Brooks (2016) paper attempts to account for rising connectivity and integration in East Asia. The paper explains how improvements in logistics and infrastructure services have influenced Asia's trade in goods and services. It also discusses the role of information and communication technologies and cross-border direct investment on production networks and intra-firm trade in East Asia. The paper is on an important topic, and provides interesting analyses and conclusions. The extent of connectivity and integration of East Asian economies has increased significantly, both regionally and globally. Empirical findings suggest that economic interdependence between emerging East Asian and major industrial countries continued to increase in the recent decades. In addition, Asian economies have become increasingly interdependent (Kim & Lee, 2012). China plays a central role in Asian production networks, and segmented production for global supply chains has stimulated trade and direct investment in the region, with China as a hub. Linking locations to enable the flow of goods, services, finance, technology, and people are certainly beneficial to the connected economies. As emphasized in Brooks (2016), a high degree of economic openness and integration was a vital ingredient of East Asia's success. Outward-looking export-led industrialization helped Asian economies grow rapidly by exploiting large external markets and imitating advanced technologies. Nonetheless, Brooks seems too credulous with the benefits of connectivity and integration. The global financial crisis of 2008–2009 highlights the risks of Asia's excessive dependence on exports. The region took a hit from the sharp decline in the demand for its exports, and saw many of its economies shrink. While Asian emerging economies were relatively resilient during the global recession, as strong and stable growth in China supported export-led recovery for the rest of Asia, the recent slowdown in Chinese economy triggers worries about sustained growth of Asian economies. The growth rate of China was 6.8% in 2015, the slowest since 1990, and it is expected to continue slowing down, which is a significant threat to the rest of Asia, in particular exporters of commodities and capital goods. It is debatable whether Asian economies should continue to promote integration and pursue export-led growth. Under current uncertain global environments and downside risks in China, emerging Asian economies must pursue appropriate policy measures to rebalance sources of growth and improve productivity (Kawai & Lee, 2015). Lee and McKibbin (2014) suggest that enhancing productivity in the service sector in Asia is critical to more balanced and sustainable growth of Asian economies. Whether enhancing connectivity in financial flows is as beneficial as trade connectivity is an important issue. Financial flows as well as direct investment have been significantly active within the region, contributing to interconnected Asian economies. Since the Asian financial crisis, Asian governments have promoted cross-border financial transactions through financial market deregulation and capital account liberalization. The measures for the extent of financial integration—quantity- and price-based measures—show significant progress in Asia's financial integration (Kim & Lee, 2012). Cross-border financial integration helps each country to be insured against country-specific income risks. It often contributes to the development of the domestic financial system and regional financial cooperation. In contrast to these general benefits, greater financial integration can also incur costs by increasing the sensitivity to external shocks and spillovers. Indeed, the Asian financial crisis in 1997–1998 and recent global crisis 2008–2009 exposed weaknesses in emerging Asia's financial sectors. The region's financial systems still remain inefficient, unable to maintain the pace of change and transformation occurring in real sector. Asian countries must pursue right policies to reap the benefits of financial integration. To strengthen the financial environment against the volatile external shocks, Asian economies need to improve financial sectors' weaknesses while developing more effective financial supervision and regulation and macroeconomic policy frameworks. An interesting question is whether Asian economies should push for greater regional trade interdependence, rather than globally, when larger global markets can bring larger welfare gains to trading partners. Brooks points out a number of cases supporting regional integration. For instance, it is pointed out that while geographical distance becomes less important for trade in goods and services, “comparative advantage of the region matters as much as that of the country when it comes to joining a global value chain.” The state of physical and ICT infrastructure is quite diverse across economies. The costs and benefits of intra-regional integration and specific cross-border infrastructure investment should be assessed accurately in order to design effective policies (for example, in terms of the area and sequencing of cross-border infrastructure investments) that can maximize the benefits of connectivity in the region.
