'Labor Economics' is George Borjas' (Harvard University) attempt at providing a textbook for undergraduate students on the subject of labor economics. The book's main objective is 'to survey the field of labor economics with an emphasis on 'both' theory and facts' since most labor economics textbooks allegedly overemphasize the development of economic modeling skills or the knowledge of a plethora of minute statistics relative to the economic theory of labor economics. My inability to judge this claim notwithstanding, Borjas certainly does a good job at introducing and explaining the many models featuring in modern labor economics. The exposition is supported by a vast amount of figures and tables, the average chapter displaying more than a dozen of graphs and figures, and a multitude of examples from all walks of economics.
Generally, a chapter begins with a short introduction to a set of stylized facts, the exposition of the economic theory developed to explain these facts and a detailed discussion of the empirical research linking the theory with the facts. Here, three comments are in order: First, Borjas is not shy of admitting the many issues where (labor) economics has not yet reached a consensus and question marks over the causes and effects of certain economic phenomena still loom large, which I strongly welcome. Second, Borjas often offers a - to the best of my knowledge - fair account of many economic policy issues in labor economics, though he is known as a rather conservative economist; nonetheless, it is not clear to what degree he engages with the criticism of his academic opponents, e.g. Borjas has precious little to say about David Carr's argument that immigration not only affects labor supply but also labor demand (U.S. immigrants buy their burgers in America, not in their countries of origin...). In the particular case of the U.S. minimum wage debate, he has not (yet) incorporated a flurry of recent research (e.g. Dube, Lester & Reich 2010, Allegretto, Dube & Reich 2011, Hirsch, Kaufman & Zelenska 2015, Sabia, Burkhauser & Hansen 2012), which have considerably moved the debate forward. I would like to extend this section of the review once I am able to compare his account with other textbooks' narratives of the disputed phenomena. Third, despite being labelled as international edition, the book is strongly centered on the United States, with most of the book's content focusing on the explanation of stylized facts concerning the U.S. economy, though this is to some extent due to the relative wealth of economic data and studies on the U.S. economy rather than the author's predilections (this is not to say that international comparisons are utterly absent, just that they take a third-row backseat relative to the U.S.). I hope to get my hands on a German textbook on labor economics by Wolfgang Franz soon, which ought to enable comparisons between both books and whether Borjas' focus on the U.S. can be seen as a drawback for its international edition.
The book consists of twelve chapters on (1) labor economics in general, (2) labor supply, (3) labor demand, (4) labor market equilibrium, (5) compensating wage differentials, (6) human capital, (7) the wage structure, (8) labor mobility, (9) labor market discrimination, (10) labor unions, (11) incentive pay, and (12) unemployment. Two important subfields of labor economics omitted by this selection are experimental and behavioral labor economics, though they sometimes implicitly surface in the narrative. The book also does not treat labor markets in developing countries separately, though one may question to what extent economics research based on industrialized countries' experiences generalizes at the global level.
The book ends with a mathematical appendix, an index and the absence of a bibliography. The absence of a bibliography impedes the book's use as a reference, which is not improved by the embarrassing quality of many citations (I found up to at least a dozen citation mistakes in a single chapter, something which should have been corrected a long time ago). The mathematical appendix is pretty standard and does not require any mathematical skills beyond advanced high school math. The index aggregates personal names and concepts.
In sum, I really liked this book: It wet my appetite for labor economics through its clear exposition and sophisticated balance between theory and facts. Absent the omission of certain (important) subjects and the bad quality of the citations the maximum rating would have been possible. I strongly recommend the book as a textbook for any undergraduate course in labor economics, though not as a reference.
