He was awarded the Alfred Nobel Memorial Prize in Economics for this and other contributions to applied econometrics.The 20th century witnessed a great expansion of economics as a scholarly discipline. The editor has chosen a selection of papers which sparked his interest as a student, a teacher and a researcher. This key volume includes both classic articles as well as lesser known papers which Professor Klein judges will stand the test of time.

Robert Solow has made a seminal contribution in the field of aggregative economics. This authoritative volume will be an important starting point for any researcher or professional economist seeking to understand how this branch of economics advanced in the twentieth century.

James Buchanan has been a key figure in the integration of the analysis of political decision-making into the corpus of economic theory, the source for what is now called 'public choice economics'. This notable volume seeks to identify for future generations the landmark contributions to this area made in the twentieth century.

Kenneth Arrow and Gerard Debreu have throughout their careers continuously produced ideas at the very frontier of economics. Together, they have made unparalleled contributions on the properties of general equilibrium systems in economics, the study of collective choice and welfare economics. The editors have shown their usual rigor in selecting those papers which, in their view, have made the most important contributions in their particular areas of expertise. This volume will be an essential source of reference for students, researchers and practitioners alike.
