Chapter I begins by describing the salient parts of a formal science of economics that the author has put together in this book and in earlier works (B.P. Stigum 1990 and 2003). The parts comprise a unitary methodological basis for a science, an explication of the meaning of facts and fiction in econometrics, and a confrontation of the methods of present-day applied econometrics with the methods that a formal science advocates. Next the chapter discusses interesting ways in which the axiomatic method and the model-theoretic method of developing theories are used in mathematical economics and statistics, and describes the underlying ideas of a formal theory-data confrontation. Thereafter follows a discussion of three controversial aspects of formal econometrics: (1) the essence of an economic theory; (2) the double role of theory in applied econometrics and the need for bridge principles; and (3) why theory is required both for the design of an empirical analysis and for the interpretation of its results. The chapter ends with a brief description of the contents of the remaining nine chapters.Less

Econometrics is a study of good and bad ways to measure economic relations. This book discusses the role economic theory ought to play in such measurements. The role theory should play, depends on the researcher’s ideas about the essence of an economic theory. A researcher who believes that his theory is about the actual workings of an economy, can identify his theory’s variables with objects in social reality and solve his measurement problems with the means that present-day econometrics provides. A researcher who believes that his theory is about imaginary matters that have uncertain relations to objects in social reality, faces measurement problems that he can solve with the means that formal econometrics provides. The book presents case studies thatcontrast the empirical analysis of present-day applied econometrics in the tradition of Trygve Haavelmo with the empirical analysis of formal econometrics in the tradition of Ragnar Frisch. The case studies are a varied lot in which the theory is static or dynamic and faces cross-section data or time-series data. In focus are the behaviour of data variables and the inferences about social reality which the empirical analyses yield. The case studies demonstrate that both the statistical analyses and the inferences of present-day and formal econometrics differ in striking ways. In doing that they provide a good basis for discussing the use of theory in measuring economic relations. The book is the last of three books in which the author develops and demonstrates the usefulness of a formal science of economics.Less
