What Measure of Inflation Should a Developing Country Central Bank Target?
Description: In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained and the share of food expenditures in total consumption expenditures is high. We develop an open economy model with incomplete financial markets to show that headline inflation targeting improves welfare outcomes. We also compute the optimal price index, which includes a positive weight on food prices but, unlike headline inflation, assigns zero weight to import prices.

Building a Better Union: Incentivizing Structural Reforms in the Euro Area
Description: The momentum for structural reforms is waning in the euro area at a time when even faster progress is needed to boost productivity and growth, achieve real economic convergence, and improve the resilience of the monetary union. What can the European Union (EU) institutions do to bridge this divide? This paper argues for greater simplicity, transparency and accountability in the EU governance framework for structural reforms. Our three interrelated proposals—“outcome-based” benchmarking; better use of existing EU processes to strengthen oversight and reduce discretion; and improved financial incentives—could help advance reforms. Ex post monitoring by an independent EU-level “structural council” and ex ante policy innovation by national productivity councils could strengthen accountability and ownership. Deeper governance reforms should be considered in the medium-term with a view toward a greater EU role in promoting convergence.

“But we are different!”: 12 Common Weaknesses in Banking Laws, and What to Do About Them
Description: Well-designed banking laws are critical for regulating the market access and operations of banks, as well as their removal from the market in case of failure. While at a financial policy level there is a broad consensus as to the content of banking laws, from a legal perspective their drafting often leaves something to be desired. In spite of what is often argued, the types of weaknesses of banking laws are hardly country-specific; many weaknesses are shared by many banking laws. This working paper discusses those weaknesses and ways to remedy them, by focusing on a selected set of legal policy principles.

Demand for Value Added and Value-Added Exchange Rates
Description: We examine the role of cross-border input linkages in governing how international relative price changes influence demand for domestic value added. We define a novel value-added real effective exchange rate (REER), which aggregates bilateral value-added price changes, and link this REER to demand for value added. Input linkages enable countries to gain competitiveness following depreciations by supply chain partners, and hence counterbalance beggar-thy-neighbor effects. Cross-country differences in input linkages also imply that the elasticity of demand for value added is country specific. Using global input-output data, we demonstrate these conceptual insights are quantitatively important and compute historical value-added REERs.

Delegated Portfolio Management, Benchmarking, and the Effects on Financial Markets
Description: We analyze the implications of linking the compensation of fund managers to the return of their portfolio relative to that of a benchmark—a common solution to the agency problem in delegated portfolio management. In the presence of such relativeperformance- based objectives, investors have reduced expected utility but markets are typically more informative and deeper. Furthermore, in a multiple asset/market framework we show that (i) relative performance concerns lead to an increase in the correlation between markets (financial contagion); (ii) benchmark inclusion increases price volatility; (iii) home bias emerges as a rational outcome. When information is costly, information acquisition is hindered and this attenuates the effects on informativeness and depth of the market.

Is There a Debt-threshold Effect on Output Growth?
Description: This paper studies the long-run impact of public debt expansion on economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. Our contribution is both theoretical and empirical. On the theoretical side, we develop tests for threshold effects in the context of dynamic heterogeneous panel data models with cross-sectionally dependent errors and illustrate, by means of Monte Carlo experiments, that they perform well in small samples. On the empirical side, using data on a sample of 40 countries (grouped into advanced and developing) over the 1965- 2010 period, we find no evidence for a universally applicable threshold effect in the relationship between public debt and economic growth, once we account for the impact of global factors and their spillover effects. Regardless of the threshold, however, we find significant negative long-run effects of public debt build-up on output growth. Provided that public debt is on a downward trajectory, a country with a high level of debt can grow just as fast as its peers in the long run.

Aid and Growth at the Regional Level
Description: This paper brings the aid effectiveness debate to the sub-national level. We hypothesize the nonrobust results regarding the effects of aid on development in the previous literature to arise due to the effects of aid being insufficiently large to measurably affect aggregate outcomes. Using geocoded data for World Bank aid to a maximum of 2,221 first-level administrative regions (ADM1) and 54,167 second-level administrative regions (ADM2) in 130 countries over the 2000-2011 period, we test whether aid affects development, measured as nighttime light growth. Our preferred identification strategy exploits variation arising from interacting a variable that indicates whether or not a country has passed the threshold for receiving IDA's concessional aid with a recipient region's probability to receive aid, in a sample of 478 ADM1 regions and almost 8,400 ADM2 regions from 21 countries. Controlling for the levels of the interacted variables, the interaction provides a powerful and excludable instrument. Overall, we find significant correlations between aid and growth in ADM2 regions, but no causal effects.

A New Look at the Determinants of Growth in Asian Countries
Description: This study examines the drivers of growth in Asian countries, with focus on the role of investment, the exchange rate regime, financial risk, and capital account openness. We use a panel data set of a sample of Asian countries over the period 1980 to 2012. Our results indicate that private and public investments are strong drivers of growth, while more limited evidence is found that reduced financial risk and higher foreign direct investment support growth. The exchange rate regime does not appear to be a strongly significant determinant of growth, but some specifications suggest that more flexible regimes are beneficial in this respect. Financial crises have a stronger dampening effect on growth in countries with more open capital accounts.

Normalization of Global Financial Conditions: The Implications for Brazil
Description: Global financial conditions are poised to tighten further as the global recovery proceeds. While monetary policy normalization should be a healthy global development as growth continues to recover in advanced economies, financial spillovers seen during the taper episode—which started with the announcement in May 2013 of possible tapering of U.S. asset purchases—hint at potential challenges for Brazil. The Fed’s communications related to normalization have improved significantly since the taper episode and, at present, a rise in Fed Funds rate in 2015 is widely anticipated by markets—arguably the most widely anticipated tightening of monetary policy in history. While Brazil could benefit from tighter global financial conditions associated with improved global prospects, bouts of heightened uncertainty about the future course of monetary policy cannot be ruled out. Thus, the correct diagnosis of the underlying reasons behind tighter global financial conditions remains crucially important for Brazil. Adverse spillovers can be mitigated by strengthening policy frameworks and fundamentals.

Capital Inflows, Credit Growth, and Financial Systems
Description: Exploiting a granular panel dataset that breaks down capital inflows into FDI, portfolio and other categories, and distinguishes between credit to the household sector and to the corporate sector, we investigate the association between capital inflows and credit growth. We find that non-FDI capital inflows boost credit growth and increase the likelihood of credit booms in both household and corporate sectors. For household credit growth, the composition of capital inflows appears to be more important than financial system characteristics. In contrast, for corporate credit growth, both the composition and the financial system matter. Regardless of sectors and financial systems, net other inflows are always linked to rapid credit growth. Firm-level data corroborate these findings and hint at a causal link: net other inflows are related to more rapid credit growth for firms that rely more heavily on external financing. Further explorations on how capital flows translate into more credit indicate that both demand and supply side factors play a role.
