Africa in Manufacturing Global Value Chains: Cross-Country Patterns in the Dynamics of Linkages
(World Bank, Washington, DC, 2020-10)Africa's linkages in manufacturing global value chains are reasonably high compared with other developing regions. Still, linkage rates have declined steeply in recent years in non-resource rich countries in the region although they have increased sharply in countries that are rich in natural resources. Moreover, the level and dynamics of linkages to manufacturing global value chains vary significantly between countries within each group of natural resource endowments. The current levels, activity structure, and geographic configuration of linkage rates evolved over the past 20 years. In addition, these linkages cut across broad activity categories, including manufacturing textiles and apparel, metal products, transport equipment, and electrical goods. This paper analyzes the sources of the variation in linkage rates in the framework of an estimated gravity and linear probability model. It is shown that the domestic actors in these linkages are typically relatively large establishments (100 or more employees) and have been in operation for five years or longer. These manufacturers are also more likely to have foreign equity holders or foreign technology licenses. These findings should be seen in the light of policies that promote industrialization by facilitating integration into manufacturing global value chains at links that maximize job and productivity gains. -

Market Size, Sunk Costs of Entry, and Transport Costs: An Empirical Evaluation of the Impact of Demand-Side Factors versus Supply-Side Factors on Manufacturing Productivity
(World Bank, Washington, DC, 2019-06)This paper uses plant-level, panel data from the Ethiopian manufacturing census to estimate the effects of demand-side and supply-side factors on industrywide aggregate productivity. The paper focuses on the effects of three factors: (1) local market size, (2) the value of transportation costs that firms incur in selling to customers outside their market, and (3) licensing fees needed to enter the market. Identification is based on a model of production under monopolistic competition, which enables interpreting the estimated coefficients of a reduced form, dynamic productivity equation. The paper analyzes 11 industries in Ethiopia over 2000 to 2010. Several interesting results emerge. In the most parsimonious specification, the estimated coefficients are consistent with all three predictions of the model—but only for one industry: cinder blocks. In this industry, the expansion of the local market boosts industrywide total factor revenue productivity, while increases in transport costs and licensing fees reduce it. The picture is somewhat mixed in the other 10 industries but broadly consistent with the predictions of the model.
