Forward and Spot Exchange Rates in a Multi-Currency World

Separate literatures study violations of uncovered interest parity (UIP) using regression-based and portfolio-based methods. We propose a decomposition of these violations into a cross-currency, a between-time-and-currency, and a cross-time component that allows us to analytically relate regression-based and portfolio-based facts, and to estimate the joint restrictions they place on models of currency returns. Subject to standard assumptions on investors’ information sets, we find that the forward premium puzzle (FPP) and the “dollar trade” anomaly are intimately linked: both are driven almost exclusively by the cross-time component. By contrast, the “carry trade” anomaly is driven largely by cross-sectional violations of UIP. The simplest model the data do not reject features a cross-sectional asymmetry that makes some currencies pay permanently higher expected returns than others, and larger time series variation in expected returns on the US dollar than on other currencies. Importantly, conventional estimates of the FPP are not directly informative about expected returns, because they do not correct for uncertainty about future mean interest rates. Once we correct for this uncertainty, we never reject the null that investors expect high-interest-rate currencies to depreciate, not appreciate.

Unveiling the Effects of Foreign Exchange Intervention: A Panel Approach

We study the effect of foreign exchange intervention on the exchange rate relying on an instrumental-variables panel approach. We find robust evidence that intervention affects the level of the exchange rate in an economically meaningful way. A purchase of foreign currency of 1 percentage point of GDP causes a depreciation of the nominal and real exchange rates in the ranges of [1.7-2.0] percent and [1.4-1.7] percent respectively. The effects are found to be quite persistent. The paper also explores possible asymmetric effects, and whether effectiveness depends on the depth of domestic financial markets.

Spillovers from China’s Growth Slowdown and Rebalancing to the ASEAN-5 Economies

After many years of rapid expansion, China’s growth is slowing to more sustainable levels and is rebalancing, with consumption becoming the main growth driver. This transition is likely to have negative effects on its trading partners in the near term. This paper studies the potential spillovers to the ASEAN-5 economies through trade, commodity prices, and financial markets. It finds that countries with closer trade linkages with China (Malaysia, Singapore, and Thailand) and net commodity exporters (Indonesia and Malaysia) would suffer the largest impact, with growth falling between 0.2 and 0.5 percentage points in response to a decline in China’s growth by 1 percentage point depending on the model used and the nature of the shock. The impact could be larger if China’s slowdown and rebalancing coincides with bouts of global financial volatility. There are also opportunities from China’s rebalancing, both in merchandise and services trade, and there is preliminary evidence that some ASEAN-5 economies are already benefiting from these trends.

The Level of Productivity in Traded and Non-Traded Sectors for a Large Panel of Countries

This paper explains in detail the construction of series for productivity in the traded and nontraded sectors for a panel of 56 countries spanning 1989–2012. The level of productivity in each sector is defined as real value added per worker in constant 2005 Purchasing Power Parity (PPP) U.S. dollars. To construct these series, we collect industry-level data from several sources, and classify individual industries as traded/non-traded using their ratio of exports to value added. Finally, we aggregate the industry data up to a traded sector and a non-traded sector, accordingly. This new dataset has two main advantages relative to existing datasets: (i) it defines more finely the traded/non-traded sectors, by drawing on much more disaggregated industry source data; and (ii) it allows for meaningful comparisons of the level of productivity across countries/sectors because sectoral productivity is adjusted by its own price level.

The Cost of Foreign Exchange Intervention: Concepts and Measurement

The accumulation of large foreign asset positions by many central banks through sustained foreign exchange (FX) intervention has raised questions about its associated fiscal costs. This paper clarifies conceptual issues regarding how to measure these costs both from an ex-post and an ex-ante (relevant for decision making) perspective, and estimates both marginal and total costs for 73 countries over the period 2002-13. We find ex-ante marginal costs for the median emerging market economy (EME) in the inter-quartile range of 2-5.5 percent per year; while ex-ante total costs (of sustaining FX positions) in the range of 0.2-0.7 percent of GDP per year for light interveners and 0.3-1.2 percent of GDP per year for heavy interveners. These estimates indicate that fiscal costs of sustained FX intervention (via expanding central bank balance sheets) are not negligible.

Inequality in China - Trends, Drivers and Policy Remedies

China has experienced rapid economic growth over the past two decades and is on the brink of eradicating poverty. However, income inequality increased sharply from the early 1980s and rendered China among the most unequal countries in the world. This trend has started to reverse as China has experienced a modest decline in inequality since 2008. This paper identifies various drivers behind these trends – including structural changes such as urbanization and aging and, more recently, policy initiatives to combat it. It finds that policies will need to play an important role in curbing inequality in the future, as projected structural trends will put further strain on equity considerations. In particular, fiscal policy reforms have the potential to enhance inclusiveness and equity, both on the tax and expenditure side.

Real Exchange Rate and External Balance: How Important are Price Deflators?

This paper contrasts real exchange rate (RER) measures based on different deflators (CPI, GDP deflator, and ULC) and discusses potential implications for the link—or lack thereof—between RER and external balance. We begin by documenting patterns in the evolution of different measures of RERs, and confirm that the choice of deflator plays a significant role in RER movements. A subsequent empirical investigation based on 35 developed and emerging market economies over 1995 to 2014 yields comprehensive and robust evidence that only the RER deflated by ULC exhibits contemporaneous patterns consistent with the expenditure-switching mechanism. We rationalize the empirical findings by introducing a simple model featuring nominal rigidity and trade in intermediate goods as the one in Obstfeld (2001) and Devereux and Engel (2007), which is shown to generate qualitatively identical patterns to empirical findings.

Quantifying the Spillovers from China Rebalancing Using a Multi-Sector Ricardian Trade Model

This paper assesses the spillovers from different facets of China rebalancing using a calibrated Ricardian trade model that includes 41 economies, each consisting of 34 sectors. We find that China’s move up the value chain in particular has the potential for significant spillovers – on the one hand, adversely affecting industrialized economies heavily involved in the Asia value chain, while at the same time generating positive spillovers to lower and middle income countries. The model’s strength lies in endogenously capturing production value chains and international trade of goods across sectors.
