In Search of the Origin of Original Sin Dissipation
Description: In this paper, we examine how, contrary to the ‘original sin’ hypothesis, emerging market economies have gained the ability to borrow abroad in their local currency. We empirically analyze the relationship of various economic variables with local currency debt and identify three crucial conditions for the capacity to borrow in local currency: institutional quality, sufficient depth in the domestic bond market, and adequate performance in inflation targeting. While shares in JPMorgan Government Bond Index-Emerging Markets (GBI-EM) index also appear to be influential, the associations with local currency debt is less clear. We conduct a similar empirical analysis on portfolio equity, which represents a safer form of external liability than foreign currency debt, and verify that the depth of the equity market plays a key role in attracting foreign capital to domestic equity markets. Finally, we propose a simple portfolio model based on the inelastic market hypothesis to explain the positive correlation between capital market depth and the dissipation of original sin, which refers to the presence of more external liability in the form of equity or local currency debt. In essence, our analysis suggests that emerging market economies with reasonably strong fundamentals are not necessarily reliant on foreign currency debt.

The Leisure Gains from International Trade
Description: The average number of hours worked has been declining in many countries. This can be explained if workers have preferences with income effects outweighing substitution effects. Then, an optimal response to rising income is to reduce labor supply to enjoy more leisure. In this paper, I develop a novel structural link between trade and aggregate labor supply. Using a multi-country Ricardian trade model, I show that reducing trade barriers leads to fewer hours worked while being compatible with an increase in welfare. In addition, I derive an hours-to-trade elasticity and estimate it by exploiting exogenous income variation generated by aggregate trade. On average, I quantify that the rise in trade openness between 1950 and 2014 explains 7 percent of the total decline in hours per worker in high-income countries.

Fueling or Following Growth? Causal Effects of Capital Inflows on Recipient Economies
Description: Identifying the causal impact of capital inflows on growth and development has been a perennial challenge. This paper proposes a new way to investigate the effect of capital flows on recipient emerging and developing economies, using shift-share instruments and correcting for indirect flows. It finds a significantly beneficial effect of loan and bond inflows on economic performance, which materializes after a few years. It also finds some confirmation that the absorptive capacity of recipient economies depends on their fundamentals.

U.S. Monetary Policy Spillovers to Middle East and Central Asia: Shocks, Fundamentals, and Propagations
Description: We empirically examine U.S. monetary policy spillovers to the Middle East and Central Asia (ME & CA) region by decomposing U.S. interest rates changes into two orthogonal shocks: the pure monetary policy shock and the information news shock. Using a sample of 16 ME & CA countries, we find that when interest rates increase, the two shocks have opposite spillovers on the region. Tightening driven by contractionary monetary policy shocks hinders growth, while tightening driven by positive information news shocks boosts growth despite higher interest rates. Countries with weaker fundamentals face more negative spillovers from contractionary monetary policy shocks but may sometimes benefit more from positive information news shocks. Moreover, high oil prices mitigate both spillovers for oil exporters while global risk appetite amplifies both spillovers. Finally, we estimate a large degree of heterogeneity in the impact of the 2022 U.S. tightening cycle on ME & CA countries, with oil exporters with stronger fundamentals withstanding well the shock and oil importers with weaker fundamentals being hit the most.

The Macroeconomic Consequences of Import Tariffs and Trade Policy Uncertainty
Description: We estimate the macroeconomic effects of import tariffs and trade policy uncertainty in the United States, combining theory-consistent and narrative sign restrictions in Bayesian SVARs. We find mostly adverse consequences of protectionism, in aggregate and across sectors and regions. Tariff shocks are more important than trade policy uncertainty shocks. Tariff shocks depress trade, investment, and output persistently. The general equilibrium import elasticity is –0.8. Historically, NAFTA/WTO raised output by 1-3% for twenty years. Undoing the 2018/19 measures would raise output by 4% over three years. The findings imply higher gains of trade than partial equilibrium or static trade models.

The Shifting and Steepening of Phillips Curves During the Pandemic Recovery: International Evidence and Some Theory
Description: We study the global inflation surge during the pandemic recovery and the implications for aggregate and sectoral Phillips curves. We provide evidence that Phillips curves shifted up and steepened across advanced economies, and that differences in the inflation response across sectors imply the relative price of goods has been pro-cyclical this time around rather than a-cyclical as during previous cycles. We show analytically that these three features emerge endogenously in a two-sector new-Keynesian model when we introduce unbalanced recoveries that run against a supply constraint in the goods sector. A calibrated exercise shows that the resulting changes to the output-inflation relation are quantitatively important and improve the model's ability to replicate the inflation surge during this period.

Energy Security and The Green Transition
Description: The current energy crisis has raised important policy questions on how to strengthen short-term energy security while remaining firmly committed to the green transition, a challenge amplified by the recent consensus at COP28 to transition away from fossil fuels. This paper examines the historical determinants of the security of energy supply and analyzes the green transition implications for energy security. Looking back, we find that the diversification of energy trade partners, or the lack thereof, was the main factor that underpinned energy security dynamics within and across countries over the last two decades. Looking ahead, the green transition is expected to have a net positive effect on energy security provided investments are aligned to address new challenges posed by the increased reliance on renewables.

Did the U.S. Really Grow Out of Its World War II Debt?
Description: The fall in the U.S. public debt/GDP ratio from 106% in 1946 to 23% in 1974 is often attributed to high rates of economic growth. This paper examines the roles of three other factors: primary budget surpluses, surprise inflation, and pegged interest rates before the Fed-Treasury Accord of 1951. Our central result is a simulation of the path that the debt/GDP ratio would have followed with primary budget balance and without the distortions in real interest rates caused by surprise inflation and the pre-Accord peg. In this counterfactual, debt/GDP declines only to 74% in 1974, not 23% as in actual history. Moreover, the ratio starts rising again in 1980 and in 2022 it is 84%. These findings imply that, over the last 76 years, only a small amount of debt reduction has been achieved through growth rates that exceed undistorted interest rates.

Fraying Threads: Exclusion and Conflict in Sub-Saharan Africa
Description: This study investigates the factors leading to exclusion and their detrimental impacts in sub-Saharan Africa (SSA). It employs two-levels of analysis: a macro-level estimation of the influence of exclusion and marginalization on violent conflict, and a micro-level investigation identifying the triggers of exclusion sentiments. We construct statistical summaries from multiple measures of exclusion, producing an overall exclusion index as well as social, economic, and political exclusion sub-indices. Our results show the importance of mitigating exclusion and marginalization within SSA nations, and pinpoint the most effective policy levers that governments may use to minimize destabilizing feelings of exclusion.

Dissecting the Decline in Average Hours Worked in Europe
Description: Three years after the COVID-19 crisis, employment and total hours worked in Europe fully recovered, but average hours per worker did not. We analyze the decline in average hours worked across European countries and find that (i) it is not cyclical but predominantly structural, extending a long-term trend that predates COVID-19, (ii) it mainly reflects reduced hours within worker groups, not a compositional shift towards lower-hours jobs and workers, (iii) men—particularly those with young children—and youth drive this drop, (iv) declines in actual hours match declines in desired hours. Policy reforms could help involuntary parttimers and women with young children raise their actual hours towards desired levels, but the aggregate impact on average hours would be limited to 0.5 to 1.5 percent. Overall, there is scant evidence of slack at the intensive margin in European labor markets, and the trend fall in average hours worked seems unlikely to reverse.
