South Africa’s Exports Performance: Any Role for Structural Factors?
Description: Despite a substantial and prolonged exchange rate depreciation, South Africa’s export performance has disappointed since the global financial crisis. In this paper we focus on the role of structural factors in reducing the responsiveness of South African exports to the real exchange rate depreciation. To this end, we construct a unique database of export performance at the firm level. Our analysis suggests that electricity bottlenecks, limited product market competition, and labor market constraints have reduced the responsiveness of firms’ exports to the rand depreciation. On the other hand, a firm’s ability to diversify its exports has helped it benefit more from currency movements.

An Empirical Investigation of Oil-Macro-Financial Linkages in Saudi Arabia
Description: Oil-macro-financial linkages in Saudi Arabia are analyzed by applying panel econometric frameworks (multivariate and vector autoregression) to maceoeconomic and bank-level balance sheet data for 9 banks spanning 1999–2014. Lower growth of oil prices and non-oil private sector output leads to slower credit and deposit growth and higher nonperforming loan ratios, with feedback loops within bank balance sheets which in turn dampens economic activity. U.S. interest rates are not found to be a key determinant.

Trends in Gender Equality and Women’s Advancement
Description: This paper examines trends in indicators of gender equality and women’s development, using evidence derived from individual indicators and gender equality indices. We extend both the United Nations Development Program’s Gender Development Index and Gender Inequality Index to examine time trends. In recent decades, the world has moved closer to gender equality and narrowed gaps in education, health, and economic and political opportunity; however, substantial differences remain, especially in South Asia, the Middle East, and sub-Saharan Africa. The results suggest countries can make meaningful improvements in gender equality, even while significant income differences between countries remain.

Wage-Price Dynamics and Structural Reforms in Japan
Description: Structural reforms in the liquidity trap need not be deflationary. This paper develops a simple framework to study the role that key characteristics of Japan’s labor and product markets—labor-market duality and weak corporate governance—play in generating unfavorable wage-price dynamics. The model allows a discussion of whether and in what form structural reforms may contribute to Japan’s short-run goal of reflating the economy. It finds that boosting inflation with structural reforms implies an unusual trade-off with employment, that is an inverted Phillips curve. Simultaneous implementation of labor-market and product-market reforms is most effective in terms of reflating the economy.

Robust Measures of Core Inflation for Vietnam
Description: The paper develops robust measures of core inflation for Vietnam that can be used in policy making. These core inflation measures (CIMs) are based on an analytical evaluation of the inflation process in Vietnam, and use a filtering approach to narrow down potential measures that satisfy certain empirically desirable criteria. The paper finds that commonly used exclusion-based measures (EBMs) do not perform well against these empirical criteria; trimmed mean measures (TMMs) do better. Among TMMs, “one trim does not fit all periods”; periods of high and variable inflation require larger trims, and conversely. EVIEWS and MATLAB programs which accompany the paper allow quick, timely replication of CIMs as new data become available, making them valuable tools for the State Bank of Vietnam on an ongoing basis.

From Global Savings Glut to Financing Infrastructure: The Advent of Investment Platforms
Description: This paper investigates the emerging global landscape for public-private co-investments in infrastructure. The creation of the Asian Infrastructure Investment Bank and other so-called “infrastructure investment platforms” are an attempt to tap into the pool of both public and private long-term savings in order to channel the latter into much needed infrastructure projects. This paper puts these new initiatives into perspective by critically reviewing the literature and experience with public private partnerships in infrastructure. It concludes by identifying the main challenges policy makers and other actors will need to confront going forward and to turn infrastructure into an asset class of its own.

Unintended Consequences: Spillovers from Nigeria’s Fuel Pricing Policies to Its Neighbor
Description: This paper examines the constraints that negative externalities (i.e., smuggling from a large neighbor) impose on the application of automatic fuel price adjustment mechanisms. It is often recommended to establish an automatic price adjustment mechanism to reduce fuel subsidy expenditures, but this approach may not work in the presence of these externalities. The paper illustrates the constraints by examining the case of Nigeria, a major oil exporter that subsidizes gasoline, and that of Togo, an oil importer and neighbor of Nigeria. It finds that the price differential between formal prices in Togo and Nigeria is the main driver of changes in formal sector gasoline consumption. Specifically, the lower the formal price in Nigeria, the higher is smuggling from Nigeria to Togo, and the lower the tax base in Togo. The econometric results suggest that, unless the real economy is performing very well, increases in pump prices in Togo are likely to erode the tax base, unless there are greater border controls. The unintended consequences of Nigeria’s pricing policies are the constraint they impose on fuel pricing policies of its neighbors and the subsidy Nigeria transfers to them (equivalent to at least 3 percent of Togo’s GDP in 2011), three-quarters of which was captured by smugglers in 2011, while one-quarter enhanced consumers surplus through lower gasoline prices.

Macroeconomic Impacts of Gender Inequality and Informality in India
Description: This paper examines the macroeconomic interaction between informality and gender inequality in the labor market. A dynamic stochastic general equilibrium model is built to study the impact of gender-targeted policies on female labor force participation, female formal employment, gender wage gap, as well as on aggregate economic outcomes. The model is estimated using Bayesian techniques and Indian data. Although these policies are found to increase female labor force participation and output, lack of sufficient formal job creation due to labor market rigidities leads to an increase in unemployment and informality, and further widens gender gaps in formal employment and wages. Simultaneously implementing such policies with formal job creating policies helps remove these adverse impacts while also leading to significantly larger gains in output.

Structural Reforms and Productivity Growth in Emerging Market and Developing Economies
Description: This paper empirically assesses the role of structural and institutional reforms in driving productivity growth across countries at different stages of development, using a distance-to-frontier framework. It gauges whether particular policies and reforms matter more for increasing productivity growth at the aggregate and sectoral levels for some emerging market and developing economies (EMDEs) than others. Recognizing the possibility of time lags between reform implementation and reform payoffs, the paper also examines how productivity gains from various reforms evolve over the the short- and medium-term.

The Fiscal Costs of Contingent Liabilities: A New Dataset
Description: We construct the first comprehensive dataset of contingent liability realizations in advanced and emerging markets for the period 1990–2014. We find that contingent liability realizations are a major source of fiscal distress. The average fiscal cost of a contingent liability realization is 6 percent of GDP but costs can be as high as 40 percent for major financial sector bailouts. Contingent liability realizations are correlated among each other and tend to occur during periods of growth reversals and crises, accentuating pressure on the budget during already difficult times. Countries with stronger institutions are able to better control and address the underlying risks so that they are less exposed to contingent liability realizations.
