The Evian Group @ IMD welcomed Nobel Laureate Michael Spence for an evening discussion about his recently released book, The Next Convergence. IMD alumni, Corporate Learning Network members and PED program participants joined The Evian Group network to learn from Spence’s farreaching and incisive perspectives on “the future of economic growth in a multispeed world.” The following morning, Spence presented and met with IMD MBA students as part of The Evian Group’s Annual MBA Roundtable, which this year focused on “equity and sustainability” and engaged a host of world-renowned experts to discuss the challenges globalization presents, from poverty to gender to climate change.


In his opening remarks, IMD Professor Jean-Pierre Lehmann described Spence as a rare breed – a “modest economist” who has demonstrated that economics originated in moral philosophy, prior to its shift into a more mathematics-focused discipline. Among Spence’s many career accomplishments, Professor Lehmann detailed two that have distinguished him and provide a backdrop to his approach to world economics order in The Next Convergence.

The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, 2001

In 2001 the Royal Swedish Academy of Sciences awarded the Bank of Sweden’s Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel jointly to George A. Akerlof, University of California at Berkeley, A. Michael Spence, Stanford University, and Joseph E. Stiglitz, Columbia University, USA “for their analyses of markets with asymmetric information.” In summary, “this work defined how many markets are characterized by asymmetric information, i.e. one side of the market having better information than the other, e.g. borrowers knowing more than lenders about their repayment prospects, managers and boards knowing more than shareholders about the firm’s profitability, and prospective clients knowing more than insurance companies about their accident risk. Spence laid the foundation for a general theory of markets with asymmetric information, forming the core of modern information economics. He identified an important form of adjustment by individual market participants, where the better informed take costly actions in an attempt to improve their market outcomes by credibly transmitting information to the poorly informed. Spence demonstrated when such signaling will actually work.”1

Chair of The Commission on Growth and Development, 2006–2010

In 2006 the Commission on Growth and Development was formed to bring together leading practitioners across sectors – from government, business and policymaking – mostly from the developing world. The Commission’s goal was to understand the policies and strategies that enable rapid and sustained economic growth and poverty reduction. In The Growth Report: Strategies for Sustained Growth and Inclusive Development, the Commission was successful in detailing that fast, sustained growth is both possible and predictable.

Developing countries that combine the right approach (incentives, public investment and diversification) with strong leadership can and do leverage opportunities that the global economy affords. These findings laid the foundation for Spence’s book The Next Convergence: The Future of Economic Growth in a Multispeed World.

The Next Convergence? What is it?

The recent period of growth in developing countries has resulted in their convergence with established countries. Spence details how the global economy will evolve over the next fifty years, and puts into perspective how economic growth can be sustained in both advanced and developing countries, thus reshaping the world economy and favorably benefitting the many versus the few. Post World War II, a reversal of the past 200 years of divergence has occurred. The world is now almost midway through a century of convergence, and Spence provides a comprehensive “tour of critical parts of the world economy,” detailing the scale and complexity of this redefining period.

Where has growth been achieved?

Out of about 180 countries in the world, 13 have grown at an average rate of 7% or more for 25 years. While not a long list, this is a remarkable achievement that would not have been thought possible 50 years ago.

Needless to say, the scale and velocity of this growth have dramatic impact, especially on the poor. “Growth with a reasonably inclusive pattern of the distribution of benefits is a potent weapon in reducing poverty.”2

Why have these countries achieved sustained growth?

While Spence outlined a number of criteria, he profiled the following during his talk:

  1. Openness to the global economy
  2. Inclusiveness and equity
  3. Leadership, especially at the national level
Openness to the global economy – critical!

As Spence explained, there are “no barriers or market limits for a small, poor country.” When supported by flows in capital, transfers of knowledge and technology, a nation creates the capacity for growth. However, this is still only one of several requirements for creating and sustaining growth.

Inclusiveness and equity

This combination, according to Spence, is “not a nice add on, but inherently important to growth strategy. If you goof on this one, you won’t grow.” Inclusiveness in economics originated in India, but it is now broadly used and relates to how growth is distributed. The notion of inclusive growth is widely debated and a single definition does not exist. For Spence, it means “that people should not be left out or excluded from the opportunities created by growth, and there should be no limits to the amount of inequality in income and access to basic services that are tolerable.”3 In the absence of inclusiveness and in extremes of inequality, societal and political challenges to growth will emerge.


Spence stressed, “Having a vision and being able to build consensus is critical again.” Top leadership at the national level, who recognize that growth will take compromise and sacrifice, is key during the start-up phase. Once growth strategies begin to gain traction and lead to successes, effective governance and strong institutional infrastructures need to be built up over time. As this occurs, top leadership are on the hook, having to learn, make mistakes and evolve in a dynamic environment or trust and governance will erode quickly.

A Moral Community of Concern – Our Current Dilemma

In The Growth Report, Spence attempts to answer the key question: “Who do I care about? My immediate family, my extended family, neighborhood, region, the world?” In doing so, he examines the nature of equity and equality between nations, pinpointing both the philosophical and technical challenges arising from global policy instruments on responsibility.4

Convergence – “The rest of the world has joined the party!”

Having now reviewed what has passed, Spence turns his attention to the future. Will this fast growth continue and what is it reliant on? For the world economy to expand and grow in a more equitable way, he highlights three categories of concerns – instability and volatility, economy and demand, and the tension between nations and the globe (part to whole), especially as they relate to energy, environment, food and industrial composition. He illustrates these concerns by profiling three dominant economies – China, India and Brazil.

Spence then progresses through the consequential influencers to sustain growth, examining energy, climate change, information technology and global governance. In the end, the “long-term sustainability challenge” grabs significant real estate and focuses our attention on the global economy’s explosion – slated to triple in the next 25 years, concentrate in Asia and necessitate change in individual, national and global patterns, models and behaviors. Academic, business and political elites have lost their luster. Spence acknowledges the mistakes made and that these do not seem to have engendered a more humble response to what this problem-solving requires, leaving a void which is currently being filled by political battles over aspirations that are not shared.


Spence leaves us with a deeper understanding and optimistic perspective of some of the critical influences and requirements to achieve a better world order. He describes the world in which his grandchildren will live as one that is made up of countries with 85% to 90% of their population earning high incomes (vs. 15% to 20% currently) and based on innovation (vs. one based on past experience and outdated policies and tools).

This world may well be beyond our imagination now, but we should not be daunted by it. He challenges us and the next generation to rise to the long-term growth and sustainability challenge with the confidence that our ingenuity will prevail. He does not sugarcoat this message; instead, he prepares us for a long and bumpy ride.
