Tariffs are no longer simply a trade policy issue. They are becoming a significant challenge for businesses trying to manage costs, protect profits and remain competitive in an increasingly unpredictable global marketplace.

A recent Reuters Plus feature, Why Tariff Volatility Makes Pricing a Forever Process, produced for global consultancy Simon-Kucher, examines how rapidly changing tariffs are forcing companies to continuously reassess their pricing strategies and supply chains.

Among the experts featured is Anna Nagurney, Eugene M. Isenberg Chair in Integrative Studies at the Isenberg School of Management at the University of Massachusetts Amherst.

Nagurney, an internationally recognized expert in supply chain networks and disruption management, points to the extraordinary pace of trade policy changes. She estimates that U.S. tariff regulations changed approximately 50 times during 2025, creating uncertainty for manufacturers, wholesalers, retailers and consumers.

"The speed and uncertainty created a great deal of challenges for manufacturers, wholesalers, retailers and, of course, consumers."

Why Even Domestic Businesses Are Vulnerable

One of the article's central messages is that businesses do not have to import products directly to feel the impact of tariffs.

Higher costs can spread throughout interconnected supply chains, affecting suppliers, transportation networks and ultimately consumers.

Nagurney emphasizes the importance of viewing supply chains as networks rather than simple, linear systems. By identifying critical suppliers, examining vulnerabilities and preparing for potential disruptions, businesses can make better decisions before costs escalate.

She also cautions that smaller companies may struggle to absorb tariff-related increases without jeopardizing their financial stability.

As businesses face continued uncertainty, Nagurney can provide valuable perspective on how tariffs influence supply chains, consumer prices, business competitiveness and the broader economy.

An experienced commentator on global supply chain disruptions, Nagurney has provided analysis to major news organizations, including The New York Times, Associated Press, NPR, The Washington Post, The Boston Globe and The Wall Street Journal.

Are Small-Dollar Political Donations Making American Politics More Divisive?

Small-dollar political donations have long been celebrated as a way to reduce the influence of wealthy contributors and give ordinary Americans a greater voice in elections. But new research suggests that the growing influence of these donors may also be contributing to political polarization and rewarding candidates who generate attention rather than build consensus. In an article published in The Atlantic, titled Small-Dollar Campaign Donors Are Hurting the Political System, journalist Idrees Kahloon examines how the explosion of grassroots political fundraising has changed American campaigns, drawing attention to research challenging the assumption that small donations necessarily produce healthier democratic outcomes. Among the researchers examining this trend is Ray La Raja, professor of political science and co-director of the UMass Amherst Poll at the University of Massachusetts Amherst. View his profile La Raja is co-author, with Zachary Albert of Brandeis University, of the 2026 book Small Donors in US Politics: Myth and Reality, which examines who contributes to political campaigns, what motivates their donations and how their growing influence affects elections and political representation. Their research finds that small-dollar donors are often more politically engaged, more partisan and more ideologically committed than the average voter. While these contributions can broaden participation in campaign financing, they can also encourage candidates to pursue national attention and emotionally charged fundraising appeals rather than focus on local concerns or legislative compromise. The findings raise important questions about whether the growing influence of small donors is strengthening political representation or creating new incentives for polarization. The issue is particularly relevant ahead of the 2026 midterm elections, as candidates and political parties compete for campaign contributions in an increasingly nationalized fundraising environment. La Raja's work also examines the role of political parties in campaign finance and whether reforms designed to reduce the influence of large donors have produced unintended consequences. With campaign fundraising, political polarization and democratic accountability increasingly connected, La Raja offers journalists a research-based perspective on one of the less understood forces shaping American elections.

Does International Law Still Matter? UMass Amherst Expert Weighs In on Doha Debates

As wars, geopolitical tensions and questions about international accountability challenge the global order, an important debate is emerging: Does international law still matter when powerful countries can choose to ignore it? That question was at the center of a recent episode of Doha Debates, which brought together international experts to examine the effectiveness, legitimacy and future of international law. Among the featured panelists was Charli Carpenter, Professor of Political Science at the University of Massachusetts Amherst, who offered a perspective on why international law remains important, even when its rules are violated. The discussion also featured Balakrishnan Rajagopal of the Massachusetts Institute of Technology, Victor Gao of the Center for China and Globalization and political philosopher Curtis Yarvin. Carpenter challenged the notion that violations of international law necessarily demonstrate its failure. She pointed to the international agreements that make everyday global cooperation possible, from aviation safety to diplomacy, and argued that international legal frameworks have helped establish expectations for how countries conduct themselves. Charli Carpenter is a scholar of international relations whose research examines international law, human security, global norms and the role of advocacy networks in shaping international policy. View her profile She also emphasized that violations can sometimes strengthen international norms by prompting other countries and institutions to reaffirm their importance. "And I think it is a common myth that if an actor breaks a rule that necessarily weakens the rule. Sometimes that can be an impetus for others to defend and reaffirm the rule. And it's often the case that rule breakers don't undermine rules, they undermine themselves and their social standing in a community." The debate explored the role of the United Nations, the Geneva Conventions, the International Criminal Court and the challenges of holding powerful countries accountable. Carpenter also discussed research into international treaties and public attitudes toward nuclear weapons, explaining how international agreements can influence expectations and behavior even when major powers are not parties to them. As global conflicts continue to test international institutions, the discussion offers a timely examination of whether the international legal system needs reform, stronger enforcement or renewed political commitment. Watch the full Doha Debates discussion on YouTube to hear Carpenter and her fellow panelists explore the future of international law and the consequences of weakening global institutions.

Could a Supreme Court Power Play Backfire on Republicans?

With November's midterm elections approaching, Republicans may face a consequential decision: whether to confirm another conservative Supreme Court justice before potentially losing control of the Senate. In a new piece published October 14 in The Conversation, Paul M. Collins Jr., professor of legal studies and political science at the University of Massachusetts Amherst, examines how such a move could reshape the Supreme Court and intensify political divisions over the judiciary. Collins explains that if Democrats win control of the Senate, a retirement by conservative Justices Clarence Thomas or Samuel Alito before the new Congress takes office in January could give President Donald Trump an opportunity to appoint a fourth Supreme Court justice. While Republicans could potentially secure another conservative appointment, Collins argues the political consequences could extend well beyond the immediate confirmation battle. As Collins writes in The Conversation: If Alito or Thomas announced their retirement after the midterms, Republicans would have enough time to confirm a successor. The Senate has four and a half work weeks scheduled between Election Day and Jan. 3. Justice Amy Coney Barrett was confirmed less than a month after her nomination, making the timeline tight but doable. His analysis draws parallels to the contentious Supreme Court confirmation battles of 2016 and 2020, when Republicans blocked Merrick Garland's nomination before subsequently confirming Amy Coney Barrett shortly before a presidential election. Collins suggests another controversial confirmation could further undermine public confidence in the Supreme Court and strengthen calls for judicial reform, including expanding the number of justices. The stakes are significant. With lifetime appointments shaping constitutional interpretation for decades, the outcome could influence not only the Court's ideological direction but also the future of judicial independence and the relationship between Congress and the judiciary. Paul M. Collins, Jr. is a professor of legal studies and political science at the University of Massachusetts Amherst. His research focuses on understanding bias and inequality in the legal system, the selection and work of judges and social movement litigation. View his profile An established authority on Supreme Court nominations, Collins has researched judicial appointments, political influences on the courts and the confirmation process. He is co-author of Supreme Court Confirmation Hearings and Constitutional Change and Supreme Bias: Gender and Race in U.S. Supreme Court Confirmation Hearings. As the midterm elections approach, Collins can provide journalists with expert analysis of Supreme Court vacancies, Senate confirmation procedures, judicial politics and the potential long-term consequences of another contentious appointment.
