Money Changes Everything

William N. Goetzmann. Princeton Press

My new book, Money Changes Everything, argues that the development of finance has made the growth of civilizations possible. Finance is a peculiar technology developed by humankind that allows us to move value forwards and backwards through time. This innovation has changed the very way we think about and plan for the future. Finance was present at key moments in history: driving the invention of writing in ancient Mesopotamia, spurring the classical civilazations of Greece and Rome to become great empires, determining the rise and fall of dynasties in imperial China, and underwriting the trade expeditions which led Europeans to the New World. This book traces the development of finance from its most ancient origins up through modern times and links it to the broader evolution of complex societies.

The The Great Mirror of Folly: Finance, Culture, and the Crash of 1720

William N. Goetzmann, Catherine Labio, K. Geert Rouwenhorst and Timothy Young (Editors), Robert Shiller (Foreword). Yale University Press, Yale Series in Economic and Financial History

My colleagues and I edited a volume about the first global financial crisis and the book that recorded it. The world's first global stock market bubble suddenly burst in 1720, destroying the dreams and fortunes of speculators in London, Paris, and Amsterdam virtually overnight. Their folly and misfortune inspired the publication of an extraordinary Dutch collection of satirical prints, plays, poetry, commentary, and financial prospectuses entitled, Het groote Tafereel de Dwaasheid (The Great Mirror of Folly), a unique and lavish record of the financial crisis and its cultural dimensions. The current book adopts the title. It is a book about the book, a wide-ranging interdisciplinary collaboration that uncovers the meaning and influence of the Tafereel and the profound, lasting, and multifaceted impact of the crash of 1720 on European cultures and financial markets.


The Equity Risk Premium: Essays and Explorations

Roger Ibbotson and I have  assembled our  separate  and co-authored  research papers related to the equity risk premium into a volume.  We have added additional new work and interpretive material. 


The Origins of Value: the Financial Innovations that Created Modern Capital Markets Geert Rouwenhorst and I have edited a volume of essays for the International Center for Finance published by Oxford University Press. It contains chapters by leading historians and economists on key innovations in finance from earliest times to the present. It is based on a series of conferences on financial history at the International Center for Finance at the Yale School of Management. It draws significantly from the new History of Finance Collection, a joint venture between the Yale Beinecke Library and the Yale School of Management's International Center for Finance. Find the book at Oxford University Press. Buy it on Amazon or Barnes and Noble. Hear the Marketplace Interview about The Origins of Value. Also, here are the reviews: The Times, Time Magazine, Financial Times, Barron's The Best Books of 2005 Frankfurter Allgemeine, The Times Higher Education Supplement, Financial Innovation

More Social Security, Not Less is a proposal to re-invent social security to meet the needs of all Americans. It argues for the transition of the U.S. Social Security Fund to a growth-oriented portfolio and offering additional annuities at a price that will support the basic social security contract. The 2005 working paper contains the basic proposition and is free to download here and here. The 2008 published version is also here.

The Dow Theory 

Stephen Brown, Alok Kumar and I have studied the performance of the Dow Theory over the period 1903 to the present. Using the editorials of William Peter Hamilton, we simulated the investment return achieved by someone who followed the theory. In addition, we used neural net methods to "extract" the theory from Hamilton's editorials, and test it out of sample. The working paper may be downloaded, and the published version appeared in the August, 1998 volume of the Journal of Finance. This site is a resource area for information about our analysis and the more recent Dow Theory performance.


Hedge Funds

Topics will include hedge fund compensation, performance evaluation, risk management, including operational risk, and the role of arbitrageurs in the capital market.

Finance in the Oxyrhnchus Papyri: An early bank check?

Document 2772 in The Oxyrhnchus Papyri volume XXXVI is entitled, Instructions to a Banker.

Translation: Julius Lepos to Archibius the banker greeting. Pay to my account with Harpochration the banker one thousand nine hundred and fifty three drachmas of silver. Total 1953 dr year 40 of Caesar, Pachon 3.
