In presenting the first detailed account in English (and Spanish) of the Spanish economic thought from the Medieval age to the twentieth century, this book provides a balanced combination of information and interpretation. Paying particular attention to the main transformations between 1550 and 2000, this important work gives an interpretation based on current historical criteria (such as the complementary use of focuses from the history of economic analysis, the history of economic ideas and the history of economic doctrines). Closing with a discussion on the progress of the different forms of economic knowledge, this book will be a valuable resource for postgraduate students of the history of economic thought.
