This issue of the Journal of Financial Economics contains the first set of studies in the new Clinical Papers section. The objective of this section is to provide a high-quality professional outlet for scholarly studies of specific cases, events, practices, and specialized applications. By supplying insights about the world, challenging accepted theory, and using unique sources of data, clinical studies stand on their own as an important medium of research. Like the medical literature from which the term 'clinical' is borrowed, these articles will frequently deal with individual situations or small numbers of cases of special interest. The JFE intends to take a leading role in encouraging clinical studies, guided by the confidence that expanding our research agenda and providing an outlet for this work will enliven and enrich professional knowledge. We expect these clinical studies to stimulate new high-quality empirical and theoretical research,Innovation in financing techniques, deregulation, reregulation, and changes in the organization and conduct of commerce are proceeding at a rapid rate. New products and practices are appearing constantly, and the roles and activities of financial institutions are changing dramatically. New ways to communicate these interesting changes to the scientific community are required because the changes provide tests of leading theories and suggest new problems of theoretical interest. Clinical papers, inspired primarily by actual events, can play an important role in this discovery and communication process and, therefore, in the evolution of the science of finance.The advantages of specialization imply that different groups of researchers will tend to concentrate on theory, empirical tests, and clinical studies. These three groups complement each other. Theory provides logical discipline and precise hypotheses for both empirical and clinical research. Empirical tests direct theorists by identifying irrelevant models and suggest where clinical research might find counterexamples. Clinical studies help set the agenda for both theory and empirical work. Because of this complementarity and the importance of communication between these groups, the Journal of Financial Economics is committed to publishing all three types of research
