# Why do all apartment complexes in Albuquerque have pools?

Apartment builders have a constrained optimization problem whereby they balance building different amenities to attract tenants with varying preferences. Recently when searching for apartments I noticed that every single apartment seemed to have a pool. I feel like many people would prefer a small decrease in rent and open space, more parking, a larger fitness center, ect to a pool. Apartments have many other variances in terms of parking, landscaping, price, ect, yet the pool seemed to be a universal. Does this simply reflect that the apartment market cannot be perfectly competitive or that preferences for pools is near universal? Is there an economic explanation or cognitive bias that would explain this kind of convergence?

PS: I will not be offended if this is closed. I'm not sure if this type of question is not on topic for this site.

• I think it's an interesting question, though the answer is likely to be very case specific, hence it may be closed for not being a good resource to others. My guess: I do not know how many apartments you searched for and how random your sampling of the apartment market was but it could be that the apartments meeting your criteria were all built by development companies that specialize in building generic middle class homes.

• I would suggest that maybe the cost of having and maintaining a pool increases in the cost of water and land. The utility people derive from having access to a pool is increasing in temperature and number of days of sunshine. And, for whatever reason, perhaps Albuquerque has that ideal combination of cheap water, cheap land, high temperatures and high frequency of sunny days. There's at least a testable theory (any of the above statements could be falsified). Jun 4 '15 at 16:40
