Dealing with femtorisks in international relations
(National Academy of Sciences (U.S.), 2014-12)The contemporary global community is increasingly interdependent and confronted with systemic risks posed by the actions and interactions of actors existing beneath the level of formal institutions, often operating outside ... -
Deals that start when you sign them
(Cambridge University Press (CUP), 2022)<jats:title>Abstract</jats:title><jats:p>This essay explores six sentences from Oliver Williamson – five providing context and the sixth the central topic. Decades ago, Williamson asserted that: (a) ‘substantially the same ... -
The Death Effect of Severe Climate Variability
(Elsevier B.V., 2013-01)Using data for all 2,454 municipalities of Mexico for the period 1980-2010, this paper analyzes the relationship between exposure to extreme temperatures and mortality rates. I find that severe heat increases mortality, ... -
Death of the salesman but not the sales force: how interested promotion skews scientific valuation
(University of Chicago Press, 2019-11)Whereas research has demonstrated how social cues appearing as disinterested social validation can skew valuation processes, interested promotion may be at least as important. This factor is examined here via the premature ... -
Debiased Machine Learning of Conditional Average Treatment Effects and Other Causal Functions
(Oxford University Press (OUP), 2021)<jats:title>Summary</jats:title> <jats:p>This paper provides estimation and inference methods for the best linear predictor (approximation) of a structural function, such as conditional average structural ... -
Debiased machine learning of global and local parameters using regularized Riesz representers
(Oxford University Press (OUP), 2022)<jats:title>Summary</jats:title> <jats:p>We provide adaptive inference methods, based on $\ell _1$ regularization, for regular (semiparametric) and nonregular (nonparametric) linear functionals of the ... -
Deblending random seismic sources via independent component analysis
(Society of Exploration Geophysicists, 2017-09)We consider the question of deblending for seismic shot records generated from simultaneous random sources at different locations, i.e., how to decompose them into isolated records involving one source at a time. As an ... -

Debt collateralization, capital structure, and maximal leverage
(Springer Berlin Heidelberg, 2019-08-19)Abstract We study the effects of allowing risky debt to be used as collateral in a general equilibrium model with heterogeneous agents and collateralized financial contracts. With debt collateralization, ... -

Debunking the Stereotype of the Lazy Welfare Recipient: Evidence from Cash Transfer Programs
(Oxford University Press, 2017-08)Targeted transfer programs for poor citizens have become increasingly common in the developing world. Yet, a common concern among policy-makers and citizens is that such programs tend to discourage work. We re-analyze the ... -
Decadal Attribution of Historic Temperature and Ocean Heat Content Change to Anthropogenic Emissions
(American Geophysical Union (AGU), 2020-02)We present an alternative method of calculating the historical effective radiative forcing using the observed temperature record and a kernel based on the 5th Climate Model Intercomparison Project (CMIP5) temperature ... -
The decadal mean ocean circulation and Sverdrup balance
(Journal of Marine Research/Yale, 2011-03)Elementary Sverdrup balance is tested in the context of the time-average of a 16-year duration time-varying ocean circulation estimate employing the great majority of global-scale data available between 1992 and 2007. The ... -
A decadal satellite analysis of the origins and impacts of smoke in Colorado
(Copernicus GmbH, 2013-08)We analyze the record of aerosol optical depth (AOD) measured by the MODerate resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite in combination with surface PM[subscript 2.5] to investigate the impact ... -
Decadal-Scale SST and Salinity Variations in the Central Tropical Pacific: Signatures of Natural and Anthropogenic Climate Change
(American Meteorological Society, 2011-06)Accurate projections of future temperature and precipitation patterns in many regions of the world depend on quantifying anthropogenic signatures in tropical Pacific climate against its rich background of natural variability. ... -
A Decade Of Timing An Accretion-Powered Millisecond Pulsar: The Continuing Spin Down And Orbital Evolution Of Sax J1808.4–3658
(IOP Publishing, 2009-08)The Rossi X-ray Timing Explorer has observed five outbursts from the transient 2.5 ms accretion-powered pulsar SAX J1808.4–3658 during 1998-2008. We present a pulse timing study of the most recent outburst and compare it ... -
A DECADE-BASELINE STUDY OF THE PLASMA STATES OF EJECTA KNOTS IN CASSIOPEIA A
(IOP Publishing, 2013-05)We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the kinematic and thermal state of the ... -
Decarbonization of the Cargo Shipping Fleet
(The Society of Naval Architects and Marine Engineers, 2022-06-29)Abstract In an effort to combat climate change, the International Maritime Organization (IMO) has set ambitious goals for the reduction of greenhouse gas emissions from ships, with a target of at least a 50% ... -
The decay of debris disks around solar-type stars
(IOP Publishing, 2014-03)We present a Spitzer MIPS study of the decay of debris disk excesses at 24 and 70 μm for 255 stars of types F4-K2. We have used multiple tests, including consistency between chromospheric and X-ray activity and placement ...
