Therefore, to remove the effects of time-invariant unobserved characteristics that potentially affect both training participation and wages, we exploit the longitudinal structure of the SLID data by implementing difference-in-differences matching estimators (Heckman et al. 1998).
We implemented another difference-in-differences analysis using a different sample window, with the pre-ban period ranging from October 2010 to June 2011, and post-ban from October 2011 to June 2012 (see Supporting information Table S6).
Rather than seek covariates that might lower the biased "VE" line in Figure 5 and keep it flat at zero outside of flu season, we implemented a difference-in-differences approach: We traced the trajectory of the bias over time and compared the vaccination-mortality association inside flu season with that outside of flu season.
However, when expected punishment was not implemented, individual differences in punishment sensitivity, specifically in BIS-anxiety, were related to fewer contributions (increased free riding) as compared to the situation when punishment was not implemented.
Using the Simulink interface of user defined S-functions we implemented the difference equation formulation of the stem cell model as a Matlab S-function.
We implement a difference-in-differences methodology to construct appropriate counterfactuals for the covered provinces.
Using accounting data on French innovative manufacturing firms, we implement appropriate difference-in-difference estimation techniques associated with a matching propensity score procedure.
We exploit the availability of a rich, relevant set of socio-demographic and labor-market characteristics for a large set of workers to implement semiparametric difference-in-differences matching models.
This data allows us to implement a difference-in-differences (DiD) identification strategy, since SSS details were announced in end-Mar 2016 and payouts were disbursed from end-Jul 2016 onwards.
We will implement a difference-in-difference analytic approach to evaluate pre-post APM changes between intervention and control groups, including: 1) clinic-level outcomes, 2) patient-level clinical outcomes, and 3) patient-level econometric outcomes.
