The energy transition requires substantial amounts of metals such as copper, nickel, cobalt and lithium. Are these metals a key bottleneck? We identify metal-specific demand shocks, estimate supply elasticities and pin down the price impact of the energy transition in a structural scenario analysis. Metal prices would reach historical peaks for an unprecedented, sustained period in a net-zero emissions scenario. The total value of metals production would rise more than four-fold for the period 2021 to 2040, rivaling the total value of crude oil production. Metals are a potentially important input into integrated assessments models of climate change.
This paper investigates the short-term effects of fiscal consolidation on economic activity in OECD economies. We examine the historical record, including Budget Speeches and IMFdocuments, to identify changes in fiscal policy motivated by a desire to reduce the budget deficit and not by responding to prospective economic conditions. Using this new dataset, our estimates suggest fiscal consolidation has contractionary effects on private domestic demand and GDP. By contrast, estimates based on conventional measures of the fiscal policy stance used in the literature support the expansionary fiscal contractions hypothesis but appear to be biased toward overstating expansionary effects.
This paper explains specifics of stress testing at the IMF. After a brief section on the evolution of stress tests at the IMF, the paper presents the key steps of an IMF staff stress test. They are followed by a discussion on how IMF staff uses stress tests results for policy advice. The paper concludes by identifying remaining challenges to make stress tests more useful for the monitoring of financial stability and an overview of IMF staff work program in that direction. Stress tests help assess the resilience of financial systems in IMF member countries and underpin policy advice to preserve or restore financial stability. This assessment and advice are mainly provided through the Financia...
Crises on external sovereign debt are typically defined as defaults. Such a definition accurately captures debt-servicing difficulties in the 1980s, a period of numerous defaults on bank loans. However, defining defaults as debt crises is problematic for the 1990s, when sovereign bond markets emerged. In contrast to the 1980s, the 1990s are characterized by significant foreign debt-servicing difficulties but fewer sovereign defaults. In order to capture this evolution of debt markets, we define debt crises as events occurring when either a country defaults or its bond spreads are above a critical threshold. We find that our definition outperforms the default-based definition in capturing debt-servicing difficulties and, consequently, in fitting the post-1994 period. In particular, liquidity indicators are significant in explaining our definition of debt crises, while they do not play any role in explaining defaults after 1994.
This paper studies the historical importance of OPEC for oil price fluctuations. An event-study approach is used to identify the effects of OPEC announcements on oil price fluctuations. Results show that price volatility is higher than typical around OPEC meetings. Also, members' compliance, a proxy for credibility, has strongly fluctuated over time. An ordered multinomial logit framework identifies the main factors that explain OPEC's decisions to cut, maintain, or boost members' oil production and is able to successfully predict OPEC meeting outcomes 66 percent of the time, between 1989 and 2019. Cyclical oil price fluctuations (as opposed to persistent shifts in levels) drive OPEC’s decisions, suggesting that OPEC's objective is to stabilize the oil price rather than countering fundamental shifts in demand and supply. Low OPEC’s market share reduces the probability of a production cut. Finally, the transparency of OPEC's statements has modestly improved between 2002 and 2019.
We study how two aspects of food insecurity - caloric insufficiency and diet composition - are affected by aggregate economic fluctuations. The use of cross-country panel data allows us to adopt a global prospective on the identification of the macroeconomic determinants of food insecurity. Income shocks are the most relevant driver of food insecurity, displaying high elasticities at the early stages of economic development. The role of food price shocks is more limited. Social protection has a direct effect and mitigates the impact of income shocks. Effects are highly heterogeneous across a range of structural characteristics of the economy, highlighting the role of distributional aspects and of food import dependency.
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.
Tonga’s economic activity has strengthened, bolstered by consistent remittance flows, continued tourism recovery, and robust construction activities, despite a fall in agricultural output. The potential for a stronger recovery has, however, been hindered by supply-side constraints including labor shortages. Inflationary pressures have eased, and headline inflation is falling below the 5 percent reference rate of the National Reserve Bank of Tonga (NRBT), mainly driven by the moderation of global goods and commodity prices. The elevated frequency of natural disasters, limited economies of scale, and geographical remoteness collectively temper medium-term growth. Localized risks are emerging in the banking sector.
Governments issue debt for good and bad reasons. While the good reasons—intertemporal tax-smoothing, fiscal stimulus, and asset management—can explain some of the increases in public debt in recent years, they cannot account for all of the observed changes. Bad reasons for borrowing are driven by political failures associated with intergenerational transfers, strategic manipulation, and common pool problems. These political failures are a major cause of overborrowing though budgetary institutions and fiscal rules can play a role in mitigating governments’ tendencies to overborrow. While it is difficult to establish a clear causal link from high public debt to low output growth, it is likely that some countries pay a price—in terms of lower growth and greater output volatility—for excessive debt accumulation.
Data for a Greener World presents a structured discussion on how to measure the economic and financial dimensions of climate change. It combines economic theory and analysis with real world examples of how climate data can be constructed for different country settings, based on existing climate science and economic data. The book identifies important climate data gaps, as well as practical and innovative approaches to close many of these gaps. The book discusses how to track greenhouse gas emission by production and consumption (Chapters 1-2), which lead to physical risks (Chapters 3-4) and transition risks (Chapters 5-7) and concludes with cross-border implications of climate risks (Chapter...
