One of the most important factors to control for the achievements of investment portfolio returns is risk. If we only think that a 100% positive return is needed to recover a portfolio loss of 50%, we can understand why. With the advent of the exponential growth of technology usage in markets,...

We develop a microstructure model whose order ow is driven by a Cox-BESQ process. We derive important analytical properties of the Cox-BESQ process in order to explicit the stock price dynamics at different time scales, provide different parameter estimators and solve the optimal execution...

This paper formulates dynamic density functions, based upon skewed-t and similar representations, to model and forecast electricity price spreads between different hours of the day. This supports an optimal day ahead storage and discharge schedule, and thereby facilitates a bidding strategy for...

In this paper, the authors present an EOQ model with substitutions between products and a dynamic inventory replenishment policy. The key assumption is that many products in the market are substitutable at different levels, and that, in most cases, a customer who discovers that a desired product...

This paper is concerned with analytical models and methods for reliability planning, optimization, and operation of telecommunication networks. The difference between classical models of reliability and models developed here is that the last ones take into account the economy is often an...

We deal with a retailer's multi-product inventory system where customers randomly seek acceptable substitutes if their initial requests are not satisfied. If the substitute is also unavailable, the sales request is lost. Besides the already complex multi-product inventory management problem...
