Does policy uncertainty affect productivity? Policy uncertainty creates delays as firms await new information about prices, costs and other market conditions before committing resources. Such delays can have real consequences on firms’ productivity and corporate decisions. First, we find that...

The log-normal Garman and Kohlhagen (1983) currency option model usually creates pricing biases when matched with the market prices. The observed price bias pattern is generally consistent with the mixed jump-diffusion distribution for exchange rates. Various studies have provided evidence of...

This paper uses an extension of the equilibrium model of Lucas (1978) to study the valuation of options on the market portfolio with return predictability, endogenous stochastic volatility and interest rates. Equilibrium conditions imply that the mean-reverting of the rate of dividend growth...

Bank loans are more available and cheaper for new and small businesses in the US in areas with highly concentrated banks than in areas with highly competitive banks. We explain this fact by analyzing banks' decisions to screen risky projects and their subsequent competition in loan provisions....

We explain why underpricing in IPOs can be large in magnitude and clustered, using a signalling model where firms have private information about their qualities (high or low). A novel feature is that a firm, if perceived by the market as high quality, benefits from the industry's publicity which...

This study analyzes the valuation of housing index derivatives traded on the Chicago Mercantile Exchange (CME). Specifically, to circumvent the nontradability of housing indices, we propose and implement an equilibrium valuation framework. Assuming a mean‐reverting aggregate dividend process...
