The implications of this for, say, broadband Internet regulation have been discussed at length elsewhere, so I’ll leave it there. Sometimes business regulation improved social welfare, sometimes it didn’t, usually the key was exactly how the regulation was structured. Then a new generation of economists, with Tirole at the lead, showed that a rigorous, orthodox economic approach, if you threw in a little game theory and information asymmetry, actually delivered much more complicated results. The basic story is that early antitrust and regulatory ideas that didn’t have much basis in economic theory were brushed aside in the 1970s and 1980s by the University of Chicago-based “law and economics” movement, which basically taught that competition conquers all, even in pretty concentrated industries. In the “ Scientific Background” essay on Tirole’s work provided by the Nobel committee, the focus is on Tirole’s work on industry structure, which has had a big impact on antitrust and other regulation, especially in Europe. He then usually brings in the tools of game theory, in which his protagonists have to contend with other rational actors and the moves they might make. The models Tirole builds are mathematical in nature, and start with individuals or firms that are assumed to be rational creatures out to maximize their utility, their profits, or something else along those lines. Unlike Paul Krugman, another MIT PhD of Tirole’s generation with similar renown as a model builder who has gone on to a second career as a highly visible and controversial public intellectual, Tirole has mainly just kept on building those models - and at a seemingly youthful 61 will presumably just keep building them unless the prize curse gets to him. He is the eighth most-influential economist on the planet among his peers, according to the weighted RePEc citations ranking, and three of those above him on the list already have Nobels. In other words, Tirole does what modern academic economists do, only better than almost anyone else. “Obviously models have to simplify reality, but one of the real skills is essentially being able - it’s an art, not a science - to say, ‘What are the key levers here? What are the aspects that distill the situation down to its very essence?’” Here’s one key reason: “Jean has a bit of magical quality of being able to take very complex situations where there are a lot of different moving parts and a lot of institutional details and structuring the essence of it in a relatively simple model,” says Harvard Business School professor Josh Lerner, who has co-authored several recent papers with Tirole. So probably right now your head is spinning at the mere invocation of all these names and handbooks.Why did Jean Tirole win this year’s economics Nobel? You also probably saw the books written by various academics in the field of finance. You probably saw also the stock market analysts’ books – those written by the guys or girls who have been very successful as investor managers. This means that you saw the CFA (Chartered Financial Analyst) -endorsed books, such as the famous Investments by Bodie and Kane.
The theory of corporate finance tirole pdf professional#
If you are a seasoned professional working in corporate finance or as investment analyst, it is very probable that you've them all. It is used as a study text by many universities and it can be cited as a different approach on the already over-published field of the super-trooper and sophisticated corporate management of finances. I was a bit anxious, since this corporate study textbook (published summer 2009) has already become quite well known in the academic environment. It took me a while to get my fingers on this Princeton University Press book.
