This book provides a unique bridge between theoretical foundations and practical implementation of environmental economics modeling. Through a progressive approach, it guides readers from basic analytical frameworks to advanced computational techniques for analyzing climate change policies. Starting with intuitive partial equilibrium models, the book systematically builds understanding of three major modeling frameworks: Environmental Dynamic Stochastic General Equilibrium (E-DSGE), Dynamic Integrated Climate-Economy (DICE), and Computable General Equilibrium (CGE) models. Each framework is thoroughly explained with detailed MATLAB implementations, making complex concepts accessible and practical. The books distinctive two-part structure serves multiple audiences: Part I develops fundamental concepts through analytically solvable models ideal for advanced undergraduates, while Part II explores sophisticated modeling approaches suitable for graduate students and researchers. Throughout, readers benefit from: Comprehensive coverage of carbon taxation, cap-and-trade systems, and other environmental policy instruments Detailed MATLAB code for implementing theoretical concepts Clear connections between different modeling approaches for policy analysis Whether youre an economics student learning environmental modeling, a policy analyst working on climate regulations, or a researcher comparing modeling frameworks, this book provides the tools to engage with modern environmental economic analysis.
