How production networks amplify economic growth

Technological improvement is the most important cause of long-term economic growth. In standard growth models, technology is treated in the aggregate, but an economy can also be viewed as a network in which producers buy goods, convert them to new goods, and sell the production to households or other producers. We develop predictions for how this network amplifies the effects of technological improvements as they propagate along chains of production, showing that longer production chains for an industry bias it toward faster price reduction and that longer production chains for a country bias it toward faster growth. These predictions are in good agreement with data from the World Input Output Database and improve with the passage of time. The results show that production chains play a major role in shaping the long-term evolution of prices, output growth, and structural change.

An Empirical Investigation of Global Production Networks in Indian Manufacturing Sector

This article attempts to dive into the operation of global production networks in India with manufacturing sector in the primary scope of focus. It aims to analyse the long-run and short-run relationship among the factors which form a global supply chain and their effects on a supply chain, using yearly data from 1984 to 2017. Our primary results from the estimations show that all the factors incorporated into the study are important for initiation and effective execution of a supply chain. The autoregressive distributed lag model shows that Index of Industrial Production (IIP), export–import ratio, KOF index and electricity index affect a supply chain positively whereas USD–INR exchange rate and unemployment rate affect gross value added negatively. The error correction model shows long-run relationship between IIP and export–import ratio. The study also highlights the importance of trade balance and industrial production in the long run.
