Geopolitics are no longer a tailwind for businesses today, opening markets and boosting global trade. Instead, argues ESSEC Business School associate professor Srividya Jandhyala, rising national security concerns and protectionist economic policies have created a headwind for many organizations, and that's changing how executives need to operate. She explains what’s changed in the global balance of power, how it's affecting even small to medium-sized companies and unexpected industries —from shrimp farming to fast fashion -- and why leaders need new talent and risk management strategies to adapt. Jandhyala is the author of the book The Great Disruption.

It isn't always easy to feel like you can have it all: career, family, hobbies and inner peace. Harvard professor Arthur C. Brooks studies happiness and says it is a direction, not a destination. Brooks believes happiness is especially important for leaders, as the higher you climb the more stressful the job can get - and the wider impact you can have on others. Live in conversation at Harvard Business School's Klarman Hall, he speaks with IdeaCast host and HBR editor at large Adi Ignatius about the importance of empathy and having a greater purpose in your life, not just in your career. Brooks is author of the book The Happiness Files: Insights on Work and Life.

When Wikipedia was founded in 2001, the idea that people around the world could come together to create an accurate online encyclopedia covering virtually any topic seemed far-fetched. But today many people see the website as a trusted source of well-curated and -cited information. That's because of careful decisions that its leaders made about how to operate. Cofounder Jimmy Wales explains how introducing a simple purpose, insisting on certain rules of engagement, and other strategies helped the organization to build trust with contributors and users -- and maintain it even in a world bombarded by misinformation. Wales is the author of The Seven Rules of Trust: A Blueprint for Building Things That Last.

Wilkins is author of the HBR article "The Hidden Beliefs That Hold Leaders Back" and the book Leadership Unblocked: Break Through the Beliefs That Limit Your Potential.

When it first came out in 2005, Freakonomics unearthed the hidden side to everything, helping bring behavioral economics to the forefront of popular culture.
