A collection of papers dicussing unknowledge and choice in economics. The topics focus especially on G.L.S.Shackle's theories and his place in subjectivist thought but also include time, choice and dynamics in economics and interest rates and investment decisions.

This volume unites scholars from all over the world, and with very different theoretical perspectives. Their chapters probe into typical Shacklean themes of time and money, uncertainty and expectation, and into the roots of G.L.S. Shackle's philosophical and methodological stance.

This volume contains the correspondence between G.L.S. Shackle and S.F. Frowen from the time Shackle took up his first post-war academic appointment until his death in 1992. The correspondence, partly personal and partly professional, reveals a vital insight into Shackle both as a man and as an outstanding economist. His letters illuminate his thoughts on issues occupying his mind but also show the warmth and tremendous generosity he felt towards his friends. The centenary of Shackle's birth in 2003 seems an appropriate time for the publication of his letters.

This Festschrift was "presented" in electronic form to Buchanan on the occasion of his eightieth birthday on October 3, 1999, after dinner in Fairfax, Virginia. As one might have expected, the response to our call for papers was vo luminous. In looking over the many contributions, we felt that a "published" Festschrift was also possible and fitting for the eightieth birthday of so prodi gious and influential a scholar as Professor Buchanan. To that end we have assembled the following volume. In selecting the papers to be included here we have basically tried to choose those papers which in some way bear on Buchanan's contributions. Perfectly good papers about issues not related to Buchanan's research agenda or not referring directly to Buchanan's work were not included. Space constraints did not allow universal coverage, so choices had to be made. It should be stated clearly that these were our choices based on the criterion that the contribution be relevant to Buchanan's work. Buchanan had nothing whatsoever to do with the selection of papers for this volume. Once choices had been made, we arranged the papers by subject matter ranging from various aspects of Buchanan's work in economics, political science, philosophy, and related areas, to some more personal recollections of Jim as a professor, friend, and colleague. Including the latter material was also our decision, and this probably represents a choice with which Jim would not have agreed. We think, however, that the reader will find these pieces interesting and informative.

This book presents essays by an outstanding team of international specialists and covers a wide range of topics, including (inter alia) the relationships between the Austrian and Swedish theories of the business cycle, the on-going debates between Austrians and (Post) Keynesians, Schumpeter's 'Walrasian' stand in the socialist calculation debate, and the Austrian roots of Neo-Institutional economics. The studies stress the unique Austrian contributions to economic methodology and to the theory of entrepreneurship, while revealing unexpected methodological and philosophical similarities between, among others, Hayek and Marx.

Throughout the history of economic ideas, it has often been asserted that experimentation is impossible, yet, in fact, history shows that the idea of ‘experimentation’ has always been important, and as such has been interpreted and put to use in many ways. Rich in historical detail, the essays in this topical volume deal with such issues as laboratory experimentation, the observed transition from a post-war economics to a contemporary discipline, the contrasting positions of Friedrich Hayek and Oskar Morgenstern, the socio-economic experiments proposed by Ernest Solvay and Knut Wicksell, and a rigorous examination of the way in which economic models can or cannot be construed as valid experiments producing useful knowledge. A testament to the variety of ways in which experimentation has been of importance in the creation of economic knowledge, these wide-ranging essays will interest those seeking to expand their historical understanding of the discipline, be they theorists, historians, philosophers, advanced students or researchers.

Notions of probability and uncertainty have been increasingly prominant in modern economics. This book considers the philosophical and practical difficulties inherent in integrating these concepts into realistic economic situations. It outlines and evaluates the major developments, indicating where further work is needed. This book addresses: * probability, utility and rationality within current economic thought and practice * concepts of ignorance and indeterminancy * experimental economics * econometrics, with particular reference inference and estimation.
