raise external equity finance varies with macroeconomic conditions, suggesting that the cost of equity issuance is time-varying. Using cross sectional data on U.S. publicly traded firms, we construct an empirical proxy of an aggregate shock to the cost of equity...

We develop a dynamic model with time variation in external equity financing costs and show that variation in these costs is important for the model to quantitatively capture the joint dynamics of firms' asset prices, real quantities, and financial flows in the U.S. economy. Growth firms and high...

In standard production models wage volatility is far too high and equity volatility is far too low. A simple modification - sticky wages due to infrequent resetting together with a CES production function - leads to both (i) smoother wages and (ii) higher equity volatility. Furthermore, the...
