The literature on trade liberalization has recently shifted its attention from trade liberalization in imported final goods to studying the effects of trade liberalization in imported intermediate inputs. This emphasis fits very well the trade liberalization experience of China following its accession to the WTO in 2001. We build a multi-sector heterogenous-firm model with trade in both intermediate goods and final goods, and we ask: How do final-goods producers respond to trade liberalization in imported inputs? Do they respond differently across sectors? How do firms respond differently to trade liberalization in imported-outputs instead? We decompose the total effect of trade liberalization into those caused by inter-sectoral resource allocation (IRA) and by within-sector selection of firms according to productivity (which we call Melitz selection effect). It is the IRA effect that gives rise to differential impacts of trade liberalization in different sectors. These impacts include changes in the probability of entry into the export market, the fraction of firms that export and the share of export revenue. We test our hypotheses using Chinese firm-level data for the years after China's accession to WTO in 2001. The results generally support our hypotheses.
Output among firms is likely to be reallocated as a result of trade liberalization. In imperfectly competitive industries, such a "rationalization" effect can be an important component of the welfare impact of trade reform.
We investigate theoretically and empirically the role of wholesalers in mediating the productivity effects of trade liberalization. Intermediaries provide indirect access to foreign produced inputs. The productivity effects of input tariff cuts on firms that do not directly import therefore depends on the extent that wholesalers are a feature of input supply within an industry. Using firm level data from China, we document that wholesalers play no such role for direct importers. However, other firms experience productivity gains from reducing input tariffs if trade intermediation of foreign inputs within their sector is high. They suffer efficiency losses otherwise.
This book examines driving factors and the effects of globalisation on economic development through firm and product-level data. The book is organised into four themes, i.e., productivity, innovation, wage and income gap, and within-firm reallocation of resources. The comprehensiveness and richness of firm and product-level data shed light upon the channels through which trade and investment affect firms’ competitiveness and unveil factors shaping firms’ heterogeneous responses towards globalisation. The book looks at Asian economies as well as Australia and how they have experienced substantial structural change and become more integrated into the global economy and will be a useful reference for those who are interested in learning more about the relationship between globalisation and firm performance. This book will appeal to policy makers and researchers interested in the impact of globalisation on firm performance.
This book mainly focuses on the miracle of China’s foreign trade in the past 40 years from five perspectives: first, it briefly reviews the import substitution strategy China adopted before its opening-up; second, it analyzes the export-oriented strategy that contributes a lot to China’s economic growth since 1980s; third, it discusses the impacts of trade liberalization and China’s participation in WTO on Chinese firms; forth, it addresses the deepening opening-up in the context of global financial crisis; last, it provides policy advice on China’s newly conducted all-around opening-up strategy. By dividing China’s opening-up into five stages, this book offers a comprehensive discussion to understand and analyze the reason, performance and challenge of China’s economic growth from the perspective of foreign trade.
"This thesis investigates the impacts of changes in the trading environment on the behavior and performance of exportingfirms and of firms that import intermediate inputs. The thesis consists of three essays. Each essay contributesboth a theoretical development and an empirical analysis, using large scaled micro data from multiple sources. Thefirst essay studies how increased import penetration of inputs affects firms’ optimal mark-up and industry concentration.A theoretical model is developed to show how firms, operating under monopolistic competition, may choose toincur a fixed cost of foreign sourcing in order to replace some domestically sourced input with more efficient foreignsubstitutes. It is shown that changes in variable trade costs not only affect firms’ importing decision but also thenumber and identity of firms in the market and ultimately markups and market structure. We find evidence of a positiverelationship between imported input penetration and markup: the average markup rises when import penetrationincreases following a reduction in trade costs. The second essay develops a two-stage theoretical model to investigatehow firms’ decision on the number of varieties to export (i.e., their export scope) depends on exchange rate volatilityand on other characteristics of the destination countries. In the model, in the first stage, multi-product firms decide ontheir optimal product scope (the number of varieties to be produced for exporting), incurring fixed investment costs.In the second stage, they decide on the export scope for each destination country, based on country-specific tradecosts and expectation of idiosyncratic exchange rate shocks. Firms reduce their export scope to destination countriesthat suffer negative demand shocks, but they cannot increase their export scope beyond the production scope that theyhave chosen in the first stage. Using Chinese customs transaction data, we are able to provide empirical evidence thatsupports the predictions of our theoretical model. The third essay studies the effect of foreign tariff reductions on the adjustment of average quality and export scope of multi-product exporting firms, using China’s firm-level microdata and highly disaggregated customs data from 2000 to 2006. We find that in response to tariff cuts in destinationcountries, exporting firms upgrade product quality and adjust export scope. Our finding provides a novel explanationof what the phenomenon called incomplete tariff pass-through. A fall in the tariff rate seems to be associated with anincrease in the tariff-inclusive prices, but this is because the price data has not been adjusted to reflect the increase inproduct quality"--
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.
