An intertemporal linear price model with extractions

The problem of lack of competitiveness has become one of the main concerns of European governments. This is reflected trough out the Europe 2020 Strategy that includes as key priority the promotion and efficient and productive use of inputs. Differently to other ?well-behaved? European ?neighbours?, in Spain productivity growth closely connected to competiveness improvements has been remarkably slow during the last decade. Some analysts consider that the bad evolution of Spanish competiveness levels is basically due to the increase in labour costs during these years. Consequently, this paper pursues to shed some light on the possible main reasons that explains the lack of competiveness in the Spanish economy. In doing so, we use a multi-sectoral approach employing yearly Input-Output data for this economy that covers the 2000-2007 time-frame. This is the empirical contribution of our paper. In terms of methodology, to the best of our knowledge, the contribution of this paper relating to the Hypothetical Extraction Method (HEM) is two-fold. Differently to what is common practise, the first contribution has to do with evaluating endogenous price impacts using the HEM. Expanding the application of the original approach first proposed by Leontief (1949), the second contribution consists in introducing an inter-temporal analysis within the HEM. This helps in the analysis of the evolution and the main determinants of the rise in price levels that has generated a decline in Spanish competitiveness levels.
