A collection of articles on the topic of economic methodology. Economic methodology investigates the concepts, theories, and basic principles of reasoning which are part and parcel of the discipline of economics, or the philosophy of science as applied to economics. Use of the term 'economic methodology' is therefore not to be confused with 'method,' which includes as examination of data collection, sampling, and survey methods. The nine parts of this text include articles by prominent economists such as F. Machlup, R. Heilbroner, A. Coddington, L. Boland, H. Simon, and W. Leontief.
