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.

Disappearing Routine Jobs: Who, How, and Why?

The deterioration of employment in middle-wage, routine occupations in the United States in the last 35 years has been driven primarily by a decline in the propensity to work in routine jobs among individuals from a small set of demographic groups, according to a study by Guido Matias Cortes, Nir Jaimovich, and Henry E. Siu. Advances in automation technology account for a relatively small portion of this employment decline.

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.

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.
