Exploring the Macrostructure of Research Articles in Economics

Background: The cognitive load involved in research article (RA) reading can be overwhelming for L2 novice readers. RA section headings can be used as signals to help novices focus on essential information related to their learning goals to reduce extraneous cognitive processing. There is a need to examine RA macrostructures to inform RA reading instruction. Literature review: RAs do not always follow the Introduction-Methods-Results-Discussion (IMRD) model. Previous research has examined the macrostructure of articles in disciplines such as computer science, applied linguistics, and pure mathematics, but few have investigated the macrostructure of economics RAs. Research questions: 1. Are there any sections frequently used in economics articles apart from the conventional sections? 2. If yes, what are the views of expert economics RA readers on the communicative functions and propositional content of the newly identified sections of economics RAs? Research methods: Eighty RAs were collected from five economics journals using stratified random sampling. Following Yang and Allison's macrostructure analysis method, we conducted an analysis of the overall structure of the RAs based on section headings and the function and content of each section. Results: Compared with the IMRD model, we found six new section types: Background, Theoretical Model, Econometric Model, Robustness, Mechanisms, and Application. Interviews were conducted to explore expert RA readers' genre knowledge on the newly identified sections. Conclusion: The findings can be useful for RA reading and writing instruction and future research on part-genres of economics articles.
