Survey incentives, survey effort, and survey costs [PDF]

open access: yesFinance and Economics Discussion Series, 2014
This paper uses the 2007 and 2010 waves of the Survey of Consumer Finances (SCF) to investigate how monetary incentives affect the time and effort that interviewers expend during the survey field period, and how these incentives affect effort expended by the survey respondent.

Parametrizing modified gravity for cosmological surveys [PDF]

open access: yes, 2017
One of the challenges in testing gravity with cosmology is the vast freedom opened when extending General Relativity. For linear perturbations, one solution consists in using the Effective Field Theory of Dark Energy (EFT of DE).
