As economic planners sought to rebuild Europe in the unstable postwar period, economic expertise was called upon to help in the drawing of national budgets and to inform economic and planning policies. A tool that circulated from academia to economic administrations was the input-output...

This paper documents an early fork in the development of macroeconomics, by examining a debate between the Dutch economists Jan Tinbergen and Johan Koopmans. In a 1932 paper, Tinbergen argued that two firms could be stuck in a 'bad' equilibrium in the absence of a coordinated action to increase...

Little is known about the relationship between Carl Menger, founder of the Austrian School of Economics and one of the three fathers of marginal utility theory, and Karl Menger, whose Vienna Mathematical Colloquium was crucial to the development of mathematical economics. The present paper...

A popular view of models among economists and philosophers alike is that all models are false, but some are useful. Models are frequently treated as convenient fictions, idealizations, stories about credible worlds, or "near enough" to the truth. But such a understandings pose serious questions,...

In the paper, Edwin B. Wilson's influence on the rise of mathematical economics in America between the 1920s and 1940s is explored. The focus is laid on showing how on the grounds of his foundational ideas about science Wilson worked at the organizational and educational fronts to modernize...

This paper is an exploration of the genesis of Paul Samuelson's Foundations of Economic Analysis (1947) from the perspective of his commitment to Edwin B. Wilson's mathematics. The paper sheds new lights on Samuelson's Foundations at two levels. First, Wilson's foundational ideas, embodied in...

The concept of 'the core' originates in cooperative game theory and its introduction to economics in the 1960s as a basis for proofs of existence of general equilibrium is one of the earliest attempts to use game theory to address big questions in economics. Discovery of the core was met with...

In recent academic and to some extent public debates, mainstream economics has been accused of excessive mathematization. The rejection of mathematical and other formal methods is often cited as a crucial trait of Austrian economics. Based on a systematic discussion of potential benefits and...

Trygve Haavelmo's The Probability Approach in Econometrics (1944) has been widely regarded as the foundation document of modern econometrics. Nevertheless, its significance has been interpreted in widely different ways. Some modern economists regard it as a blueprint for a provocative, but...

The potted histories of macroeconomics textbooks are typically Keynes-centric. Keynes is credited with founding macroeconomics, and the central developments in the field through the early 1970s, including large-scale macroeconometric models are usually termed "Keynesian." The story of...
