The need for legislative information and research, especially in developing and transition countries, is growing as policy-making processes become more complex, particularly in the context of globalisation, regional integration and decentralisation. Since the executive branch of governments generally has access to a larger pool of knowledge and expertise than the national legislature, there is a need to address the imbalance in access to knowledge between the executive, legislature and judiciary in order to promote better quality policy-making. Better access to information and research can help empower legislatures to formulate and pass effective legislation and perform effective scrutiny of government. Using the Research and Policy in Development (RAPID) framework, this study maps the links between researchers and legislators in a number of transition and developing countries; explores the role of politics in influencing researcher–legislator linkages; and comments on the type of research produced as well as the credibility of the research/researchers.
