Impact of external forces on soil structure in Impact of water and external forces on soil structure. Selected papers of the 1st Workshop on soilphysics and soilmechanics, Hannover 1986.
Several external forces, acting on the structure of soils, including raindrop impact, are briefly discussed. Two external forces are discussed in detail. The first one is a temporary external loading force, caused by the weight of tractors

In a cross-sectional, establishment-level analysis using confidential secondary data, the paper evaluates the influence of commonly postulated sources of localised external economies - supplier access, labour pools and knowledge spillovers
- on the productivity of two US manufacturing sectors. Measures incorporating different distance-decay specifications provide evidence of the spatial extent of the various externality sources.

This paper explores the existence of different types of static and dynamic externalities and shows the relationship between externalities, interregional trade, and cluster policy. First, it contributes to a better characterization of dynamic
externalities by extending the “advantages of backwardness” approach, formerly developed to explain the catching-up of national economies, to the regional conecontext. Second, it presents a new model that relates static and dynamic externalities
regions. The major conclusion is that policy must pursue a combination of the comparative advantage principle with one type of dynamic externalities un-covered in this paper: the “related variety benefits” of agglomeration.
