‘Financial Economics in One Lesson’ is entirely researched and written by James Brierley. Overall, the book is suitable for a finance undergraduate or somebody new to finance who has some knowledge of economics or accounting. A person considering investing may take an interest, as well. In Part One, I describe internal and external finance. The latter consists of equity and debt – these form the basis of the whole book. The reader is introduced to equity analysis in Part Two, where we consider how we might identify good stocks, but we also ask whether we should even seek to. In Part Three, the economics and mathematics of bonds are presented and, from an investment strategy perspective, bonds are compared with stocks. Part Four discusses a financial derivative (options) and describes why they are useful and for whom they are risky. In Part Five, we give thought to numerical errors people often make – in finance, these have serious consequences, potentially – but we also look at basic econometrics. Parts Six and Seven see a discussion of today’s capital markets and economic conditions, including quantitative easing.
