Using examples drawn from two important papers in the recent literature on weak instruments, we demonstrate how observed experimental outcomes can be pro- foundly inuenced by the dierent conceptual frameworks underlying two exper- imental designs commonly employed when simulating simultaneous...

Poskitt and Skeels (2005) provide a new approximation to the sampling distribution of the IV estimator in a simultaneous equations model, the approximation is appropriate when the concentration parameter associated with the reduced form model is small. We present approximations to the sampling...

focus on the ability of the instrument set to predict a single endogenous regressor, even if there is more than one endogenous regressor in the equation of interest. We propose new measures of instrument relevance in the presence of multiple endogenous regressors, taking both univariate and...

Since 1986 dividend imputation has influenced the ex-dividend day behaviour of Australian share prices. Between 1 April 1986 and 30 May 2004 the Government of the day introduced six major legislative amendments intent on improving the efficiency of the dividend imputation system. This paper...

This paper explores sample size requirements for the estimation of SUR models by (two-stage) feasible generalized least squares, maximum likelihood and Bayesian methods. It is found that the sample size requirements presented in standard treatments of SUR models are incomplete and potentially...

Using examples drawn from two important papers in the recent literature on weak instruments, we demonstrate how observed experimental outcomes can be profoundly influenced by the different conceptual frameworks underlying two experimental designs commonly employed when simulating simultaneous...
