Dooley et al (2003, 2004a,b,c) argue that China seeks to raise urban employment by 10-12 million persons per year, with about 30% of that coming from export growth. In fact, total employment increased by 7.5-8 million per year over 1997-2005. We estimate that export growth over 1997-2002...

The confluence of three trends in the U.S. residential housing market---rising home prices, declining interest rates, and near-frictionless refinancing opportunities---led to vastly increased systemic risk in the financial system. Individually, each of these trends is benign, but when they occur...

The adoption and diffusion of inputs in the production network is at the heart of technological progress. What determines which inputs are initially considered and eventually adopted by innovators? We examine the evolution of input linkages from a network perspective, starting from a stylized...

We provide a general framework for the study of cascade effects created by interconnections between sectors, firms or financial institutions. Focusing on a multi sector economy linked through a supply network, we show how structural properties of the supply network determine both whether...

We document that even though the normal distribution is a good approximation to the nature of aggregate fluctuations, it severely underpredicts the frequency of large economic downturns. We then provide a model that can explain these facts simultaneously. Our model show that the propagation of...

This paper shows that large economic downturns may result from the propagation of microeconomic shocks over the input-output linkages across different firms or sectors within the economy. Building on the framework of Acemoglu et al. (2012), we argue that the economy's input-output structure can...

A statistical agency faces several challenges in building Productivity Accounts. What started out as a request for simple ratios of output to employment has moved to a demand for multifactor (total factor) productivity measures that take into account both labor and capital inputs, the...

The integration of the annual I-O accounts with the GDP-by-industry accounts is the most recent in a series of improvements to the industry accounts provided by the BEA in recent years. BEA prepares two sets of national industry accounts: The I-O accounts, which consist of the benchmark I-O...

The Urban Heat Island (UHI) provides direct evidence of how human activities contribute to a feedback loop that can result in multiple changes in ecosystem services by creating localized warming as well as differences in vegetated landscapes in areas surrounding the urban core. This paper...

Urban ecologists have extended the bounds of this field to incorporate both the effects of human activities on ecological processes (e.g., humans as generators of disturbances), and the ways in which the structures, functions, and processes of urban ecosystems, and human alterations to them, in...
