Intermediate Microeconomics: A Tool-Building Approach is a clear and concise calculus-based exposition of current microeconomic theory that is essential for students pursuing degrees in economics or business. The second edition explicitly incorporates constrained optimization techniques. This beautifully presented and accessible text covers all the essential topics typically required at the intermediate level, from consumer and producer theory to the market structures of perfect competition, monopoly, duopoly, and oligopoly. Other topics include general equilibrium, risk, and game theory, as well as chapters on externalities, asymmetric information, and public goods. Through numerical examples as well as exercises, the book aims to teach microeconomic theory via a process of learning-by-doing. When there is a skill to be acquired, a list of steps outlining the procedure is provided, followed by an example to illustrate how this procedure is carried out. Once learned, students will be able to solve similar problems and be well on their way to mastering the skills needed for future study. Intermediate Microeconomics presents a large amount of material in a concise way, without sacrificing rigor or clarity of exposition. Through use of this text, students will acquire both the analytical toolkit and theoretical foundation necessary in order to take upper-level field courses in economics, such as industrial organization, international trade, and public finance.

Leonid Hurwicz (1917-2008) was a major figure in modern theoretical economics whose contributions over sixty-five years spanned at least five areas: econometrics, nonlinear programming, decision theory, microeconomic theory, and mechanism design. In 2007, at age ninety, he received the Nobel Memorial Prize in Economics (shared with Eric Maskin and Roger Myerson) for pioneering the field of mechanism design and incentive compatibility. Hurwicz made seminal contributions in the other areas as well. In non-linear programming, he contributed to the understanding of Lagrange-Kuhn-Tucker problems (along with co-authors Kenneth Arrowand Hirofumi Uzawa). In econometrics, the Hurwicz bias in the least-squares analysis of time series is a fundamental and commonly cited benchmark. In decision theory, the Hurwicz criterion for decision-making under ambiguity is routinely invoked, sometimes without a citation since his original paper was never published. In microeconomic theory, Hurwicz (along with Arrow and H.D. Block) initiated the study of stability of the market mechanism, and (with Uzawa) solved the classic integrability of demand problem, a core result in neoclassical consumer theory. While some of Hurwicz's work were published in journals, many remain scattered as chapters in books which are difficult to access; yet others were never published at all. The Collected Papers of Leonid Hurwicz is the first volume in a series of four that will bring his oeuvre in one place, to bring to light the totality of his intellectual output, to document his contribution to economics and the extent of his legacy, with the express purpose to make it easily available for future generations of researchers to build upon.
