Briefly and concisely define, in your own words, five of the following six concepts [2-3 sentences should do]:

• bid rent curve (Alonso)
  
• spatial iso-outlay line (or spatial iso-cost curve) (Moses)
  
• locational rent function (Thünen)
  
• isodapane (Weber)
  
• spatial demand cone (curve) (Lösch)
  
• spatial margin of profitability

Select one of questions 1-3 for a thoughtful statement in which you should make an attempt to demonstrate

• your understanding and appreciation of a theoretical / explanatory approach to economic Geography and
• what you have learned during these first four weeks through your readings (i.e. NOT what you could have written without taking this class).
• that you have sharpened your deductive skills and are able to apply them to the formulation of locational and spatial-organizational expectations and hypotheses.

1. Select two of the concepts listed in Part I for a more detailed and comparative analysis. First, explain the nature and theoretical functions of the two concepts (without repeating what you have said in Part I) and then compare their auxiliary role in deriving deductive insights about spatial structures.
2. You had a chance to build on your introductory exposure to classical location theories: Given the partial, constrained nature of the individual theories, can you make the point that the different theories complement each other, and that they, together, provide a more general theoretical picture of the spatial organization of the economy and society?
3. You have read Helfgott's paper on the demise of the long-run which introduced you to alternative time horizons in economic theorizing. Given our geographic and locational objectives in this class, would you conclude that there is a need to differentiate such time horizons in locational analysis? If yes or no, why so? Would the paper's conclusions be applicable to locational theorizing?
