Standard economic doctrine makes assumptions of rationality that have very strong implications for the complexity of individuals' decision processes. The most complete assumptions of competitive general equilibrium theory require that all future and contingent prices exist and be known. In fact, of course, not all these markets exist. The incompleteness of markets has several side consequences for rationality. For one thing, each decision maker has to have a model that predicts the future spot prices. This is an informational burden of an entirely different magnitude than simply optimizing at known prices. It involves all the complexity of rational analysis of data and contradicts the much-praised informational economy of the price system. It is also the case that equilibria become much less well defined. Similar problems occur with imperfect competition.
The Journal of Business ceased publication with the November 2006 issue (Volume 79, Number 6). Founded in 1928, The Journal of Business was the first scholarly journal to focus on business-related research and played a pioneering role in fostering serious academic research about business. However, in appreciation of the increasing specialization in business scholarship, as reflected in the emergence of many specialized business journals, the faculty of the University of Chicago's Graduate School of Business decided after careful deliberation and extensive dialogue to cease publication of the more broadly focused Journal at the end of 2006, after nearly eight decades of publication by the University of Chicago Press.
Since its origins in 1890 as one of the three main divisions of the University of Chicago, The University of Chicago Press has embraced as its mission the obligation to disseminate scholarship of the highest standard and to publish serious works that promote education, foster public understanding, and enrich cultural life. Today, the Journals Division publishes more than 70 journals and hardcover serials, in a wide range of academic disciplines, including the social sciences, the humanities, education, the biological and medical sciences, and the physical sciences.
