We study a growth model with an environmental asset which is a source of utility and an input to consumption and production. The stock of this asset follows its own ecological dynamics, which are affected by economic activity. We study the implications of an approach to ranking sequences of...

Green growth is about making growth resource-efficient, cleaner and more resilient without slowing it. This paper aims at clarifying this in an analytical framework and proposing foundations for green growth. This framework identifies channels through which green policies can potentially...

This paper proposes a new method to measure ethnolinguistic diversity and offers new results linking such diversity with a range of political economy outcomes -- civil conflict, redistribution, economic growth and the provision of public goods. We use linguistic trees, describing the...

In this paper I analyze the nature of external adjustments in current account surplus countries. I ask whether a realignment of world growth rates -- with Japan and Europe growing faster, and the U.S. growing more slowly -- is likely to solve the current situation of global imbalances. The main...

What accounts for differences in output per capita and total factor productivity (TFP) across countries? Empirical evidence points to resource misallocation across heterogeneous production units as an important factor. We study misallocation in a general equilibrium model of establishment...

Recent work emphasizes the primacy of differences in countries' colonially-bequeathed property rights and legal systems for explaining differences in their subsequent economic development. Barbados and Jamaica provide a striking counter example to this long-run view of income determination. Both...

We formulate a version of the growth model in which production is carried out by heterogeneous plants and calibrate it to US data. In the context of this model we argue that differences in the allocation of resources across heterogeneous plants may be an important factor in accounting for...

A Growing share of Emerging Markets (EMs) use hybrid versions of inflation targeting (IT) that differ from the IT regimes of OECD countries. Policy interest rates among commodity countries are impacted by real exchange rate and international reserves (IR) changes, aiming at stabilizing their...

We review the evidence that artificial intelligence (AI) is having a large effect on the economy. Across a variety of statistics—including robotics shipments, AI startups, and patent counts—there is evidence of a large increase in AI-related activity. We also review recent research in this...

This work explores how Argentina overcame the Great Depression and asks whether active macroeconomic interventions made any contribution to the recovery. In particular, we study Argentine macroeconomic policy as it deviated from gold-standard orthodoxy after the final suspension of...
