The empirical evidence linking economic reform in developing countries with gains in productivity and efficiency is both limited and inconclusive. Using large firm-level data collected by the Reserve Bank of India, this book examines the impact of reform on productivity and competition for the Indian manufacturing sector in the eighties. Relying on econometric estimates of pre- and post-reform productivity growth, the study finds evidence of significantly higher productivity growth rates after the mid-eighties both at the aggregate and two-digit sector levels. The author seeks corroborating evidence by developing a framework that enables him to simultaneously estimate economies of scale, a measure of optimal labour utilization and the mark-up of price over marginal cost as an indicator of competitiveness. Though he finds evidence of better labour utilization, there is no indication of reduced market power or any significant departure from constant returns to scale in the post-reform period. He concludes that even the limited reforms of the eighties led to productivity gains which were achieved largely through better resource use.
This paper reassesses the impact of trade liberalization on productivity. We build a new, unique database of effective tariff rates at the country-industry level for a broad range of countries over the past two decades. We then explore both the direct effect of liberalization in the sector considered, as well as its indirect impact in downstream industries via input linkages. Our findings point to a dominant role of the indirect input market channel in fostering productivity gains. A 1 percentage point decline in input tariffs is estimated to increase total factor productivity by about 2 percent in the sector considered. For advanced economies, the implied potential productivity gains from fully eliminating remaining tariffs are estimated at around 1 percent, on average, which do not factor in the presumably larger gains from removing existing non-tariff barriers. Finally, we find strong evidence of complementarities between trade and FDI liberalization in boosting productivity. This calls for a broad liberalization agenda that cuts across different areas.
In the past ten years the Brazilian economy has experience an unprecedented wave of market liberalization as import substitution has been progressively abandoned in favour of integration into the global economy. Trade barriers have fallen, privatizations have been implemented, and government procurement has been cut back. Although these policy shifts will be familiar to many, their implications in terms of performance may not. Using a comprehensive array of primary and secondary sources and in-depth company case studies, this book examines how one vitally important Brazilian industrial sector-the non-serial capital goods sector-coped with the onset of liberalization. While liberalization undoubtedly helped to promote greater efficiency in some areas of corporate performance, the impact elsewhere was far less favourable. This differentiated response raises some interesting and troubling theoretical and policy issues.
This chapter reviews the empirical economics literature on the impact of trade liberalization on firms' innovation-related outcomes. We define and examine four types of shocks to trade flows: import competition, export opportunities, access to imported intermediates, and foreign input competition. Our review reveals interesting heterogeneities at the country and firm levels. In emerging countries, trade liberalization appears to spur productivity and innovation. In developed countries, export opportunities and access to imported intermediates tend to encourage innovation, but the evidence on import competition is mixed, especially for firms in the United States. At the firm level, the positive effects of trade on innovation are more pronounced at the initially more productive firms while the negative effects are more pronounced at the initially less productive firms.
Does competition spur productivity? And if so, how? These have long been regarded as central questions in economics. The extent of competition can be influenced by policy decisions, so understanding how competition impacts productivity and, in turn, living standards is of more than academic importance. To fully answer these questions of whether, and how, an increase in competition impacts productivity, two issues must be addressed. First, the authors define what we mean by an ¿increase in competition.¿ Second, they attempt to understand the mechanisms through which competition impacts productivity. Both issues present substantial challenges, which the authors address. Illustrations. This is a print-on-demand publication; it is not an original.
This paper studies the macroeconomic effect and underlying firm-level transmission channels of a reduction in business entry costs. We provide novel evidence on the response of firms' entry, exit, and employment decisions. To do so, we use as a natural experiment a reform in Portugal that reduced entry time and costs. Using the staggered implementation of the policy across the Portuguese municipalities, we find that the reform increased local entry and employment by, respectively, 25% and 4.8% per year in its first four years of implementation. Moreover, around 60% of the increase in employment came from incumbent firms expanding their size, with most of the rise occurring among the most productive firms. Standard models of firm dynamics, which assume a constant elasticity of substitution, are inconsistent with the expansionary and heterogeneous response across incumbent firms. We show that in a model with heterogeneous firms and variable markups the most productive firms face a lower demand elasticity and expand their employment in response to increased entry.
