"Pedersen's book can be recommended to a wide spectrum of readers interested in financial markets in general and hedge funds in particular."--Jacek Klich, Central Banking "Encyclopedic in its cataloguing of active management strategies and authoritative in its analysis of the practical issues of their implementation. Pedersen grounds his exposition in landmark scholarly articles and, where quantitative analysis is required to elucidate a concept, conveys his message without resorting to arcane mathematics."--Martin S. Fridson, Financial Analysts Journal "Despite the author's high level of understanding he manages to deliver a high quality but also easily understandable guide to the strategies."--Mats Larsson, Investing by the Books

It works beautifully."—Darrell Duffie, Stanford University"Efficiently Inefficient is a truly modern and masterful introduction to how finance will be studied and practiced in the twenty-first century."—Andrei Shleifer, Harvard University"How are markets efficient enough to stump most investors, yet inefficient enough to allow hedge fund managers to earn huge profits? Lasse Pedersen, who has contributed greatly to the 'new finance' of liquidity and financial frictions, answers this question with a tour-de-force combination of original research and provocative interviews with hedge fund managers."—Laurence B. Siegel, CFA Institute Research Foundation"Lasse Pedersen is a gifted financial market theorist who understands that theory is most satisfying when it is combined with a deep practical understanding of institutional detail and market frictions. This terrific book showcases his strengths in all of these dimensions."—Jeremy Stein, Harvard University"This accessible book explains hedge fund strategies and how to design, construct, evaluate, implement, and risk manage them. The section on securities lending and borrowing is interesting and novel, and Pedersen's discussion of macro and central bank strategies is one of the best I have seen in any book on hedge funds. His account of portfolio construction is superior."—Robert Kosowski, Imperial College Business School"Efficiently Inefficient bridges academic finance and the practice of finance.
