Guest Contribution: East Asian Production Networks, Global Imbalances, and Exchange Rate Coordination

By Willem Thorbecke

Today, we’re fortunate to have Willem Thorbecke, Senior Research Fellow at Asian Development Bank Institute and a Consulting Fellow at Japan’s Research Institute of Economy, Trade and Industry, as a guest contributor.

Asia’s role in the propagation of the global recession has been a subject of study, but relatively little attention has been devoted to the interaction of exchange rates and production chains. The structure of East Asian production networks and the severity of the recession places a premium on policy coordination in the region.

Multinational corporations in East Asia have established value chains by slicing up production processes and allocating the production blocks across countries in the region based on relative endowments of capital, skill, labor, and infrastructure. As MNCs increase their tenure in developing Asia, they procure more from local firms. This leads to the formation of industrial clusters, and local engineers and skilled workers begin migrating among firms and sectors. They bring their accumulated human capital with them and disperse it across the economy, promoting technological assimilation and productivity growth.
For instance, Kraemer and Dedrick document that the lion’s share of the international production of notebook PCs is produced in the Yangtze River Delta by Taiwanese Original Design Manufacturers (ODMs). These manufacturers form part of a network that includes branded firms such as HP, Apple, and Toshiba, suppliers of key parts and components, producers of basic industrial materials, and makers of operating systems and CPU. Local Chinese firms supply connectors, batteries, switches, and displays and are also active in molding, casting, forging, plating, and module-assembling. Both digital and human networks enable PC producers to react efficiently in real time to changes in consumer preferences and technology. Firms assembling the notebook PCs have also kept inventories lean by processing 98 percent of the orders within three days. Productivity growth within this value chain has been amazing.

The Achilles heel of Asian production networks, though, is its dependence on developed economies for final demand. As private demand in the U.S., Europe, and Japan fell during the crisis, exports produced within regional production networks collapsed. This in turn caused output and employment throughout Asia to plummet.
Signs are emerging that East Asian production networks are reviving. Figure 1 shows imports for processing into China and processed exports from China to the rest of the world. Imports for processing are goods that are brought into China for processing and re-export. Processed exports are final goods that are produced using imports for processing. The figure shows that imports for processing and processed exports both collapsed earlier this year. Since then, however, imports for processing have recovered 85 percent of their losses and processed exports 75 percent. Thus trade within East Asian production networks is recovering. This is the good news coming out of Asia.

The not so good news is that exchange rate arrangements within the region may not allow this revival to be sustained. While many Asian countries have adopted greater exchange rate flexibility, China has returned to a de facto dollar peg. This implies that exchange rates between Asian countries have become very volatile (see, e.g., Figure 2). In general the effect of exchange rate volatility on trade is ambiguous. Within East Asian production networks, however, both theoretical and empirical evidence indicates that exchange rate volatility deters trade (see Thorbecke (2008) and Hiyakawa and Kimura (2009)). This effect arises because the service link cost for production blocks separated by national borders is an increasing function of risk and uncertainty, and exchange rate volatility increases risk and uncertainty. In a recent survey of Japanese MNCs, Professor Takatoshi Ito and his co-authors found that exchange rate stability between Asian currencies is essential for the uninterrupted flow of parts and components within regional production networks.

In addition, since Asian economies do not only cooperate within production networks but also compete in third markets, China’s exchange rate peg puts pressure on other countries in the region to prevent their exchange rates from appreciating. Thorbecke and Smith (2009) reported that exchange rate appreciations across Asian supply chain countries are necessary to reduce global imbalances. If the renminbi is kept fixed, it becomes much harder for the huge surpluses generated within East Asian production networks to lead to a generalized appreciation of Asian currencies.

A solution to this impasse would be for China to abandon its de facto dollar peg and adopt a regime characterized by a multiple-currency, basket-based reference rate with a reasonably wide band. In this case, there would be more stability between the renminbi and other Asian currencies. In addition, exchange rates in the region would be able to appreciate together in response to regional trade surpluses.
This move would be difficult for China. Labor-intensive exports and thus employment in these industries are sensitive to exchange rate appreciations. On the other hand, exchange rate appreciations would reduce the need for Chinese and other Asian central banks to continue accumulating U.S. Treasury securities. Private and social rates of return are much higher for investments in education, healthcare, and clean water than for investments in U.S. government securities. An appreciation of the RMB would also allow Chinese consumers to purchase more of the final manufactured goods that were previously exported to developed markets (Thorbecke, 2009). A stronger renminbi would thus allow Chinese workers to enjoy more of the fruits of their labor while reducing their dependence on final demand in the West.

A good policy mix for Asia would thus involve relatively stable intra-regional exchange rates that could appreciate together in response to regional trade surpluses combined with more spending on human capital. Stable exchange rates would help to strengthen regional production networks. Joint appreciations would prevent unpleasant outcomes such as beggar-thy-neighbor policies and excessive reserve accumulation while also reducing global imbalances and encouraging production for domestic markets. Spending on human capital would facilitate technology transfer by allowing firms in developing Asia to become more involved in the engineering and design aspects of production. If Asian countries could climb the value chain in this way and focus on knowledge-intensive activities rather than assembly operations, not only would living standards in developing Asia rise but the region could become an engine of growth for the rest of the world.

    Nice try. Good luck if you can convince China that in these times of deficient aggregate demand, it would be in their own self interest to stop currency interventions. It would surely be in the U.S. interest, as Krugman just recently noted. But I doubt if it would do anything for China but reduce its economic growth.

    It is amazing to me that someone can give us such great analysis of the relationship of Asian currencies to one another then totally miss this same relationship to the world economy. Robert Mundell has stated many times that the only closed economy is the world economy. Here Thorbecke attempts to have us believe that Asia is a closed economy.
    Currency stabilization for Asia is very important for the health of the region, but the same condition relates to stabilization of these currencies with the dollar. China understands that to normalize trade with the US the RMB and the dollar must have a stable relationship such that neither the US nor China experiences a windfall profit or loss from currency fluctuations.
    I am still trying to understand how Thorbecke can reject the money illusion when it comes to Asian currencies but then embrace it when it comes to major trading partners such as China and the US. I can understand US economists making such foolish statements because they are attempting to con China into windfall currency losses against the dollar but Thorbecke seems to be more aligned with the Asian currencies and therefore should not promote windfall currency losses for Asia.
    Very curious indeed.

    “Private and social rates of return are much higher for investments in education, healthcare, and clean water than for investments in U.S. government securities.”
    The idea that there is a trade off of funding domestic projects versus buying Treasuries, is based on the assumption that the Chinese sell $1B worth of internal sterilization bonds for each $1B of Treasuries they buy. But is there any evidence that that is what happens?
    Are there $800B in sterilization bonds?
    Especially now, when China’s money supply is growing at something like 28%/year, doesn’t it seem likely that they are most likely NOT sterilizing their Treasury purchases?

    The question is why Chinese economists are so obsessed with the export economy at the detriment of domestic consumption. Domestic consumption can drive GDP growth and employment just as well as exports and it would seem logical that improvements in the standard of living would be good for the Communist Party. So why are they so resistant to this path?

  5. RicardoZ

    Why should the Chinese government worry about either? Can you separate Walmart sales from Walmart imports? Can you separate Chinese wages from the products they sell to the US?
    This is one of the most serious problems with government on a command economy. They believe that they can dictate the citizen’s life-style.
    If the Chinese want more domestic consumption then the Chinese government has to allow more domestic freedom. They cannot create more domestic consumption if it goes against what the people consider as their best interest.
    One problem econometricians have is forgetting that people actually make decisions based on what is in their best interest not based on a static equation.

    Joseph -
    My guess is that they realize they would have a bigger shortfall in aggregate demand (and attendant higher unemployment and reduced real output) if they gave up currency intervention in favor of relying more heavily on domestic demand. The same reason countries competed with devaluations in GD1.

  7. GK

    The thing is, the rest of the world is just not big enough for China to remain an export-driven economy like Taiwan. A trade surplus of 2% of GDP is just not something the rest of the world can sustain for China.
    Also, as Ricardo said, more consumption is inseparable from more freedom, particularly after the basic necessities are met.
    Pretty soon, China’s economic growth will downshift to a still-impressive 6% a year. But 10% can’t last much past 2015 or so.

  8. Hal Horvathhalb

    Joseph, great question. don, GK and others, good comments.
    One point is of course that China cannot suddenly increase it’s domestic consumption, but…it can indeed make both long-term and short-term changes and programs to gradually increase domestic consumption. For instance one key insight has to do with *exactly why Chinese consumers save so much*, and how that could change, and precisely what is needed:

    I don’t understand this conviction that the only path to RMB/dollar equilibrium is RMB appreciation. Even if one buys the premise that RBM is undervalued currently, RBM can get to equilibrium through Higher inflation. Right? By the way, does anyone know the price of a single shot starbucks espresso in Shanghai?
    Take a wild guess?
    I was also told that if one wants to add sugar or milk, each would be 3RMB extra.
    I think the real exchange rate of RMB is appreciating. And American’s export to China is undercounted — I know many Chinese who bring more luggage to China than back to the US in their visits to China in the past couple of years. I am also curious whether the tuitions and living expenses paid by many these Chinese students studying in the US universities are counted as US exports?

  10. pat

    Also, letting the real exchange rate drift to equilibrium through a bit faster inflation may be more acceptable to Chinese officials because in this way, the loss to their dollar reserve will not be explicit.
    Higher inflation may not be politically costly as long as it keeps the recent pattern: not much in stables, but much higher in “non essential” stuff, such education, healthcare, etc. In particular, housing cost has gone through the roof, but people complain little as they seem all consider the money spent buying an apartment investment only, not part of the living cost as well.
