“…The lower the QIC, the better fit the correlation structure reveals (Hin, Carey, & Wang, 2007;Pan, 2001). The QIC for the current analyses indicated that the AR1 (auto-regressive) structure is to be preferred (available upon request).…”

This paper experimentally studies the potential effect of works councils on managerial decision-making. Empirical evidence on the influence of works councils in organizations is still mixed. Therefore, this experimental study tries to gain more insights into the mechanisms that may underlie the impact of works council advice. First, we try to explain whether advice given by a works council influences the decision managers make. Second, we attempt to explain whether works councils delay the decision-making process. In order to answer these questions, we conducted experiments with undergraduate students, who played a two-player Prisoner's Dilemma price-setting game. One group received advice from a works council, whilst the other group did not. As expected, advice does have an influence on decision-making: receiving advice for setting a low price leads to a higher likelihood to set a low price as well, and receiving advice to set a high price leads to a high price decision. Female managers are more likely to take the works council advice into account. Subjects with an other-regarding orientation tend to choose a high price, even when they are advised to opt for a low price. Further, decisionmaking is not delayed by the advice, but there is an interaction effect with gender: female managers receiving advice tend to think longer about their decision.

“…In the past, different proposals were done to select the best correlation structure, including the Rotnitzky-Jewell's criterion (RJ(R)) [23] and the quasi-likelihood under the independence criterion (QIC(R)) [21]. Hin et al [11] conclude that none of these two methods can be regarded as a dominant criterion for working correlation selection in GEE. A data-driven selection procedure to identify an appropriate correlation structure seems to be still an open problem.…”

We aimed to study the excess health-care expenditures for persons with a known positive isolate of Streptococcus pneumoniae . The data set was compiled by linking the database of the largest Belgian Sickness Fund with data obtained from laboratories reporting pneumococcal isolates. We analyzed the age-specific per-patient cumulative costs over time, using generalized estimating equations (GEEs). The mean structure was described by fractional polynomials. The quasi-likelihood under the independence model criterion was used to compare different correlation structures. We show for all age groups that the health-care costs incurred by diagnosed pneumococcal patients are significantly larger than those incurred by undiagnosed matched persons. This is not only the case at the time of diagnosis but also long before and after the time of diagnosis. These findings can be informative for the current debate on unrelated costs in health economic evaluation, and GEEs could be used to estimate these costs for other diseases. Finally, these results can be used to inform policy on the expected budget impact of preventing pneumococcal infections.

The weighted generalized estimating equation (WGEE), an extension of the generalized estimating equation (GEE) method, is a method for analyzing incomplete longitudinal data. An inappropriate specification of the working correlation structure results in the loss of efficiency of the GEE estimation. In this study, we evaluated the efficiency of WGEE estimation for incomplete longitudinal data when the working correlation structure was misspecified. As a result, we found that the efficiency of the WGEE estimation was lower when an improper working correlation structure was selected, similar to the case of the GEE method. Furthermore, we modified the criterion proposed by Gosho et al. (2011) for selecting a working correlation structure, such that the GEE and WGEE methods can be applied to incomplete longitudinal data, and we investigated the performance of the modified criterion. The results revealed that when the modified criterion was adopted, the proportion that the true correlation structure was selected was likely higher than that in the case of adopting other competing approaches.
