This book focuses on the modeling of the transitions in and out of unemployment, given the stochastic processes that break up jobs and lead to the formation of new jobs, and on the implications of this approach for macroeconomic equilibrium and for the efficiency of the labor market. --mitpress.mit.edu
You cannot rate this kind of book. It's a great resource for doing theoretical research in labor but it's not a light read and I would not recommend it for anyone who's not a PhD student or a researcher. However, if you are then this book is invaluable.
A side note: Obviously I have not read this from cover to cover but used it enough.
