This volume collects papers from Hugo Sonnenschein's students. It aims to demonstrate his tremendous impact as an advisor. The papers span decades and present some of the most important articles in microeconomic theory. Each paper is accompanied with a preface by the student providing background on the paper and indicating Hugo's influence on its genesis. The papers all lie in microeconomic theory, and moreover all make fundamental contributions to the foundations of the theory.

Strategy execution is one of the most important and exciting topics in management. Implementing strategy in today's complex organizations is an enormous challenge but one that all leaders must tackle. This lively book is an essential guide to strategy execution for practicing managers and those in advanced management education. It combines the rigour of advanced research with the accessibility of practical experience and application to lead readers through the subject.

Drawing together existing knowledge and reporting findings from his own research, Andrew MacLennan brings this often neglected topic sharply into focus. After introducing and defining strategy execution, the book presents a series of systematic frameworks to help managers and leaders:

• identify common strategy execution barriers and diagnose performance problems in particular situations
• translate conceptual strategies into concrete activities
• align emergent activities and projects with strategic objectives
• support critical activities by aligning organizational designs and systems

Strategy Execution is an insightful, engaging and practical book. The models are supplemented throughout with real world examples, summaries of key issues and signposts to further readings. It is a comprehensive, easy to use book offering students and practitioners a systematic approach to strategy implementation.

This book develops the central aspect of fixed point theory - the topological fixed point index - to maximal generality, emphasizing correspondences and other aspects of the theory that are of special interest to economics. Numerous topological consequences are presented, along with important implications for dynamical systems. The book assumes the reader has no mathematical knowledge beyond that which is familiar to all theoretical economists. In addition to making the material available to a broad audience, avoiding algebraic topology results in more geometric and intuitive proofs. Graduate students and researchers in economics, and related fields in mathematics and computer science, will benefit from this book, both as a useful reference and as a well-written rigorous exposition of foundational mathematics. Numerous problems sketch key results from a wide variety of topics in theoretical economics, making the book an outstanding text for advanced graduate courses in economics and related disciplines.
