Geog. 361. THE ECONOMIC GEOGRAPHY OF ECONOMIC ACTIVITY
QUESTIONS FROM MID-TERM HOUR EXAMINATIONS

Covers through Spring, 1997; more recently used ones are toward the bottom

Answer fifty points worth of questions. Responses to more than the assigned number of points will be scaled downward proportionally. Thus, if you attempt sixty points worth of questions and successfully answer forty your recorded score will be twenty-two ((50/60)*50=33.3). Your time likely will have been better spent concentrating on the specified number of questions. When you are finished, write your name on this exam, encircle the numbers of the questions you chose to answer (and want me to grade) and submit it with your responses.

Quest. No.; Point Value; Question or Challenge

  1. 10 pts. What do market analysts implicitly assume when they employ Thiessen polygons? What problems do they confront reconciling real-word data and the geographies according to which they are collected with these simplistic spatial constructs?
  2. 10 pts. How is the economic notion of "demand" translated into expected sales in landscape contests?
  3. 10 pts. What differences might one see between operations of independent retailers and operations of franchises offering similar assortments of goods?
  4. 10 pts. In what ways does consumer behavior influence locational decisions of retailers?
  5. 10 pts. How might regional growth of population and/or income influence location decisions by retailers? What are the likely impacts on landscapes of rising consumer demand?
  6. 10 pts. The authors discuss "retail hierarchies." What are they, and how are they related to "urban hierarchies?"
  7. 10 pts. Justify the following retailing innovations: 1)$supermarket; 2)$department store; 3)$shopping center.
  8. 10 pts. Under what circumstances might retailers seek "geographical monopolies?" How does that locational decision differ from those of operators practicing "monopolistic competition?" Why are they different?
  9. 10 pts. Describe the geographic arrangement of sales likely to be generated within concentric annuli centered on an isolated vender. Assuming the hypothetical landscape developed in class, account for that pattern in terms of varying annular populations and consumer demand as reflected by anticipated numbers of sales to residents of each annulus.
  10. 8 pts. What consequences has the several-decade-long trend toward dispersal of urban populations had on retail patterns in North American cities?
  11. 6 pts. How do scale economies and prices of goods interact to determine venders' profitabilities?
  12. 10 pts. Woodfield Mall has a very thoughtfully designed floor plan. Prior to the arrival of Nordstrom's its four major "anchors" (Sear's (S), Marshall Field's (MF), Lord and Taylor (L&T) and Penny's (P) occupied key locations at ends of perpendicularly intersecting hallways (illustrated below).
                                     L&T
                                      |
                                      |
                      S---------------+------------P

                                      MF
    Dozens of smaller, specialty stores (mens'/womens'/children's clothing, jewelry and accessories, books, toys, etc.) are strung along the major halls connecting them. Justify such a pattern of store locations. How does that arrangement differ from the usual geography of retailing in a major metropolitan center?
  13. 6 pts. What role is played by grain-eleveator operators and other collectors of agricultural produce in the context of central place theory? How does their presence influence the geometry of settlement patterns in rural landscapes?
  14. 10 pts. How does changing mobility influence consumer behavior? How might it benefit some retail operators (and who might they be) while hurting others (and who might they be)? How might increasing mobility for society as a whole affect the "mobility challenged" (and who might they be)?
  15. 8 pts. Describe the development and use of a "site-ranking scheme" for site-selection decision making. What sorts of variables might be taken into account? What is the purpose of weighting observations on the selected variables? How might those weights be manipulated by development/operations multipliers? How are the developed site rankings employed?
  16. 8 pts. Below is the outcome of a "stepwise regression analysis" of numerous site and situation variables included in a study of store performance by a convenience-store chain.
    Central city sites
    Y = $5,792 + 34.45a - 32.33b - 351.11c + 176.29d
        where:  Y = weekly sales; coefficients of determination in parentheses
                a = percentage apartments within 1/2 mile (0.297)
                b = percentage customers who are pedestrians (0.523)
                c = car accessibility (0.658)
                d = number of competitors with three blocks (0.693)
    Interpret these results.
  17. 4 pts. In class, Prof. T. commented that the coefficients for the last two terms in the above predictive equation seemed counter intuitive, but after further reflection thinks that that outcome might not be so unreasonable. Justify his change of mind by describing a neighborhood or community environment in which these four "most important" contributing independent variables might receive the coefficients shown above.
  18. 8 pts. The "gravity model" has shown up in one form or another in chapters 4, 9 (the Huff model) and 11 (the spatial interaction model). What are the basic elements of these models and of what use are they to understanding the retail environment?
  19. 6 pts. In what ways do chain operations differ from independent retailers?
