input-output linkages

In a nutshell Turkey’s manufacturing sectors post faster growth through backward linkages in global value chains, whereas services sectors do so through forward linkages; agricultural sectors have the lowest participation.

This study examines how backward linkages (foreign value-added [FVA] exports) and domestic value-added (DVA) exports impact industry-level labor productivity and employment in Japan by estimating a static and dynamic panel model using data drawn from the World Input-Output Dataset and Socio-Economic Accounts. We find that the domestic content of trade is a key driver of productivity and employment in Japan for all industries, while backward linkages lead to declining productivity and foster labor displacement. A sectoral analysis reveals that productivity benefits most of the backward linkages and domestic value-added exports in the manufacturing industry but weakens as the backward linkages increase in the service industry. We find that the DVA exports variable promotes employment, whereas the FVA variable displaces it.

Participation in global value chains is widely understood to have positive effects on firms’ productivity. Less appreciated is the significance of input-output interlinkages between industrial sectors as sources of productivity spillovers. This column explores the magnitude of these effects for industries in Turkey.

Based on the world input-output database 2016 (WIOD), this study examines the impact of the global value chain (GVCs), via the backward and forward linkages, on labor productivity. Using a spatial econometric approach, it pays particular attention to the spillover effects in productivity across industries through input-output relations. It is shown that a stochastic shock in productivity in one sector significantly transcends and boosts productivity in other sectors through input-output dependencies. Moreover, productivity significantly declines with backward linkages within their sectors. However, productivity increases with forward linkages both within own sectors and across sectors through input-output relations. A sectoral analysis of the GVCs effects on productivity reveals that manufacturing backward linkages is negatively associated with productivity not only within own sectors but also across manufacturing sectors, whereas productivity in service sectors rises with forward linkages within and across service sectors. This study shows that ignoring the spillovers effects across sectors causes the estimates to be biased
