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.

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.




China and ASEAN: Pivoting Trade and Shock Transmission


Book Description

This book highlights the critical relationship between China and the Association of Southeast Asian Nations (ASEAN) associated with its trade interdependency. As the largest trade partner in the region, China has not only presented itself with opportunities for ASEAN to tap its market, but also created great challenges for the region. The fundamental question that this book addresses, therefore, is whether China’s engagement with ASEAN comes at a cost for the latter following from the systemic risks tied to the China-centric supply chains in the region. The trade interactions between China and ASEAN, though extensively explored, are less understood in the context of its influence over the region amidst the recent changing dynamics that follow from China’s global engagement and backlash from major powers. The book therefore resolutely rises against stereotypes and clichés, making readers reconsider many oversimplified assumptions of the benefits of trade engagement where economies are interconnected through complex production chains.




From Firm-Level Imports to Aggregate Productivity


Book Description

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.




The Impact of Remittances on Economic Activity: The Importance of Sectoral Linkages


Book Description

We propose a simple macroeconomic model with input-output sectoral linkages based on Acemoglu et al. (2016) to quantify how changes in aggregate demand due to additional income from household’s remittances propagates through the network of input-output linkages in Sub-Saharan African countries. We first propose two network centrality measures to assess the role of some sectors as key input providers in the economy. Then, we use these measures to quantify the effect of sectoral linkages on sectoral and total output following an increase in remittances inflows. Our empirical results suggest that the effects of remittances on recipient economies increase with the degree of linkages across sectors, which is especially prominent in the case of the financial intermediation sector. Our paper contributes to the emerging macroeconomic literature on the propagation of shocks across sectors and the implications for the whole economy.




COVID-19 and Emerging Markets


Book Description

Abstract: We quantify the macroeconomic effects of COVID-19 for a small open economy by calibrating a SIR-multi-sector-macro model to Turkey. Sectoral supply shocks are based on the proximity requirements in each sector and the ability to work from home. Physical proximity determines the supply shock through its effect on infection rates. Sectoral demand shocks incorporate domestic and foreign demand, both of which adjust with infection rates. We calibrate demand shocks during COVID-19 using real-time credit card purchase data. Our results show that the optimal policy, which yields the lowest economic cost and saves the maximum number of lives, can be achieved under a full lockdown of 39 days. Economic costs are much larger for an open economy as the shocks are amplified through the international production network. A decline in foreign demand leads to losses in domestic sectors through international input-output linkages, accounting for a third of the total output loss. In addition, the reduction in capital flows deprives the network from its trade financing needs, where sectors with larger external finance needs experience larger losses. The policy options are limited given sparse fiscal resources to fight the pandemic domestically, while serving the external debt. We present historical evidence from 2001 crisis of Turkey, when fiscal, monetary and exchange rate policies were employed altogether to deal with a triple crisis of balance of payments, banking, and sovereign debt




Changing Patterns of Global Trade


Book Description

Changing Patterns of Global Trade outlines the factors underlying important shifts in global trade that have occurred in recent decades. The emergence of global supply chains and their increasing role in trade patterns allowed emerging market economies to boost their inputs in high-technology exports and is associated with increased trade interconnectedness.The analysis points to one important trend taking place over the last decade: the emergence of China as a major systemically important trading hub, reflecting not only the size of trade but also the increase in number of its significant trading partners.




Technology Shocks and Aggregate Fluctuations


Book Description

Our answer: Not so well. We reached that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the strong positive comovement between output and labor input measures.




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.
