Geography 207 Winter 1995

MIDTERM EXAMINATION

Total Points: 60

INSTRUCTIONS: You will have the full class time to complete this 60 minute-examination. Thus, take your time and think carefully before you select and answer the questions. Choose your questions so as to be able to avoid unnecessary repetitions. You may want to construct rough outlines for all your answers before you begin with your concise and well-organized writing. We will not be embarrassed if you use concepts and ideas covered in class or the readings, even if they are not specifically asked for (as long as they are appropriate for the purpose at hand). Please do not harm your neighbor with your gigantic Notebook. Enjoy your intellectual thrills.

Select one question from each of the following four parts (15 minutes or points each):

PART I: (a) Juliet Schor, in her Book The Overworked American estimates that between 1969 and 1987 (fully employed) Americans have increased their total annual work hours on the average by about 160 hours. Without knowing any further details and assuming that these estimates are just about correct, develop some (deductive) propositions as to what kinds of changes in daily living, commuting and working patterns you would expect to find in association with (and in part as a result of) such increases.

or: (b) Assuming you are on the long-range planning staff in the Governor's Office, where would you be looking (and why?) for early warning signs for the kinds of changes or developments which would require timely policy and planning preparations?

PART II: As an aspiring Economic Geographer (not just as an economist), relate the following two concepts to each other: Select either (a) "complexity" to "structure" or (b) "Engel's Law" to "Three-Sector Hypothesis"

PART III: Select either (a) "A discussion of the diverse changes constantly occurring in patterns of location and spatial distribution can be conceptually reduced to a discussion of processes of spatial centralization (agglomeration) and de-centralization (dispersion)." Do you agree? Discuss. or (b) Use your understanding of spatial (i.e. 'space-differentiating') forces, your deductive skills and your imagination to suggest what vertical variations in space use you would expect to find within a tall Manhattan skyscraper with an elderly (slow) elevator system (and, of course, why). or (c) Why is it so difficult to find food stores in downtowns of large American cities?

PART IV: Select either (a) How can our conceptual 207- framework (or, alternatively, the framework of a specific Economic Geography text (which?) be adjusted to your field of concentration? or (b) Since our questions were obviously too easy for you, here is your chance: Formulate a question related to class materials which is sufficiently "sophisticated" that its answer will show the true depth of your understanding. You will be graded on the basis of the quality of both, the question and the response (including the relative lack of overlap with any of your other answers).

BONUS: What does (1) NAFTA and (2) UWIN stand for? Who are/were these gentlemen: (3) N.D. Kondratieff and (4) Gary Becker? Approx. size of the (5) U.S. 'GNP' OR 'GDP', AND THE (6) U.S. monthly trade deficit? (7) Capital of Croatia? (8) Estimated cost of the planned Puget Sound Area Light Rail System? (9) What is a 'spatial demand curve'? (10) How many states would need to pass the balanced budget amendment to the U.S. Constitution for it to be ratified.



Midterm 207 / 1994




Subject: Midterm (Some possible answers)

1. A few of you still have to pick their midterms (during my office hours M or W from 1-2). Show that you are interested in this feedback!

2. The midterm is mainly a diagnostic tool. If you want to have some expert interpretation of your answers and results, you need to take the initiative and see us. Bring the midterm!

3. Now is the time to correct any possibly existing "bad habits" and get organized for the end-run. Reread all instructions and guidelines in the (extended) syllabus, identify all gaps in your notes, excerpts, hand- outs and readings and begin to fill them, systematically collect and formulate questions related to class materials and begin to formulate outlines for the answers; if you have not done so: make contact with other motivated students in the class as well as with TA, and, last not least, pencil-in some 207-related activity for every day in your calendar between now and the date of your "Last Rites".

4. Quite a number of you wrote quite decent answers to questions which we did not always recognize. In the final examination, there will need to be more emphasis on fitting answers to questions!


SUGGESTIONS FOR POSSIBLE ANSWERS:

Part I:
1. Explain Ullman's concept of "complementarity" as one of the bases for spatial interaction.

Comments: See Package, mimeographed excerpt from Ullman's original article, supplemented by readings from other texts. Look under "Ullman" in Index. e.g. Dicken Lloyd, 3rd ed., pp.71ff.

2. What is meant by "forward" and "backward" linkages in Industrial Geography, e.g. in an "input-output model" or in Weber's theory of location? Comments: see textbook, Index, class notes

3. Explain Torsten Hagerstrand's concept of "coupling constraints" in the context of his time-space prism analysis.

Comments: Package, excerpt from Modern Western Society (Dicken + Lloyd). [Here we asked ONLY for coupling constraints and their significance]


4. What is meant by "Terms of Trade"? Could this concept make sense also for transactions other than those involving international trade?

Comments: Terms of trade do NOT refer to contractual conditions of trade, but to price or exchange relationships between exports and imports. Thus, terms of trade improve when the prices for exports increase or those for imports decrease. Yes, the concepts of terms of trade can be meaningfully applied to many exchange type interactions. The "terms of trade" have lately badly deteriorated for UW students who are facing relatively stable hourly wage rates but rapidly increasing tuition costs.

5. Package, class discussions

6.Harold Hotelling wrote a well-known paper in 1929 on "Stability in Competition." What would happen to his famous "ice-cream-vendors-on-the beach" solution ("equilibrium") if a third vendor would enter the scene?

Comments: The 3rd competitor, under rigorous conditions, will crowd-in one of the other two competitors who will then jump and start a musical chair dance up and down the beach: No stable equilibrium solution is possible. (Unless one would build-in a function for tiring out or increasing muscle aches or decreasing competitive spirit and willingness to sit down over a beer and divide up the market -- hoping that the Justice Department will not hear about it).


7. Explain the concepts of the "Threshold Range" and the "Range of a Good" of service and briefly identify the significance of these concepts for market-area analyses.

Comments: Threshold range refers to the minimum (or maximum) market area which a supplier needs (or can sell to) to make his undertaking viable. The range of a good refers mainly to the demand side and is defined by the maximum distance consumers are willing to travel (or pay transport costs for) for a good or service at a given f.o.b. price at the point of supply. The significance of these concepts relates to the equilibrium conditions for market areas. (i.e. what kinds of market areas we would expect under defined conditions). What is important here is that these concepts allow us to introduce the full gamut of supply-side (cost) and demand considerations and differentiations, related to the the particular product and its production/supply as well as differences in preferences and ability to pay among consumers as well as differences in transport costs and demand densities.


8. Explain how our knowledge of income elasticities of demand for a particular service would affect our expectations as to the size and spatial structure of the market area of that service.

Comments: Relatively high income elasticities (demand increases possibly more than proportionally with income levels of households) might mean the existence of services in wealthy peripheral areas which you may not find at more central locations (especially, of course, if thresholds are relatively small). What would otherwise be important is how the price elasticity of demand relates to the income elasticity. A good may have an unusually large range if these higher income households have a low distance+price elasticity of demand. That might result in the viability of services in the center which otherwise would not be able to survive. A supplier who would not have to fear competition might then locate close to poorer people with high distance elasticities knowing that the wealthier people will come anyway from longer distances. [We also referred to an "income elasticity of the distance elasticity of demand"; also: a reference to Engel's law type of demand phenomena would not have been inappropriate]


9. What might Economic Geographers mean by 'complexity' in the description of the 'real world'.

Comments: We referred to various attributes of complex systems in class, including size, diversity, indirectness of linkages, inter-connectedness within a firm's environment (possibly giving rise to hostile collusion). See also chapter on complexity in package.


10. Make a case for the thesis that "Small is Beautiful", not on the basis of internal diseconomies scale (or diminishing returns), but instead with reference to internal or external "Diseconomies of Scope".

Comments: Scope economies refer to savings or cost reductions associated with diversity or range of different inputs, technologies, outputs of an activity. Diseconomies might then refer to "overload", frictions between different components (skills, personalities, technologies, chemicals, organizational styles etc.) or, in an external context, excessive scope leading to perceived complexity leading to lack of public understanding; inappropriateness of infrastructure, public frictions resulting from excessive diversity... or, generally, as one of you pointed out, the disadvantages of having too many "jacks-of-all-trades" running around.

11. Need for conceptual frameworks: see extensive earlier e-mail message.

12. Consult what should be your quite extensive class notes. Make distinction between cargo (interest, urgency, reliability, JIT etc.) and passengers (lost work or leisure time) and the investments in transport facilities and equipment (interest on capital invested, rate of depreciation over time through actual use, even through idleness or through technological obsolescence) and finally other time related costs: salaries of pilots etc.


13. Networks: Most of you had very little trouble with designing networks and calculating their Beta values. Most of you recognized that Beta is a measure of connectivity, but many did not make a distinction between accessibility (as an attribute of a node and a measure of its locational/situational quality) and connectivity (as an attribute of a network and measure of its interconnectedness). The question than is how does one particular existing link (or an additional link) affect the accessibility of specific nodes (from or to other nodes) and, with the help of the BETA Index: how does the connectivity of the whole network change by taking out a link or add a new one? The salesman location problem obviously depended on the configuration of your specific network. In general you would have looked for the node which is best connected to itself via all other nodes. With this question, I tried to link Hagerstrand's time/space conceptual model to a more operational model (but you did not have to refer to Hagerstrand!)


Question 14: BRANCH CAMPUS

Many of you discussed the difficulty of assessing demand for the branch campus in terms of the demographic dynamics of commuter student and mentioned uncertainties regarding the size, distribution, and mobility of the commuter student population, including those presently enrolled in the UW as well as those who would now attend college because of its availability. They also mentioned the population growth of the suburbs which adds to the complexity of predicting future demand.

Less common were answers that dealt with the trade-offs between the size and and scope (economies and diseconomies) of the main campus, the accessibility (distance) for students and staff and possibly lower land costs for the branch. Factors such as the mixing of UW campus identities, prestige benefits, shared resources, and the potential for unnecessary duplication were mentioned by some students. Some students also discussed the problem of defining the optimal level of justifiable fixed or overhead costs when the branch campus is somewhat of an auxiliary campus rather than a discrete entity. Finally, a few students recognized that the location of the branch had to be such that it would best serve new student populations or unmet needs among the existing population without actually competing with the UW main campus for students or resources.
The difficulties of evaluating & comparing the "output", i.e. education quality and quantity in dollar terms sufficient to make rigorous location decisions based on (external) agglomeration- and internal scale- and scope economies and diseconomies could also have been mentioned among many other considerations. In general then, the "difficulty" is related at least to these factors: (a) measure of (intangible) output (different qualities of B.A.'s) (b) assessing the distance elasticity of demand for education in general, and branch campus education in particular. (incl. the question whether proximity to jobs or residence is more important for working students) (c) lack of understanding of the interdependencies on a campus between different departments (if you cannot have them all, which ones are most important for the whole (d) lack of understanding of how large and internally diverse individual departments ought to be (e) who all these questions relate to distance to the main campus and so on...

Question 15: LARGE CITY/SMALL CITY or LARGE MALL/SMALL MALL

You were more inclined to conclude that small cities and malls benefit from close proximity to their larger neighbors. While the explanations for this conclusion were generally well supported, few identified the costs of leakage to and market dominance by the larger city/mall. This question, in particular, was susceptible to empirical example answers with relatively little theoretical or conceptual thought. The question was formulated in a way which should have made it easy for you to relate it to the (at least in part) countervailing forces of attraction/positive spillovers/ agglomeration economies (suggesting advantages of proximity) and the competitive superiority of the large city crowding out the small city as a market center. Researchers have suggested that there tends to be a distance from the large city where a small city is worst off, namely there where the spillover-agglomeration economies are flattening out and where the benefits of carving out a market-hinterland more or less detached from that of the big city are not yet high enough to compensate.

Always ask yourself the question: How far can I go in answering the question by logic alone, deriving what you would expect to find before relying on your casual, incomplete and possibly biased own real-world observations or on (generally) expensive empirical surveys which may provide a lot facts and statistical associations but possibly very little explanation.

QUESTION 16: GOLF COURSES

Only few of you selected this question, and few seemed to get to the heart of the matter. It seemed rather obvious that the downtown course would need to charge higher rents based on accessibility to justify its equal consumption of space. Some simply evaded this answer by changing the facts and explaining that the suburban golf course was more justified in its location decision, or that it was appropriate for the center-city golf course to move to the suburban location. You could have used the obvious and palpable example of apartments of the same size with different rents depending on whether they are in downtown Seattle or Federal Way. Clearly, the same size of golf-course does not imply that the (land) use is equally "intensive" in that either the downtown course is used by more people or better taken care of in combination with use by higher-income people whose cost of time, cost of fancy equipment etc. is higher. While we could of course argue that downtown 18-hole courses would tend to use less land (and likely find this in reality), all you need to get theoretically larger downtown courses is to assume sufficient income differences and a strong preference of downtown executives for lunch-time golfing. Money can buy it all...

QUESTION 17: TSH

Most of you who answered this question made reference to changing technology or capital substitution for labor in explaining the evolution of the sectoral employment shares. Fewer students then added that higher productivity has led to more leisure time, higher income, Engel's law and a consumption-based economy wherein tertiary services and consumer goods play a more important role. As for the second portion of the question addressing employment shifts between regions and firms, only few were able to reach the spatial division of labor and restructuring arguments that would explain such shifts. We could have turned this question around and asked: what is needed for a region or firm or farm to keep up with the Jones in terms of gross regional product or income. Do the same forces have to be taken into account? (Yes!) What does a firm or farm have to do to continue operations even though it is running out of productivity increase possibilities or marketing gimmicks: Switch to other products, or crops or relocate activities to locations where labor is still willing and able to work at a certain wage or productivity level and/or were the demand is still there. Thus many "manufacturing" firms have become largely service firms (think of the clothing "industry" in Seattle) and/or are manufacturing now largely abroad. G.K.

I hope you find these observations helpful. Please notify me if you have further questions -
