I found marketing to be highly descriptive and prescriptive, without much of a foundation in deep research. I brought in economics, organization theory, mathematics, and social psychology in my first edition of Marketing Management in 1967. Today Marketing Management is in its 15th edition and remains the world's leading textbook on marketing in MBA programs. Subsequently, I wrote two more textbooks, Principles of Marketing and Marketing: an Introduction.

We should tax every company's carbon footprint and the carbon footprint of every building and home, to incentivize people to reduce their carbon footprint.

The theory of marketing is solid but the practice of marketing leaves much to be desired.

When it comes to efficiency and effectiveness, I would always start with effectiveness. I am interested in achieving a certain outcome. Only secondarily do I worry about achieving it as efficiently as possible.

We need to put limits on how much an individual, group or business can spend on influencing an individual legislator or a whole set of legislators.

My parents, and their interest in making the world a better place for more people inspired me.

My primary early interest was in marketing and my aim was to improve its theories, methods and tools. Early on I pressed companies to adopt a consumer orientation and to be in the value creation business. I didn't pay much attention to the social responsibilities of business until later. Now I am pressing companies to address the triple bottom line: people, the planet, and profits. I found that companies were too much into short term profit maximization and they needed to invest more in sustainability thinking.
