Greenflation Or Greensulation? The Case of Fuel Excise Taxes and Oil Price Pass-through


Book Description

Can a carbon tax reduce inflation volatility? Focusing on fuel excise taxes, this paper provides systematic evidence on their role as a shock absorber that helps mitigating the impact of global oil price shocks on domestic inflation. Exploiting substantial variation in fuel tax rates across 28 OECD countries over the period from 2014 to 2021, a simple idea that a per-unit, specific tax takes up a portion of the product price immune to cost shocks goes a long way toward explaining heterogeneity in the degree of oil price pass-through into domestic inflation across countries. A back-of-the-envelope calculation from the estimation results supports its quantitative significance---differences in fuel tax rates could explain about 30% of the variation in annual headline CPI inflation rates observed between the U.S. and U.K. during the 2021 inflation surge.




Can Energy Subsidies Help Slay Inflation?


Book Description

Many countries have used energy subsidies to cushion the effects of high energy prices on households and firms. After documenting the transmission of oil supply shocks empirically in the United States and the Euro Area, we use a New Keynesian modeling framework to study the conditions under which these policies can curb inflation. We first consider a closed economy model to show that a consumer subsidy may be counterproductive, especially as an inflation-fighting tool, when applied globally or in a segmented market, at least under empirically plausible conditions about wage-setting. We find more scope for energy subsidies to reduce core inflation and stimulate demand if introduced by a small group of countries which collectively do not have much influence on global energy prices. However, the conditions under which consumer energy subsidies reduce inflation are still quite restrictive, and this type of policy may well be counterproductive if the resulting increase in external debt is high enough to trigger sizeable exchange rate depreciation. Such effects are more likely in emerging markets with shallow foreign exchange markets. If the primary goal of using fiscal measures in response to spikes in energy prices is to shield vulnerable households, then targeted transfers are much more efficient as they achieve their goals at lower fiscal cost and transmit less to core inflation.




World Economic Outlook, October 2024


Book Description

The latest World Economic Outlook reports stable but underwhelming global growth, with the balance of risks tilted to the downside. As monetary policy is eased amid continued disinflation, shifting gears is needed to ensure that fiscal policy is on a sustainable path and to rebuild fiscal buffers. Understanding the role of monetary policy in recent global disinflation, and the factors that influence the social acceptability of structural reforms, will be key to promoting stable and more rapid growth in the future.




Fuel Taxes and the Poor


Book Description

Fuel Taxes and the Poor challenges the conventional wisdom that gasoline taxation, an important and much-debated instrument of climate policy, has a disproportionately detrimental effect on poor people. Increased fuel taxes carry the potential to mitigate carbon emissions, reduce congestion, and improve local urban environment. As such, higher gasoline taxes could prove to be a fundamental part of any climate action plan. However, they have been resisted by powerful lobbies that have persuaded people that increased fuel taxation would be regressive. Reporting on examples of over two dozen countries, this book sets out to empirically investigate this claim. The authors conclude that while there may be some slight regressivity in some high-income countries, as a general rule, fuel taxation is a progressive policy particularly in low income countries. Rich countries can correct for regressivity by cutting back on other taxes that adversely affect poor people, or by spending more money on services for the poor. Meanwhile, in low-income countries, poor people spend a very small share of their money on fuel for transport. Some costs from fuel taxes may be passed on to poor people through more expensive public transportation and food transport. Nevertheless, in general the authors find that gasoline taxes become more progressive as the income of the country in question decreases. This book provides strong arguments for the proponents of environmental taxation. It has immediate policy implications at the intersection of multiple subject areas, including transportation, environmental regulation, development studies, and climate change.

How Large and Persistent is the Response of Inflation to Changes in Retail Energy Prices?


Book Description

We estimate the dynamic effects of changes in retail energy prices on inflation using a novel monthly database, covering 110 countries over 2000:M1 to 2016:M6. We find that (i) inflation responds positively to retail energy price shocks, with effects being, on average, modest and transitory. However, our results suggest significant heterogeneity in the response of inflation to these shocks owing to differences in factors related to labor market flexibility, energy intensity, and monetary policy credibility. We also find compelling evidence of asymmetric effects—under sufficiently large shocks—in the case of high-income and low-income countries, with increases in retail fuel prices inducing larger effects on inflation than decreases in fuel prices.







Financial Regulation, Climate Change, and the Transition to a Low-Carbon Economy: A Survey of the Issues


Book Description

There are demands on central banks and financial regulators to take on new responsibilities for supporting the transition to a low-carbon economy. Regulators can indeed facilitate the reorientation of financial flows necessary for the transition. But their powers should not be overestimated. Their diagnostic and policy toolkits are still in their infancy. They cannot (and should not) expand their mandate unilaterally. Taking on these new responsibilities can also have potential pitfalls and unintended consequences. Ultimately, financial regulators cannot deliver a low-carbon economy by themselves and should not risk being caught again in the role of ‘the only game in town.’




Can International Technological Diffusion Substitute for Coordinated Global Policies to Mitigate Climate Change?


Book Description

In short, yes. I use a multi-region integrated assessment model with fuel-specific endogenous technical change to examine the impact of Europe and China reducing emissions to zero by mid-century. Without international technological diffusion this is insufficient to avoid catastrophic climate change. But when innovation can diffuse overseas, long-run temperature increases are limited to 3 degrees. This occurs because policy not only encourages green innovations but also dissuades dirty innovations which would otherwise spread. The most effective policy package in emissions-reducing regions is a research subsidy funded by a carbon tax, driven in the short term by the direct effect of the carbon tax on the composition of energy, and later by innovation induced by research subsidies. Green production subsidies are ineffective because they undermine incentives for innovation.




Mitigating Climate Change: Growth-Friendly Policies to Achieve Net Zero Emissions by 2050


Book Description

Background paper prepared for the October 2020 IMF World Economic Outlook. This paper provides a detailed presentation of the simulation results from the October 2020 IMF World Economic Outlook chapter 3 and an additional scenario with carbon pricing only for comparison with the comprehensive policy package where green investments were also included. This paper has greatly benefitted from continuous discussions with Oya Celasun and Benjamin Carton on the design of simulations; contributions from Philip Barrett for part of the simulations; and research support from Jaden Kim. We also received helpful comments from other IMF staff. All remaining errors are ours.

Are Climate Change Policies Politically Costly?


Book Description

Are policies designed to avert climate change (Climate Change Policies, or CCPs) politically costly? Using data on governmental popular support and the OECD’s Environmental Stringency Index, we find that CCPs are not necessarily politically costly: policy design matters. First, only market-based CCPs (such as emission taxes) generate negative effects on popular support. Second, the effects are muted in countries where non-green (dirty) energy is a relatively small input into production. Third, political costs are not significant when CCPs are implemented during periods of low oil prices, generous social insurance and low inequality.
