In the summer of 1992 a group of molecular, population and evolutionary geneticists assembled on the campus of the University of Georgia in Athens, USA, to discuss the relevance of their research to the role played by transposable elements (TEs) in evolution. The meeting consisted of a series of informal discussions of issues brought up in papers written by the participants and distributed among them prior to the meeting. These papers and the transcripts of the ensuing discussions are presented in this volume.

Once considered merely `selfish' or `parasitic' DNA, transposable elements are today recognized as being of major biological significance. Not only are these elements a major source of mutation, they have contributed both directly and indirectly to the evolution of genome structure and function. On October 8-10, 1999, 100 molecular biologists and evolutionists representing 11 countries met on the campus of The University of Georgia in Athens for the inaugural Georgia Genetics Symposium. The topics of presentations ranged from how the elements themselves have evolved to the impact transposable elements have had on the evolution of their host genomes. The papers in this volume therefore represent state-of-the-art thinking, by leading world experts in the field, on the evolutionary significance of transposable elements.

Offering an examination of the relationship between congestion tolls and highway capacity in the long run, this study breaks new ground in the economic theory of optimal road capacity by including theoretical contributions, empirical studies, and simulation experiments that all pertain to the general topic reflected in the title. The book is organized into four sections: 1) highway traffic flow; 2) commuter choice of tollways versus freeways; 3) congestion pricing in the short run; and 4) road capacity and pricing in the long run. In particular, the first section on highway traffic flow examines the chief models and empirical studies of vehicular flow on urban highways. The second section of the book is a theoretical and empirical examination of the choice that commuters make between urban tollways and freeways. The third section is devoted to congestion pricing in the short run, the time period in which the urban highway facilities are taken as given. This section is the most important part of the book from the standpoint of public policy.The fourth and last section of the book considers road capacity and pricing in the long run, with the concluding chapter gathering the authors' main results in one place and making recommendations both for current policy and for future research.

Economics of Urban Highway Congestion and Pricing offers the most extensive examination to date of the relationship between congestion tolls and highway capacity in the long run.
