This study aims to analyze metaphors used in economic texts from the perspective of cognitive semantics, and the main focus is to investigate their underlying characteristics. Defining the analysis subject to include only economic texts broadcasted on radio in colloquial language, the study analyzes the characteristics by comparing the aspects of metaphors used in economic texts with others in different fields. First of all, it examines the similarities and differences between metaphoric aspects used in economic texts and those used in other texts of different areas, including science, athletics, and politics. As a result, metaphors used in colloquial economic texts show different metaphoric aspects, compared to those used in athletic and political texts. However, the analysis has also illustrated that, in terms of the expression and the purpose of use, there are a number of similarities between metaphoric characteristics used in economic texts and those used in scientific texts. Based on this finding, the study further analyzes metaphorical expressions used in colloquial economic texts by comparing them with those used in scientific texts in depth to see what metaphorical characteristics and effects they have when used in texts of these particular areas respectively. The result is the following: abstract concepts used by a particular profession and jargons were difficult for others to understand. However, as the difficult scientific and economic concepts are now frequently used by laypeople as well, it has recently become common to metaphorically describe them as more concrete and simpler concepts because people have already understood and acquired them. In light of this fact, it is easy to see that experimentalist theory conceived by G. Lakoff, which gave a rise to the field of cognitive semantics, has served the foundation of methods of metaphoric expressions described in scientific texts and economic texts. Scientific texts have made it possible to explain their complicated scientific concepts to the public by using metaphors since a long time ago. In fact, this same approach can be employed in (real-life) economics to explain specialized knowledge to readers(radio audience) as financial literacy has become common not only to experts, but also to the public. Furthermore, this method has been proven to be highly effective.
