Geography 1400F/G Lecture Notes - Lecture 3: Effective Demand, Distance Decay, Spacetime
Document Summary
Spatial interaction: the movement of people, ideas, and commodities. Spatial differences (ex: relationship between supply and demand) Supply and demand >> must be existing of effective demand: transferability. Underlining conditions of transferability: product features and values, distance in time and money, costs of movement, intervening opportunities. Obstacles to the flow of goods, services, and people. Level of interaction between places is influenced by distance. How: in terms of time, in terms of costs. That is, dd >> decline in an activity with increasing distance from point of origin. Why: due to innovation in transportation and communications, improvement in friction of distance i. e. time-space convergence. Aspects of mobility behavior: circulation daily routines, migration permanent relation to a new location. Territoriality: delineating spaces into territories by individuals and groups. Spaces we share with other people on regular basis. Stage in life course i. e. age groups. Means of mobility i. e. resources at individual disposal (ex: income)
