Lower returns to maturity transformation in the face of flatter yield curves and an inability to offer deposit rates significantly...

This paper examines vertical integration incentives in the presence of a cost-reducing technology. Combining the technology adoption and vertical merger literatures in a simple duopoly model, I show that asymmetric integration can occur even in a purely symmetric set-up, without synergies or...

We study the effect of corporate board structure on firm performance under different product market conditions. Using customer-supplier links to identify exogenous downstream demand shocks, we find that board independence has a more significant effect on firm performance when the firm-specific...
