Using the Korean manufacturing firm-level data, this paper confirms that three stylized facts on importing hold in Korea: the ratio of imported inputs in total inputs tends to be procyclical; the use of imported inputs increases productivity; and larger firms are more likely to use imported inputs. As a result, we find that firm-level import decisions explain a non-trivial fraction of aggregate productivity fluctuations in Korea over the period between 2006 and 2012. Main findings of this paper suggest a possible link between the recent global productivity slowdown and the global trade slowdown.
This paper presents empirical evidence on the impact of competition on firm productivity. Using firm-level observations from the World Bank Enterprise Survey database, we find a positive and robust causal relationship between our proxies for competition and our measures of productivity. We also find that countries that implemented product-market reforms had a more pronounced increase in competition, and correspondingly, in productivity: the contribution to productivity growth due to competition spurred by product-market reforms is around 12-15 percent.
This volume uses the study of firm dynamics to investigate the factors preventing faster productivity growth in Latin America and the Caribbean, pushing past the limits of traditional macroeconomic analyses. Each chapter is dedicated to an examination of a different factor affecting firm productivity - innovation, ICT usage, on-the-job-training, firm age, access to credit, and international linkages - highlighting the differences in firm characteristics, behaviors, and strategies. By showcasing this remarkable heterogeneity, this collection challenges regional policymakers to look beyond one-size-fits-all solutions and create balanced policy mixes tailored to distinct firm needs.

This paper examines the response of industries and firms to changes in trade costs. Several new firm-level models of international trade with heterogeneous firms predict that industry productivity will rise as trade costs fall due to the reallocation of activity across plants within an industry. Using disaggregated U.S. import data, we create a new measure of trade costs over time and industries. As the models predict, productivity growth is faster in industries with falling trade costs. We also find evidence supporting the major hypotheses of the heterogenous-firm models. Plants in industries with falling trade costs are more likely to die or become exporters. Existing exporters increase their shipments abroad. The results do not apply equally across all sectors but are strongest for industries most likely to be producing horizontally-differentiated tradeable goods.
We analyze the impact of rising import competition from China on U.S. innovative activities. Using Compustat data, we find that import competition induces R&D expenditures to be reallocated towards more productive and more profitable firms within each industry. Such reallocation effect has the potential to offset the average drop in firm-level R&D identified in the previous literature. Indeed, our quantitative analysis shows no adverse impact of import competition on aggregate R&D expenditures. Taking the analysis beyond manufacturing, we find that import competition has led to reallocation of researchers towards booming service industries, including business and repairs, personal services, and financial services.
This paper explores a newly available panel dataset merging balance sheet and international trade transaction data for Belgium. Both imports and exports appear to be highly concentrated among few firms and seem to have become more so over time. Focusing on manufacturing, we find that facts previously reported in the literature as applying only to exports actually apply to imports too. We note that the number of trading firms diminishes as the number of export destinations or import origins increases. The same is true if we consider the number of products traded. Our results generally point to a process of self-selection in both export and import markets. Also, the productivity advantage of exporters reported in the literature may be overstated because imports were not considered. We find that firms that both import and export are the most productive, followed, in descending order, by importers only, exporters only and non-traders. Our results also show the existence of fixed costs of imports, which appear to be of similar magnitude as those of exports.
The COVID-19 pandemic has led to an unprecedented collapse in global economic activity and trade. The crisis has also highlighted the role played by global value chains (GVC), with countries facing shortages of components vital to everything from health systems to everyday household goods. Despite the vulnerabilities associated with increased interconnectedness, GVCs have also contributed to increasing productivity and long-term growth. We explore empirically the impact of GVC participation on productivity in Estonia using firm-level data from 2000 to 2016. We find that higher GVC participation at the industry level significantly boosts productivity at both the industry and the firm level. Frontier firms, large firms, and exporting firms also benefit more from GVC participation than non-frontier firms, small firms, and non-exporting firms. We also find that GVC participation of downstream industries has a negative correlation with productivity. Frontier firms and large firms benefit more from GVC participation of upstream industries, while non-frontier firms and small firms benefit more from GVC participation of downstream industries. Our results suggest that policies designed to promote participation in GVCs are important to raise aggregate productivity and potential growth in Estonia.
This paper focuses on the sluggish growth of world trade relative to income growth in recent years. The analysis uses an empirical strategy based on an error correction model to assess whether the global trade slowdown is structural or cyclical. An estimate of the relationship between trade and income in the past four decades reveals that the long-term trade elasticity rose sharply in the 1990s, but declined significantly in the 2000s even before the global financial crisis. These results suggest that trade is growing slowly not only because of slow growth of Gross Domestic Product (GDP), but also because of a structural change in the trade-GDP relationship in recent years. The available evidence suggests that the explanation may lie in the slowing pace of international vertical specialization rather than increasing protection or the changing composition of trade and GDP.
The essays in this book explore the forces behind modern economic growth and, in particular, the causes of the extraordinary surge of growth since the Second World War. The introductory essay is an extended treatment of how economists now view the growth process and its causes. Other essays consider the contributions of capital formation, education, and the changed nature of industries and occupations. Professor Abramovitz asks why elevated incomes failed to bring the social progress and personal satisfaction that people had looked for. The final chapters in the book take up the causes of our discontent and consider whether the Welfare State has itself become an obstacle to further economic progress.The essays in this book explore the forces behind modern economic growth and, in particular, the causes of the extraordinary surge of growth since the Second World War.
