Puzzles and Paradoxes in Economics

Book excerpt: Economics is full of puzzles and paradoxes that often frustrate and challenge everyone, including economists. This engaging book includes fifty puzzles and focuses on three types of paradox. First, everyday observations that appear to belie common sense (such as why some supermarket items sell for more per ounce in larger sizes). Secondly, those paradoxes which have perplexed economists in the past but have since been fairly resolved (such as the diamond–water paradox). Finally, empirical or conceptual anomalies that remain unresolved and present a challenge to today’s economists (such as the voting paradox).
