VMLY&R claims its BrandAsset® Valuator (BAV) Database is the largest brand database in the world. They are happy to partner with academic researchers. Their data pull is estimated to cost you $2,000–4,000. Students can ask for a fee waiver; for example, they can provide Brand Equity data and Brand Imagery Data for one year at no cost! Be prepared to sign an NDA and a Scope of Work if your request is approved. The output is in Excel format. The entire process can take up to 2-3 months, so fill up the short request form early.
