Abstract
Critical discourse analysis (CDA) and other forms of discourse analysis are regularly used to study identity, but rarely do researchers systematically compare and contrast them with other theories to identify exactly what a discursive approach contributes. In this paper, we take the example of a particular identity – the older worker – and systematically compare the contribution of CDA with other approaches, including economics, labour market research, gerontology and cultural studies. In so doing, we show the kinds of research questions that CDA can address, which other theories grappling with identity cannot. In this way, we hope to delineate more clearly what CDA is, to identify specifically how it contributes to the study of identity, and to show what it can do, compared to other theories.
