1 Precautionary Demand for Foreign Assets in Sudden Stop Economies: An Assessment of the New Mercantilism Ceyhun Bora Durdu Enrique G. Mendoza Marco E. Terrones Board of Governors of the University of Maryland International Monetary Fund Federal Reserve & NBER The views presented in this paper are those of the authors and do not necessarily reflect the views of the Board of Governors of the Federal Reserve or the IMF.

2 Stylized facts & the New Mercantilism 1. Gradual financial globalization since late 1980s Sudden Stops since Mexico Foreign reserves have surged since Sudden Stops 8% of GDP in median SS country, 13% in Asia! New Mercantilism: a) Reserves are a war chest for defense against Sudden Stops b) Current account surpluses & undervalued currencies

3 Financial globalization in Sudden Stop countries (average of country indexes) Edwards right axis Chinn-Ito left axis

4 Surge in reserves in Sudden Stop Countries (difference of averages for SS year to 2005 minus 1985 to SS year) Country Year of Sudden Stop Change in reserves Hong Kong Korea Malaysia Thailand Uruguay Indonesia Philippines Russia Turkey Peru Pakistan Argentina II Argentina I Chile Brazil Colombia Mexico Ecuador Median 7.66 Median Asian Countries 13.17

5 Our analysis Is the New Mercantilism consistent with quantitative predictions of an optimal self-insurance framework? Three determinants of precautionary asset demand: 1. Business cycle volatility Increases in variability & persistence of output fluctuations 2. Financial globalization Lower tax on NFP or lower transactions costs 3. Endogenous Sudden Stop risk Credit constraints and liability dollarization trigger Fisherian deflation

6 Main findings 1. Volatility cannot explain surge in reserves because it has not increased post-globalization 2. Financial globalization and Sudden Stop risk produce surge in foreign assets Larger globalization effects at high financial integration Self insurance reduces sharply long-run prob. of Sudden Stops 3. Slow adjustment with protracted surpluses and undervalued real exchange rates 4. Implicit hedge in two-sector model lowers prec. savings 5. Results robust to specification of preferences

10 Strategy for the quantitative analysis 1. Calibrate 1S model to Mexican aggregate data 2. Use 1S model to examine effects of volatility and financial globalization 3. Calibrate 2S model to Mexican sectoral & agg. data 4. Revisit effects of volatility and financial globalization 5. Examine the effects of endogenous Sudden Stop risk

21 Conclusions New Mercantilism is only partially right: Volatility explanation fails Sudden Stop risk explains some of the surge in reserves but so does financial globalization even without Sudden Stops Slow transition after Sudden Stops or fin. globalization Persistent surpluses and undervalued exchange rates (not necessarily due to exchange rate management) Normative implications pose challenges Precautionary savings are suboptimal, but how suboptimal? and what feasible second-best arrangement can dominate? Financial globalization without financial development reduces welfare because of adverse distributional effects of prec. savings
