Rabbits and agriculture in post-medieval England

Rabbit-warrens may have represented the optimal use of very light soils. The paper relates the status and management of rabbit-warrens to the agricultural environment and improvements of post-medieval England, and describes the stages by which an alien species became established as a significant pest by the early modern period.     

Demand in the Spatial Economy: II Homo Stochasticus

Probabilistic preferences and choices and their connections to trip making and to distance-related demand are discussed. They are seen to aid aggregation. Risk aversion in retail shopping behavior and entropy maximizing as rational random behavior are examined. Elasticity of substitution is presented in terms of the covariance matrix. A Markovian phrasing and potential theory allow an analogy with deterministic choice: various applications of potential operators are outlined. Changes in utilities can only be modeled stochastically and some mechanisms are detailed. Price changes are random walked in time and space as a diffusion process. A fairly coherent theory of spatial demand emerges
