Export Variety and Imported Intermediate Inputs: Industry-Level Evidence from Africa

Imported intermediate inputs offer access to lower-priced, higher quality, and a wider variety of inputs that can increase the possibility of producing and selling more diversified products in foreign markets. In this paper, we examine this relationship using a novel manufacturing industry-level data across 26 African countries over the 1995-2016 period. We find strong evidence of a positive relationship between imported intermediate inputs and the variety of exported products. Further analyses in the study indicate that imported intermediate inputs positively affect the variety of exported products because they offer lower-priced, and higher-quality/technology embodied inputs. However, the positive effect of imported intermediate inputs on the variety of exported products depend on industry's absorptive capacity, especially when the inputs are sourced from advanced countries. We discuss the implications of our findings.

Emmanuel was among the first cohort of fellows at IMANI who pioneered the assessment of the feasibility of political party manifestos in Ghana. Owing to this work, keen interest in critical evaluation of party manifestos has taken root and become an integral part of Ghana's political cycle. His research focuses on development economics, in particular, the economics and measurement of structural change.
