This book consists of a number of case studies with a financial market theme. The chapters are not ethnographies, because they are just the backdrop for the author's theoretical descriptions. Very little data are actually presented about the cases; barely enough for the author to make his points.
The author uses very unclear terminology. Two examples: (1) "Actors are agencements". The latter term is not really defined; unless you consider "Agencements denote socio-technical arrangements..." a proper definition. Personally, I want to have new terms defined clearly. I don't want to read that for epistemological reasons it is not possible to provide clear definitions. (2) "Innovation isn't linear". An example of this is when there are incremental innovations later in time after a major innovation. The additional innovations somehow destroys the linearity. When I read "isn't linear", I think "circular" or maybe "non-linear" (ie exponential). Again the author makes no attempt to make things really clear. (If it were not such a waste of time I would like to do a Derridaean deconstruction of the text to understand the underlying assumptions of its author.)
The author has ten precepts (two mentioned above), which are selectively applied to the case studies. Ideally all ten precepts should be applied to case studies, according to the author. (We can see his PhD students making a check list already!) The sparsity of factual information about the cases and the unclear precepts, makes it impossible to come up with any alternative understanding. You just have to take what the author says at face value.
Who will take what the author says at face value? This is a question worth thinking about. People that like to listen to authority? People that think they are smart and will understand what the author is saying if they just study a bit more? People that are ideologically certain about epistemology and find the author's epistemology appealing? People that are dependent on the author (PdD students, colleagues)? People that are stupid?
Finally, if you have a practical bent and want to understand the real world (and maybe even make it better), you should understand that the author does not seem to have any such inclination. He seems happy to just apply his precepts to a case study, and then move on to the next case study, and then the next.
One generation of academics applied Marxism to understand social science. Now they have fortunately moved to the retirement home. A new generation of academics apply Post-modernism to understand social science. We have to wait another 20 years for them to go to the retirement home. Both the "isms" had valid new ideas, but when the herd followers consider them ideological lenses to explain the world something unforgivable has occurred.
I will still continue to read the Clarendon Lectures in Management book series, but I will be more discerning in the future.
