Clinical and Cost Consequences of Non-Adherence in the End-Stage Renal Disease Population.
Chuang, Chien-Chia - 2011
Results from this study indicate that non-adherence in hemodialysis (HD) sessions marginally affects health care costs … impacts of non-adherence in HD sessions on health care costs and kidney transplantation failure, and uses a conventional non …, consistent across three different regression estimations: OLS, 2SLS, and the log-linear regression. (2) The OLS estimation is …

CAUSAL EFFECT ESTIMATION UNDER LINEAR AND LOG-LINEAR STRUCTURAL NESTED MEAN MODELS IN THE PRESENCE OF UNMEASURED CONFOUNDING
Wang, Chia-Hao - 2010
analyses are biased due to unmeasured confounding. The instrumental variables (IV; Angrist et al., 1996) and G-estimation … investigate the validity of these IV methods for estimation under a log-linear SNMM. The results show that the IV estimators are … biased in the presence of unmeasured confounding. Therefore, we consider the G-estimation approach as an alternative solution …

Understanding the relationship between founder-CEOs and firm performance
Adams, Renee; Heitor, Almeida; Ferreira, Daniel - 2009
We use instrumental variables methods to disentangle the effect of founder–CEOs on performance from the effect of performance on founder–CEO status. Our instruments for founder–CEO status are the proportion of the firm's founders that are dead and the number of people who founded the...

Accrual Noise Ratio as a Measure of Accrual Reliability
Njoroge, Kenneth - 2009
I develop an empirical model that estimates a firm-specific accrual noise ratio (ANR), an operational and statistically grounded measure of accrual reliability, and test the measure's construct validity. The model allows accrual reliability to vary across firms, which is particularly important...

Solving and Testing for Regressor-Error (in)Dependence When no Instrumental Variables are Available: With New Evidence for the Effect of Education on Income
Ebbes, Peter; Wedel, Michel; Böckenholt, Ulf; … - 2005
This paper has two main contributions. Firstly, we introduce a new approach, the latent instrumental variables (LIV) method, to estimate regression coefficients consistently in a simple linear regression model where regressor-error correlations (endogeneity) are likely to be present. The LIV...
