N1  - Includes bibliographical references and index
N2  - There are three major themes of this text book: first, an attempt to explain what economic theory is about and how one can go about criticizing it effectively and hence improving it; second, an attempt to elaborate, in so far as is possible within the confines of an introduction to economic theory, the relation between theory and real-world  observations; and third, a consideration of the relation between economic theory and economic policy
