What Can Undermine a Carbon Tax?
Several countries have implemented a carbon tax or cap-and-trade system to establish high carbon prices and create a disincentive for the use of fossil fuels. Essentially, the tax encourages firms to substitute toward low carbon emission energy. Costs also rise for firms down the supply chain that use production inputs with high-emission content, so the total impact of a carbon tax can be large. In practice, however, firms also have an incentive to find an offset to a carbon tax. In this post, based on our recent work, we present evidence of one such adaptation strategy. We show that French firms increased their imports of high-emission inputs from suppliers outside the European Union’s cap-and-trade system, known as the EU Emissions Trading System (EU ETS), reducing the effectiveness of this approach to cutting carbon emissions—an adaptation strategy that leads to “carbon leakage.” To help stop this leakage, the EU is implementing a “carbon tariff” in 2026, which is the topic of a companion post.

Which Entrepreneurs Boost Productivity?
Why do some entrepreneurs drive economic growth while others do not? This piece discusses new work that studies entrepreneurs using a comprehensive dataset from Denmark. We study who becomes an entrepreneur, along with their hiring and business decisions, and find that a distinct minority are “transformative.” These individuals, who generate disproportionate productivity gains, tend to have high IQ scores, be well-educated, and hire technical (R&D) workers. The data support the idea of productivity growth being driven by the symbiotic relationship between transformative entrepreneurs and R&D workers. For policymakers, the lesson is that when an economy has more R&D workers and transformative entrepreneurs, they sustain higher long-run productivity growth.

Tariffs, Trade, and Tumbling Credit Scores: The Top 5 LSE Posts of 2025
Each year brings a new set of economic challenges: In 2025, major areas of focus included tariffs and trade tensions, as well as the financial pressures facing younger adults. New York Fed economists contributed insightful research on both topics—and readers took notice. In fact, all five of the year’s most-read posts on Liberty Street Economics analyzed aspects of these issues. Read on to see how the restoration of student loan data to credit reports affected borrowers’ credit scores, whether the costs of a college degree are still worth it, how businesses are responding to higher tariffs, and why the U.S. runs a trade deficit.

A New Public Data Source: Call Reports from 1959 to 2025
Call Reports are regulatory filings in which commercial banks report their assets, liabilities, income, and other information. They are one of the most-used data sources in banking and finance. In this post, we describe a new dataset made available on the Federal Reserve Bank of New York’s website that contains time-consistent balance sheets and income statements for commercial banks in the United States from 1959 to 2025.

Letters of Recommendation in the PhD Job Market: Lessons from Specialized Banks
Banks must extract useful signals of a potential borrower’s quality from a large set of possibly informative characteristics when making lending decisions. A model that speaks to how banks specialize in lending to an industry in order to better extract signals from data, can potentially be applied to a number of real-world scenarios. In this post, we apply lessons from such a model to a topic of timely relevance in economics: job market recommendation letters. Institutions looking to hire new economists must evaluate PhD applicants based on limited and often noisy signals of future performance, including letters of recommendation from these applicants’ advisors or co-authors. Using insights from our model, we argue that the value of these letters depends on who reads them.

Designing Bank Regulation with Accounting Discretion
Why does the banking industry remain prone to large and costly disruptions despite being so heavily regulated? Is there a need for more regulation, less regulation, or simply different regulation? Our recent Staff Report combines insights from academic research in economics, finance, and accounting to provide a deeper understanding of the challenges involved in designing and implementing bank regulation, as well as opportunities for future exploration. This post focuses on the regulation of bank capital, but the ideas are applicable more broadly.

Banks Develop a Nonbank Footprint to Better Manage Liquidity Needs
In a previous post, we documented how, over the past five decades, the typical U.S. bank has evolved from an entity mainly focused on deposit taking and loan making to a more diversified conglomerate also incorporating a variety of nonbank activities. In this post, we show that an important driver of the evolution of this new organizational form is the desire of banks to efficiently manage liquidity needs.
U.S. Banks Have Developed a Significant Nonbank Footprint
In light of the rapid growth of nonbank financial institutions (NBFIs), many have argued that bank-led financial intermediation is on the decline, based on the traditional notion that banks operate to take in deposits and make loans. However, we argue that deposit-taking and loan-making have not accurately characterized U.S. banking operations in recent decades. Instead, as we propose in this post, absent regulatory restrictions, banks naturally expand their boundaries to include NBFI subsidiaries. A significant component of the growth of NBFIs has in fact taken place inside the boundaries of banking firms.

How Has Treasury Market Liquidity Fared in 2025?
In 2025, the Federal Reserve has cut interest rates, trade policy has shifted abruptly, and economic policy uncertainty has increased. How have these developments affected the functioning of the key U.S. Treasury securities market? In this post, we return to some familiar metrics to assess the recent behavior of Treasury market liquidity. We find that liquidity briefly worsened around the April 2025 tariff announcements but that its relation to Treasury volatility has been similar to what it was in the past.

Banking System Vulnerability: 2025 Update
As in previous years, we provide in this post an update on the vulnerability of the U.S. banking system based on four analytical models that capture different aspects of this vulnerability. We use data through 2025:Q2 for our analysis, and also discuss how the vulnerability measures have changed since our last update one year ago.
