Modeling Monetary Economies

Thoroughly updated and expanded with a new chapter on blockchain and increased coverage of cryptocurrency, as well as new data, this established advanced undergraduate textbook approaches the subject via first principles. It builds on a simple, clear monetary model and applies this framework consistently to a variety of monetary questions. Starting with trade being mutually beneficial, the authors demonstrate that money makes people better off, and that government money competes against other means of payments, including other types of government payments. After developing each of these topics, the book tackles the issue of money competing against other stores of value, examining issues associated with trade, finance, and modern banking. From simple economies to modern economies, the authors address the role banks play in making more trade possible, concluding with the information problems plaguing modern banking.
