Review title: the best book I have ever read Product review: I am a biochemistry student in mainland China. I have long wanted to have this book, but unfortunately the book is not available in China. Last month, my friend who is a Canadian citizen bought this book in North America and gave it to me as a present. I was greatly delighted. This is the best molecular and cell biology textbook I have ever read. And I have spent many pleasurable hours reading this wonderful book.

Review title: Disappointment Product review: Sharing the sentiments of the two previous posters, I think this book is a disappointment. For example, the second macro model presented by Romer -- the Ramsey-Cass-Koopman model -- is absent of optimal control theory. Setting up the Hamiltonian and showing how to dervive the Euler's equation of the optimal consumption path of the representative consumer would be a better treatment of the topics. This book, I think, lacks basic techincal tools essential for econ Ph.D. students. I am a microeconomist-wanna-be, this book makes me wonder what on earth is macroeconomics -- something very mysterious to me. Who are going to write a better text for graduate-level macro for non-macroeconomists???

Review title: I hope I can save you Product review: There is a bit to be encouraged about after reading this book. This book demonstrates that you need absolutely no talent, abilities, or any skill what-so-ever in wrting to become a published author. It appears Bantam Spectra will publish any piece of trash you send them. Be warned, delete your browse history, turn off your computer, take a cold shower, go for a long walk, just do not read this book. I just hope I can prevent someone else from suffering the same fate that I did. You have been warned.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
