This is the second edition of my lecture notes for the first quarter of a microeconomics course for PhD (or MA) economics students. The lecture notes were developed over a period of 20 years during which I taught the course at Tel Aviv, Princeton, and New York universities.
I published this book for the first time in 2007 and have revised it annually since then. I did so with some hesitation since several superb books were already on the shelves. Foremost among them are those of David Kreps. Kreps (1990) pioneered the shift of the game theoretic revolution from research papers into textbooks. His book covers the material in depth and includes many ideas for future research. His recent book, Kreps (2013), is even better and is now my clear favorite for graduate microeconomics courses.
There are four other books on my shortlist: Mas-Colell, Whinston and Green (1995) is a very comprehensive and detailed textbook; Bowles (2003) brings economics back to its authentic political economics roots; Jehle and Reny (1997) has a very precise style; and finally the classic Varian (1984). They constitute an impressive collection of textbooks for an advanced microeconomics course. My book covers only the first quarter of the standard course. It does not aim to compete with these other books, but rather to supplement them. I published it only because I think that some of the didactic ideas presented might be beneficial to both students and teachers and it is to this end that I insisted on retaining its lecture notes style.
