Several studies incorporating estimated volatilities into option pricing formulas have appeared in the literature. However, the models described in these studies tend to perform quite poorly in out-of-sample tests. In particular, significant departures from the observed prices can be seen for...

This article analyzes the specifications of option pricing models based on time-changed Levy processes. We classify option pricing models based on (i) the structure of the jump component in the underlying return process, (ii) the source of stochastic volatility, and (iii) the specification of...

The fact that the expected payoffs on assets and call options are infinite under most log-stable distributions led Paul Samuelson and Robert Merton to conjecture that assets and derivatives could not be reasonably priced under these distributions, despite their many other attractive features....

It is well known that the distributions of assets returns have heavier tails than the Gaussian's. To capture such a distributional characteristic, the Generalized Hyperbolic(GH) distribution and its subclasses have been applied to assets returns as the distribution with heavier tails. GH...

In continuous time specifications, the prices of interest rate derivative securities depend crucially on the mean reversion parameter of the associated interest rate diffusion equation. This parameter is well known to be subject to estimation bias when standard methods like maximum likelihood...

This paper examines the relationship between input sector liberalization and product quality innovation and export orientation by a LDC firm given the complementarity between high input quality and high product quality. We show that input sector liberalization per se may not induce quality...

This paper uses household-level data of cellular usage to provide estimates of the implied switching costs that preclude consumers from switching providers in the face of competing offers. Our estimation differs from previous switching costs studies in that we are able to observe individual...

This paper reports a laboratory experiment to study pricing and advertising behavior in a market with costly buyer search. Sellers simultaneously post prices and decide whether or not to incur an exogenous cost to advertise their price. Sellers are not capacity constrained, and each buyer...

This paper shows how competing firms can facilitate tacit collusion by making passive investments in rivals. When firms are identical, only multilateral partial cross ownership (PCO) facilitates tacit collusion; the incentives of firms to collude in this case depend in a comlex way on the whole...

This paper analyzes a mechanism through which product market competition affects allocation of the managerial efforts. There are two types of firms, incumbents and entrants. Each incumbent firm delegates its control to a manager and cannot observe the manager's effort. The managers of incumbent...
