Parthenia Research is backed by several senior property figures as well as investors from outside of the industry. These investors believe the only way to determine relativity (the relative value of a lease without rights to the freehold) is through using pre 1993 Act market evidence, as this avoids the impact of the legislation and more importantly the influence of the erroneous graphs (often sponsored by freeholders).

The academic research was undertaken by Philippe Bracke (PhD London School of Economics), Edward Pinchbeck (PhD London School of Economics) with James Wyatt F.R.I.C.S. (MPhil University of Cambridge) and the underlying paper has been published by the Bank of England, London School of Economics, Royal Economic Society and by the top ranked peer reviewed Economic Journal. The work has been extensively tested and reviewed by the leading economists including Professors Cheshire and Gibbons (LSE), Professor Muellbauer (Nuffield College, Oxford), Professor Holly (Fitzwilliam College, Cambridge) and Professor Meen (University of Reading).
