Optimal Diversification: Reconciling Theory and Evidence
Published: 03/25/2004 | DOI: 10.1111/j.1540-6261.2004.00641.x
Joao Gomes, Dmitry Livdan
In this paper we show that the main empirical findings about firm diversification and performance are consistent with the maximization of shareholder value. In our model, diversification allows a firm to explore better productive opportunities while taking advantage of synergies. By explicitly linking the diversification strategies of the firm to differences in size and productivity, our model provides a natural laboratory to investigate several aspects of the relationship between diversification and performance. Specifically, we show that our model can rationalize the evidence on the diversification discount (Lang and Stulz (1994)) and the documented relation between diversification and productivity (Schoar (2002)).
Equilibrium Asset Pricing with Leverage and Default
Published: 11/09/2020 | DOI: 10.1111/jofi.12987
JOÃO F. GOMES, LUKAS SCHMID
We develop a general equilibrium model linking the pricing of stocks and corporate bonds to endogenous movements in corporate leverage and aggregate volatility. The model features heterogeneous firms making optimal investment and financing decisions and connects fluctuations in macroeconomic quantities and asset prices to movements in the cross section of firms. Empirically plausible movements in leverage produce realistic asset return dynamics. Countercyclical leverage drives predictable variation in risk premia, and debt‐financed growth generates a high value premium. Endogenous default produces countercyclical aggregate volatility and credit spread movements that are propagated to the real economy through their effects on investment and output.
Levered Returns
Published: 03/19/2010 | DOI: 10.1111/j.1540-6261.2009.01541.x
JOAO F. GOMES, LUKAS SCHMID
This paper revisits the theoretical relation between financial leverage and stock returns in a dynamic world where both corporate investment and financing decisions are endogenous. We find that the link between leverage and stock returns is more complex than static textbook examples suggest, and depends on the investment opportunities available to the firm. In the presence of financial market imperfections, leverage and investment are generally correlated so that highly levered firms are also mature firms with relatively more (safe) book assets and fewer (risky) growth opportunities. A quantitative version of our model matches several stylized facts about leverage and returns.
