In regulated price controls, a key input is the determined cost of capital. This has often been a subject of appeals against regulatory judgements. Cost of capital analysis also feeds into assessments of profitability in assessing whether firms have been charging prices above the competitive level, and into the valuation of research pipelines in mergers.

It uses observational study data of the same units across time and requires that the units (firms, individuals or countries) are divided into treatment and control groups. Difference-in-difference estimates the effect of an intervention by comparing the average change in the outcome variable experienced by the treated group over time to the average change in the outcome variable experienced by the control group.
