Saving Resources to Save Growth

Reconciling global economic growth, especially in developing countries, with the intensifying constraints on global supplies of energy, food, land, and water is the great question of our time. Only if the world cooperates on the research, development, demonstration, and diffusion of resource-saving technologies and renewable energy sources can we safeguard economic progress.

NEW YORK – Reconciling global economic growth, especially in developing countries, with the intensifying constraints on global supplies of energy, food, land, and water is the great question of our time. Commodity prices are soaring worldwide, not only for headline items like food and energy, but for metals, arable land, fresh water, and other crucial inputs to growth, because increased demand is pushing up against limited global supplies. Worldwide economic growth is already slowing under the pressures of $135-per-barrel oil and grain prices that have more than doubled in the past year.

A new global growth strategy is needed to maintain global economic progress. The basic issue is that the world economy is now so large that it is hitting against limits never before experienced.  There are 6.7 billion people, and the population continues to rise by around 75 million per year, notably in the world’s poorest countries. Annual output per person, adjusted for price levels in different parts of the world, averages around $10,000, implying total output of around $67 trillion.

There is, of course, an enormous gap between rich countries, at roughly $40,000 per person, and the poorest, at $1,000 per person or less. But many poor countries, most famously China and India, have achieved extraordinary economic growth in recent years by harnessing cutting-edge technologies. As a result, the world economy has been growing at around 5% per year in recent years. At that rate, the world economy would double in size in 14 years.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
