PJM economics was founded in 2012 by Dr Paul Metcalfe to offer bespoke economic research and consultancy services to policy makers, regulators, and regulated businesses.

We are focused on the client’s need for robust evidence, communicated clearly and concisely. We understand that economics and econometrics can sometimes confuse rather than enlighten, and we make it our mission to prevent this from happening. The power of these tools can only be fully realised when accompanied by a clear and concise explanation of the methods, the assumptions on which they rely, and the way in which the results ought to be interpreted.
