Trade Linkages and International Business Cycle Comovement: Evidence from Korean Industry Data


Book Description

Through the 2000s, Korea’s export and import linkages to advanced and emerging markets increased significantly. At the same time, the correlation of output growth between Korea and these economies rose. This paper investigates the nature of the link between trade linkages and the comovement of international business cycles (BC) using Korean industry-level domestic and international input-output data. The results suggest that, at the industry-level, higher export linkages lead to a larger positive GDP growth comovement, while higher import linkages lead to higher negative employment growth comovement. Furthermore, the decomposition of aggregate BC comovement shows that the increase in trade with China has contributed the most to aggregate BC comovement, while the impact of trade linkages on BC comovement is propagated domestically via vertical linkages. These findings suggest that the Korean economy can be significantly affected by a few countries that are highly linked through trade to Korea and/or a few industries that are highly interconnected to other industries.

Transmission of Domestic and External Shocks through Input-Output Network: Evidence from Korean Industries


Book Description

In the last two decades, manufacturing industries in Korea have become more concentrated, and interconnectedness across industries and to foreign countries has risen via vertical relationships and trade linkages. This paper investigates the transmission of economic shocks in such a highly concentrated and interconnected structure, focusing on the role of vertical and trade linkages and using the industry-level international input-output data. The results suggest that, first, the role of vertical and trade linkages in propagating growth shocks from both domestic sources and external sources is important. Second, the growth impact of a few key sources of economic shocks is relatively large. These findings highlight that economic shocks in a few key industries and/or major trading partners that are transmitted through vertical and trade linkages can lead to large swings in the overall economy. This paper contributes to the understanding of the potential interactions between the industrial structure and economic growth and stability.




Global Business Cycles


Book Description

This paper analyzes the evolution of the degree of global cyclical interdependence over the period 1960-2005. We categorize the 106 countries in our sample into three groups-industrial countries, emerging markets, and other developing economies. Using a dynamic factor model, we then decompose macroeconomic fluctuations in key macroeconomic aggregates-output, consumption, and investment-into different factors. These are: (i) a global factor, which picks up fluctuations that are common across all variables and countries; (ii) three group-specific factors, which capture fluctuations that are common to all variables and all countries within each group of countries; (iii) country factors, which are common across all aggregates in a given country; and (iv) idiosyncratic factors specific to each time series. Our main result is that, during the period of globalization (1985-2005), there has been some convergence of business cycle fluctuations among the group of industrial economies and among the group of emerging market economies. Surprisingly, there has been a concomitant decline in the relative importance of the global factor. In other words, there is evidence of business cycle convergence within each of these two groups of countries but divergence (or decoupling) between them.




Republic of Korea


Book Description

This 2019 Article IV Consultation discusses Korea’s economy that has strong fundamentals; however, it is facing cyclical and structural headwinds. Potential growth will continue its decline, and polarization and inequality are concerns. Labor and product market duality persist. The government is focusing on supporting income, creating jobs, and promoting innovation. The government has focused on supporting income, creating jobs, and promoting innovation. It has strengthened social safety nets, substantially raised the minimum wage, supported small-and-medium enterprises to boost employment, and expanded public sector jobs. Fiscal policy should remain expansionary in the medium term, focusing on increasing social protection, boosting female labor force participation, and supporting growth enhancing structural reforms. Public sector job creation should be linked to developing services that cannot be provided by the private sector. The minimum wage increase for next year should be set below labor productivity growth. The IMF staff recommend an integrated package of macroeconomic, financial and structural policies to support growth, raise potential output, and reduce excess internal and external imbalances, while preserving financial stability.




Power Laws in Firm Size and Openness to Trade


Book Description

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in absolute value than the power law exponent among non-exporting rms. We use a dataset of French firms to demonstrate that this prediction is strongly supported by the data. While estimates of power law exponents have been used to pin down parameters in theoretical and quantitative models, our analysis implies that the existing estimates are systematically lower than the true values. We propose two simple ways of estimating power law parameters that take explicit account of exporting behavior.




Firm Innovation and Productivity in Latin America and the Caribbean


Book Description

This volume uses the study of firm dynamics to investigate the factors preventing faster productivity growth in Latin America and the Caribbean, pushing past the limits of traditional macroeconomic analyses. Each chapter is dedicated to an examination of a different factor affecting firm productivity - innovation, ICT usage, on-the-job-training, firm age, access to credit, and international linkages - highlighting the differences in firm characteristics, behaviors, and strategies. By showcasing this remarkable heterogeneity, this collection challenges regional policymakers to look beyond one-size-fits-all solutions and create balanced policy mixes tailored to distinct firm needs.

World Development Report 2020


Book Description

Global value chains (GVCs) powered the surge of international trade after 1990 and now account for almost half of all trade. This shift enabled an unprecedented economic convergence: poor countries grew rapidly and began to catch up with richer countries. Since the 2008 global financial crisis, however, the growth of trade has been sluggish and the expansion of GVCs has stalled. Meanwhile, serious threats have emerged to the model of trade-led growth. New technologies could draw production closer to the consumer and reduce the demand for labor. And trade conflicts among large countries could lead to a retrenchment or a segmentation of GVCs. World Development Report 2020: Trading for Development in the Age of Global Value Chains examines whether there is still a path to development through GVCs and trade. It concludes that technological change is, at this stage, more a boon than a curse. GVCs can continue to boost growth, create better jobs, and reduce poverty provided that developing countries implement deeper reforms to promote GVC participation; industrial countries pursue open, predictable policies; and all countries revive multilateral cooperation.




Making It Big


Book Description

Economic and social progress requires a diverse ecosystem of firms that play complementary roles. Making It Big: Why Developing Countries Need More Large Firms constitutes one of the most up-to-date assessments of how large firms are created in low- and middle-income countries and their role in development. It argues that large firms advance a range of development objectives in ways that other firms do not: large firms are more likely to innovate, export, and offer training and are more likely to adopt international standards of quality, among other contributions. Their particularities are closely associated with productivity advantages and translate into improved outcomes not only for their owners but also for their workers and for smaller enterprises in their value chains. The challenge for economic development, however, is that production does not reach economic scale in low- and middle-income countries. Why are large firms scarcer in developing countries? Drawing on a rare set of data from public and private sources, as well as proprietary data from the International Finance Corporation and case studies, this book shows that large firms are often born large—or with the attributes of largeness. In other words, what is distinct about them is often in place from day one of their operations. To fill the “missing top†? of the firm-size distribution with additional large firms, governments should support the creation of such firms by opening markets to greater competition. In low-income countries, this objective can be achieved through simple policy reorientation, such as breaking oligopolies, removing unnecessary restrictions to international trade and investment, and establishing strong rules to prevent the abuse of market power. Governments should also strive to ensure that private actors have the skills, technology, intelligence, infrastructure, and finance they need to create large ventures. Additionally, they should actively work to spread the benefits from production at scale across the largest possible number of market participants. This book seeks to bring frontier thinking and evidence on the role and origins of large firms to a wide range of readers, including academics, development practitioners and policy makers.
