Growing Out of Inequality

Income inequality has been increasing in most major economies – and in many of them, it has been increasing significantly. But the typical approach to tackling the problem – redistributive tax-and-transfer fiscal policies – can be controversial and divisive, owing to perceived tradeoffs between economic growth and greater equality.

WASHINGTON, DC – Income inequality has been increasing in most major economies – and in many of them, it has been increasing significantly. This is a cause for growing concern, and rightly so: inequality not only can undermine an economy’s long-term growth prospects; it can restrain growth in the short term by depressing aggregate demand.

The typical approach to tackling inequality – redistributive tax-and-transfer fiscal policies – can be controversial and divisive, owing to perceived tradeoffs between economic growth and greater equality. The result is usually heated debate and passionate rhetoric, but little concrete action. Politicians are especially prone to this dynamic – as evidenced by much of the conversation about inequality in the ongoing presidential election campaign in the United States.

There is a better way, one that is less controversial and politically more amenable to action: putting in place reforms that promote strong, inclusive growth that by its nature reduces inequality. This approach focuses on reducing inequalities of opportunity and broadening the base of participants in the growth process, thereby ensuring that more people benefit from it. Politicians who champion this approach may find it easier to build winning coalitions to enact it.

    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.
