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 …

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...

Production Contracts and Farm Business Growth and Survival

Key, Nigel D. - 2010

In recent decades there has been a substantial increase in the scale of production and the use of production contracts in the hog sector. This paper explores empirically whether these two phenomena are related by examining whether the use of production contracts has allowed finish hog operations...

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...
