RebelText: Essentials of Development Economics, by Ed Tylor with Travis Lybbert, is an alternative to traditional development economics textbooks. It was written as a compact book for an upper-division undergraduate development economics class, and it comes with its own "living" website. This book is unique in making cutting-edge development economics research from journal articles and other sources accessible to undergraduates. QR codes bring the internet into the textbook. You can also use the book and website as part of a self-paced, independent-study course or as a companion for graduate-level texts. We strive to present best practices and state-of-the-art methods for doing intermediate development economic work. The knowledge in these pages should poise anyone for further study or to venture out into the real world with essential development economic concepts and tools, along with a feel for the subject that is not found in other undergraduate texts. "Taylor and Lybberts exciting and relevant new development economics RebelText offers a creative and flexible alternative to traditional textbooks. "RebelText: Essentials of Development Economics" gives students a manageable set of textbook essentials and a dynamic website with current resources around which instructors can build unique course content. Students will love the price tag, and innovative instructors will like the flexibility it provides them to help students explore the latest research and understand what development economists really do. I plan to use this book in my own course." -Edward Miguel, Professor of Economics, University of California, Berkeley
