A Jump-Diffusion Model of Shipping Freight Rate

To draw a model that can describe shipping freight rate fluctuation precisely has never been so important since the ship investment evaluated under the framework of real options. We set a general double exponential jump-diffusion model, which generates a leptokurtic distribution. Compared with geometric Brownian motion model, the general double exponential jump diffusion model is more appropriately in matching the key features of shipping freight rate returns.
