Many exotic derivatives do not have closed-form valuation equations, and must be priced using approximation methods. Where they can be applied, standard lattice techniques based on binomial and trinomial trees will achieve correct valuations asymptotically. They can also generally handle...

The paper investigates how the availability heuristic of individual stocks affects equity returns, where the availability heuristic is measured by the irrational signal in the fractal dimension. Our evidence support that the availability heuristic can positively predict the short-term expected...

In this paper, we propose an alternative approach for pricing and hedging Americanbarrier options. Specifically, we obtain an analytic representation for the value and hedge parameters of barrier options, using the decomposition technique of separating the European option value from the early...

This paper provides an analytical solution to the problem of how an institution might optimally manage the market risk of a given exposure, under the assumption that the institution wishes to minimize its Value at Risk (VaR) using options. The solution specifies the VaR-minimizing level of...

This paper addresses the question of how an institution might optimally manage the market risk of a given exposure. We provide an analytical approach to optimal risk management under the assumption that the institution wishes to minimize its Value-at-Risk (VaR) using options follows a geometric...

This paper explores why the size effect vanished after the early 1980s. We show that the size effects are significantly positive primarily at the bottom of the business cycles. More importantly, this dependency of the size effect on the business cycles is preserved even after the 1980s....

We posit the time cost required for managing risky asset investment including conducting research and monitoring its performance. An economic agent, who should allocate a limited amount of time to labor, leisure and risky investment, is subject to the opportunity time cost, which is forgone...
