Richard Werner is a bit nutty but his work does have value. He takes a heavily heterodox position on interest rates, some of this is him being misleading in order to be controversial. But his points about the impact of interest rates on bank profits are very trenchant (and btw, the reason why he is a bit nutty is because his professional experience was Japan in the late 80s/90s, that scenario tested all the assumptions about macro and found a lot of them were false, his book Princes of the Yen is good...although, again, very heterodox).
