Trump’s Ten Commandments: Strategic Lessons from the Trump Leadership Toolbox offers a provocative and penetrating look inside the mind of one of history’s most controversial leaders. Written by Jeffrey Sonnenfeld, celebrated Yale leadership scholar and advisor to five U.S. presidents, this book reveals the ten guiding principles—or “commandments”—that define Donald Trump’s decision-making across business, media, and politics.

Drawing from decades of personal interactions with Trump as advisor, critic, and confidant, Sonnenfeld moves beyond gossip and ideology to decode the predictable patterns behind Trump’s seemingly chaotic style. There are critiques and salutes through history of the impact of the imperial presidency but no existing current or past analysis of how such leadership operates until this deep dive into Trump’s toolkit. Sonnenfeld exposes how Trump’s playbook—built on domination, disruption, and relentless self-promotion—breaks every conventional rule of leadership yet often achieves results through sheer force of will.

From the boardroom to the Oval Office, Sonnenfeld distills lessons in power, persuasion, and performance—lessons that illuminate not only Trump’s successes and failures but also timeless truths about human ambition, influence, and control. Whether you admire or abhor him, understanding Trump’s Ten Commandments reveals how he built empires, dismantled institutions, and redefined leadership in his own image.

Part insider analysis, part leadership case study, Trump’s Ten Commandments helps readers grasp how Trump thinks, how he leads, and what his methods teach us—about both the dangers and the undeniable magnetism of power used without restraint.

For anyone seeking to understand America’s most unpredictable leader, this is the definitive guide to Trump’s strategy, psychology, and legacy.

This chapter reviews major theories of emotion and decision making, concentrating on developments within the disciplines of psychology, economics, and decision science. These theories naturally cluster into two sets of theories – one set that views emotional valence (i.e., positivity versus negativity) as the primary factor for predicting decision outcomes, and a second set of theories that views valence as one of multiple factors for making predictions. Often known as “emotion-specific models”, theories in this latter set propose that emotions of the same valence can have opposing (rather than similar) effects on certain decisions. After describing strengths and weaknesses of each approach, the chapter offers a review of the Emotion-Imbued Choice model (EIC) – a unified, meta-level model of emotion and decision making.

Operations research, originating during World War II, is the scientific study of operations aimed at improving decision-making and organizational performance. Initially focused on military logistics, its scope has expanded to address diverse operational problems in business, government, and non-profit sectors. These include scheduling, capacity planning, routing, and resource allocation. Through mathematical modeling and analysis, operations research seeks not just to describe but to optimize operations by aligning them with organizational goals such as maximizing profit, minimizing costs, or enhancing effectiveness. The field has evolved from simple problem identification to complex mathematical modeling, emphasizing the importance of framing the right problem within a well-understood system context. Applied operations research assumes that the identified problem can be modeled mathematically, that the models and assumptions are valid, and that organizational objectives and constraints are clearly defined and quantifiable. The ultimate aim is actionable recommendations that improve real-world decision-making. Grounded in the belief in mathematical rigor, operations research integrates objectives and constraints to deliver feasible solutions. By leveraging analytical tools, it supports better decision-making, ensuring that operations are not only efficient but also aligned with strategic priorities, making it a practical and impactful discipline across sectors.

Demand rebounded more rapidly than expected after the COVID pandemic. This interacted with a series of unprecedented supply-side shocks around the shutdown and reopening of economies, along with broad-based increases in commodity prices following the invasion of Ukraine. Inflation spiked to the highest level in decades. In response, central banks tightened monetary policy sharply. This book explores the commonalities and differences in countries’ strategies, as well as lessons for the next inflationary episode.

How to handle the ethical challenges raised by entrepreneurship education amid its explosive growth in colleges—from the perspective of an educator, administrator, investor, inventor, and former student entrepreneur.

Entrepreneurship is now everywhere on college campuses: from classes and contests to accelerators and incubators spread across diverse departments and programs. These activities cultivate tomorrow's Facebooks and Googles but can also put profit in conflict with pedagogy. Should faculty keep information about student start-ups confidential? Should universities, or educators personally, invest in student start-ups? Should educators adjudicate disputes between student founders? In The Ethics of Entrepreneurship Education, Kyle Jensen addresses these questions and many others.

This book fills a significant hole in the literature and helps readers think through the everyday ethical problems that arise in campus entrepreneurship. Jensen draws on economics literature, normative ethics, the wisdom of antiquity, and stories from his own wide-ranging experience to guide the discussion, while mixing in a good deal of wit and levity. It is an invaluable resource for all those involved in campus entrepreneurship, from university educators and administrators to students, mentors, investors, donors, and alumni.

Not one inch. With these words, Secretary of State James Baker proposed a hypothetical bargain to Soviet leader Mikhail Gorbachev after the fall of the Berlin Wall: if you let your part of Germany go, we will move NATO not one inch eastward. Controversy erupted almost immediately over this 1990 exchange—but more important was the decade to come, when the words took on new meaning. Gorbachev let his Germany go, but Washington rethought the bargain, not least after the Soviet Union’s own collapse in December 1991. Washington realized it could not just win big but win bigger. Not one inch of territory needed to be off limits to NATO.

On the thirtieth anniversary of the Soviet collapse, this book uses new evidence and interviews to show how, in the decade that culminated in Vladimir Putin’s rise to power, the United States and Russia undermined a potentially lasting partnership. Prize-winning historian M. E. Sarotte shows what went wrong.
