Past approaches to correcting for unit nonresponse in sample surveys by re-weighting the data assume that the problem is ignorable within arbitrary subgroups of the population. Theory and evidence suggest that this assumption is unlikely to hold, and that household characteristics such as income...

This paper provides welfare theoretic foundations for risk-adjusted capital flow regulations based on a standard class of macroeconomic models of financial crises that exhibit financial amplification dynamics. We show that during crisis episodes when such amplification effects are triggered,...

Advances in artificial intelligence and automation have the potential to be labor-saving and to increase inequality and poverty around the globe. They also give rise to winner-takes-all dynamics that advantage highly skilled individuals and countries that are at the forefront of technological...

Progress in artificial intelligence and related forms of automation technologies threatens to reverse the gains that developing countries and emerging markets have experienced from integrating into the world economy over the past half century, aggravating poverty and inequality. The new...

As artificial intelligence (AI) becomes more powerful and widespread, the AI alignment problem--how to ensure that AI systems pursue the goals that we want them to pursue--has garnered growing attention. This article distinguishes two types of alignment problems depending on whose goals we...

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...

The 1990s Sudden Stops in emerging markets were a harbinger for the 2008 global financial crisis. During Sudden Stops, countries lost access to credit, causing abrupt current account reversals, and suffered Great Recessions. This paper reviews a class of models that yields quantitative...

Financial regulation is often framed as a question of economic efficiency. This paper, by contrast, puts the distributive implications of financial regulation center stage. We develop a model in which the financial sector benefits from risk-taking by earning greater expected returns. However,...

Emerging market economies that borrow in foreign currency are prone to severe financial crises that involve financial amplification, i.e. a feedback loop of depreciating exchange rates, deteriorating balance sheets and declining aggregate demand. This is the first paper to show that such...
