Environment and economic efficiency: an analysis of some polluting Italian industries
No full textWP 03/2011; this research presents an extension of the directional distance function model to measure performances for firms which produce a large number of pollutants and operate in different industrial sectors. I use this methodology to estimate productivity indexes on a sample of Italian firms that were forced to declare their emissions to the European Pollution Release and Transfer Register in 2007. A proxy for the environmental regulation’s cost is derived and results show a significant impact in term of potential value added lost. Estimations also reveal differences in mean environmental performances among industries; furthermore, the effect of pollution control follows the same path

An artificial neural network approach for assigning rating judgements to Italian Small Firms
No full textWP 04/2011; Based on new regulations of Basel II Accord in 2004, banks and financial nstitutions have now the possibility to develop internal rating systems with the aim of correctly udging financial health status of firms. This study analyses the situation of Italian small firms that are difficult to judge because their economic and financial data are often not available. The intend of this work is to propose a simulation framework to give a rating judgements to firms presenting poor financial information. The model assigns a rating judgement that is a simulated counterpart of that done by Bureau van Dijk-K Finance (BvD). Assigning rating score to small firms with problem of poor availability of financial data is really problematic. Nevertheless, in Italy the majority of firms are small and there is not a law that requires to firms to deposit balance-sheet in a detailed form. For this reason the model proposed in this work is a three-layer framework that allows us to assign ating judgements to small enterprises using simple balance-sheet data
