What is the Location Equilibrium equation?
Wages (W) + Amenities (A) ‐ Housing Costs (H) = Constant (C)
What happens to Wages (W) if Amenities (A) increase to 400?
500 + 250 – 400 = C
Wages decrease by 500 – 350 = 150

Estimating the value of amenities
Why does specialization exist?
because comparitive advantages separates people's opportunity costs
What are two economic reasons that cities exist?
they allow people to specialize and trade
economies of scale
Define the theory behind Economies of Scale.
average costs fall as output increases
What kind of cities would be considered Type 1 cities?
old Western cities
specializaton and trade cities
What kind of cities would be Type 2 cities?
Economies of Scale in Transportation cities
Erie Canal cities
What kind of cities would be Factory Towns?
Economies of Scale in Production
What is the reasoning behind consumer cities?
as consumption increases, average cost decreases
What are some natural advantages that explain why cities pop up?
What is a portage?
a transfer city from a waterway to a rail or roadway of increasing elevation
Discern a natural resource extraction in the case of Pittsburgh.
Iron ore is the natural resource to make the finished product of steel
What is the distance formula for production location?
price of input/cost per mile
What are the two types of firm clusters?
urbanization- indifferent firms cluster
localization- similar firms cluster
Why do Final Good producers share intermediate inputs?
to save on shipping costs
access for face to face meetings
modification costs- save on changing product
What are the benefits of labor matching?
more workers=more variety of worker skills
better match for skills you need
don't have to train as much
improving the production process through knowledge informally
What was the problem with Ed Glaesar's Localization theory?
selection problem- those willing to move will earn higher wages for other reasons
Explain Michael Greenstone's explanation to Localization.
The effects of clustering- a huge new factory increases the productivity of nearby firms by labor pooling and knowledge spillover effects
WHat are some reasons firms benefit from localization?
servicing corporate headquarters
joint labor supply decisions
WHat two groups did Matthew Kahn use to explain Localization?
power couples and singles
What are the offsetting effects to consumers' wants according to retail agglomeration?

Market-Size Effect-the chances consumers find what they want increases
What did Ernest Basker want to prove in retail agglomeration?
Wal-Mart has a huge, positive effect on employment around it
However, Basker picked places where employment would have increases without a Wal-Mart (selection effect)
