It is common to recognize that ideas, technology and information disseminate across the economy following some kind of diffusion pattern. Typically, the process of adopting a new piece of knowledge will be translated into an s-shaped trajectory for the adoption rate. This type of process of...

This discussion paper resulted in a publication in the <I>European Journal of Operations Research</I> (2010), pages 1380-1397.<P> There are various importance sampling schemes to estimate rare event probabilities in Markovian systems such as Markovian reliability models and Jackson networks. In this work,...</p></i>

In: <I>Proceedings Winter Simulation Conference</I>, 9-12 December 2012, pages 387-398.<P> In rare event simulation, we look for estimators such that the relative accuracy of the output is ''controlled'' when the rarity is getting more and more critical. Different robustness properties have been defined...</p></i>

In today’s world, transport management is a key strategic factor for the achievement of organizational goals such as economic efficiency and effectiveness. Likewise, transport decisions are important for the development and establishment of organizational policies aiming at enhancing...

Markov processes are used in a wide range of disciplines, including finance. The transition densities of these processes are often unknown. However, the conditional characteristic functions are more likely to be available, especially for Lévy-driven processes. We propose an empirical likelihood...

The capital market is a reflexive dynamical input/output construct whose output (time series) is usually assessed by an index of roughness known as Hurst’s exponent (H). Oddly enough, H has no theoretical foundation, but recently it has been found experimentally to vary from persistence (H ...

This paper examines the strategy in resource allocation of a firm which must choose between several production functions. These latter ones can differ by their respective initial investment amounts, input costs, output levels and prices...Such management problem is often posed when input values...

This Technical Document describes the foundations for an aggregation matrix function implemented in MATLAB, including the format and structure of the required aggregation vector used as an argument to the function. The function is passed with the N-dimensional aggregation vector as an argument....

This document describes the process used to create usable tables from the 27 individual GAMS files in .DAT format generated by IMPLAN software. 26 of these are social accounting matrix (SAM) data files and 1 is an employment-by-industry data file. By performing the appropriate command in MATLAB,...

This TechDoc describes the steps necessary to apply the Structural Decomposition Analysis (SDA) using Matlab. The code has two stages. The first stage, which comprises PrepSDA.m and RAS_SDA.m, prepares the data and the input required for SDA based on the accounting identities defined in Miller...
