We address the role of imported intermediates in productivity by applying a methodology that proposes an equivalence between input–output analysis and data envelopment analysis, and decomposes sectoral productivity gains into two factors: efficiency change and technical change. We illustrate this by using data for Spain in the 2008–2015 period with three levels of labor skills, capital, and twenty-eight industries, and compare the results of two different settings: one including only domestic intermediates and the other incorporating total (i.e. both domestic and imported) inputs. We find differential results regarding productivity, efficiency, and technical changes that are attributable to imported intermediates. We also find that the main drivers of productivity change are high-skilled labor and the manufacturing sector. Our results suggest the importance of both trade and educational policies that respectively foster international economic complementarities and promote higher qualification of labor.

In parallel with the increasing availability of multiregional input–output (MRIO) tables, there has been a growing concern on IO modelling at lower levels of spatial disaggregation, to reflect the particular features of cities better. The urbanization process is one of the salient characteristics of the current stage of globalization, so it is imperative to know more about their global economic, social and environmental impacts. MRIO initiatives are defined at the country level, which means that we are potentially losing some key information about cities and their economic structures. In this paper, we fill this gap by putting together the IOT for the city of Bogota (Colombia) into the well-known OECD's ICIO database. After describing the structure of both IOTs, we document the harmonization and nesting procedures in a step by step approach, focusing on the main challenges and assumptions that we have to make. Additionally, a case study has been carried out to weight the level of integration of Bogota in global value chains. The analysis proves the low level of global integration: the bulk of the valued-added generated in Bogota due to the city's exports comes from the economy of the rest of the country and presents a significant deficit in its value-added balance. Apart, we hope it could shed some light to conduct similar adaptations for other cities. [ABSTRACT FROM AUTHOR] more...
