This paper presents a flexible new family of copula-based multivariate models designed for handling large numbers of variables (1) as random vectors in the static case or (2) as vector stochastic processes in the dynamic case. The family includes models with upper and lower tail dependence....

By analogy with Social Licence to Operate, Social Licence to Finance refers to the pressure put by society as a whole on the finance industry not to fund projects that are considered as socially undesirable/irresponsible. Because of coal's contribution to greenhouse gas emissions and hence to...

Securing stable long-term supplies of raw materials is vital for industrialized nations. China, Japan and South Korea are three countries in East Asia which import large quantities of raw material, especially metals and petroleum products. Unlike the other two, China has large mines and...

The standard approach of evaluating flexible power plants in deregulated markets is by modelling the spark spread. While this takes account of the volatility of electricity prices and cost of gas and CO2, it does not take account of technical costs (such as ramping up and down) and it ignores...

This article analyses long-term dynamic hedging strategies relying on term structure models of commodity prices and proposes a new way to calibrate the models which takes into account the errors associated to the hedge ratios. Different strategies, with maturities up to seven years, are tested...

The main result of this article is the presentation of the Distribution Match Method. This method applies to a general multi-factor pricing model under assumption of normal law drift. The idea is to find an equivalent one-factor model for European options. The equivalent model admits a weak...

The mathematical method called Plurigaussian Simulations was invented in France in the 1990s for simulating the internal architecture of oil reservoirs. It rapidly proved useful in other domains in the earth sciences: mining, hydrology and history matching. This paper tracks its diffusion...

The importance of being able to identify changepoints in financial time series has been stressed by many authors, both for econometric forecasting and for enhancing the performance of trading strategies. Strategies which work well in one type of context may lose money under different...
