Trade and productivity: Self-selection or learning-by-exporting in India

Recent literature tried to explain the Indian growth miracle in different ways, ranging from trade liberalization to industrial reforms. Using data on Indian manufacturing firms, this paper analyzes the relationship between firm's productivity and export market participation during 1991–2004. While it provides evidence of the self-selection hypothesis by showing that more productive firms become exporters, the results do not show that entry into export markets enhances productivity. The paper examines the explanation of self selection hypothesis for total factor productivity differences across 33,510 exporting and non-exporting firms. It uses propensity score matching to test the learning-by-exporting hypothesis. In line with the prediction of recent heterogeneous firm models of international trade, the main finding of the paper is: more productive firms become exporters but it is not the case that learning by exporting is a channel fuelling growth in Indian manufacturing.     

Productivity growth in British manufacturing: spatial variation in the role of scale economies,technological growth and industrial structure

This paper investigates the role of scale economies, technological growth and industrial structure in creating spatial variation in manufacturing labour and Total Factor (TFP) productivity in Britain. Separate estimates of a translog specification are presented for British manufacturing firms located in defined areas of the country over the period 1994–1998. The results show that TFP change due to scale economies and technological growth has been of much less important in influencing the output growth of manufacturing firms than input growth or industrial structure. Regarding the components of TFP, technological growth has been the dominant force at play. The analysis of average labour productivity identifies shifts to other factors of production and industrial structure as being the main determinants of change, scale economies appear to have had a marginal role. The results identify spatial patterns indicating that more favourable locational effects arise for firms in areas adjacent to large urban centres, rather than for those located within cities, on the extreme periphery of the urban hinterland, or in rural areas and smaller towns.     

Outsourcing and firm productivity: a production function approach

This paper is aimed at analyzing the relationship between outsourcing and productivity. Specifically, this paper deals with outsourcing at the firm level and focuses on the role of contracting out of manufacturing activities. I obtain new insights on this topic, mainly using a precise measure for outsourcing and analyzing differences across industries. Using an unbalanced panel of Spanish manufacturing firms, I estimate a production function depending on traditional inputs (labor, capital, and materials) and an index of production subcontracting. I find that for manufacturing as a whole, outsourcing intensity has a positive effect on productivity, showing an elasticity of output with respect to outsourcing around 0.15. When analyzing industry level results, I find that outsourcing intensity has a positive effect on productivity, mainly for firms belonging to light industries.     

Productivity growth from an international trade perspective

This paper presents a framework to assess the relative importance of three key sources of productivity growth that international trade research focuses on: (1) inter‐industry specialization; (2) intra‐industry reallocation of resources across heterogeneous firms; and (3) technological progress. We illustrate how to apply the framework by deciphering the productivity dynamics of the Swiss manufacturing industry. We find that intra‐industry reallocations are the most important source of growth in aggregate total factor productivity, spurred by the productivity growth of large, incumbent firms and the entry of new firms. Inter‐industry specialization and general technological progress, nevertheless, remain important supplementary sources of productivity growth.     

Competition and the relative productivity of large and small firms

Using a comprehensive dataset on the incidence of price-fixing across British manufacturing industries in the 1950s, I compare collusive and competitive industries and find evidence of a negative relationship between collusion and the labour productivity of larger firms relative to smaller firms. In particular, collusion is associated with a reduction or even a reversal of the productivity gap between larger and smaller firms. This result is robust to controlling for the potential endogeneity of collusion.     

Regional foreign direct investment and technology spillover: evidence across different clusters in India

This paper examines whether there exist productivity spillovers from foreign direct investment (FDI) to domestic firms at the regional level, using firm-level panel dataset covering 22 manufacturing industries in India from 2000 to 2012. In order to estimate the productivity spillovers from FDI at the regional level, we select 10 industrial clusters across 4 regions in India. In estimating productivity, we control for a possible simultaneity bias by using semi-parametric estimation techniques. We find that local firms benefit from horizontal and vertical FDI, but the benefits from the latter are found to be substantially stronger. The absorptive capacity of domestic firms is highly relevant to harvest the spilled technology from foreign-owned firms. Furthermore, we find that domestic firms belonging to high-technology industries benefit more from FDI at the regional level. We also find that market concentration is a crucial conduit for firm innovation, technological upgradation, and having a direct effect on local firm total factor productivity.     

Productivity spillovers through backward linkages: The role of the origin of investors and absorptive capacity of domestic firms

We argue that multinationals from different home countries have different technologies and input sourcing behavior. These differences impinge on potential productivity spillovers through backward linkages of multinationals and such effects also differ across host local firms depending on their absorptive capacity. Using a panel of Cameroonian manufacturing firms over the period 1993 to 2005, we find supportive evidence of these arguments. There is a negative relationship between the presence of American and European affiliates in downstream sectors and the productivity of Cameroonian firms in the supplying industries and a positive correlation in the case of Asian affiliates. The absorptive capacity of Cameroonian firms mainly explains these divergent results.     

The relationship among enterprise clustering,prices, and productivity in Ethiopia’s manufacturing sector

We use census panel data on Ethiopian manufacturing firms to analyze how enterprise clustering in local markets covaries with firm‐level output prices and physical productivity. We find a negative and statistically significant relationship between the density of firms that produce a given product in a given location and the local price of that product. We also find a positive and statistically significant relationship between the density of firms that produce a given product in a location and the physical productivity of same‐product firms in the location. These results are consistent with the notion that increased clustering of firms generates higher competitive pressure and positive externalities. Across firms that produce different products, we find no statistically significant relationship between enterprise clustering and firm‐level output prices and productivity. We also find no clustering effects across towns. Our results suggest that while clustering can impact firm performance, the advantages are narrow in scope.     

Tariff reduction and employment in Canadian manufacturing

Abstract.  This paper uses firm-level tax data to investigate whether the link between tariff changes and manufacturing employment differed across firms with various productivity and leverage characteristics over the period 1988–94. The results suggest that the effect of domestic tariff reductions on employment was typically small, but that losses were significantly larger for less productive firms. For instance, firms with average productivity in 1988 responded to domestic tariff changes by cutting employment by 11.3% over the period 1988–94, while lower-productivity firms typically shed 20.8% of their workforce over the same period. This paper also indicates that firms with unhealthy balance sheets – those with relatively too much equity or too much leverage – downsized more in the face of declining domestic tariffs, suggesting that financial constraints became more binding when tariff cuts were implemented. These results suggest that firms with high productivity and better financial health were better positioned to face the challenge of trade liberalization.     

Distant but Close in Sight: Firm-level Evidence on French–German Productivity Gaps in Manufacturing

We study productivity-level distributions of manufacturing firms in France and Germany, and how these distributions evolved across the Great Recession. We show the presence of a systematic productivity advantage of German firms over French ones in the decade 2003–2013, but the gap has narrowed down after the Great Recession. Convergence is explained by the better growth performance of French firms in the post-recession period, especially of those located in the top percentiles of the productivity distribution. We also highlight the role of sectoral growth, firm size, and export intensity in explaining the above convergence. In contrast, the contribution of allocative efficiency was small.     

Innovation and productivity in manufacturing and service firms in Catalonia: a regional approach

This article analyses the determinants of research and development (R&D) and the role of innovation on labour productivity in Catalan firms. Our empirical analysis found a considerable heterogeneity in firm performances between the manufacturing and service industries and between low- and high-tech industries. The frontiers that separate manufacturing and service industries are increasingly blurred. In Catalonia high-tech knowledge-intensive services (KIS) play a strategic role in promoting innovation in both manufacturing and service industries, and driving growth throughout the regional economy. Empirical results show new firms created during the period 2002–2004 that have a greater R&D intensity than incumbent firms (54.1% in high-tech manufacturing industries and 68.8% in high-tech KIS). Small and young firms in the high-tech KIS sector are very prone to carrying out R&D and they invest more in innovation projects. R&D expenditures, output innovation, investment in physical capital, market share and export have positive effects on labour productivity in both the manufacturing and service sectors. Firm size, on the other hand, has a positive effect on productivity in manufacturing industries but not in services.     

An empirical study of firm productivity growth based on the dynamic selection model: Effects on the recent decline in Korean exports

Export and productivity growth in the Korean manufacturing sector have both been slow since 2011. To understand this relationship, we examine the productivity distributions of manufacturing firms in Korea by applying the dynamic selection model developed by Sampson (2016). The fitness of the dynamic selection model suggests that a slowdown in the market selection mechanism may be a crucial contributor to the stagnant growth in the productivity. In addition, we find that the productivity difference between exporting firms and non-exporting firms has decreased and the low productivity growth of firms exporting to non-foreign affiliates has contributed to this trend.     

Multinational production,exports and aggregate productivity

This paper presents and estimates a dynamic model of multinational production (MP) and exports with heterogeneous firms. The model highlights the interaction between firms' location and export decisions and their effect on aggregate productivity. The model is structurally estimated using firm-level Indonesian manufacturing data. The results are broadly consistent with the pattern of productivity, exports and MP across firms. Counterfactual experiments suggest that there are substantial productivity gains due to international trade and MP. The implied changes in steady state real wages, however, are relatively small. The experiments emphasize that the nature of firm-level trade and MP interactions are crucial to determining the aggregate effects of trade and foreign direct investment policy.     

Does international openness affect the productivity of local firms?

This paper examines how international openness can change firm productivity in south‐eastern Europe (SEE), a crucial question for middle‐income countries. Using firm‐level data for six transition economies over the 1995–2002 period, we identify whether foreign ownership and propensity to trade with more advanced countries can bring about higher learning effects. We find that: (i) foreign ownership has helped restructure and enhance the productivity of local firms in four out of six countries; (ii) exporting to advanced markets has a larger impact on productivity growth in four countries, especially when the firm's absorptive capacity is taken into account; (iii) in contrast, exporting to the less competitive markets of the former Yugoslavia seems to negatively affect productivity growth in three countries; and (iv) learning effects from importing are similar to those from exporting. Our results suggest that trade liberalization is not uniformly beneficial. Regional composition of trade flows and absorptive capacity of local firms matter. Thus, trade liberalization within the SEE region may not provide a substitute for a general trade liberalization which includes access to the more competitive markets of countries belonging to the Organization for Economic Co‐operation and Development.     

Trade Liberalization and Firm Productivity: Evidence from Chinese Manufacturing Industries

This paper examines the impact of tariff reduction following China's World Trade Organization (WTO) entry on the productivity of Chinese manufacturing firms using a firm‐level panel database that comprises all of China's manufacturing firms with an annual turnover above 5 million yuan and that spans the period of 2000–2006. An instrumental variable estimator is used to account for the endogeneity of the tariff reduction. The results indicate that China's trade liberalization in the five years following its WTO entry has led to a 0.94% annual increase in total factor productivity for Chinese manufacturing firms. However, the overall productivity gain from the tariff reduction is a net result of a productivity depressing effect of output tariff reduction and a productivity enhancing effect of input tariff reduction. Both effects have diminished in magnitude over the years after China joined the WTO. Firm heterogeneity and turnover plays an important role in generating gains from trade liberalization. The surviving firms have managed to cope with and take advantage of lower tariffs. The extent to which the tariff reduction affects Chinese firms' productivity is also dependent on the ownership structure of the firms with foreign‐invested firms being the clear winner.     

Offshore Outsourcing and Productivity: Evidence from Japanese Firm‐level Data Disaggregated by Tasks

This paper examines the relationship of offshoring with productivity, based on the original survey data of Japanese firms. Productivity gains were found in the firms offshoring both manufacturing and service tasks, but not in the firms offshoring only either manufacturing or service tasks. This paper also finds that firms offshoring to various destinations tend to be more productive than non‐offshoring firms. These results suggest that the level of firms' engagement in offshoring is more important for productivity than whether or not firms engage in offshoring.     

Why firms set different export prices? Evidence from Spain

Using firm-level export data for the 2010–2014 period, we investigate the variation of export prices across and within Spanish manufacturing firms. We find that more productive firms set higher export prices. However, this result is not robust to controlling for other firm-level characteristics and alternative productivity measures. We show that firms set higher export prices in more distant markets and in destinations with high GDP per capita, and lower export prices in large and low-competition markets. These latter results suggest that firms adjust the quality of their products to destination characteristics.     

Firm innovation and productivity in Europe: evidence from innovation-driven and transition-driven economies

This article examines the links between firm innovation and firm productivity performance across a range of European economies, and in particular, we explore the differences between countries which are in transition from efficiency-driven to innovation-driven with those which are primarily innovation-driven economies. We employ an endogenous-switching technique to explore micro-economic survey-based data from both innovating and noninnovating firms. The model allows us to construct counterfactual scenarios which overcome problems of self-selection in the data. Some of the findings provide support for the traditional patterns previously found in the innovation literature, in which innovation efforts and investments in physical and human capital are found to be important for product and process innovations in manufacturing and service firms and across economy types. Our counterfactual analysis also allows us to outline a rationale for policy intervention towards noninnovating firms as well as innovating firms depending on where the transitional heterogeneity effects are greatest.

The effects of economic reforms on manufacturing dualism: Evidence from India

Dualism is a pervasive feature of the manufacturing sectors of less-developed countries, with large differences in productivity between the informal and the formal sectors. Policy distortions are viewed as an important factor behind the prevalence of manufacturing dualism. We examine whether tariff reforms, industrial de-licensing and the withdrawal of reservation of products for small firms implemented since the mid-1980s have had any effects on efficiency differentials between informal and formal firms in Indian manufacturing. We find strong evidence that economic reforms have exacerbated dualism by increasing the productivity differentials between the more efficient formal firms and the less efficient informal firms.
