We construct an equilibrium model of firm diversification to 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...

This Paper suggests that skill accumulation through past work experience, or ‘learning-by-doing’ (LBD), can provide an important propagation mechanism in a dynamic stochastic general equilibrium model, as the current labour supply affects future productivity. Our econometric analysis uses a...

We incorporate costly external finance in a production based asset pricing model and investigate whether financing frictions are quantitatively important for pricing a cross-section of expected returns. We show that the common assumptions about the nature of the financing frictions are captured...

A search-theoretic general equilibrium model of frictional unemployment is shown to be consistent with some of the key regularities of unemployment over the business cycle. In the model the return to a job moves stochastically. Agents can choose either to quit and search for a better job, or...

This Paper asks whether the asset pricing fluctuations induced by the presence of costly external finance are empirically plausible. To accomplish this, we incorporate costly external finance into a dynamic stochastic general equilibrium model and explore its implications for the properties of...

We explicitly link expected stock returns to firm characteristics such as firm size and book-to-market ratio in a dynamic general equilibrium production economy. Despite the fact that stock returns in the model are characterized by an intertemporal CAPM with the market portfolio as the only...

We examine optimal leverage for a downstream firm relying on implicit (self-enforcing) contracts with a supplier. Performing a leveraged recapitalization prior to bargaining increases the firm's share of total surplus. However, the resulting debt overhang limits the range of credible bonuses,...

Using a large sample of bank loans issued to U.S. firms between 1990 and 2004, we find that lower takeover defenses (as proxied by the lower G-index of Gompers, Ishii, and Metrick 2003) significantly increase the cost of loans for a firm. Firms with lowest takeover defense (democracy) pay a 25%...

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...
