The agency also declared virtual currencies to be commodities, introduced...

Joseph S. Nye Jr. is a Harvard University Distinguished Service Professor, Emeritus, and former Dean of Harvard's Kennedy School of Government. He has served as assistant secretary of defense for international security affairs, as chairman of the National Intelligence Council, and as deputy undersecretary of state for security assistance, science and technology.

His most recent book, published in 2024, is “A Life in the American Century.” His other book...

Ambassador Wendy Sherman, the 21st U.S. Deputy Secretary of State and the first woman in that position, has been a diplomat, businesswoman, professor, political strategist, author, and social worker. She served under three presidents and five secretaries of state, becoming known as a diplomat for hard conversations in hard places. As Deputy Secretary, she was the point person on China. While serving as Undersecretary for Political Affairs, Sherman led the U.S. negotiating team that reached an agreement on the Joint Comprehensive Plan of Action between the P5+1, the European Union and Iran.  And, as Counselor at the S...

With a Republican Congress apparently unwilling to check Trump’s power, many Americans fear a looming constitutional crisis and are looking to the federal courts to ride to the rescue. But political scientist and Harvard Kennedy School Professor Maya Sen, who studies the federal judiciary, says the cavalry probably isn’t coming. The Trump administration has seemingly defied judicial orders on deportations, withholding congressionally appropriated funds for federal programs, eliminating birthright citizenship, and other issues. Meanwhile, surrogates like Vice President J.D. Vance and billionaire Elon Musk have stated in social media posts that Trump is simply not bound by j...

Danielle Allen and Mark Fagan say that when tested, thoughtfully deployed, and regulated AI actually can help governments serve citizens better. Sure, there is no shortage of horror stories these days about the intersection of AI and government—from a municipal chatbot that told restaurant owners it was OK to serve food that had been gnawed by rodents to artificial intelligence police tools that misidentify suspects through faulty facial recognition. And now the Trump administration and Elon Musk’s so-called Department of Government Efficiency or DOGE say they are fast-tracking the use of AI to root out government waste and...

For market purists, any mention of the term industrial policy used to evoke visions of heavy-handed Soviet-style central planning, or the stifling state-centric protectionism employed by Latin American countries in the late 20th century. But that conversation turned dramatically over the last several years, as President Joe Biden’s signature legislative achievements like the CHIPS and Science Act and the Inflation Reduction Act showcased policies designed to influence and shape industries ranging from tech to pharma to green energy. My guest today, Harvard Kennedy School Professor Ricardo Hausmann, is the founder and director of the Growth Lab, which studies wa...

Ten years ago, political scientists Martin Gilens of Princeton and Benjamin Page of Northwestern took an extraordinary data set compiled by Gilens and a small army of researchers and set out to determine whether America could still credibly call itself a democracy. They used case studies 1,800 policy proposals over 30 years, tracking how they made their way through the political system and whose interests were served by outcomes. For small D democrats, the results were devastating. Political outcomes overwhelmingly favored very wealthy people, corporations, and business groups. The influence of ordinary citizens, meanwhile, was at a “non-significant, near-zero level.” America, they...

Alexander De Croo  became Belgium’s prime minister in October of 2020. It’s a relatively small country, with about 12 million inhabitants—slightly less than the city of Los Angeles—but it’s very much the face of Europe with the European Commission, the Council of the European Union, and NATO all calling Brussels home. Prime Minister De Croo, who saw the country through the COVID pandemic, says that the geopolitical and economic upheavals already being instigated by the “America first” ethos of President Donald Trump will present another stiff test for the leadership of not only his country but the EU. In this...

The warning lights are blinking for the world’s food supply. At least that’s what 150 Nobel Prize and World Food Prize laureates said in a recently-published open letter calling for a “moonshot” urgency effort to start the immediate ramping up of food production to meet the global demands of 9.7 billion people by 2050. Harvard Kennedy School economist Wolfram Schlenker, the new Ray A. Goldberg Professor of the Global Food System says doing that will require urgent policy changes and, in some cases, policy reversals to meet those goals against the headwinds of climate change. Even as crop yields are under st...

Jeremy Weinstein became the newest dean in the 88-year history of the Harvard Kennedy School this past June, arriving from Stanford University, where he was an award-winning scholar and the founding faculty director of the Stanford Impact Labs. The pursuit of deep scholarly curiosity and roll-up-your-sleeves impact has been a theme in his life and career, as well as an approach he intends to accelerate schoolwide at HKS under his leadership. Growing up, Weinstein experienced a family run-in with government policy gone horribly wrong—one that could have inspired a deep cynicism about the role of government in people’s li...

Turbocharged by the internet and mobile technology, legalized gambling has exploded across the globe, leaving behind ruined lives, broken families and financial hardships, and should now be classified as a major public health concern. A four-year study by a public health commission on gambling convened by The Lancet, the respected British journal of medicine, found that net global losses by gamblers could exceed $700 billion by the year 2028, and that 80% of countries now allow some form of legal gambling. But HKS Professor Malcolm Sparrow, a leading scholar on regulating societal harms, says that in reality the percentage of countries where...

The World Health Organization says smoking is the leading cause of global preventable death, killing up to 8 million people prematurely every year—far more than die in wars and conflicts. Yet the emotions evoked by national and international anti-smoking campaigns and the impact of those emotions has never been fully studied until now. HKS Professor Jennifer Lerner, a decision scientist who studies emotion, and Vaughan Rees, the director for the Center for Global Tobacco Control at the Harvard Chan School of Public Health, say their research involving actual smokers in the lab shows that sadness—the emotion most often evok...

Anti-LGBTQI+ (Lesbian, Gay, Bisexual, Transgender, Queer and Intersex) discrimination is on the rise, both in the United States, where hate crime statistics are climbing, and globally, with the increase in right-wing populist governments weaponizing public sentiment against marginalized people. But there are also rights advocates around the world pushing back, despite threats of physical harm, prosecution, and even death. The Carr Center for Human Rights Policy’s Timothy McCarthy and Diego Garcia Blum, who are leading a new program to support those advocates, joined host Ralph Ranalli to on the most recent episode of PolicyCast to talk about the proj...

America is in the grip of a severe housing crisis. Tenants have seen rents rise 26 percent while home prices have soared by 47 percent since early 2020. Before the pandemic, there were 20 US states considered affordable for housing. Now there are none. And 21 million households—including half of all renters—pay more than one-third of their income on housing. Harvard Kennedy School Associate Professor Justin de Benedictis-Kessner and former Burlington, Vermont Mayor Miro Weinberger say that’s because homebuilding hasn’t kept up with demand. They say housing production is mired in a thicket of restrictive zoning regulations and local politics, a “veto...

As Vice President Kamala Harris making a strong bid for the U.S. presidency, HKS Women and Public Policy Program Co-Director Hannah Riley Bowles says Harris is just one of many “path breakers” who have dramatically increased leadership opportunities for women. But she also says the reaction to Harris’ campaign in the media and the public conversation shows how the popular narrative about the efficacy of female leaders still lags behind the reality of what successful women are achieving. And she says that narrative also isn’t supported by research, including multiple studies showing that on average women are actually...

The attempted assassination of former President and candidate Donald Trump has catalyzed an important discussion about both actual violence and threats of violence against political candidates, office-holders, policymakers, election officials, and others whose efforts help make our democracy work. Harvard Kennedy School professors Erica Chenoweth and Archon Fung join host Ralph Ranalli to talk about political violence, what it is, what it isn’t, why it has grown, and—most importantly—strategies for mitigating it to ensure the health of democratic governance in the United States and beyond. The motivations and political leanings of the 20-year-old Pennsylvania man who shot a...

Populism—the political term that describes a group of self-described common people who oppose elite—has turned up in what for many is an unexpected place: the push for a worldwide transition to clean energy. Even though they’re vital to preventing the most catastrophic consequences of the manmade global climate crisis, clean energy measures are encountering pushback from multiple sources ranging from local citizens groups, to cost-conscious consumers, to self-styled conservationists, to right-wing politicians, and to corporate boardrooms. Harvard Kennedy School Professor Robert Z. Lawrence and Professor Dustin Tingley from Harvard’s Department of Government say a number of force...

Public policy has great power, both to improve people’s lives if it is planned and executed well and to cause significant suffering if it is not, says Harvard Kennedy School Dean Douglas Elmendorf, who will step back from his post this summer to rejoin the faculty. He joins PolicyCast host Ralph Ranalli in this episode to discuss the crucial role policy plays in everyday life, the often-imperfect ways it gets made, and the factors that shape it, including politics, values, education, and communication. He also addresses the issue of public distrust in policy advice and the vital role that...

HKS Senior Lecturer Linda Bilmes, an expert on public finance who has studied post-9/11 war costs for the past 20 years, says their staggering $5 trillion cost was enabled by what she calls “The Ghost Budget.” Using an unprecedented combination of borrowing, accounting tricks, and outsourcing, presidential administrations, Congress, and the Pentagon were able to circumvent traditional military budget processes in a way that kept war costs out of the public debate and resulted in trillions being spent with minimal oversight. The result: corporations and wealthy investors raking in huge profits, massive waste and fraud, and—combined with the Bush and Trump...

Harvard Kennedy School Professor Rana Mitter and Harvard Business School Associate Professor Meg Rithmire say that after decades of tremendous growth, an economically slowing China is the new normal. With a growing debt-to-GDP ratio, an aging population, a devastating real estate bubble, and a loss of confidence among both foreign investors and domestic consumers, Chinese President Xi Jinping and the Chinese Communist Party face a daunting array of thorny problems—including ones of their own making resulting from the One Child law policy and other home-grown policies. So how should the United States and other Western countries respond? Is it...

Former U.S. Ambassador to Israel Ed Djerejian says Israeli Prime Minister Yitzak Rabin once told him “There is no military solution to this conflict, only a political one.” Rabin was assassinated a few years later and today bullets are flying, bombs are falling, and 1,200 Israelis are dead after the Hamas terrorist attacks of October 7 and nearly 30,000 Gazans have been killed in the Israeli response. Yet Djerejain still believes that a breakthrough is possible even in the current moment, as horrible as it is. Djerejian, a senior fellow at Harvard Kennedy School’s Belfer Center for Science and International Relati...

As our discourse and our politics have become both more polarized and paralyzed, Harvard Kennedy School faculty members Erica Chenoweth and Julia Minson say we need to refocus on listening to understand, instead of talking to win. In mid-2022, the School launched the Candid and Constructive Conversations initiative, based on the idea that frank yet productive discussions over differences are not only vital to democracy and a functioning society, but that the ability to have them was also an essential skill for students, staff, and faculty in the Harvard community and beyond to learn. The effort—which uses techniques an...

Harvard Kennedy School Professor Kathryn Sikkink and former longtime Human Rights Watch executive director Kenneth Roth have spent years both studying the transformational effects of the Universal Declaration of Human Rights and have worked on the ground to make its vision of a more just, equal world a reality. On December 10th, the world celebrated not only the annual Human Rights Day, but also the 75th anniversary of the UDHR, which some historians and social scientists consider to be the greatest achievement in the history of humankind. It was the first time representatives of the world community declared that...

Legacy admissions, particularly at elite colleges and universities, were thrust into the spotlight this summer when the U.S. Supreme Court effectively ended affirmative action in admissions. The ruling raised many questions, and fortunately, Harvard Kennedy School professor David Deming and Harvard Economics Professor Raj Chetty were there with some important answers—having just wrapped up a 6-year study of the impact of legacy admissions at so-called “Ivy-plus” schools. Students spend years preparing to face judgment by colleges and universities as a worthy potential applicant. They strive for report cards filled with A’s in advanced placement courses. They voluntee...

Harvard Kennedy School faculty member Jorrit de Jong and Harvard Business School Professor Amy Edmondson say the big, intractable problems challenges facing city leaders today are too complex to be addressed by any one agency or government department. Complex challenges like the shortage of economic opportunity and affordable housing, homelessness, the effects of the climate crisis, crime—and can only be solved by multiple organizations working together. But that’s easier said than done. Bringing together government agencies, nonprofits, private business, academia, and the public into successful collaborations can be a huge challenge. Different people bring different agendas and goal...

Harvard Kennedy School Professor Todd Rogers and Lecturer in Public Policy Lauren Brodsky say trying too hard to sound intelligent—even when communicating complex or nuanced ideas—isn't a smart strategy. Because today’s overburdened information consumers are as much skimmers as readers, Rogers and Brodsky teach people how to put readers first and use tools like simplification, formatting, and storytelling for maximum engagement. They say you can have the most brilliant, well-researched ideas in the policy world, but you can’t communicate them, they’ll never reach the ultimate goal—making an impact. Rogers is the faculty chair of the Behav...

Dr. Rochelle Walensky, who served as CDC director from 2021 to 2023, calls the job “probably the hardest thing I will ever do.” But she also calls it “the honor of a lifetime.” When she was appointed by President Biden as the CDC’s 19th director, she was already used to politicized health care issues, having spent her formative years as a physician working on HIV and AIDS. But COVID thrust her into an unprecedented spotlight, forcing her to lead a demoralized agency through the challenges of implementing policy and informing the public while navigating a highly polarized and often toxic public sph...

Kennedy School Lecturer in Public Policy Bruce Schneier says Artificial Intelligence has the potential to transform the democratic process in ways that could be good, bad, and potentially mind-boggling. The important thing, he says, will be to use  regulation and other tools to make sure that AIs are working for us, and just not for Big Tech companies—a hard lesson we’ve already learned through our experience with social media. When ChatGPT and other generative AI tools were released to the public late last year, it was as if someone had opened the floodgates on a thousand urgent quest...

Harvard Kennedy School Professor Joseph Kalt and Megan Minoka Hill say the evidence is in: When Native nations make their own decisions about what development approaches to take, studies show they consistently out-perform external decision makers like the U.S. Department of Indian Affairs. Kalt and Hill say that’s why Harvard is going all in, recently changing the name of the Project on American Indian Economic Development to the Project on Indigenous Governance and Development—pushing the issue of governance to the forefront—and announcing an infusion of millions in funding.  When the project launched in the mid-1980s, the...

The history of American democracy has always been fraught when it comes to race. Yet no matter how elusive it may be, Harvard Kennedy School professors Khalil Gibran Muhammad and Archon Fung say true multiracial democracy not only remains a worthy goal, but achieving it is critically important to our collective future. From the earliest, formative days of the American political experiment, the creation of laws and political structures was often less about achieving some Platonic ideal of the perfect democratic system than it was about finding tenuous compromises between people and groups who had very different beliefs and...

As the U.S. prepares to spend hundreds of billions on new projects, HKS Professor Stephen Goldsmith says successfully upgrading our infrastructure will not only require spending all that money smartly, but spending it on infrastructure that is itself smart—full of sensors that can anticipate problems before they require costly repairs and that serve multiple functions instead of just one. With the passage of 2021’s Bipartisan Infrastructure Investment and Jobs Act and the 2022’s Inflation Reduction Act, the federal government has ushered in levels of infrastructure spending we haven’t seen since the days of President Dwight Eisenhower. Between...

Harvard Kennedy School Professor Gordon Hanson and Harvard Vice Provost for Climate and Sustainability James Stock say an important part of the green energy transition will be mitigating its effects on employment, both in the United States and overseas. Talking about the clean energy transition can conjure up images of commuters using sleek electric trains and electric cars powered by the sun and wind, and of workers with good-paying jobs installing the infrastructure of the future. But the outlook for communities that are economically tied to the fossil fuel economy that will be left behind isn’t quite as su...

When it comes to the climate crisis, there’s barely a day that goes by when we don’t hear about the impending effects of rising sea levels and storm-driven tides. But Harvard professors Jaqueline Bhabha and Hannah Teicher say there’s another rising tide that’s not getting as much attention, despite its potential to reshape our world. It’s the wave of climate migrants—people who have been and will be driven from their homes by rising seas, extreme heat, catastrophic weather, and climate-related famine and economic hardship. Some will try to relocate within their home countries, others acros...

Harvard Kennedy School professors Nancy Gibbs and Tom Patterson say local news is civic infrastructure. And it's crumbling. Like bridges, local news organizations use facts to help people connect with each other over the chasm of partisan political divides. People need reliable information to make important decisions about their lives—Where should I send my child to school? Who should I vote for? Should I buy a bigger house or a new car?—just as much as they need breathable air, clean water, and safe roads. Unfortunately, internet-driven market forces have cut traditional sources of revenue by 80 percent, and vult...

Harvard Kennedy School Professor Robert Stavins and Professor Daniel Jacob of Harvard’s School of Engineering and Applied Sciences are at the forefront of new efforts to monitor and control methane, a potent greenhouse gas. It used to seem like methane wasn't such a big deal. It was that other climate gas, the one that was the butt of cow flatulence jokes and that only stayed in the atmosphere for a decade or so. But since important global warming targets are now just 7 years away and science has developed a better understanding of both methane’s pervasiveness and its pote...

Economist and Harvard Kennedy School Professor Joe Aldy says  possibly the most complex—and one of the most existentially important—problems facing humanity is how to pull out the roots of fossil fuel infrastructure that are so deeply embedded in the global economy. The work is complex and the scale is immense; In fact it’s been said that transitioning the global economy from fossil fuels to sustainable sources will require the largest reallocation of capital in human history. Meanwhile Russia's invasion of Ukraine and its willingness to weaponize oil and natural gas distribution was a sign to many that th...

Matt Andrews, the faculty director of the Building State Capability program at Harvard Kennedy School, says the reasons why African nations haven’t done better at soccer’s world championships have a lot in common with why much of the continent’s economic promise has also gone unfulfilled. The World Cup, the biggest championship in soccer—or football, depending on where you are from—is currently underway and it's one of the two most-watched sporting events on the planet, the other being the Olympic Games. Yet even though it’s a world-wide event, the list of World Cup champions is dominated...
