Imports of Intermediate Inputs and Country Size
(World Bank, Washington, DC, 2014-01)The paper analyzes the relationship between country size and the use of imported intermediate inputs by firms in 76 developing countries. Recent evidence indicates that the use of imported inputs can have a large, positive effect on productivity and growth, thus motivating a better understanding of the determinants of foreign inputs. The results confirm that, as is the case with exports, use of imported intermediate inputs is much higher at the extensive and intensive margins in small relative to large countries. The results for imported inputs are comparable in magnitude with those for exports. -

Use of Imported Inputs and the Cost of Importing : Evidence from Developing Countries
(World Bank Group, Washington, DC, 2014-08)For a representative sample of manufacturing firms in 26 countries, this paper shows that changes in the cost of importing over time are significantly and negatively correlated with changes in the percentage of firms' material inputs that are of foreign origin. Furthermore, the paper shows that there may be a nonlinear relationship between import costs and imports. These findings are important, as recent studies point toward a significant positive effect of imported inputs on productivity and growth. It is hoped that the present paper inspires more work on the determinants of the use of imported inputs, especially in developing countries. -

Use of Imported Inputs and the Cost of Importing : Evidence from Developing Countries
(Taylor and Francis, 2014-08-26)For a representative sample of manufacturing firms in 26 countries, the article shows that changes in the cost of importing over time is significantly and negatively correlated with changes in the percentage of firm’s material inputs that are of foreign origin. Furthermore, we show that there may be a non-linear relationship between import costs and imports. These findings are important as recent studies point towards a significant positive effect of imported inputs on productivity and growth. We hope that the present article inspires more work on the determinants of imported input usage especially in developing countries. -

The Time Cost of Documents to Trade
(Taylor and Francis, 2015-06-04)The article shows that the number of documents required to export and import tend to increase the time cost of shipments. However, the increase in the time cost of increased documentation is much larger for countries that are relatively poor and large in size. One interpretation here is that the relatively rich countries that have more resources and the relatively small countries that rely more on trade invest more in building efficient documentation systems. Our findings suggest caution in interpreting how input-based measures, such as the number of required documents to trade, affect outcome measures. -

Decomposing the Labour Productivity Gap between Migrant-Owned and Native-Owned Firms in Sub-Saharan Africa
(Taylor and Francis, 2018-09-18)Migration studies have been primarily based on the movement of individuals from developing to developed economies, with a focus on the impact of migrants on host country wages. In this study we take a different angle by exploring the labor productivity of migrant-owned firms versus native-owned firms in 20 African economies using firm-level data. We find that labor productivity is 78 per cent higher in migrant-owned firms than native-owned firms. Using the Oaxaca-Blinder decomposition method we find that structural effects account for 80 per cent of the labor productivity gap. Returns to manager education largely explain the productivity advantage of migrant-owned firms over native-owned firms. Interactions with the government, access to finance, informality, and power outages are also considerable contributors to the labor productivity gap.
