Space and Time Analysis of the Knowledge Production Function
نویسنده
چکیده
Research and development-based growth models aim to explain the role of technological progress in the growth process. The role of knowledge production and intertemporal spillover effects are investigated using a panel data set covering 49 US states over the period 1994-2004. The aim is to estimate knowledge flows in the context of a space-time dynamic suggested by the knowledge production function. A space-time specification is set forth that can be applied to panel data models with random effects. We compare models that have been proposed recently in the panel data literature to provide a better understanding of how new ideas diffuse across space and time. The results indicate that strong intertemporal knowledge spillovers are present. These results are interpreted in light of the existing theoretical and empirical literature on endogenous growth.

Spatial Representation and Production and Reproduction of the Mental Image: Lefebvre’s Trialectic Approach
Lefebvre's theory of space production has been very much considered. In particular, it is important to integrate it systematically into the categories of city and space as a comprehensive and comprehensible social theory. Lefebvre's theory of space production has been remarkable in recent years and has responded well to the many questions posed in the early 1970s. Lefebvre in his trialectic in ...
متن کاملDimensional Similarity in the Study of Microbubble Production Inside Venturi Tube
The present study considers of the water and air flow and Micro-Bubble production inside the venturi tube, by the use of dimensional analysis. Numerical analysis of Micro-Bubble creation in venturi tube requires fast computers and large amounts of storage space. Up to now, there has been no numerical analysis concerning Micro-Bubble creation and all other existing studies are experimental. To s...
متن کاملAn iterative method for forecasting most probable point of stochastic demand
The demand forecasting is essential for all production and non-production systems. However, nowadays there are only few researches on this area. Most of researches somehow benefited from simulation in the conditions of demand uncertainty. But this paper presents an iterative method to find most probable stochastic demand point with normally distributed and independent variables of n-dime...

Because of the limited capacity of coastal lands and conflicting interests among stakeholders for coastal resources, there are intensifying pressures to retain and provide more public access to the coast. Coastal gated communities have been developed increasingly in the middle shoreline of Caspian Sea in North of Iran. They are kind of exclusive space production as they restrict public access t...
