The current paper analyzes the effects macroeconomic variables on inflation in of Sudan. The selected data set was from 1990-2008. During that time there were significant changes in macroeconomic policies that had strong impacts on the performance of the Sudanese economy. A strong wave of...

Milton Friedman is usually regarded as an instrumentalist on the basis of his infamous claim that economic theories are to be judged by their predictions and not by the realism of their assumptions. This interpretation sits oddly with Friedman's empirical work - e.g., Friedman and Schwartz''s...

In a 1957 paper, Robert Solow exploited the mathematical properties of the aggregate production function to isolate the role of disembodied “technical change” in economic growth. Solow's method allowed to disentangle the role of technical change from that of production factors, with the...

In this paper, we use archival sources, interviews, bibliometrics, text-mining and correspondance analysis to trace the development of a loose community of economists interested in indeterminacy and sunspots. We propose several explanations for the rise, marginalization and eventual...

This paper extends various arguments in the recent historical literature on Soviet mathematical economics during the Cold War. It will examine some of the tensions associated with the attempt to blend Walrasian economics and Soviet planning. The main argument is that the two literatures crossed...

Economics today is a model building and testing science. But scientific economics was not always understood in terms of models. Economics first emerged as a separate field of scientific study in post-bellum America. The laissez-faire orientation of early American moral philosophy gave way to...

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...

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 article takes a fresh look at reswitching. When two production techniques are compared, reswitching occurs when one technique is more viable than the other at a high interest rate, switches to being less viable at a lower rate, and reswitches to being more viable again at even lower rates....
