Although known for sunshine, shopping, golf and its Old West history, Scottsdale's reputation is rising as a world-class center for innovative businesses, including many hi-tech, renewable energy and healthcare leaders. Local employers cite three main reasons for setting up business in the city - a quality talent pool, low operating costs and accessibility. Companies specializing in software, solar energy, radiology and a luxury car brand moved here to tap into the highly educated, motivated workforce. Arizona State University chose the city for the location of its W P Carey School of Business. Major freeway corridors, airports and good distribution are other draws for business. The business center is close to Sky Harbor International Airport near Loop 101, and Scottsdale is also home to a private jet airport.
