Author Contributions

JML developed the cointegrating regression model and did all the calculations to fit the model and do the model validity and reliability tests. AD collected some of the data and performed the Monte Carlo simulations to estimate savings associated with the CTCP and the associated confidence intervals. SAG formulated the general question and the conceptual model. All three authors contributed to preparing the manuscript for submission.
