Llewellyn Consulting provides a consistant, succinctly and tightly written research on a range of macroeconomic themes. They’ve just launched a new research series in response to the number of requests for periodic detailed analysis by theme. The series called ”Blue Book” will be on a specific theme that affects economies and markets; each will draw together everything important that they know and have written upon about the subject, generally over a run of years. Their first edition is on the interest rates theme where their essential argument is that the world will remain in an historically low interest rate configuration for the foreseeable future. Their reasoning is that world slow-growth environment seems likely to endure, while contributory factors include legacy effects from 2008 and broader structural considerations which are all explored here. It’s a excellent piece bring together a wide body of work, which is well worth exploring.
