This paper examines the macroeconomic implications of, and policy responses to surges in private capital inflows across a large group of emerging and advanced economies. In particular, we identify 109 episodes of large net private capital inflows to 52 countries over 1987-2007. Episodes of large capital inflows are often associated with real exchange rate appreciations and deteriorating current account balances. More importantly, such episodes tend to be accompanied by an acceleration of GDP growth, but afterwards growth has often dropped significantly. A comprehensive assessment of various policy responses to the large inflow episodes leads to three major conclusions. First, keeping public expenditure growth steady during episodes can help limit real currency appreciation and foster better growth outcomes in their aftermath. Second, resisting nominal exchange rate appreciation through sterilized intervention is likely to be ineffective when the influx of capital is persistent. Third, tightening capital controls has not in general been associated with better outcomes.

This paper shows that recent manifestations of sudden stops (SSs) in international capital flows have striking parallels in the early financial globalization era preceding World War I. All main capital-importing countries then faced episodic capital flow reversals averaging some 5 percent of GDP and with a median duration of four years. Most SSs also displayed striking crosscountry synchronization, being immediately preceded by rising world interest rates. Both fixed and floating exchange rate regimes were hit, with no significant differences between them. Yet, not all SSs resulted in currency drops: while some countries experienced currency collapses, others managed to preserve exchange rate stability. These different responses are related to domestic \"frictions\" that heightened the procyclicality of absorption and hindered precautionary reserve accumulation in some countries relative to others.

A stylized fact of the transition process is an early profound exchange rate depreciation followed by continuing real appreciation. Absent historical reference points, it is difficult to judge whether the real appreciation is threatening competitiveness. This paper interprets the stylized facts and offers estimates of the equilibrium real exchange rate based on an international comparison of dollar wages and on a study of the dynamics of real exchange rates in several transition economies. The results suggest that the process of real appreciation is a combination of a return to equilibrium following the early overshooting and equilibrium appreciation.

We study the effects of a credible, gradual exchange rate based disinflation program in a two sector economy. After an initial real exchange rate depreciation, the reductions in the rate of devaluation reduce the monetary wedge generated by a cash in advance constraint, leading to a gradual increase in absorption that yields progressive real exchange rate appreciations and current account deficits. An initial boom in economic activity is not followed by a later contraction, as labor supply expands during the whole length of the program.

This study examines the relationship between the foreign exchange regime and macroeconomic performance in Eastern Africa. The study focuses on seven countries, five of which decisively liberalized their foreign exchange regimes. The study assesses the relationship between (i) growth and various determinants, including the exchange regime, the real exchange rate, and current account liberalization; and (ii) inflation and various determinants, including lagged inflation, the nominal exchange rate, the exchange regime, and liberalization. We find that in our sample, for the determinants of growth, investment and the real exchange rate are significant determinants but not the exchange regime or liberalization; and for inflation, the lagged inflation rate, nominal exchange rate, and the de facto regime are significant. Exchange rate pass-through is limited.

A key issue in creating a new currency union is setting the rates to convert national currencies into the new union currency. Planned unions in the Gulf region and Africa are seeking methods to set the conversion rates when their new currencies are created. We propose a forward-looking econometric methodology to determine conversion rates by calculating the degree of misalignment in the real exchange rate, and apply it to the GCC currency union. For each GCC currency, we identify the year at which the economy is the closest to its internal and external equilibrium, and then estimate the degree of misalignment in the bilateral real exchange rate vis-à-vis the U.S. dollar based on WEO forecasts until 2013. Application of the methodology to other regions is also considered.

Using both regression- and VAR-based estimates, the paper finds that the exchange rate pass-through to import prices for a large number of countries is incomplete and larger than the pass-through to export prices. Previous studies have reported similar results, which give rise to the puzzle that while local currency pricing is needed to account for incomplete import price pass-through, it would not imply a lower export price pass-through. Recent explanations of this puzzle have emphasized markup adjustment in response to exchange rate changes. This paper suggests an alternative explanation based on the presence of both producer and local currency pricing. Using a dynamic general equilibrium model, the paper shows that a mix of producer and local currency pricing can explain the pass-through evidence even with a constant markup. The model can also explain the observed exchange rate and inflation variability as well as the fact that the regression and VAR estimates tend to be similar.
