In this Paper we show that the main empirical findings about firm diversification and performance are actually consistent with the optimal behavior of a firm that maximizes shareholder value. In our model, diversification allows a firm to explore better productive opportunities while taking...

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...

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...

In this paper we first propose a proxy for the maturity of a country’s export bundle based on product life cycle theory. Employing a conditional latent class model, we then examine the effect of maturity of countries’ exports on their economic growth for 98 countries over the period 1988 to...

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...
