The United States has pledged to become carbon neutral by 2050, meet sectoral objectives (e.g., for carbon free power, electric vehicles) and encourage greater mitigation among large emitting countries and of international transportation emissions. Fiscal policies at the national, sectoral, and international level could play a critical role in implementing these objectives, along with investment, regulatory, and technology policies. Fiscal instruments are cost-effective, can enhance political acceptability, and do not worsen, or could help alleviate, budgetary pressures. Domestically, a fiscal policy package could contain a mix of economy-wide carbon pricing and revenue-neutral feebates (i.e., tax-subsidy schemes) with the latter reinforcing mitigation in the transport, power, industrial, building, forestry, and agricultural sectors. Internationally, a carbon price floor among large emitters (with flexibility to implement equivalent measures) could effectively scale up global mitigation, while levies/feebates offer a practical approach for reducing maritime and aviation emissions.

This paper explores three possible transmission channels for transition risk shocks to the financial system in Norway. First, we estimate the direct firm-level impact of a substantial increase in domestic carbon prices under severe assumptions. Second, we map the impact of a drastic increase in global carbon prices on the domestic economy via the Norwegian oil sector. Third, we model the impact of a forced reduction in Norwegian oil firms’ output on shareholder portfolios. Results show that such a sharp increase in carbon prices would have a significant but manageable impact on banks. Finally, the paper discusses ways to advance the still evolving field of transition risk stress testing.

This 2019 Article IV Consultation discusses that driven by popular frustration with high levels of corruption and inequality, Haiti has been experiencing a protracted political crisis and prolonged civil unrest. The baseline scenario assumes some stabilization in the political situation by early 2020 but no major political or economic reforms. This would allow growth to recover only gradually and in the absence of sustained implementation of good policies and structural reforms, potential growth would remain low at about 1.4 percent over the medium term. Downside risks, both domestic and external, remain elevated. A prolongation of political instability, extreme natural disaster, drop in remittances, and/or a contraction in exports because of trade tensions would worsen the outlook, particularly given the absence of buffers and fragile social conditions. The challenge is to stabilize the macroeconomic situation in an unstable political context. The IMF Staff encourages the authorities to continue their efforts to contain the fiscal deficit and its monetary financing by the central bank. Improving domestic revenue collection and redirecting current spending would help create space for much needed social and capital expenditures. Together with steps to strengthen the central bank’s autonomy and legal framework, this would help reduce fiscal dominance.

A survey of the complex and intertwined set of forces behind the various commodity markets and the interplay between these markets and the global economy. Summarizes a rich set of facts combined with in-depth analyses distillated in a nontechnical manner. Includes discussion of structural trends behind commodities markets, their future implications, and policy implications.

This paper provides evidence of the causal impact of oil discoveries on development. Novel data on the drilling of 20,000 oil wells in Brazil allows us to exploit a quasi-experiment: Municipalities where oil was discovered constitute the treatment group, while municipalities with drilling but no discovery are the control group. The results show that oil discoveries significantly increase per capita GDP and urbanization. We find positive spillovers to non-oil sectors, specifically, an increase in services GDP which stems from higher output per worker. The results are consistent with greater local demand for non-tradable services driven by highly paid oil workers.

This 2015 Article IV Consultation highlights that Qatar is implementing an ambitious diversification strategy, while retaining its systemic role in the global natural gas market. Qatar accounts for one-third of global liquefied natural gas trade and has emerged as an important global financial investor, labor importer, and donor. The authorities are executing a large public infrastructure program to advance economic diversification and prepare for the FIFA 2022 World Cup. The economy has maintained strong growth momentum so far despite the large drop in oil prices since summer 2014. The short-term growth outlook is positive, but lower oil prices will lead to a substantial deterioration of the fiscal and external balances.

Mozambique has great potential in natural gas reserves and if liquefied/commercialized the sum of taxes and other fiscal revenue from natural gas will, at its peak, reach roughly one third of total fiscal revenue. Recent developments in the natural resource sector have triggered a fresh round of much needed infrastructure investment. This paper uses the DIGNAR model to simulate alternative public investment scaling-up plans in alternative LNG market scenarios. Results show that while a conservative approach, which simply awaits LNG revenues, would miss significant current growth opportunities, an aggressive approach would likely meet absorptive capacity constraints and imply a much bigger (and, in an adverse scenario, unsustainable) build-up of public debt. A gradual scaling up approach represents indeed a desirable path, as it allows anticipating some, though not all, of the LNG revenue and, even in an adverse scenario, keeping public debt at sustainable levels. Structural reforms affecting selection, governance and execution of public investment projects would significantly enhance the extent to which public capital is accumulated and impact non-resource growth and, ultimately, debt sustainability.

En dépit de ses vastes richesses pétrolières, l'Afrique centrale se débat encore pour promouvoir une croissance robuste et solidaire, ou pour offrir suffisamment de perspectives d'emploi à sa population, en particulier aux jeunes. S'appuyant sur de nouveaux travaux, cet ouvrage explique les défis macroéconomiques que doit relever la région, examine la gestion de la richesse pétrolière et ses répercussions pour la réduction de la pauvreté et présente quatre études de cas représentatives des enseignements qui ont été tirés.
