This new intermediate microeconomics text blends conventional topic coverage, recent developments in microeconomic theory and material that explores a broader conception of rational economic decision-making behaviour. The book covers all the analytical tools students should learn, while developing their economic intuition; at the same time the book presents core microeconomic theory in a careful and patient manner using simple examples. It is equally suitable for undergraduate microeconomic theory courses at the intermediate level, or MBA course in microeconomics. Special features of the text include applications and examples; coverage of elasticity and its applications to demand theory, as well as the average-marginal distinction in production theory; new topics, such as the economics of price discrimination, a spatial model of monopolistic competition, a careful introduction to game theory and strategic behaviour, and the policy implications of the modern theory of monopoly; and a chapter, "Beyond Self-Interest?", that relates ethics and economics.
