More than two hundred and fifty years after pure economics' birth, errors related to the value of money concept have not been satisfactorily addressed in the literature. Pure Economics is an in-depth and authoritative exploration of those and other fundamental errors, including in Decision and Game Theory. Drawing light to the often-contradictory work of microeconomic theorists, the author shows the math behind flawed equations and offers correctives. This isn't simply a calling out of erroneous work-rather, Professor Barzilai provides proof and solutions.
