The HIPC Initiative and China’s Emergence as a Lender: post hoc or propter hoc?
Description: Twenty years after the Heavily Indebted Poor Countries (HIPC) debt relief initiative, debt levels in low-income countries are rising again, renewing sustainability concerns. The prevailing view suggests that China and other emerging lenders exploited the HIPC initiative to expand lending. Using a synthetic control method to generate a counterfactual, we find that, contrary to this narrative, China and other emerging lenders reduced net lending after debt relief; only multilateral creditors increased it. Furthermore, we find no support for the claim that debt relief encouraged lending to political allies. Overall, debt relief seems to have had limited influence on subsequent lending patterns.

Social Security Reforms, Retirement and Sectoral Decisions
Description: In many countries, the regulations governing pension systems, hiring procedures, and job contracts differ between the public and private sectors. Public sector employees tend to have longer tenures and higher wages compared to workers in the private sector. As such, social security reforms can affect both retirement decisions and sectoral choices. We study the effects of social security reforms on retirement and sectoral behavior in an economy with multiple pension systems. We develop a general equilibrium life-cycle model with heterogeneous agents, three sectors - private formal, private informal and public - and endogenous retirement. We quantitatively assess the long-run effects of reforms being discussed and implemented around the world. Among them, we study the unification of pension systems and increasing the minimum retirement age. We calibrate our model to Brazil, where several of the retirement conditions resemble those of other countries. We find that these reforms lower the likelihood of individuals to apply to a public job and increase the profile of savings over the life cycle. In the long run, these reforms lead to higher output and capital, reduced informality, and average welfare gains. They also drastically reduce the social security deficit.

An Evaluation of World Economic Outlook Forecasts: Any Evidence of Asymmetry?
Description: Using a large cross-country dataset covering over 150 countries and more than 10 macroeconomic variables, this study examines the consistency of IMF World Economic Outlook (WEO) forecasts with the full information rational expectations (FIRE) hypothesis. Similar to Consensus Economics forecasts, WEO forecasts exhibit an overreaction to news. Our analysis reveals that this overreaction is asymmetric, with more measured response to bad news, bringing forecasts closer to the FIRE benchmark. Moreover, forecasts align more closely with FIRE hypothesis during economic downturns or when a country is part of an IMF program. Overreaction becomes more pronounced for macroeconomic variables with low persistence and for forecasts over longer horizons, consistent with recent theoretical models. We also develop a model to explain how state-dependent nature of attentiveness may drive this asymmetric overreaction.

The Labor Market Decisions of Older Workers in Ageing Economies: Evidence from Spain and the UK
Description: Faced with fiscal pressures and labor shortages from ageing populations, Advanced Economies need to ease obstacles to longer working lives. In this paper, we discuss recent developments in employment and activity of workers aged 55 and above in Spain and the UK—two countries that differ widely on historical and recent employment rate patterns as well as institutional settings. We then explore themes related to their labor market decisions, including flows into and out of the labor force, health, working arrangements, and unemployment benefits systems. The differences and commonalities between the two countries highlight the diversity of obstacles to longer working lives and the need for policies to act upon all of them. Policy priorities include addressing worsening health, improving accessibility for older workers with physical limitations, providing incentives to return to employment for the long-term unemployed, and greater flexibility in hours and working arrangments for those who have family caring duties or want to gradually transition out of work.

Firm Performance, Business Supports and Zombification over the Pandemic
Description: Did the COVID-19 pandemic zombify the economy? Commentators have pointed to the pandemic and related business support measures potentially fueling zombification. Using administrative data covering the universe of Canadian firms, we find a broad-based decline in the share of zombie firms across industries relative to pre-pandemic levels. Whereas business support measures kept firms alive and operating as non-zombie firms, the decline in the zombie firm share was caused by would-be zombie firms exiting, indicative of the pandemic’s cleansing effects. As a consequence, while aggregate labour productivity worsened in Canada over the pandemic, it was not driven by zombie firms.

Spillovers from Large Emerging Economies: How Dominant Is China?
Description: This paper investigates the global economic spillovers emanating from G20 emerging markets (G20-EMs), with a particular emphasis on the comparative influence of China. Employing a Bayesian Global Vector Autoregression (GVAR) model, we assess the impacts of both demand-side and supply-side shocks across 63 countries, capturing the nuanced dynamics of global economic interactions. Our findings reveal that China's contribution to global economic spillovers significantly overshadows that of other G20-EMs. Specifically, China's domestic shocks have significantly larger and more pervasive spillover effects on global GDP, inflation and commodity prices compared to shocks from other G20-EMs. In contrast, spillovers from other G20-EMs are more regionally contained with modest global impacts. The study underscores China's outsized role in shaping global economic dynamics and the limited capacity of other G20-EMs to mitigate any potential negative implications from China's economic slowdown in the near term.

The Economic Costs of Temperature Uncertainty
Description: Beyond its environmental damage, climate change is predicted to produce significant economic costs. Combining novel high-frequency geospatial temperature data from satellites with measures of economic activity for the universe of US listed firms, this article examines a potentially important channel through which global warming can lead to economic costs: temperature uncertainty. The results show that temperature uncertainty—by increasing power outages, reducing labor productivity, and increasing the degree of exposure of firms to environmental and non-political risks, as well as economic uncertainty at the firm-level—persistently reduce firms’ investment and sales. This effect varies across firms, with those characterized by tighter financial constraints being disproportionally more affected.

Inattentiveness and the Investment Channel of Monetary Policy
Description: How does rational inattention interact with financial frictions? I provide new empirical evidence from survey data suggesting that this interaction likely plays a critical role in understanding macroeconomic dynamics. In a simple model, I demonstrate that financially constrained firms tend to be more attentive to economic conditions, consistent with my empirical findings. Embedding this mechanism into a DSGE model, I show that the aggregate investment response to a monetary policy shock depends on this interaction. The model further predicts that credit-constrained firms reduce their investment after an expansionary shock due to tighter borrowing constraints and higher production costs, a prediction I empirically confirm.

Long-Term Debt and Short-Term Rates: Fixed-Rate Mortgages and Monetary Transmission
Description: We study the two-way relationship between fixed-rate mortgages (FRMs) and monetary policy in a panel of up to 35 countries over the last two decades. The dataset includes quarterly information on the composition of mortgage flows and stock by type of rate-fixation and monetary policy shocks cleaned of information effects. Using instrumental-variablel local projections, we find both path- and state-dependency in monetary transmission. Monetary policy shapes mortgage choice, increasing (decreasing) the share of FRMs during easing (tightening) cycles. Over time, this mechanism alters the composition of the outstanding mortgage stock which, in turn, affects the central bank's ability to stabilize the economy ex-post. A greater (lower) prevalence of FRMs weakens (strengthens) monetary policy transmission to key macro-variables.

Designing Expenditure Policy Conditionality in IMF-Supported Programs
Description: This gap-filling paper provides granular advice on how to design quantitative and structural conditionality of IMF-supported programs in six expenditure policy areas: social assistance, energy subsidies, pension spending, health spending, education spending, and wage bill management. Such granular advice is based on a stocktaking exercise: an analysis of 105 programs approved between 2002 and July 2021 containing c.a. 1400 conditions. Conditions are key to identify outcomes or actions seen as critical for program success or monitoring, and so are essential for financial support countries can receive from the Fund.
