For those that are interested in understanding banking and finance in general and investment banking and volatile and risky financial markets in particular, I have just published a relevant article in Journal of Cultural Economy. It is based on my studies of equity analysts and risk control management in banks. It shows how equity analysts produce dissensus regarding the value of equity and thus influence investors to trade more and in a speculative ways than if the analysts did not do what they do. It is quite technical and if your not into current micro-sociological theory or organizational analysis it might be a little bit hard to read – but give it a try!
