Real Exchange Rate and External Balance: How Important Are Price Deflators?
Description: 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.

World Trade in Services: Evidence from A New Dataset
Description: Using a newly constructed dataset on trade in services for 192 countries from 1970 to 2014, this paper shows that services currently constitute one-fourth of world trade and an increasingly important component of global production. A detailed analysis of patterns and stylized facts reveals that exports of services are not only gaining strong momentum and catching up with exports of goods in many countries, but they could also trigger a new wave of trade globalization. Research applications of the trade in service dataset on structural transformation, resilience, labor reallocation, and income distribution are outlined.

Inequality Overhang
Description: The linearity of the relationship between income inequality and economic development has been long questioned. While theory provides arguments for which the shape of relationship may be positive for low levels of inequality and negative for high ones, most of the empirical literature assumes a linear specification finding conflicting results. Employing an innovative empirical approach robust to endogeneity, we find pervasive evidence of nonlinearities. In particular, similar to the debt overhang literature, we identify an inequality overhang level in that the slope of the relationship between income inequality and economic development switches from positive to negative at a net Gini of about 27 percent. We also find that in an environment characterized by widespread financial inclusion and high income concentration, rising income inequality has a larger negative impact on economic development because banks may curtail credit to customers at the lower end of the income distribution. On the positive side, a sufficiently high female labor participation can act as a shock absorber reducing such negative impact, possibly through a more efficient allocation of resources.

Consumption in Brazil: Where to Next?
Description: Private consumption has been a key driver of growth in Brazil for more than a decade. Over this time, Brazilian consumers have benefited from a favorable policy environment, a rapid phase of development—dramatically increasing economic, financial and social inclusion— and a supportive external environment. Meanwhile, infrastructure gaps have widened and investment and productivity levels have fallen behind. The consumption-led growth model now appears to have run its course. The prospect of a period of macroeconomic adjustment presents an opportunity to adjust policy settings to ensure stronger, more balanced and sustainable growth over the medium term.

The Effects of Data Transparency Policy Reforms on Emerging Market Sovereign Bond Spreads
Description: We find that data transparency policy reforms, reflected in subscriptions to the IMF’s Data Standards Initiatives (SDDS and GDDS), reduce the spreads of emerging market sovereign bonds. To overcome endogeneity issues regarding a country’s decision to adopt such reforms, we first show that the reform decision is largely independent of its macroeconomic development. By using an event study, we find that subscriptions to the SDDS or GDDS leads to a 15 percent reduction in the spreads one year following such reforms. This finding is robust to various sensitivity tests, including careful consideration of the interdependence among the structural reforms.

Financial Stability Reports in Latin America and the Caribbean
Description: Many countries in Latin America and the Caribbean now publish financial stability reports. This study reviews their latest issues to assess their content, quality, and transparency. While some reports provide a strong analysis of risks and vulnerabilities, there are significant cross-country differences, and many reports could be improved by adopting a more comprehensive, forward-looking, and thematic assessment of financial stability. A well thought out communication strategy, including a regular and predictable publication schedule and an easily accessible website, is also important to enhance the impact of the reports. Data gaps, particularly at the disaggregated level, are material and need to be urgently addressed.

Excessive Private Sector Leverage and Its Drivers: Evidence from Advanced Economies
Description: Nonfinancial private sector debt increased significantly in advanced economies prior to the global financial crisis and, with a few exceptions, deleveraging has been limited. Furthermore, in some countries households and corporations have continued to accumulate debt. Drawing on the literature, the paper aims to provide a quantitative assessment of the gaps between actual and sustainable levels of debt and to identify the key factors that drive excessive borrowing. Results suggest that variables that are typically found important in studies focusing on borrowing decisions, are also relevant for explaining the debt sustainability gaps.

The Macroeconomics of De-Cashing
Description: The paper presents a simple framework for the analysis of the macroeconomic implications of de-cashing. Defined as replacing paper currency with convertible deposits, de-cashing would affect all key macroeconomic sectors. The overall macreconomic impact of de-cashing would depend on the balance of growth-enhancing and growth-constraining factors. Starting from a traditional saving-investment balance, the paper develops a four-sector macroeconomic framework. It is purely illustrative and is designed to provide a roadmap for a systematic evaluation of de-cashing. The framework is disaggregated into the real, fiscal, monetary, and external sectors and potential implications of de-cashing are then identified in each sector. Finally, the paper draws a balance on possible positive and negative macroeconomic implications of de-cashing, and proposes policies capable of augmenting its economic and social benefits, while reducing potential costs.

Foreign Exchange Intervention and the Dutch Disease
Description: We study the optimal foreign exchange (FX) intervention policy in response to a positive terms of trade shock and associated Dutch disease episode in a small open economy model. We find that during a Dutch disease episode tradable production drops below the socially optimal level, resulting in lower welfare under learningby- doing (LBD) externalities. FX reserves accumulation improves welfare by preventing a large appreciation of the real exchange rate and by inducing an efficient reallocation between the tradable and non-tradable sectors. For an empirically plausible parametrization of LBD externalities, the model predicts that in response to a 10 percent increase in commodity prices FX reserves should increase by 1.5 percent of GDP. We also find that the welfare gains from optimally using FX reserves are twice as high as the gains from relying only on monetary policy. These results suggest that FX intervention is a beneficial policy to counteract the loss of competitiveness during a Dutch disease episode.

Managing the Tide: How Do Emerging Markets Respond to Capital Flows?
Description: This paper examines whether—and how—emerging market economies (EMEs) respond to capital flows to mitigate their untoward consequences. Based on a sample of about 50 EMEs over 2005Q1–2013Q4, we find that EME policy makers respond proactively to capital inflows by using a combination of policy tools: central banks raise the policy interest rate to address economic overheating concerns; intervene in the foreign exchange market to resist currency appreciation pressures; tighten macroprudential measures to dampen credit growth; and deploy capital inflow controls in the face of competitiveness and financial-stability concerns. Contrary to conventional policy advice to EMEs, we find no evidence of counter-cyclical fiscal policy in the face of capital inflows. Overall, policies are more likely to respond, and used in combination, during inflow surges than in more normal times.
