Population growth has declined markedly in almost all major economies since the 1970s. We argue this trend has … important consequences for the process of firm dynamics and aggregate growth. We study a rich semi-endogenous growth model of … firm dynamics, and show analytically that a decline in population growth reduces creative destruction, increases average …

aggregate economic output. We apply it to estimate and compare the projected effects of climate change and population growth … over the course of the 21st century, by country and globally. We find that standard population growth projections imply … population impacts are correlated across countries: climate change and population growth will have their most damaging effects in …

At the heart of this … debate is the future path of both greenhouse gas emissions and economic development among the nations. We use global panel … data to estimate the relationship between per capita income and carbon dioxide emissions, and then use the estimated …

Fears that globalization necessarily hurts the environment are not well-founded. A survey reveals little statistical … measures of air pollution such as SO2 concentrations. Perceptions that WTO panel rulings have interfered with the ability of … borders. Global externalities include climate change and ozone depletion. Economic growth alone will not address such problems …

In this paper, we develop a methodology for estimating marginal emissions of electricity demand that vary by location …). The CO2 emissions per mile from driving PEVs are less than those from driving a hybrid car in the western United States … emissions per mile than the average car currently on the road. Underlying many of our results is a fundamental tension between …

This paper provides the first estimates of within-industry heterogeneity in energy and CO2 productivity for the entire … U.S. manufacturing sector. We measure energy and CO2 productivity as output per dollar energy input or per ton CO2 … emitted. Three findings emerge. First, within narrowly defined industries, heterogeneity in energy and CO2 productivity across …
