Industries that are viewed as specialty (instead of a commodity) have a high level of rivalry?
nikdorinn [45]

Answer:

Specialty goods are the products which require high efforts in purchasing because their cost is certainly high, consumers cant take a risk of buying them frequently, like sporting cars, high end cameras, luxury high end clothing etc. There are many industries in specialty goods in which you can see intense level of rivalry. For example, in sporting cars, you have multiple brands which have very severe kind of rivalry like Jaguar and BMW - Lexus and Lotus, they not compete in cars but they compete in their advertisements, evenest as well.

Whereas, when you consider, photographic camera industry, you will also find intense kind of rivalry between Canon and Sony, Leica and Olympus. Here they not only face direct competition from other camera brands, but they also have to face competition from the cell phone industry, which also provide high end cameras in their cell phones like iPhone, Samsung and Oppo etc.

Dima020 [189]

Answer:

Gunst should produce 500 Bio-mutant games:

                                   Android          Bio-mutant          Cyclops

selling price                  $100                 $107                   $125

  • total revenue = $107 x 500 = $53,500
  • total contribution margin = $71 x 500 = $35,500

If it produces 250 Android games its total contribution margin will = $9,000

If it produces 200 Cyclops games its total contribution margin will = $8,000
