Economics is an essential discipline that shapes our understanding of how individuals, businesses, and governments make decisions in the face of scarcity. Among its two primary branches, microeconomics focuses on the behaviour of individual economic agent’s consumers, firms, and markets providing fundamental insights into price determination, market structures, consumer choices, and resource allocation. Principles of Microeconomics: A Comprehensive Guide for Bachelor of Arts Students is designed to serve as a foundational text for undergraduate students, particularly those pursuing a Bachelor of Arts degree in Economics. The book is divided into several well- organized chapters covering essential topics such as demand and supply, elasticity, consumer behaviour, production and cost theories, market structures, and the role of government in economic regulation. Special attention is given to real-world applications, case studies, and contemporary economic issues to help students bridge theoretical concepts with practical understanding. A key feature of this book is its emphasis on critical thinking and analytical skills. Each chapter includes thought-provoking exercises, review questions, and problem-solving scenarios that encourage students to apply economic principles to everyday situations. Additionally, graphical illustrations and mathematical models are used where necessary to enhance comprehension. This book is intended for students new to microeconomics as well as those looking for a structured review of fundamental concepts. Whether used as a primary textbook or a supplementary resource, Principles of Microeconomics aims to make economic learning engaging, relevant, and intellectually stimulating.
