Growth Breaks and Growth Spells in Sub-Saharan Africa
Description: This paper examines the growth performance of sub-Saharan African countries since 1960 through the lens of growth turning points (accelerations and decelerations) and periods of sustained growth (growth spells). Growth accelerations are generally associated with improved external conditions, increased investment and trade openness, declines in inflation, better fiscal balances, and improvements in the institutional environment. Transitioning from growth accelerations to growth spells often requires additional efforts beyond what is needed to trigger an acceleration. Growth spells are sustained by fiscal policy that prevents excessive public debt accumulation, monetary policy geared toward low inflation, outward-oriented trade policies, and structural policies that reduce market distortions, as well as supportive external environment and improvements in democratic institutions. Overall, determinants of growth spells in sub-Saharan Africa are different from those in the rest of the emerging and developing countries.

The Effect of Leverage on Asset Sales Between Financial Institutions
Description: This paper analyzes how the leverage of financial institutions affects their demand for assets and the resulting value of transactions between financial institutions. The results show a positive relationship between buyer capital and the likelihood of buying assets, and between buyer capital and the value of the deal. That is, those institutions that are the least constrained in their ability to raise funding are those that demand assets and pay more for them. This result does not hold, however, for deposit-taking institutions that had access to several government programs designed to improve their liquidity position during the crisis of 2008.

Banking on Women Leaders: A Case for More?
Description: Using a new dataset, we measure the large gap between the representation of men and women in leadership positions in banks and bank supervision agencies worldwide. Women occupied less than 2 percent of bank CEOs positions, and less than 20 percent of the board seats in more than 80 percent of the observations across banks over time. Contrary to common perceptions, many low- and middle-income countries have a higher share of women in bank boards and banking supervision agency boards compared to advanced economies. Econometric analysis suggests that, controlling for relevant bank and country-specific factors, the presence of women as well as a higher share of women on bank boards is associated with greater bank stability, as represented by higher z-scores and lower nonperforming loan ratios. We also examine the share of women on boards of banking supervision agencies by compiling a new dataset. We find that it is associated with greater bank stability. Further research is needed to identify specific mechanisms through which these stability benefits are achieved, and to understand the conditions that have facilitated entry of women into leadership roles in banks and supervision agencies.

Fiscal Stabilization and Growth: Evidence from Industry-level Data for Advanced and Developing Economies
Description: Medium-term growth can be enhanced by fiscal stabilization. However, to date, no systematic effort has been made to study the specific channels through which fiscal stabilization affects growth. This paper examines the effect of fiscal stabilization on industrial growth and how this effect depends on different technological characteristics. It does so by applying a difference-in-difference approach to an unbalanced panel of 22 manufacturing industries for 55 advanced and developing economies over the period 1970-2014. The results suggest that fiscal stabilization fosters growth in industries with: i) higher external financial dependence and lower asset fixity; ii) higher degree of labor intensity; iii) higher investment lumpiness and relationship-specific input usage. These effects tend to be larger during economic recessions. The results are robust to different measures of fiscal stabilization and the inclusion of various interactions between a broad set of macroeconomic variables and production technologies.

Benchmarking Social Spending Using Efficiency Frontiers
Description: Developing and low-income economies face the challenge of increasing public spending to address sizeable infrastructure and social gaps while simultaneously restoring the fiscal discipline weakened to countervail the effect of the global recession. Increasing the efficiency of social spending could be the key policy to address the dilemma as it allows the optimization of the existing resources by reducing spending inefficiencies. This paper quantifies the efficiency gap in the health and education sectors for a large sample of developing and emerging countries and proposes measures to reduce these gaps for the specific cases of El Salvador, Guatemala, and Honduras.

Oil Prices and Inflation Dynamics: Evidence from Advanced and Developing Economies
Description: We study the impact of fluctuations in global oil prices on domestic inflation using an unbalanced panel of 72 advanced and developing economies over the period from 1970 to 2015. We find that a 10 percent increase in global oil inflation increases, on average, domestic inflation by about 0.4 percentage point on impact, with the effect vanishing after two years and being similar between advanced and developing economies. We also find that the effect is asymmetric, with positive oil price shocks having a larger effect than negative ones. The impact of oil price shocks, however, has declined over time due in large part to a better conduct of monetary policy. We further examine the transmission channels of oil price shocks on domestic inflation during the recent decades, by making use of a monthly dataset from 2000 to 2015. The results suggest that the share of transport in the CPI basket and energy subsidies are the most robust factors in explaining cross-country variations in the effects of oil price shocks during the this period.

The Political Economy of Fiscal Transparency and Independent Fiscal Councils
Description: The global surge in independent fiscal councils (IFCs) raises three related questions: How can IFCs improve the conduct of fiscal policy? Are they simultaneously desirable for voters and elected policymakers? And are they resilient to changes in political conditions? We build a model in which voters cannot observe the true competence of elected policymakers. IFCs’ role is to mitigate this imperfection. Equilibrium public debt is excessive because policymakers are “partisan” and “opportunistic.” If voters only care about policymakers’ competence, both the incumbent and the voters would be better off with an IFC as the debt bias would shrink. However, when other considerations eclipse competence and give the incumbent a strong electoral advantage or disadvantage, setting up an IFC may be counterproductive as the debt bias would increase. If the incumbent holds a moderate electoral advantage or disadvantage, voters would prefer an IFC, but an incumbent with a large advantage may prefer not to have an IFC. The main policy implications are that (i) establishing an IFC can only lower the debt bias if voters care sufficiently about policymakers’ competence; (ii) not all political environments are conducive to the emergence of IFCs; and (iii) IFCs are consequently vulnerable to shifts in political conditions.

Western Balkans: Increasing Women's Role in the Economy
Description: The Western Balkan countries have some of the lowest female labor force participation and employment rates across Europe. Almost two-thirds of working age women in the region are either inactive or unemployed: a huge bite into human capital for a region that endures high emigration and faces declining working age population. The paper uses both macro- and micro-level data to explore what explains low participation and employment rates among women in the region. Our findings show that improving educational attainment, having a more balanced family leave policy, and reducing tax wedge help improve participation of women in the labor force. However, these measures are not enough to notably improve employability of women, which require stronger growth supported by robust institutions.

How Important is the Global Financial Cycle? Evidence from Capital Flows
Description: This study quantifies the importance of a Global Financial Cycle (GFCy) for capital flows. We use capital flow data dis-aggregated by direction and type between 1990Q1 and 2015Q5 for 85 countries, and conventional techniques, models and metrics. Since the GFCy is an unobservable concept, we use two methods to represent it: directly observable variables in center economies often linked to it, such as the VIX; and indirect manifestations, proxied by common dynamic factors extracted from actual capital flows. Our evidence seems mostly inconsistent with a significant and conspicuous GFCy; both methods combined rarely explain more than a quarter of the variation in capital flows. Succinctly, most variation in capital flows does not seem to be the result of common shocks nor stem from observables in a central country like the United States.

Macroeconomic and Distributional Effects of Personal Income Tax Reforms: A Heterogenous Agent Model Approach for the U.S
Description: This paper assesses the macroeconomic and distributional impact of personal income tax (PIT) reforms in the U.S. drawing on a multi-sector heterogenous agents model in which consumers have non-homothetic preferences and sectors differ in terms of their relative labor and skill intensity. The model is calibrated to key characteristics of the US economy. We find that (i) PIT cuts stimulate growth but the supply side effects are never large enough to offset the revenue loss from lower marginal tax rates; (ii) PIT cuts do “trickle-down” the income distribution: tax cuts stimulate demand for non-tradable services which raise the wages and employment prospects of low-skilled workers even if the tax cut is not directly incident on them; (iii) A revenue neutral tax plan that reduces PIT for middle-income groups, raises the consumption tax, and expands the Earned Income Tax Credit can have modestly positive effects on growth while reducing income polarization; (iv) The growth effects from lower income taxes are concentrated in non-tradable service sectors although the increased demand for tradable goods generate positive spillovers to other countries; (v) Tax cuts targeted to higher income groups have a stronger growth impact than tax cuts for middle income households but significantly worsen income polarization, even after taking into account trickle-down effects and an expansion of the Earned Income Tax Credit.
