Book Description
This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogenous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or industrial innovations. This has both positive and normative implications for growth. In positive terms, the prospect of a high level of research in the future can deter research today by threatening the fruits of that research with rapid obsolescence. In normative terms, obsolescence creates a negative externality from innovations, and hence a tendency for laissez-faire economies to generate too many innovations, i.e too much growth. This "business-stealing" effect is partly compensated by the fact that innovations tend to be too small under laissez-faire. The model possesses a unique balanced growth equilibrium in which the log of GNP follows a random walk with drift. The size of the drift is the average growth rate of the economy and it is endogenous to the model ; in particular it depends on the size and likelihood of innovations resulting from research and also on the degree of market power available to an innovator.

Book Description
This volume is based on the recognition that heritage is popular and popular culture is now readily transformed into heritage, whose meanings and myths reshape social life and political and economic realities, as well as re-make "tradition". The papers in this volume consider: What does popular heritage look like? To whom does it speak? Is it active in dissolving class and cultural boundaries or just in reproducing new ones? How do societies manage a heritage that is fluid, immediate and that straddles extremes of serious conflict and hedonistic frivolity? When and under what circumstances is the creation and expression of new cultural forms - popular culture - capable of being transformed into heritage?
