Final answer:
The provided text discusses barriers to entry for businesses, not directly what a business incubator does. A business incubator helps new businesses grow, and does not provide an established brand name and advertising.
Step-by-step explanation:
The question is exploring the concept of a business incubator, which helps startups and new ventures to get off the ground by providing support services and resources. However, the information provided relates to barriers to entry in businesses rather than directly addressing what a business incubator does. The examples given, such as a patented invention, a restaurant recipe, an industry with small economies of scale, a price-slashing reputation, and a well-respected brand name, illustrate different ways that companies can create barriers to entry to protect their market position and inhibit competition.
A business incubator itself does not necessarily provide an established name and advertising; it's more about nurturing new businesses through their formative years with a range of supports such as office space, mentoring, networking opportunities, and sometimes capital investment.
