An academic economist constructs a mathematical model predicting that carbon taxes will reduce industrial emissions. To evaluate this model, they collect quarterly emission data from countries that implemented a carbon tax and compare it to a control group, subsequently adjusting the model's parameters based on the observed differences.
This research process is best described as

formulating normative statements to dictate environmental policy.
applying scientific methodology to construct and refine positive economic theory.
employing the ceteris paribus assumption to isolate the effects of the tax.
