1.0 out of 5 stars
Overly and unnecessarily complicated,
By Mychailo Maynard (Vancouver) - See all my reviews
This review is from: Choices: An Introduction to Decision Theory (Paperback)
I am actually floored by the previous review. I can't imagine anyone liking this book. The author overcomplicates everything and does all his math within his writing. Many steps are skipped and it's left up to the reader to fill in the blanks. Why he couldn't write the problems out I don't understand. Perhaps he was trying to save paper.

This review is from: Choices: An Introduction to Decision Theory (Paperback)
I have to admit, this wasn't a book I thought I'd read, but I came across it in a college library, glanced through it and ultimately later decided to buy and read it. I was surprised at the odd ways that decisions are made by everyday people, and the misconceptions upon which those decisions are made. Once explained, the reality of some premises was quite clear, and I could even see where I myself had been led astray in my own decision making on more than one occasion. This is a clearly written work that even the average reader will understand and appreciate.

Good course-accompanying textbook,
By komkon2 - Published on Amazon.com
This review is from: Choices: An Introduction to Decision Theory (Paperback)
On its 216 or so pages, Resnik's book covers most themes of modern decision theory: decisions under uncertainty, under risk (with separate chapters on probability theory and the concepts of utility), game theory, and social choice theory. The book is clearly written and manages a good balance between the formal (probability calculus, techniques, proofs of major theorems) and the more philosophical discussions of underlying concepts and well-known paradoxes. Each of the six, 20-40 pages long chapters is divided into sections no longer than 3,4 pages, and each section closes with exercises (solutions not provided). Given about two sessions per chapter, the book is well suited as course material for undergraduate courses in philosophy, economics or statistics. This is also how I learned to know it.Returning to the book in preparation for an exam, I could not help to notice a few flaws. First, the book is now quite old (1987). It lacks a detailed discussion of preference relations and choice functions (e.g. Sen's conditions alpha, beta, gamma, the limit assumption), and there is also no part on backward induction in games that has become so fashionable. There are some excentricities, like that the "battle of the sexes" problem is rephrased in more "appropriate" terms, and it would be nice to have more historical background for the paradoxes (but you can easily look those up with a search engine). In the later chapters, specially the final one on social choice, the author goes through heaps of heavily formal constructions, and while earlier such constructions were carefully explained using graphics and everyday life examples, the reader is now asked in the exercises to invent his own graphs, prove important theorems etc. Condorcet's paradox on majority decisions could have used a more thorough discussion, both philosophically and theoretically (failure of transitivity, failure of Sen's condition beta). This does not make it less useful as a textbook, it only means that some chapters require more extra preparation and explanation on the part of the teacher than others. All in all, this is a readable, reliable and concise textbook. It is written well enough that students might actually read parts of it. However, after 20 years it would be nice to have a revised, more up-to-date version. 9 of 12 people found the following review helpful

An easy way for the game theory,

This review is from: Choices: An Introduction to Decision Theory (Paperback)
The author talks longer about the decision theory, particullary in two different context, related to the utility and the probability.The formalism is no hard, also we have an approach which considers the traditional questions, therefore he uses the axioms for a theory more apted to the applications. A particular attention must be related to the Arrow theorem, what is descript with many details for the proof,connecting that with the Harsanyi position. |
