I studied the CEMEX model in an MBA course I took last semester. You bring up a great question- I definitely think this model could be applied to other industries. For auto manufacturers it might be tricky in the U.S. because manufacturers don't sell directly to customers, instead they go through auto dealerships. Dealers do offer financing plans to help customers, but not in any way that harnesses the power of a community. There is definitely a need for auto manufacturers/dealers to rethink their selling model now that Tesla is starting to fundamentally change how cars are bought and sold. I could see something similar to the CEMEX model working in electronics and furniture, or even for small-scale fishermen. Fishers can form collectives that provide grocers with sustainable catch. In return, grocers can strike deals with the fisher collective to guarantee to sell their product, allowing small-scale fishers to compete with large industrial fishing. I'm pretty sure arrangements like this exist, but I need to dig up the examples!
Great post Jared! This reminds me of a communal savings/loan program in Mexico called Patrimonia Hoy (link: http://www.cemex.com/SustainableDevelopment/HighImpactSocialPrograms.aspx). The program helps low-income families in Mexico create communal savings pools that go towards helping them build homes. Approx. 1/2 of new homes in Mexico are self-built, and construction materials account for most of a family's savings. The Patrimonia Hoy program was started by CEMEX, a large cement manufacturer, as a way to help existing low-income customers and access a larger customer base. The communal savings program helped cut down on construction costs and time for participating families. It's a great example of how large corporations that cater to mixed-income populations can leverage their resources in a way that benefits both them and their customers.
