The Economics and Politics
of Greenhouse Gas Abatement


Kinntel NBER Sequence.01

There is broad consensus among economists that the most efficient way to reduce greenhouse gases is to put a price on carbon emissions, according to Christopher Knittel of MIT, a research associate in the NBER’s Environment and Energy Economics Program. So why does government policy often rely on other strategies, such as requiring use of biofuels. Knittel discusses research on the costs and benefits of such strategies in the video above. A selection of studies in this area may be found on the NBER Research on Energy Issues page.

The Demand for Bad Policy
When Voters Underappreciate Equilibrium Effects

Voters often underappreciate how new policies can change behavior of individuals and firms. This biases them towards policy changes that create direct benefits, even if the changes are not beneficial in the longer run, according to new research by Ernesto Dal Bó, Pedro Dal Bó, and Erik Eyster show.

Estimating Economic Benefits of the Shale Revolution

Estimates by Erik Gilje, Robert Ready, and Nikolai Roussanov imply that announcements of major shale oil-related technology innovations have added $3.5 trillion to aggregate U.S. equity values since 2012. Exposure to shale oil technology also has significant explanatory power for the cross-section of employment growth rates of U.S. industries over this period.

The Fading American Dream:
Trends in Absolute Income Mobility Since 1940

Rates of absolute mobility in the United States – the probability that a child will have higher earnings at a given age than his or her parents at the same age -- have fallen from approximately 90 percent for children born in 1940 to 50 percent for those born in the 1980s, research by Raj Chetty, David Grusky, Maximilian Hell, Nathaniel Hendren, Robert Manduca, and Jimmy Narang shows.

Is American Entrepreneurship in Crisis?
An NBER Conference Explores the Issue

Entrepreneurship is an important contributor to productivity growth in the American economy, and there is currently concern that American entrepreneurship is in serious decline. Participants in an NBER conference this autumn, convened with the support of the Ewing Marion Kauffman Foundation explored the measurement of entrepreneurial activity and the factors that affect it. They found that while the number of new firms has declined in recent years, the growth potential of the firms that are started has not; it actually has risen since 2010. Researchers also reported that labor productivity grows more rapidly at young firms than at their more established counterparts, and investigated how a number of public policies, such as state corporate income taxes and minimum wages, affect the rate of start-up activity.

Economic Gap between Black Men and Whites
Has Narrowed at the Top, but Nowhere Else




The income gap between black men and white men, a longtime reality in the U.S. labor market, narrowed sharply between 1940 and 1970 but has been largely stable ever since, according to research summarized in the January issue of The NBER Digest. But blacks near the top of the economic ladder have continued to make gains. Also featured in the January Digest are studies of the efficacy of rewarding donors in order to induce charitable giving, the comparative effects of taxes and government spending on economic output, the phenomenon of bias among ride-sharing drivers, the effects of online competition on brick-and-mortar schools, and the early success of an online master’s in computer science program at the Georgia Institute of Technology.

The Program on Children




Public programs for children and youth have expanded rapidly in recent decades, and so have the volume and scope of research into these programs' effectiveness. Janet Currie of Princeton University and Anna Aizer of Brown University, codirectors of the NBER's Program on Children, provide a broad overview of this work in the new edition of The NBER Reporter. Also featured in this issue of the quarterly are articles by NBER-affiliated economists on research into the forces of agglomeration and dispersion, income risk over the life cycle and the business cycle, effects of housing prices on aggregate economic activity, and accountability and measurement of ability among teachers.

Long-Term Care Hospitals
Discharge Patients Strategically




Long-term care hospitals are reimbursed with a lump sum payment after treating a patient a specified number of days, with smaller reimbursements before that. A study in the most recent edition of The NBER Bulletin on Aging and Health finds that these hospitals discharged patients after the lump sum payment day with much higher frequency than before the two-tiered payment system was put in place. This issue also features research examining how raising the early retirement age impacts retirement decisions in Austria and how reductions in child blood lead levels improve test scores.
