Carbon Prices and Inflation in the Euro Area
Description: What is the effect of carbon pricing on inflation? This paper shows empirically that the consequences of the European Union’s Emission Trading System (ETS) and national carbon taxation on inflation have been limited in the euro area, so far. This result is supported by analysis based on a panel local projections approach, as well as event studies based on individual countries. Our estimates suggest that carbon taxes raised the price of energy but had limited effects on overall consumer prices. Since future climate policy will need to be much more ambitious compared to what has been observed so far, including the need for larger increases in carbon prices, possible non-linearities might make extrapolating from historical results difficult. We thus also use input-output tables to simulate the mechanical effect of a carbon tax consistent with the EU’s ‘Fit-for-55’ commitments on inflation. The required increase of effective carbon prices from around 40 Euro per ton of CO2 in 2021 to around 150 Euro by 2030 could raise annual euro area inflation by between 0.2 and 0.4 percentage points. It is worth noting that the energy price increases caused by the rise in the effective carbon price to 150 Euro is substantially smaller than the energy price spike seen in 2022 following the invasion of Ukraine.

The Legal Foundations of Public Debt Transparency: Aligning the Law with Good Practices
Description: Debt opacity burdens the public and can exacerbate debt vulnerabilities in many countries. Both low-income and developing countries and emerging market economies have critical gaps in debt transparency, and the implementation of international standards and guidelines has lagged. The paper surveys the legal frameworks of sixty jurisdictions and reveals the critical weaknesses that hinder debt transparency, which include weak reporting obligations, limited coverage of public debt, inadequate monitoring, unclear borrowing and delegation processes, unfettered confidentiality arrangements and weak accountability mechanisms. Because laws entrench practices and bind the discretion of policy makers and debt managers alike, subjecting them to public scrutiny, legal reform is a necessary part of any solution to the problem of hidden debt, though it may entail a difficult and time intensive process in many jurisdictions.

Platform Precommitment via Decentralization
Description: I study an entrepreneur’s incentives to build a decentralized platform using a blockchain. The entrepreneur can either build the platform using a regular company and retain control of the platform, or build the platform using a blockchain and surrender control of the platform. In either case, the platform’s users experience a locked-in effect. I show that a decentralized implementation of the platform is both (i) more profitable for the entrepreneur and (ii) a Pareto improvement, if and only if the size of the locked-in effect exceeds some threshold. Further, progressive decentralization through airdrops can be optimal.

Firms’ Resilience to Energy Shocks and Response to Fiscal Incentives: Assessing the Impact of 2022 Energy Crisis
Description: The energy price shock in 2022 led to government support for firms in some countries, sparking debate about the rationale and the nature of such support. The results from nationally representative firm surveys in the United States and Germany indicate that firms in these countries were generally resilient. Coping strategies adopted by firms included the pass-through of higher costs to consumers, adjustment of profit margins (United States) and investments in energy saving and efficiency (Germany). Firms in energy-intensive industries would have been significantly more affected if international energy prices were fully passed through to domestic prices in Europe. Survey responses further reveal that most firms are uncertain about the impact of recent policy announcments on green subsidies. Firms take advantage of fiscal incentives to accelerate their climate-related investment plans are often those that have previous plans to do so. These findings suggest better targeting and enhancing policy certainty will be important when facilitate the green transition among firms.

The Impact of Derivatives Collateralization on Liquidity Risk: Evidence from the Investment Fund Sector
Description: Stricter derivative margin requirements have increased the demand for liquid collateral, but euro area investment funds, which use derivatives extensively, have been reducing their liquid asset holdings. Using transaction-by-transaction derivatives data, we assess whether the current levels of funds’ holdings of cash and other highly liquid assets would be adequate to meet funds’ liquidity needs to cover variation margin calls on derivatives under a range of stress scenarios. The estimates indicate that between 13 percent and 33 percent of euro area funds with sizeable derivatives exposures may not have sufficient liquidity buffers to meet the calls under adverse market shocks. As a result, they are likely to redeem money market fund (MMF) shares, procyclically sell assets, and draw on credit lines, thus amplifying the market dynamics under such stress scenarios. Our findings highlight the importance of further work to assess the potential role of macroprudential policies for nonbanks, particularly regarding liquidity risk in funds.

U.S. Inflation Expectations During the Pandemic
Description: This paper studies how and why inflation expectations have changed since the emergence of Covid-19. Using micro-level data from the University of Michigan Survey of Consumers, we show that the distribution of consumer expectations at one-year and five-ten year horizons has widened since the surge of inflation during 2021, along with the mean. Persistently high and heterogeneous expectations of consumers with less education and lower income are mainly responsible. A simple model of adaptive learning is able to mimic the change in inflation expectations over time for different demographic groups. The inflation expectations of low income and female consumers are consistent with using less complex forecasting models and are more backward-looking. A medium-scale DSGE model with adaptive learning, estimated during 1965-2022, has a time-varying solution that produces lower forecast errors for inflation than a variant with rational expectations. The estimated model interprets the surge of inflation in 2021 mainly as the result of a price markup shock, which is more persistent and requires a larger and more persistent monetary policy response than under rational expectations.

Emissions Reduction, Fiscal Costs, and Macro Effects: A Model-based Assessment of IRA Climate Measures and Complementary Policies
Description: The IMF’s Macroeconomic Model for the Energy Transition (GMMET) is applied to assess the climate-related measures in the U.S. 2022 Inflation Reduction Act (IRA). Explicitly accouting for corporate income tax funding and assuming no permitting delays for energy-related investment, the measures are expected to cut annual greenhouse gas emissions by 710 MMT by 2030, predominantly driven by more electricity generation from renewables combined with a rising share of electric vehicles. Aggregate output and inflation are not impacted significantly, while the fiscal costs amount to about $700 billion through 2030 (another $120 billion of fixed grants and loans are not modelled). In the presence of investment delays from permitting, emission cuts would be reduced by about a third. We also show that the IRA leaves room for sizable additional emission abatement at very low costs; by targeting electricity generation from coal and methane emissions from oil and gas industries.

The Housing Supply Channel of Monetary Policy
Description: We study the role of regional housing markets in the transmission of US monetary policy. Using a FAVAR model over 1999q1–2019q4, we find sizeable heterogeneity in the responses of US states to a contractionary monetary policy shock. Part of this regional variation is due to differences in housing supply elasticities, household debt overhang, and housing wealth (volatility). Our analysis indicates that house prices and consumption respond more in supply-inelastic states and in states with large household debt imbalances, where negative housing wealth effects bite more strongly and borrowing constraints become more binding. Moreover, financial stability risks increase sharply in these areas as mortgage delinquencies and foreclosures surge, worsening banks’ balance sheets. Finally, monetary policy may have a stronger effect on housing tenure decisions in supply-inelastic states, where the homeownership rate and price-to-rent ratios decline by more. Our findings stress the importance of regional housing supply conditions in assessing the macrofinancial effects of rising interest rates.

Geopolitics and International Trade: The Democracy Advantage
Description: Do political regimes determine how geopolitics influence international trade? This paper provides an empirical answer to the question by analyzing the joint impact of democracy and geopolitical distance between countries with an augmented gravity model of bilateral trade flows and an extensive dataset of more than 4 million observations on 59,049 country-pairs over the period 1948–2018. Implementing the Poisson Pseudo-Maximum Likelihood regression and the two-stage least squares with instrumental variable approach, I find that geopolitical developments are not as important as income and geographical distance in determining bilateral trade flows and that democracy fosters international trade and moderates the potential negative impact of geopolitics. While the impact of democracy and its interaction with geopolitical distance are significant across all countries, the magnitude of these effects is substantially larger in advanced economies than in developing countries, reflecting the greater strength of democratic institutions, on average, in advanced economies.

ASAP: A Conceptual Model for Digital Asset Platforms
Description: This working paper inaugurates the "Technology Fundamentals for Digital Finance" series, concentrating on the technical aspects of financial Digital Assets. The series aims to facilitate the use of a clear terminology in a nascent platform-oriented paradigm of financial infrastructures, by laying the groundwork for technical discussions on digital asset standards. The paper introduces a conceptual model named ASAP (Access, Service, Asset, Platform) for Digital Asset Platforms (DAP), leveraging insights from IT industry practices and experiments by central banks. The ASAP model is illustrated through examples and use cases of tokenized assets, to demonstrate the possible usage and merits of modeling Digital Asset Platforms with four layers. Just as the utilization of a seven-layer model (often refered to as TCP/IP) has been fundamental to the interoperability of the internet, it is anticipated that the four-layer ASAP model for Digital Asset Platforms will similarly promote cross-platform interoperability, including across various jurisdictions, paving the way for a more cohesive digital asset ecosystem.
