Many researchers on metaphors in the field of economics have shown interest in the press coverage of economic events; some have included the discourse of textbooks, research articles or businesses in their investigations, and all have underlined frequent references to the economy as a machine or a human being. In this paper, I will endeavour to show how important it is to consider the recurring networks of organic or mechanistic metaphors in connection with theory-constitutive metaphors in economics. The diachronic perspective will show that metaphors can be seen as a reflection of the evolution of economic thinking over centuries, and can thus offer new insight into the field of economics. The heuristic function of metaphor will be discussed at different levelsthose of economic thinkers, ESP teachers and students. I will argue that, as far as terminology is concerned, many a metaphor that is considered as dead is actually just dormant and can be revived at any time to give birth to new metaphors branching out. Metaphors that seem to lose ground, disappear or re-surface, are worth paying attention to as they may reflect a turning point in theory, and spur new approaches to economic problems. In this respect, I will venture to plead for an observatory of metaphors, modelled on neology observatories, with a view to monitoring the emergence of new metaphors. Metaphor could then either be considered as a motor or a barometer of scientific progress and social evolution as well.
This article aims to study some of the features that characterize Federal Reserve Board Chairman Alan Greenspan’s language. After a brief assessment of the readability of the texts of his public speeches and reports, an analysis of specific linguistic elements that contribute to the complexity of his discourse is given. Hedging devices and their blurring effect are reviewed, and, beyond them, specific lexical, syntactic and discursive choices are investigated, which help Mr Greenspan to preserve a dose of ‘fuzzy transparency’ in his pronouncements. It seems that it is precisely this varied mix that makes his discourse so peculiar and puzzling for the reader.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
