Microeconomics : Optimization, Experiments, and Behavior

The most innovative feature of the book is its extensive coverage of recent research in behavioral and experimental economics. This research not only documents behavior inconsistent with some elements of traditional theory but also advances positive theories with superior predictive power. The research covered includes studies of loss aversion, reference-dependent preferences, the context and framing of choice, hyperbolic discounting and inconsistent intertemporal choice, predictable errors in updating probabilities, nonlinear weighting of probabilities, and prospect theory. The importance of this material was highlighted by the Swedish Academy of Sciences when it awarded the 2002 Prize in Economic Sciences to Daniel Kahneman (a psychologist who helped lay the foundations of behavioral economics) and Vernon Smith (an experimental economist). Although the topics are "advanced" in the sense that they are near the frontier of economic research and seldom-covered in textbooks, they are readily comprehended because they center on simple controlled experiments and relate to everyday concerns. Covering results from behavioral and experimental economics along with traditional microeconomic doctrine involves re-balancing three key components of economics: issues, theory, and data. Traditional introductions emphasize issues, sketch theory, and use data only to illustrate theory. More advanced texts traditionally focus on theory, relegating issues and data to asides. Any data in traditional texts are usually from observational (non-experimental) studies. The relationship between theory and observational data is likely to be ambiguous until probed by advanced econometric methods and may remain so even then. Recognizing that few students have the econometric skills needed for serious analysis of observational data, some authors focus their texts almost exclusively on theory and issues. Although widely used, such texts discomfort students and professors to whom data-free expositi
