5.0 out of 5 stars
The modern approach to econometrics, January 28, 2001
By A Customer
This review is from: Econometrics (Hardcover)
The title is accurate. This is 'Econometrics' done properly.
Unlike the vast majority of econometrics texts, this book combines solid economic theory with a thorough grounding in basic mathematical statistics. The worked practical examples introduce some classic empirical papers and provide an excellent motivation to study the theory. The little bit of effort required to put on the GMM-tinged glasses makes everything look so much clearer.
The incidental treatment of linear algebra is better than that of any 'Math. for Economists' book I have ever come across.
Anyone at the graduate level of study should own this book. It would also be of value to advanced undergraduates, and out-of-touch academics.
It should be noted that an important aspect of statistical analysis is the treatment of 'outliers', such as the 'review' presented by Mr. Brian J. Phillips.

Solid basis for econometric analysis, April 2, 2006
This review is from: Econometrics (Hardcover)
I have a love/hate relationship with this book. Perhaps I should state as a precursor that I was never formally trained in economics before learning econometrics. And, that the last time I'd done matrix algebra or calculus was some 15 years prior.
We used this book as part of a taught graduate course. It took half a semester to go through the first two chapters - an investment of time that proved well worth it for the rest of the topics which were covered in the remainder of the semester.
Basically, if you can understand the first two chapters on ordinary least square regression for finite and large samples, the required assumptions and properties, then the rest of the chapters are a piece of cake:
- generalized method of moments for single and multiple equations
- panel data
- time series analysis (including unit root analysis)
- extremum estimators
- maximum likelihood
- cointegration.
In short, the book covers all major econometrics topics and does so in a succinct, clear manner. The way in which Hayashi builds on each topic, showing that all models are basically different versions of the same method, with slightly different assumptions is just brilliant. It put statistics in a different light for me, and gave me a much deeper, intuitive understanding of it than any other book or class had done before.
There is a caveat however. This book assumes that you have substantial mathematical grounding. In particular, I found the succinct use of notation, without any verbal explanation, irritating at first. I invested quite some time in a mathematical economics book reminding myself what sets were, rules of matrices, calculus functions, expectations and probability.
Without the support and input of our brilliant teacher who (very patiently) took us through the end of chapter exercises step-by-step, I would never have managed to successfully read this book on my own! While those exercises honed my skills and deepened my understanding, I relied heavily on Hayashi's home page notes and hints to complete them.
For those of you that have strong mathematical skills and an economic background, this book is probably one of the best introductions to econometrics. For those of you who do not, it will prove to be a difficult read at best.
What's certain is that after succesfully completing it, your econometrics and statistical skills will provide a solid enough basis for any graduate program.

The Most Readable Econometrics Text There Is. Period, October 17, 2004
This review is from: Econometrics (Hardcover)
I think Hayashi is the best econometrics textbook to come along in a long time. The treatment has that rare quality of being simultaneously sophisticated yet very easy to follow. In that sense, this book is much different than Greene - whereas Greene is (I think) much more of a reference, you can actually sit down and learn a lot of econometrics with this book. Hayashi not only takes the time to explain key concepts in good prose, but in some cases even writes down step-by-step instructions. All this while not compromising the material.
The treatment is also slightly different in that GMM is a central theme instead of something off to the side, which is very nice. There are plenty of empirical examples - these are somewhat helpful, and the exercises are fairly easy but still illustrative.
Two downsides - it would have been nice to see some treatment of Bayesian econometrics, since this appears to be used much more widely (Lancaster is a good supplement). Second, either I got a faulty book, or there are no tables of critical values. This is ultimately a minor gripe since just about every other book has tables (and you really don't even need them these days with packages and such), but it can be annoying.
Ultimately, the combination of sophistication and readability of this book is what sets it apart from all others. If you're looking to learn econometrics, buy this book.
