This paper studies the form of certain expected delay costs as a function of the arrival rate for customers who pass through a service facility that allows for reneging and retrials. We show that, under certain light traffic conditions, these costs are continuously increasing and convex...

We propose a model where wholesale electricity prices are explained by two state variables: demand and capacity. We derive analytical expressions to price forward contracts and to calculate the forward premium. We apply our model to the PJM, England and Wales, and Nord Pool markets. Our...

In this article we price a multiple-interruptible contract for the electricity market in England and Wales under a mean-reverting jump-diffusion model with seasonality. We do so by combining forward contracts with a swing option which can be exercised a pre-specified number of times. We price...

In the last 20 years, social capital, has been evoked in several field of social science research and used to explain a vast range of phenomena: political participation, institution performance, corruption, economic success of countries and so on. Unfortunately, dealing with social capital at a...

Developed countries increasingly rely on gas storage for security of supply. Widespread deregulation has created markets that help assign an objective value to existing and new to build storages. Storage valuation is nevertheless a challenging task if we consider both the financial and physical...

An omitted variable in the household's preferences specification may lead to overestimate the volatility of consumption, or alternatively to overvalue the risk aversion coefficient required to match the equity premium. This paper proposes to augment the utility function by adding a nontradable...

The understanding of joint asset return distributions is an important ingredient for managing risks of portfolios. While this is a well-discussed issue in fixed income and equity markets, it is a challenge for energy commodities. In this paper we are concerned with describing the joint return...

The purpose of this paper is to improve and discuss the asymptotic formula of the implied volatility (when maturity goes to infinity) given in [3]. Indeed, we are here able to provide more accurate at-the-money asymptotics. Such analytic formulas are useful for calibration.

We use the new procedure developed by Easley et al. to estimate the Probability of Informed Trading (PIN), based on the volume imbalance: Volume-Synchronized Probability of Informed Trading (VPIN). Unlike the previous method, this one does not require the use of numerical methods to estimate...
