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

Distributional Impacts of Heterogenous Carbon Prices in the EU
Description: We analyse the consequences of carbon price heterogeneity on households in The EU from 2010 to 2020. Accounting for both heterogeneity in carbon pricing across emission sources and the indirect effects from inter-industry linkages, we obtain two key findings. First, due to widespread carbon pricing exemptions, household burdens are lower than previously estimated. Second, lower-income groups are affected disproportionately, because they spend a smaller share of their expenditure on products that benefit from exemptions than their higher-income counterparts. Therefore, imposing uniform carbon prices both within and across countries would reduce carbon pricing regressivity on household expenditure in the EU. A global price would be most effective in this regard, as it would raise carbon prices embodied in EU imports. Further, because EU economies are open and apply higher average carbon prices than their trade partners, the domestic revenues exceed the costs embodied in EU household consumptions bundles. This increases the scope for reducing the burden of carbon pricing on lower-income households through revenue redistribution. Our results imply that the ongoing extension of carbon pricing to more sectors through the EU ETS II and the introduction of the EU’s CBAM should make carbon pricing less regressive, all else equal.

Stepping Up Venture Capital to Finance Innovation in Europe
Description: Relative to the US, productivity growth and investment in R&D in lagging in the EU, where it is more difficult to finance and scale up promising, innovative startups. Many of the most successful EU startups move elsewhere for financing, causing the EU to lose out on both the direct growth benefits and positive spillovers from these innovative firms. The EU could nurture innovative startups by accelerating the development of its venture capital (VC) ecosystem. Reducing regulatory frictions, especially ones that deter pensions funds and insurers from investing in VC, combined with well-designed tax incentives for R&D investments could help accelerate the development of the VC sector. These and other key CMU initiatives, such as the consolidation of stock markets and reforming and harmonizing insolvency regimes, will take time. Given the urgency to boost innovation, giving public financial institutions like the European Investment Fund a more active and expanded role in kickstarting VC markets where needed and in familiarizing investors with the VC asset class can be a helpful interim step.

Balancing Environmental, Fiscal, and Welfare Impacts of Transportation Decarbonization in France
Description: France has taken a leadership role in global mitigation and made significant progress towards reducing greenhouse gas emissions, but further efforts will be needed to meet domestic mitigation targets. Accelerating emissions reductions from road transportation will be a key part of this strategy, as they account for nearly one-third of national emissions. At the same time, with the shift to more lightly taxed electric vehicles over the next decade, fiscal revenue from the sector is projected to decline and externalities, such as congestion, to worsen. Building on existing policies, a comprehensive reform that combines revenue-neutral continuous feebate schemes with a gradual introduction of road user and congestion charges could support mitigation targets, while maintaining revenue and regulating externalities. This paper discusses administratively feasible options to introduce such policies as well as key welfare and distributional considerations.

Climate Transition Risk and Financial Stability in France
Description: This study empirically investigates the impact of the climate transition on the French financial sector using a micro-macro approach to examine the long-term effects of climate mitigation and decarbonization policies on sectoral output and the effects on firm profitability and the likelihood of corporate defaults. We employ a recursive-dynamic, multi-regional, multi-sectoral computable general equilibrium (CGE) model to simulate the Fit-for-55 climate scenario and then integrate the sectoral output paths derived from the model into firm-level corporate balance sheets and risks. We then assess the extent of credit exposure of banks to energy-intensive sectors. Our findings indicate that, under the Fit-for-55 scenario, the mining, chemicals and manufacturing sectors might face notable increases in their probability of defaults, in turn creating pockets of vulnerabilities in some parts of the banking system depending on their exposure to these energy-intensive sectors. This highlights the importance for a timely and orderly transition, including integrating climate transition plans into the prudential framework.

Bank Profitability in Europe: Not Here to Stay
Description: Slower passthrough of policy interest rate hikes to deposit rates relative to their loan rates has led to sharply wider bank net interest margins. Combined with resilient asset quality, wider net interest margins supported record profits for European banks in 2023. Drawing on historical data from the balance sheets and income statements of over 2,500 European banks, this paper shows that abnormally high profits are expected to fade soon as interest income will decline, once policy rates start being lowered, while higher impairment costs historically have weighed on profits with a lag. Moreover, a number of structural factors that have eroded the performance of European banks in the past two decades have largely remained unaddressed and will continue being a drag on profits and capital. Therefore, policymakers should encourage banks to preserve capital buffers and build resilience to future shocks, while exercising caution when considering taxes on profits or other measures that could divert potential sources of capital from banks.

A Multi-Country Study of Forward-Looking Economic Losses from Floods and Tropical Cyclones
Description: The study provides forward-looking estimates for economic damages from floods and tropical cyclones (TC) for a wide range of countries using global datasets. Damages are estimated for three Intergovernmental Panel on Climate Change (IPCC) scenarios and aggregated at the country level, building them from geographically disaggregated estimates of hazard severity and economic exposures across 183 countries. The results show that, for most countries, floods and TC’s damage rates increase (i) during the estimation span of 2020 to 2100, and (ii) with more severe global warming scenarios. In line with other global studies, expected floods and TCs damages are unevenly distributed across the world. The estimates can be used for a wide range of applications, as damage rates represent the key variable connecting climate scenarios to economics and financial sector risk analysis.

A Semi-Structural Model for Credit Cycle and Policy Analysis – An Application for Luxembourg
Description: The paper explores the nexus between the financial and business cycles in a semi-structural New Keynesian model with a financial accelerator, an active banking sector, and an endogenous macroprudential policy reaction function. We parametrize the model for Luxembourg through a mix of calibration and Bayesian estimation techniques. The model features dynamic properties that align with theoretical priors and empirical evidence and displays sensible data-matching and forecasting capabilities, especially for credit indicators. We find that the credit gap, which remained positive during COVID-19 amid continued favorable financial conditions and policy support, had been closing by mid-2022. Model-based forecasts using data up to 2022Q2 and conditional on the October 2022 WEO projections for the Euro area suggest that Luxembourg's business and credit cycles would deteriorate until late 2024. Based on these insights about the current and projected positions in the credit cycle, the model can guide policymakers on how to adjust the macroprudential policy stance. Policy simulations suggest that the weights given to measures of credit-to-GDP and asset price gaps in the macroprudential policy rule should be well-calibrated to avoid unwarranted volatility in the policy response.

Beyond Debt: Net Worth Fiscal Anchors
Description: This paper proposes anchoring medium- to long-term fiscal policy in a Public Sector Net Worth (PSNW) target. Such a target widens the scope of fiscal policy to include public sector assets, in addition to liabilities—the focus of debt-based rules. A PSNW target is directly relevant to ongoing policy debates on green fiscal rules and more generally, the reform of fiscal frameworks (such as the Euro Area’s) to allow for public investment in a high debt environment. Modeling a small open economy with public investment and endogenous growth, we show that, compared to debt-based anchors, a PSNW anchor is more conducive to public investment and economic growth, while providing for sensible policy reactions to changes in long-term interest rates. The net worth anchor also precludes unsustainable debt dynamics. Simulated transition dynamics show that replacing a debt anchor with a net worth anchor does not necessarily lead to higher debt-to-GDP ratios. In addition to the merits of a net worth anchor, the paper also discusses some operational challenges.

Unraveling the Wage-Output Disconnect: The Role of Labor Market Power
Description: In this paper, we theoretically and empirically explore the role of firm labor market power in the wage-output relationship. We start by laying out a theoretical model with imperfect labor mobility between firms and sectors, which implies upward-sloping labor supply curves that firms face, allowing firms to have labor market power (i.e., wage markdown). Assuming firm heterogeneity under oligopsony, markdowns can be represented as a function of firm labor market share. The model implies that firms with higher labor market share, indicated by a higher payroll share in their respective sectors, exhibit a weaker relationship between the changes in wages and output. We test the model’s prediction using data from the European subsample of the ORBIS dataset spanning from 2000 to 2018. We find that: (i) the pass-through of firm value added growth to wage growth is lower for firms with a higher payroll share in their sectors, with about one-fifth of the pass-through disappearing in firms at the top 1 percentile of the payroll share distribution, relative to an atomic firm; (ii) this pattern holds across various subsamples and timeframes, and also after accounting for several alternative explanations; and (iii) the weakening in the link between value added and wages growth due to firm labor market power intensifies during the downturns in the labor market or in the overall economy.
