I grew up in a family in which political issues were often discussed, and debated intensely.

When you don't have equality of opportunity because you don't have equal access to education, it just seems so outrageous. It weakens our economy and leads to more inequality.

If there is a silver lining in the Trump cloud, it is a new sense of solidarity over core values such as tolerance and equality, sustained by awareness of the bigotry and misogyny, whether hidden or open, that Trump and his team embody.

The notion that every well educated person would have a mastery of at least the basic elements of the humanities, sciences, and social sciences is a far cry from the specialized education that most students today receive, particularly in the research universities.

By taxing CO2, firms and households would have an incentive to retrofit for the world of the future. The tax would also provide firms with incentives to innovate in ways that reduce energy usage and emissions - giving them a dynamic competitive advantage.

Technology has been advancing so fast that the number of jobs globally in manufacturing is declining. There is no way that Trump can bring significant numbers of manufacturing jobs back to the U.S.

What separates developing countries from developed countries is as much a gap in knowledge as a gap in resources.

With the election of Trump, America's soft power has taken a big hit. The United States has moved from a position of leadership in the creation of a rules-based international system to a position of leadership in its destruction and the creation of a regime of global protectionism. The damage will be long-lasting.

Globalization and trade liberalization were supposed to make us all better off through the mechanism of trickle-down economics. What we seemed to be seeing instead was trickle-up economics, accompanied by a destruction of democratic politics, as we moved ever closer to a system of 'one dollar, one vote' as opposed to 'one person, one vote.'

High levels of economic inequality lead to imbalances in political power, as those at the top use their economic weight to shape our politics in ways that give them more economic power.

Macroeconomic policy can never be devoid of politics: it involves fundamental trade-offs and affects different groups differently.
