Resource Dependence and Fiscal Effort in Sub-Saharan Africa
Description: High natural resource prices in recent years have resulted in sizeable increases in fiscal revenue for many resource-exporting countries in sub-Saharan Africa. However, this revenue source is volatile, and arguably these countries should also rely on other forms of taxation to help fund public expenditure. This paper asks whether the availability of higher resource revenue in these countries has led to lower taxation effort of other revenue categories. The question is analyzed both in terms of the relationship between non-resource tax revenue and resource revenue, and between non-resource tax revenue and statutory tax rates. The paper finds evidence suggesting that nonresource revenue is negatively influenced by a higher resource revenue-to-GDP ratio. The lower take up of nonresource taxes in resource-rich countries is correlated with higher levels of corruption in these countries, suggesting weaker institutions affect nonresource revenue through incentives for tax evasion and/or large tax exemptions as argued in the literature.

Waste Not, Want Not: The Efficiency of Health Expenditure in Emerging and Developing Economies
Description: Public health spending is low in emerging and developing economies relative to advanced economies and health outputs and outcomes need to be substantially improved. Simply increasing public expenditure in the health sector, however, may not significantly affect health outcomes if the efficiency of this spending is low. This paper quantifies the inefficiency of public health expenditure and the associated potential gains for emerging and developing economies using a stochastic frontier model that controls for the socioeconomic determinants of health, and provides country-specific estimates. The results suggest that African economies have the lowest efficiency. At current spending levels, they could boost life expectancy up to about five years if they followed best practices.

Collateral and Monetary Policy
Description: Financial lubrication in markets is indifferent to margin posting via money or collateral; the relative price(s) of money and collateral matter. Some central banks are now a major player in the collateral markets. Analogous to a coiled spring, the larger the quantitative easing (QE) efforts, the longer the central banks will impact the collateral market and associated repo rate. This may have monetary policy and financial stability implications since the repo rates map the financial landscape that straddles the bank/nonbank nexus.

Two Sides of the Same Coin? Rebalancing and Inclusive Growth in China
Description: This paper uses the Shapley Value decomposition technique to assess the factors behind the rise of inequality in China. It finds that, in many ways, inequality may have been an inevitable by-product of China’s investment and export-led growth model. Between Chinese households, we find that the most important factors explaining income inequality are location, education, access to health insurance, and labor market variables, including the sector of employment and enterprise size. Across China’s provinces, divergences in per capita incomes are driven by the relative level of capital-intensity, public spending, financial access, privatization, and urbanization. In addition, excess liquidity may have exacerbated inequality in the last decade, by driving up property prices and the wealth gap. Based on these results, policies that could help broaden the benefits of growth in China include maintaining prudent monetary and credit policies, a more progressive fiscal tax and expenditure system, higher public spending on health and education, deregulation and reforms to increase competition, measures to raise labor incomes and assist vulnerable workers, and better access to finance for both households and SMEs, including in rural areas. Not surprisingly, given the argued nexus between China’s growth strategy and inequality, many of these reforms are the same ones that would help rebalance its economy toward consumption and household incomes.

Cooperative and Islamic Banks: What can they Learn from Each Other?
Description: Islamic and cooperative banks such as credit unions are broadly similar in that they both share some risk with savers. However, risk sharing goes along with ownership control in cooperatives, whilst Islamic banks share risk with borrowers and downside risk with depositors. Islamic banking is consistent with mutual ownership, which may ease some of the governance and efficiency concerns implied by Shari’ah constraints. Greater risk sharing among cooperative bank stakeholders, using mechanisms embedded in Islamic financial products, may strengthen cooperatives’ financial resilience.

Capital Flows are Fickle: Anytime, Anywhere
Description: Has the unprecedented financial globalization of recent years changed the behavior of capital flows across countries? Using a newly constructed database of gross and net capital flows since 1980 for a sample of nearly 150 countries, this paper finds that private capital flows are typically volatile for all countries, advanced or emerging, across all points in time. This holds true across most types of flows, including bank, portfolio debt, and equity flows. Advanced economies enjoy a greater substitutability between types of inflows, and complementarity between gross inflows and outflows, than do emerging markets, which reduces the volatility of their total net inflows despite higher volatility of the components. Capital flows also exhibit low persistence, across all economies and across most types of flows. Inflows tend to rise temporarily when global financing conditions are relatively easy. These findings suggest that fickle capital flows are an unavoidable fact of life to which policymakers across all countries need to continue to manage and adapt.

Assessing the Impact and Phasing of Multi-year Fiscal Adjustment: A General Framework
Description: This paper provides a general framework to assess the output and debt dynamics of an economy undertaking multi-year fiscal adjustment. The framework allows country-specific assumptions about the magnitude and persistence of fiscal multipliers, hysteresis effects, and endogenous financing costs. In addition to informing macro projections, the framework can also shed light on the appropriate phasing of fiscal consolidation—in particular, on whether it should be front- or back-loaded. The framework is applied to stylized advanced and emerging economy examples. It suggests that for a highly-indebted economy undertaking large multi-year fiscal consolidation, high multipliers do not always argue against frontloaded adjustment. The case for more gradual or back-loaded adjustment is strongest when hysteresis effects are in play, but it needs to be balanced against implications for debt sustainability. Application to actual country examples tends to cast doubt on claims that very large multipliers have been operating post-crisis. It seems that the GDP forecast errors for Greece may have been due more to over-optimism on potential growth estimates than to underestimating fiscal multipliers.

The Driving Force behind the Boom and Bust in Construction in Europe
Description: This paper studies the factors behind pro-cyclical but widely varying construction shares (as a percent of GDP) across countries, with a strong focus on European countries. Using a dataset covering 48 countries (including advanced and emerging economies within and outside Europe) for 1990-2011, we find that country’s geography, demographics, and economic conditions are the key determinants of a norm around which actual construction shares revolve in a simple AR(1) and error-correction process. The empirical results show that in many European countries, construction shares overshoot relative to their norms before the recent global crisis, but they have fallen significantly since the crisis. Nevertheless, there is still room for further adjustment in construction shares in some countries which may weigh on economic recovery.

Testing the Prebisch-Singer Hypothesis since 1650: Evidence from Panel Techniques that Allow for Multiple Breaks
Description: In this paper, we re-examine two important aspects of the dynamics of relative primary commodity prices, namely the secular trend and the short run volatility. To do so, we employ 25 series, some of them starting as far back as 1650 and powerful panel data stationarity tests that allow for endogenous multiple structural breaks. Results show that all the series are stationary after allowing for endogeneous multiple breaks. Test results on the Prebisch-Singer hypothesis, which states that relative commodity prices follow a downward secular trend, are mixed but with a majority of series showing negative trends. We also make a first attempt at identifying the potential drivers of the structural breaks. We end by investigating the dynamics of the volatility of the 25 relative primary commodity prices also allowing for endogenous multiple breaks. We describe the often time-varying volatility in commodity prices and show that it has increased in recent years.

Dismal Employment Growth in EU Countries: The Role of Corporate Balance Sheet Repair and Dual Labor Markets
Description: This paper argues that the large differences among EU countries in post-crisis employment performance are to a large extent driven by the need to adjust corporate balance sheets, which had greatly deteriorated during the boom years in some countries but not in others. To close the large gaps between saving and investment, firms reduced investment and cut costs to boost profits. With much of the cost adjustment falling on firms’ wage bills, employment losses were largest in countries under the most intense pressures to improve corporate profitability and with limited wage flexibility due to labor market duality.
