Then the number of people traveling inward at any point is the difference between the cumulative number of jobs located up to that point and the cumulative number of workers living up to that point. • Proof: if the number of inward travelers at distance (t) is less than this difference then not all jobs up to t are being filled. If the reverse, then there are more commuters than jobs up to t and jobs beyond t are not being filled. • Implication: jobs must be more centralized than residences for positive traffic flow in the allowed direction. • With complete job-residence dispersal: no commuting! • With centralized employment traffic worst at the edge of the business district enter for Real EMIT C state F ig u re 4: L an d U se an d T ravel C o sts, 2 m illio n in h ab itan ts, m ixed u se city, h igh ag g lo m eratio n 1.2 500 450 % of Total 1 400 350 0.8 300 0.6 250 200 0.4 150 100 0.2 50 0 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 Dista nce (1/10 M ile) Cum ulative E m ploym ent Cum ulative P opulation Travel Costs/mile Figure 6: Land Use and Travel Costs, 2 million inhabitants, mixed use city, low agglomeration 0 1 0 50 0.2 0.4 0.6 0.8 1.2 % of Total 100 150 200 250 300 350 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 Distance (1/10 Mile) Cumulative Employment cum ulative Population Travel Costs/m ile [...]... to secure workers = higher travel costs erode the suburban wage advantage • Is the CBD the site with best access to all type of Workers in the region?

Why firms leave the CBD for a Subcenter • Subcenter workers at d5 pay the same for land as CBD workers living there, but have a shorter commute Hence their wage must be less by the difference in commute: (d5 – d1 ) versus (d2 – d5 ) • Note that land rents still make workers that are employed at each center indifferent about living at different locations around that center • Firms at the CBD now must... cannot contract in the face of suburban competition (its capital is fixed) - Mobile workers will still demand higher wages to work there - Rents will contract and remain below replacement costs to attract tenants who must pay higher wages - Eventually space will deteriorate and not be replaced MIT Center for Real Estate The same argument is at work within central cities The stock of office space is... Real Estate What if zoning limits the amount of commercial space at a “good” location • The center with lower wages is supposed to grow and expand until its advantage is eventually eroded through longer commutes (and higher wages) • Without this growth, its advantage will remain and without greater commuting, wages will remain lower – hence Rents will rise to absorb the advantage • What will happen... commercial land zoning MIT Center for Real Estate Boston Office Market: Nodularity and the distribution of subcenters Office Area, Buildings, and Asking Rents, Boston-Area Towns, 1993, CBRE Town (Cluster Square Feet (thousands) Number of Buildings Rent Back Bay 10,675 66 25.19 Financial District 26,754 141 26.73 South Station 3,053 21 23.50 Andover 1,438 10 16.25 Burlington 3,498 43 18.90 Cambridge 11,103...

(Archer-Smith, 2003) • Yes, if residential rents are higher from longer commutes • But that necessitates an offsetting agglomeration or other advantage (how to distinguish between the two?) • No if larger subcenters have better transport systems (that’s what makes them larger) • Yes, if as centers grow, they bump up against boundary... higher land rent (equal here to residential), but must also pay higher wages for labor - Wages: 15% more [e.g $13,500] - Rent (per worker): 250 x $15-20 [e.g $4250] MIT Center for Real Estate MIT study of wages and average commuting time by location of employment [POWPUMA] MIT Center for Real Estate Why not a Fully Dispersed Polycentric City?
