International Trade and Finance…and Policy

I’ve just returned from two highly stimulating conferences in Beijing. The first was a Columbia-Tsinghua conference on “Capital Flows and International Financial Systems”, organized by Jiandong Ju and Shang-Jin Wei, and the second a NBER-China Center for Economic Research conference on “China and the World Economy”, organized by Yang Yao, Shang-Jin Wei, and Chong-En Bai.

The RMB Exchange Rate, Capital Market Openness, and Financial Reforms in China

A policy panel at the Columbia-Tsinghua conference was chaired by Chaired by Shang-Jin Wei (Chief Economist Designate, Asian Development Bank, Professor of Economics at Columbia University, and NBER). The participants were:


  • Joshua Aizenman (Professor of Economics and International Relations, University of Southern California and the NBER)
  • Menzie Chinn (Professor of Public Affairs and Economics, University of Wisconsin, Madison, and NBER)
  • Pierre-Olivier Gourinchas (Professor of Economics, University of California Berkeley and NBER)
  • Fan He (Professor and Associate Dean, The Institute of International Economics and Politics, The Chinese Academy of Social Science)
  • Jiandong Ju (Professor and Director, Center for International Economic Research at Tsinghua University)
  • Jun Ma (Chief Economist, Research Department, People’s Bank of China; former Chief Economist for Greater China, Deutsche Bank)

The presentations were not made available online, and I can’t do justice to all the presentations. However, one surprising aspect of the discussion was the widespread agreement that capital account liberalization was an undertaking that needed to be conducted very slowly and deliberately. Aizenman (presentation), Gourinchas and He highlighted the potential for financial or balance of payments crises should capital account and domestic financial liberalization be improperly sequenced. Gourinchas further noted that the benefits of capital account openness were uncertain, and apparently relatively small, so the urgency for liberalization was not so great. (Update: Gourinchas’s points here.)

Both He and Ma noted that capital account liberalization had already progressed to a certain extent, with Ma making the case more forcefully. Ju argued that premature liberalization of the capital account could lead to capital flight and and domestic financial crisis as the housing market collapsed. Some discussion of the Ma, He, and Ju presentations are reported in the People’s Daily.

The major point of my presentation was that development of the RMB as an international currency was not costless, despite the pride that might be engendered by such a outcome. In particular, an internationalized currency exposes an economy to external shocks, and some loss of monetary autonomy if other countries peg to it. Such already seems to be the case for China. Some of these points are discussed in this paper.

International Economics (Columbia-Tsinghua)

I couldn’t attend all the sessions at the Columbia-Tsinghua conference (there were at times parallel sessions), but here are some of the papers I caught.

Jing Zhang (FRB Chicago) presented “Saving Europe?: The Unpleasant Arithmetic of Fiscal Austerity in Integrated Economies” (with E. Mendoza and L. Tesar).

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore crosscountry spillovers of tax changes. Instead, we examine this issue using a two-country model that matches the observed elasticity of the capital tax base by introducing endogenous capacity utilization and a partial depreciation allowance. Tax hikes have adverse effects on macro aggregates and welfare, and trigger strong cross-country externalities. Quantitative analysis calibrated to European data shows that unilateral capital tax increases cannot restore fiscal solvency, because the dynamic Laffer curve peaks below the required revenue increase. Unilateral labor tax hikes can do it, but have negative output and welfare effects at home and raise welfare and output abroad. Large spillovers also imply that unilateral capital tax hikes are much less costly under autarky than under free trade. Allowing for one-shot Nash tax competition, the model predicts a “race to the bottom” in capital taxes and higher labor taxes. The cooperative equilibrium is preferable, but capital (labor) taxes are still lower (higher) than initially. Moreover, autarky can produce higher welfare than both Nash and Cooperative equilibria.

Yinqiu Lu (IMF) presented “Emerging Market Local Currency Bond Yields and Foreign Holdings in the Post-Lehman Period – a Fortune or Misfortune?” (with C. Ebeke):

The paper shows that foreign holdings of local currency government bonds in emerging
market countries (EMs) have reduced bond yields but have somewhat increased yield volatility in the post-Lehman period. Econometric analyses conducted from a sample of 12 EMs demonstrate that these results are robust and causal. We use an identification strategy exploiting the geography-based measure of EMs financial remoteness vis-à-vis major offshore financial centers as an instrumental variable for the foreign holdings variable.The results also show that, in countries with weak fiscal and external positions, foreign holdings are greatly associated with increased yield volatility. A case study using Poland data elaborates on the cross country findings.

Likun Wang (Goethe University Frankfurt) presented “Exchange rate, risk premium and factors: what can term structure of interest rates tell us about the dynamics of the exchange rate?”:

In this paper, I investigate the role of expectations on the current and future status of economies in determining the dynamics of the exchange rate, through the channel of risk premium for holding a currency. The risk premium is introduced as an additional term to a best-fit time series model and is instrumented by bilateral latent factors obtained from the term structure of interest rates. Results show that it can significantly improve the baseline model in terms of in-sample goodness of fit and out-of-sample accuracy of forecast in exchange rate changes. The non-linearity of the risk premium in latent factors further renders state-dependent and time-varying response of change in exchange rate to an identified monetary policy adjustment. Above findings hold for seven out of eight advanced-economy currency pairs (AUD, CAD, GBP, JPY, NOK, NZD, SEK against USD). Once included in the Fama regression, the risk premium can also help in solving the UIP Puzzle, which has been detected in the cases of GBP/USD and JPY/USD.

Other presentations (w/o papers online):

    What is interesting is that when China returns to the gold standard probably 90% of the discussion will be moot.

    Menzie wrote,”…development of the RMB as an international currency was not costless, despite the pride that might be engendered by such a outcome. In particular, an internationalized currency exposes an economy to external shocks, and some loss of monetary autonomy if other countries peg to it.” On a gold standard a currency is highly insulated from external monetary shocks and other countries will lose their monetary autonomy as they peg to the RMB and by extension gold.

    While floating currencies employ a lot of economists and government analysts, a gold standard will free these people up to do actual productive work.

    That of course is why there were no international financial crises in the 19th century.

    Isn’t faith wonderful.

  3. Ricardo

    Spener,

    That is why the economic growth of the 19th Centruy was over 4%. As long as you have governments meddling in the economy you will have financial crises.

      Are you joking? I can no longer tell if you’re serious or joking or simply typing nonsense because your meds aren’t working. The Fed was created because the unregulated US economy and banking system had so many financial panics, as in the Panic of 1893 was followed by the Panic of 1907. This is basic US history.

  4. Ricardo

    Menzie,

    I do appreciate your attention to China. Your posts on China have been very instructive and this one is not exception. It is interesting that the only place in the world where there is a serious debate between demand side economics and supply side economics is in China. On that it is interesting that this article by Steve Hanke was printed in the South China Morning Post..

    An aside: Professor Hamilton I would really appreciate your analysis and contrast of the new GO vs GDP discussion. Many supply side economists and business experts are praising the GO as a step in the right direction. I am still inthe non-commital stage.

    China leaning toward a gold rmb.

    Most links to a gold backed rmb are just gold dealers trying to get people to buy their products. In truth if China did link the rmb to gold it is highly doubtful that the price of gold would change significantly. All that would happen is that the rmb would be used more in transactions because it would be the most stable currency in the world. There would be no reason to carry gold if the rmb was as good as gold.
