Foreign Investors Under Stress: Evidence from India
Description: Emerging market policy makers have been concerned about the financial stability implications of financial globalization. These concerns are focused on behavior under stressed conditions. Do tail events in the home country trigger off extreme responses by foreign investors – are foreign investors `fair weather friends'? In this, is there asymmetry between the response of foreign investors to very good versus very bad days? Do foreign investors have a major impact on domestic markets through large inflows or outflows – are they ‘big fish in a small pond’? Do extreme events in world markets induce extreme behavior by foreign investors, thus making them vectors of crisis transmission? We propose a modified event study methodology focused on tail events, which yields evidence on these questions. The results, for India, do not suggest that financial globalization has induced instability on the equity market.

Financial Structures and Economic Outcomes: An Empirical Analysis
Description: This paper investigates the potential relationships between financial structures and economic outcomes. The empirical results that withstand a battery of methods suggest that some financial intermediation structures are likely to be more closely related to positive economic outcomes than others. For instance, protective financial buffers within institutions have been associated with better economic performance, and a domestic financial system that is dominated by some types of nontraditional bank intermediation or that has a high proportion of foreign banks has in some cases been associated with adverse economic outcomes, especially during the financial crisis. The results also suggest that there may be trade-offs between beneficial effects on growth and stability of some financial structures. For example, the positive association of financial buffers with growth can diminish above a certain, relatively high, threshold—a too-safe system may limit the available funds for credit and hence growth.

Inclusive Growth and the Incidence of Fiscal Policy in Mauritius: Much Progress, But More Could be Done
Description: Using data from three household surveys, we review whether growth in Mauritius was inclusive and discuss the incidence of public expenditures and taxes. Generally, Mauritius enjoys an even income distribution and low rates of poverty. Nevertheless, over the 2000s, despite overall progress, the benefits of growth appear to have become more skewed. Employment income is the main contributor to inequality in Mauritius. Social protection expenditures reduce poverty and inequality, but could be better targeted, particularly for pensions. Income taxes are progressive, though given their small relative weight they have a negligible impact on income distribution. The VAT appears relatively progressive compared to other developing countries, although its impact on the overall distribution is also small. With better targeting of the sizable social spending, significant further progress in poverty alleviation could be achieved.

Near-Coincident Indicators of Systemic Stress
Description: The G-20 Data Gaps Initiative has called for the IMF to develop standard measures of tail risk, which we identify in this paper with systemic risk. To understand the conditions under which tail risk is present, it is first necessary to develop a measure of what constitutes a systemic stress, or tail, event. We develop such a measure and uses it to assess the performance of eleven near-term systemic risk indicators as ‘early’ warning of distress among top financial institutions in the United States and the euro area. Two indicators perform particularly well in both regions, and a couple of other simple indicators do well across a number of criteria. We also find that the sizes of institutions do not necessarily correspond with their contribution to spillover risk. Some practical guidance for policies is provided.

World Food Prices, the Terms of Trade-Real Exchange Rate Nexus, and Monetary Policy
Description: How should monetary policy respond to large fluctuations in world food prices? We study this question in an open economy model in which imported food has a larger weight in domestic consumption than abroad and international risk sharing can be imperfect. A key novelty is that the real exchange rate and the terms of trade can move in opposite directions in response to world food price shocks. This exacerbates the policy trade-off between stabilizing output prices vis a vis the real exchange rate, to an extent that depends on risk sharing and the price elasticity of exports. Under perfect risk sharing, targeting the headline CPI welfare-dominates targeting the PPI if the variance of food price shocks is not too small and the export price elasticity is realistically high. In such a case, however, targeting forecast CPI is a superior choice. With incomplete risk sharing, PPI targeting is clearly a winner.

External Liabilities and Crises
Description: We examine the determinants of external crises, focusing on the role of foreign liabilities and their composition. Using a variety of statistical tools and comprehensive data spanning 1970-2011, we find that the ratio of net foreign liabilities (NFL) to GDP is a significant crisis predictor, and the more so when it exceeds 50 percent in absolute terms and 20 percent of the country-specific historical mean. This is primarily due to net external debt--the effect of net equity liabilities is weaker and net FDI liabilities seem if anything an offset factor. We also find that: i) breaking down net external debt into its gross asset and liability counterparts does not add significant explanatory power to crisis prediction; ii) the current account is a powerful predictor, either measured unconditionally or as deviations from conventionally estimated “norms” iii) foreign exchange reserves reduce the likelihood of crisis more than other foreign asset holdings; iv) a parsimonious probit containing those and a handful of other variables has good predictive performance in- and out-of-sample. The latter result stems largely from our focus on external crises stricto sensu.

Energy Subsidies and Energy Consumption: A Cross-Country Analysis
Description: The economic and environmental implications of energy subsidies have received renewed attention from policymakers and economists in recent years. Nevertheless there remains significant uncertainty regarding the magnitude of the impact of energy subsidies on energy consumption. In this paper we analyze a panel of cross-country data to explore the responsiveness of energy consumption to changes in energy prices and the implications of our findings for the debate on energy subsidy reform. Our findings indicate a long-term price elasticity of energy demand between -0.3 and -0.5, which suggests that countries can reap significant long-term benefits from the reform of energy subsidies. Our findings also indicate that short-term gains from subsidy reform are likely to be much smaller, which suggests the need for either a gradual approach to subsidy reform or for more generous safety nets in the short term.

The Anatomy of the VAT
Description: This paper sets out some tools for understanding the performance of the value added tax (VAT). Applying a decomposition of VAT revenues (as a share of GDP) to the universe of VATs over the last twenty years, it emerges that developments have been driven much less by changes in standard rates than by changes in ‘C-efficiency’ (an indicator of the departure of the VAT from a perfectly enforced tax levied at a uniform rate on all consumption). Decomposing C-efficiency into a ‘policy gap’ (in turn divided into effects of rate differentiation and exemption) and a ‘compliance’ gap (reflecting imperfect implementation), results pieced together for EU members suggest that the former are in almost all cases far larger than the latter, with rate differentiation and exemptions playing roles that differ quite widely across countries.

The Welfare Implications of Services Liberalization in a Developing Country: Evidence from Tunisia
Description: We propose an integrated method based on a two-sector small open economy dynamic and stochastic general equilibrium model to estimate non-tariff barriers and quantify the impact of services liberalization. The major component of trade barriers is explicitly modeled through the introduction of entry-sunk costs. Hence, liberalization is treated assuming a government's policy decision aimed at reducing those costs. Then, we estimate the model using Bayesian techniques for Tunisia and the Euro Area. The paper presents a precise quantitative evaluation of services trade barriers as the difference between entry-sunk costs in Tunisia versus the Euro Area. We find significant welfare benefits in addition to aggregate and sectoral growth gains the Tunisian economy could attain following services liberalization. Surprisingly, the goods sector is the one that benefits the most from services liberalization in the short- and long-term horizons.

Export Quality in Developing Countries
Description: This paper develops new, far more extensive estimates of export quality, covering 178 countries and hundreds of products over 1962–2010. Quality upgrading is particularly rapid during the early stages of development, with quality convergence largely completed as a country reaches upper middle-income status. There is significant cross-country heterogeneity in quality growth rates. Within any given product line, quality converges both conditionally and unconditionally to the world frontier; increases in institutional quality and human capital are associated with faster quality upgrading. In turn, faster growth in quality is associated with more rapid output growth. The evidence suggests that quality upgrading is best encouraged through a broadly conducive domestic environment, rather than sector-specific policies. Diversification is important to create new upgrading opportunities.
