Abstract: L'obiettivo principale di questo studio e' comparare coefficienti tecnici calcolati a prezzi correnti e a prezzi deflazionati secondo tre differenti metodologie (deflatore singolo, deflatori settoriali e deflatori specifici), allo scopo di identificare l'impatto che queste strategie di calcolo alternative possono avere per l'analisi del cambio strutturale. Il confronto e' effettuato per il Brasile e il Messico, sulla base delle World Input-Output Tables (WIOT) riferite agli anni tra il 2000 e il 2014. L'ipotesi centrale e' che, a seconda del metodo di deflazione utilizzato, i settori che presentano una variazione significativa dei prezzi relativi possono subire una variazione dei coefficienti tecnici senza che cio' sia dovuto ad una variazione nelle quantita' di input. La conclusione piu' importante e' che i risultati osservati per le due economie non sono indifferenti al metodo di deflazione utilizzato, con implicazioni per l'analisi dei cambiamenti strutturali. This paper aims to compare the technical coefficients at current and deflated prices according to three deflation methods (single deflator, sectoral deflators, and specific deflators) and identify how it impacts the analysis of the structural changes. The comparison is made for Brazil and Mexico based on the World Input-Output Tables (WIOT) between 2000 and 2014. The central hypothesis is that, depending on the deflation method used, sectors that have a significant variation in relative prices may have their technical coefficients increased/decreased without this being related to the inputs needed to produce an additional unit of product. The most important conclusion is that the results observed for the two economies are not indifferent to the deflation method used, having implications for the analysis of structural changes.
