A substantial part of production and trade now takes place through global value chains (GVC), making it an essential conduit of knowledge spillover and technology transfer. Yet, extant studies examining how countries become productively efficient and catch-up to the global efficiency frontier through international trade have ignored the possible role of GVC in fast-tracking this process. This paper provides the first empirical evidence that fills this knowledge gap. We propose a two-stage empirical strategy to this end. First, we use a data envelopment analysis (DEA) approach to compute a measure of productive efficiency—defined herewith as a country’s relative productive efficiency to the global productive efficiency frontier. Second, we use the productive efficiency index as an outcome variable in a reduced-form equation that controls for GVC participation and its interaction with country characteristics that influence the gains from GVC participation. In addition to using the panel fixed effect method, we estimate the reduced-form equation with the difference-GMM to address endogeneity issues, and the Tobit and Fractional Response models to address the bounded nature of the productive efficiency index. We find strong evidence suggesting that GVC participation enables technology-lagging countries to become more productively efficient as well as catch-up to the global efficiency frontier. We also find that the productive efficiency and catch-up gains from GVC participation accrue more strongly to countries that have a high human capital stock, a well-functioning financial market, maintain stable macroeconomic conditions, and specialize in downstream activities in the value chain.@en

In 1987, Robert M. Solow hinted at the computer age and productivity statistics puzzle. While this puzzle persisted for many years, a growing literature has picked it up to examine the effect of ICTs on technical efficiency. However, this literature has focused mainly on quantity-based ICTs measures, which have come under severe criticism in recent times. We advance this literature in this paper by shifting the focus of analysis to quality-based ICTs measures; in this case, Internet quality. We also extend the literature by examining how the envisaged relationship between ICTs quality and technical efficiency is conditioned by a country's unique attributes. Our results show a significantly positive effect of ICTs quality on technical efficiency. We also find that the technical efficiency gains associated with ICTs quality are higher in skill-abundant countries, countries that engage more intensively in cross-border trade, have stronger contracting institutions, and are endowed with well-functioning and well-developed financial markets that ensure greater efficiency of capital allocation. We find a network effect in the nexus between ICTs quality and technical efficiency. That is, the marginal effect of ICTs quality on technical efficiency increases as the number of Internet users expands. We discuss the policy implications of our findings.@en

Exporting higher quality and complex products is deemed pathway to economic growth and development. However, producing such products is knowledge-intensive and requires quality intermediate inputs and advanced technologies. Integration into global trade networks is increasingly argued to be among the pathways to obtain such inputs and technologies, although not all countries may benefit equally from such integration. This paper builds on these arguments and investigates how participation in the global value chain (GVC) affects the quality of exported products. Using a highly disaggregated product-level export data from 122 countries, we find that participation in (backward and forward) GVC impacts positively on the quality of exported products and brings the quality level closer to the quality frontier. While this result persists in the sub-sample comprising developed countries, developing countries only benefit from backward GVC participation. Overall, the results indicate that GVC participation matters to export upgrading but points to a potential heterogeneity on the channel of impact across countries at different levels of development.@en
