SPATIAL DISPERSION OF TECHNOLOGICAL INNOVATION: A CASE STUDY FOR THE NETHERLANDS BY MEANS OF PARTIAL LEAST SQUARES*

ABSTRACT. In this paper the impact of spatial and nonspatial variables on the innovation potential and innovativeness of (small) industrial firms in The Netherlands will be analyzed. Innovation potential and innovativeness will be conceived as latent variables which will be measured by a partial least squares approach. The variables reflecting innovation potential are notably input variables such as internal and external R&D, while innovativeness will be based on output indicators such as the number of product and process innovations. The regional dimension enters our analysis essentially at two levels. First, we will investigate whether more innovative firms are to some extent spatially biased (i.e., on the basis of intrafirm characteristics). Secondly, we will analyze the relevance of an indigenous regional impact, per se. In other words, we will examine whether firms with an equal innovation capacity will differ in actual (i.e., realized) innovativeness as a consequence of different regional conditions. For the first issue, our results indicate that not all regions are equally well-endowed with potentially innovative (small) firms. Our analysis even demonstrates that these firms are underrepresented in regions which are generally considered to offer the most favorable production environment. After compensating for these differences in the composition of the regional set of firms, we demonstrate that an indigenous regional impact per se cannot be identified in The Netherlands.     

ANALYSING THE CULTURAL LANDSCAPE AS A MEANS OF PROBING THE NON-MATERIAL DIMENSION OF REALITY

The paper analyses in detail the way in which the spatial organization of settlements and the architectural form of buildings and other structures can be interpreted as the expression of the values and beliefs of the people responsible for them. In doing this, it draws on recent developments in linguistics and physiological psychology. The procedure, while not completely objective, does provide for the presentation of verifiable evidence and the testing of hypotheses.

THE SPATIAL MONOPSONY: A THEORETICAL ANALYSIS*

ABSTRACT. In this paper some of the most important properties of the behavior of a spatial monopsonist are derived. Many results are mirror images of corresponding results for the spatial monopolist. A few results are, however, genuinely new. A lot of effort is spent in comparing the properties of the profit function under three different pricing policies, f.o.b. (mill)-pricing, uniform delivered pricing, and spatial price discrimination. It is shown, for example, how the profitability and welfare consequences of the different policies are related to the shapes of the supply and demand functions. It is argued that the theory may have important applications in economic analyses of renewable natural resources such as forests, where total transportation costs are nonnegligible.     

THE MAXIMUM CAPTURE PROBLEM IN A WEIGHTED NETWORK*

ABSTRACT. In this paper, a conditional location problem on a weighted network is examined. Attraction functions are defined and the problem is formulated as a mixed integer program. A method which simultaneously locates an additional facility on the given network and optimizes its weight is then described. A numerical example is provided.
