Critical discourse analysis and critical policy studies

This article presents the contribution that critical discourse analysis (CDA) can make to critical policy studies through comparison with two other approaches which also advocate a 'discursive turn' in policy studies and that have been discussed in the journal: cultural political economy (CPE), and poststructuralist discourse analysis (PDA). I suggest that there are significant differences between CDA, CPE and PDA in their view of the discursive turn, and that a version of CDA which integrates argumentation theory and analysis with CDA can add significantly to the contributions that CPE and PDA might make to policy analysis. In the Conclusion, I address a suspicion that using argumentation analysis entails a commitment to Habermasian/Rawlsian 'deliberative democracy,' suggesting that argumentation analysis is also not only consistent with but also necessary for Gramscian approaches to political and policy analysis, including CPE and PDA.
