Optimization of the part of consumers is shown to imply that the marginal utility of consumption evolves according to a random walk with trend. To a reasonable approximation, consumption itself should evolve in the same way. In particular, no variable...

returns to R&D and then proceeds to discuss in turn two very difficult problems: the measurement of output in R&D intensive industries and the definition and measurement of the stock of R&D "capital." The latter concept leads to a discussion of modeling...

The article presents an overview of the longitudinal-processual theory of organizational formation. The ideological underpinnings of the method are described, highlighting its central focus on the factors and elements of an organization's creation and...
