    We perform a multimodel detection and attribution study with climate model simulation output and satellite-based measurements of tropospheric and stratospheric temperature change. We use simulation output from 20 climate ...
  • Schiller, Peter H. (National Academy of Sciences (U.S.), 2010-08)
    In the retina, several parallel channels originate that extract different attributes from the visual scene. This review describes how these channels arise and what their functions are. Following the introduction four ...
  • Loiseau, Patrick; Schwartz, Galina; Musacchio, John; Amin, Saurabh; Sastry, S. Shankar (Institute of Electrical and Electronics Engineers (IEEE), 2014-04)
    Mobile data traffic has been steadily rising in the past years. This has generated a significant interest in the deployment of incentive mechanisms to reduce peak-time congestion. Typically, the design of these mechanisms ...
  • Pierre, Azoulay; Graff Zivin, Joshua S.; Gustavo, Manso (Rand Corporation, 2011-09)
    Despite its presumed role as an engine of economic growth, we know surprisingly little about the drivers of scientific creativity. We exploit key differences across funding streams within the academic life sciences to ...
  • Angrist, Joshua; Lang, Daniel; Oreopoulos, Philip (American Economic Association, 2009-01)
    Many North American college students have trouble satisfying degree requirements in a timely manner. This paper reports on a randomized field experiment involving two strategies designed to improve academic performance ...
  • Kojima, Fuhito; Pathak, Parag (American Economic Association, 2009-06)
    A number of labor markets and student placement systems can be modeled as many-to-one matching markets. We analyze the scope for manipulation in many-to-one matching markets under the student-optimal stable mechanism when ...
  • Loiseau, Patrick; Schwartz, Galina; Musacchio, John; Amin, Saurabh (Institute of Electrical and Electronics Engineers (IEEE), 2012-01)
    The Internet is plagued with congestion problems of growing severity which are worst at peak periods. In this paper, we compare two schemes that incentivize users to shift part of their usage from the peak-time to the ...
  • Duflo, Esther; Hanna, Rema; Ryan, Stephen (American Economic Association, 2012-06)
    We use a randomized experiment and a structural model to test whether monitoring and financial incentives can reduce teacher absence and increase learning in India. In treatment schools, teachers' attendance was monitored ...
