THE RELATIONSHIP BETWEEN EXPORT STATUS AND PRODUCTIVITY IN SERVICES: A FIRM‐LEVEL ANALYSIS FOR SPAIN

This paper analyses the relationship between export status and productivity in a major service exporter, Spain, during 2001–07. I find that exporters in the services sector are 45 percent more productive than non‐exporters. This productivity premium is larger for firms that supply non‐internet‐related services than for firms that supply internet‐related services. The results show that exporters were more productive than non‐exporters before beginning to export, and also that exporting increases productivity growth; however, this positive shock vanishes quickly.     

The contribution of granular and fundamental comparative advantage to European Union countries' export specialisation

This paper analyses the contribution of fundamental comparative advantage (a country-specific component) and granular comparative advantage (a firm-specific component) to European Union countries' export specialisation. We find that, on average, granular comparative advantage may explain export specialisation in 29% of industries, which account for 47% of total exports. We also show that 60% of the variation in export specialisation across countries and industries may be explained by granular comparative advantage. These results highlight that some outstanding firms may play a very important role in explaining European Union countries' export specialisation.     

The variation of export prices across and within firms

This paper uses transaction-level trade data to analyze the differences in export prices across and within Spanish firms exporting manufactures in the 2010–2014 period. The transactional nature of the database uncovers sizable differences in the price that an exporter charges for the same product and destination. These differences are related with the number of goods covered within each product category, the exported quantity per transaction and the number of transactions carried out by firms.     

Export revenue and quality: Firm‐level evidence from developing countries

I combine firm‐level export data from eight low‐income and middle‐income countries to test the relation between export price and export revenue. Across‐firm estimations show a strong positive association between export price and export revenue. Within‐firm estimations show that firms generate larger export revenue from their high‐price products. The positive correlation between export price and export revenue is strong for manufactures, weak for primary commodities, and nonexistent for extractables. Results are robust to using an alternative quality measure and controlling for exporters’ market power.     

THE CONVERGENCE IN PRODUCT‐LEVEL RELATIVE PRODUCTIVITY ACROSS PROVINCES

This paper uses highly disaggregated data to analyze the convergence process in product‐level relative productivity across Spanish provinces. Over the period 1988‐2013 there is a 53 per cent reduction in product‐level relative productivity differences across provinces. The speed of convergence in product‐level productivity is faster than in income per capita. Provinces that are geographically close, have strong ties and share similar factor endowments become more similar in product‐level relative productivities.     

The extensive and intensive margins of Spanish trade

Recent empirical research highlights that differences in trade flows across countries, products and years are governed by two margins: the intensive margin and the extensive margin. The analysis of the relative contribution of each margin is very important to determine which policies can be more efficient to foster trade at the aggregate, geographic, product or firm level. We use the whole universe of firm level transaction data to analyse the relative contribution of these margins to changes in Spanish trade flows during the 1997–2007 period. We first apply the methodology proposed by Bernard et al. (2009 Bernard, A.B., Jensen, J.B., Redding, S.J. and Schott, P.K. 2009. The margins of US trade. American Economic Review: Papers & Proceedings, 99(2): 487–93. [Crossref], [Web of Science ®] [Google Scholar]) to decompose trade variation over time into three components: net entry of firms, product-country switching and value growth by regular trading firms. The first two components correspond to the extensive margin and the last one refers to the intensive margin. We find that short-run changes in exports and imports are governed by firms’ intensive margin; however, in the long-run, both the extensive and the intensive margins are equally important to foster trade. We also examine the importance of the trade margins at the cross-sectional level for the year 2007. We find that large differences in the Spanish trade flows across countries and products, especially in the case of exports, are explained by the number of firms that participate in trade, which is consistent with the fact that the number of trading partners decline significantly with distance.     

Networks and the Dynamics of Firms' Export Portfolio: Evidence for Mexico

We use network analysis tools to identify communities in the web of exporters' destinations. Our network‐based community measure is purely outcome based, it captures multilateral rather than bilateral dependence across countries, and it can be calculated at the industry level. Next, we use our network‐based community measure as predictor of additional countries chosen by firms expanding their export destination portfolio. Using data on Mexican new exporters, the probability of choosing a new export destination doubles if it belongs to the same community of any of the firm's previous destinations. The introduction of the network‐based community variable improves the accuracy of the model up to 19 per cent relative to a model that only includes gravity variables. Industry‐specific communities and general communities play similar roles in determining the dynamics of Mexican exporters' country portfolio.     

Does complexity explain the structure of trade?

This paper analyzes whether complexity, measured by the number of skilled tasks that are performed in production, explains countries’ commodity trade structure. We modify the Romalis ( 2004 ) model to incorporate advantage differences in complexity across commodities together with differences in the number of mistakes made by workers in the production process in developed and developing countries as a source of comparative advantage. Our model predicts that the share of developed countries in world trade increases with products’ complexity. Empirical tests confirm this prediction. Moreover, we find that complexity complements the explanation provided by skill‐intensity on countries’ commodity trade structure.     

Is competition from China so special?

Competition from China is perceived as particularly damaging. We study whether this is true for firm performance. Using the universe of Spanish export transactions, we find that an increase in competition from China does not have a more damaging effect on export revenues, prices and number of exported products than an equally sized increase in competition from other countries. We document, though, that Chinese competition raises the probability that a firm ceases to export a good to a destination more than competition from other countries. This effect declines over time. We document an omitted variable bias in studies focusing only on Chinese competition, even when controlling for unobserved heterogeneity of destinations for different products within firms.     

Does comparative advantage explain countries’ diversification level?

This paper analyses whether the products in which a country has comparative advantage can explain its exports’ diversification level. We argue that specialisation endows countries with some specific skills and assets; in some cases those skills and assets can easily be redeployed in other products and facilitate diversification, whereas in other cases skills and assets are more difficult to redeploy and offer scant diversification possibilities. Based on countries’ comparative advantage and an index of product proximity, we construct a metric for countries’ diversification possibilities. Using non-parametric and parametric techniques, we show that this metric is a very strong and robust predictor of countries’ actual diversification level, even when we control for differences in income across countries. These results point out that diversification may not be an automatic outcome of development.
