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.

Monetary Policy Pass-Through to Interest Rates: Stylized Facts from 30 European Countries
Description: The extent to which changes in monetary policy rates lead to changes in loan and deposit rates for households and firms, referred to as ‘pass-through’, is an important ingredient of monetary policy transmission to output and prices. Using data on seven different bank interest rates in 30 European countries, different approaches, and the full sample as well as a subsample of euro area countries, we show that a) the pass-through in the post-pandemic hiking cycle has been heterogenous across countries and types of interest rates; b) the pass-through has generally been weaker and slower, except for rates of non-financial corporation loans and time deposits in euro area countries; c) differences in pass-through over time and across countries for most deposit rates are correlated with financial sector concentration, liquidity, and loan opportunities, and d) the effects of pass-through to outstanding mortgage rates on monetary transmission on prices and output are heterogenous across countries.

What Caused the Beveridge Curve to Shift Higher in the United States During the Pandemic?
Description: The Beveridge curve shifted substantially higher in the United States following the start of the COVID pandemic. In 2022, vacancies reached record highs across all sectors while unemployment fell to pre-pandemic lows. At the same time, the pandemic has resulted in severe labor shortages, and we estimate that the labor force was approximately 2 million below trend at the start of 2023. We exploit state-level data in the United States to find that lower immigration, higher excess mortality due to COVID, and falling older-worker labor force participation were associated with larger upward shifts in the Beveridge curve. We also find that states that had a larger employment concentration in contact-intensive sectors had larger upward shifts in their Beveridge curve. While the effect of sectoral reallocation and rehiring has been shown in theoretical models to lift the Beveridge curve, we show that worker shortages also result in an upward shift in the Beveridge curve if they increase the marginal product of labor. This result holds in a search and matching model with on-the-job search, but does not hold without on-the-job search.

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.

Searching for Wage Growth: Policy Responses to the “New Machine Age”
Description: The current wave of technological revolution is changing the way policies work. This paper examines the growth and distributional implications of three policies when “robot'' capital (a broad definition of robots, Artificial Intelligence, computers, big data, digitalization, networks, sensors and servos) is introduced in a neoclassical growth model. 1) cuts to the corporate tax rate; 2) increases in education spending; and 3) increases in infrastructure investment. We find that incorporating “robot'' capital into the model does make a big difference to policy outcomes: the trickle-down effects of corporate tax cuts on unskilled wages are attenuated, and the advantages of investment in infrastructure, and especially in education, are bigger. Based on our calibrations grounded on new empirical estimates, infrastructure investment and corporate tax cuts dominate investment in education in a "traditional" economy. However, in an economy with “robots” the infrastructure investment dominates corporate tax cuts, while investment in education tends to produce the highest welfare gains of all. The specific results, of course, may depend on the exact modeling of the technological change, but our main results remain valid and can provide more accurate welfare rankings.

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.
