R&D and the Agglomeration of Industries
This paper discusses a model of the New Economic Geography, in which the seminal core-periphery model of Krugman (1991) is extended by endogenous research activities. Beyond the common ’anonymous’ consideration of R&D expenditures within fixed costs, this model introduces vertical product differentiation, which requires services provided by an additional R&D sector. In the context of internatio...
متن کاملDeregulation and R&D in Network Industries: The Case of the Electricity Industry
Implementation of electricity reform has coincided with a significant decline in energy R&D activities. Technical progress is crucial for tackling many energy and environmental issues as well as for long-term efficiency improvement in the sector. This paper reviews the industrial organisation literature on innovation to explore the causes of the decline in energy R&D spending and shows that it ...

The rst of these notes the close connection between the authors random coe¢ cient model and some earlier models that were not formulated in terms of "random coe¢ cients". The second comments on the models identi cation. The third point queries the transition from the authorsbasic model (1) to their quantile version (2). Finally w...

Managing the buffering of data along arcs is a critical part of compiling a synchronous dataflow (SDF) program. This paper shows how dataflow properties can be analyzed at compile-time to make buffering more efficient. Since the target code corresponding to each node of an SDF graph is normally obtained from a hand-optimized library of predefined blocks, the efficiency of data transfer between ...
