What Prevents a Real Business Cycle Model from Matching the U.S. Data? Decomposing the Labor Wedge
Description: I carry out a business cycle accounting exercise (Chari, Kehoe and McGrattan, 2007) on the U.S. data measured in wage units (Farmer (2010)) for the entire postwar period. In contrast to a conventional approach, this approach preserves common medium-term business cycle fluctuations in GDP, its components and the unemployment rate. Additionally, it facilitates decomposition of the labor wedge into the labor supply and the labor demand wedges. Using this business cycle accounting methodology, I find that in the transformed data, most movements in GDP are accounted for by the labor supply wedge. Therefore, I reverse a key finding of the real business cycle literature which asserts that 70% or more of economic fluctuations can be explained by TFP shocks. In other words, the real business cycle model fits the data badly because the assumption that households are on their labor supply equation is flawed. This failure is masked by data that has been filtered with a conventional approach that removes fluctuations at medium frequencies. My findings are consistent with the literature on incomplete labor markets.

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.

Emissions and Growth: Trends and Cycles in a Globalized World
Description: Recent discussions of the extent of decoupling between greenhouse gas (GHG) emissions and real gross domestic product (GDP) provide mixed evidence and have generated much debate. We show that to get a clear picture of decoupling it is important to distinguish cycles from trends: there is an Environmental Okun's Law (a cyclical relationship between emissions and real GDP) that often obscures the trend relationship between emissions and real GDP. We show that, once the cyclical relationship is accounted for, the trends show evidence of decoupling in richer nations—particularly in European countries, but not yet in emerging markets. The picture changes somewhat, however, if we take into consideration the effects of international trade, that is, if we distinguish between production-based and consumption-based emissions. Once we add in their net emission transfers, the evidence for decoupling among the richer countries gets weaker. The good news is that countries with underlying policy frameworks more supportive of renewable energy and supportive of climate change tend to have greater decoupling between trend emissions and trend GDP, and for both production- and consumption-based emissions.
