Ipe : A Computable Index Measuring Market Evolutionary Pressure

The working paper is concerning with the definition of IPE, a computable index measuring the intensity of the evolutionary process relative to a given market. In order to reach such a goal, by using a suitable set of axioms, it is necessary to reconstruct the evolution of the firm productive structures, as well as to measure the performance of each unit operating in the environment under examination. The second task is accomplished with the help of indices such as EVA - or "Economic Value Added" - and AV - or "Added Value"
