This paper examines the pricing of options by approximating extensions of the Black-Scholes setup in which volatility follows a separate diffusion process. It gereralizes the well-known binomial model, constructing a discrete two-dimensional lattice. We discuss convergence issues extensively and...

This paper constructs a model for the evolution of a risky security that is consistent with a set of observed call option prices. It explicitly treats the fact that only a discrete data set can be observed in practice. The framework is general and allows for state dependent volatility and jumps....

Viewing binomial models as a discrete approximation of the respective continuous models, the interest focuses on the notions of convergence and especially "fast" convergence of prices. Though many authors were proposing new models, none of them could successfully explain better performance for...

This paper uses an asymptotically valid expansion to derive explicitly agent's individual demand schedules and then the equilibrium allocations in options. Agents derive financial and non-tradeable income over time; they can only partially offset the latter using bonds and stocks and the option...

To improve the detection of the economic ”danger zones” from which severe banking crises emanate, this paper introduces classification tree ensembles to the banking crisis forecasting literature. I show that their out-of-sample performance in forecasting binary banking crisis indicators...

This paper studies the effects of non-contractability of investment on the choices made by a health authority and the hospital with which it contracts for the provision of a specific service. We deal with a situation where the parties must write a short-term contract, that is, where they are...
