This involves the highest degree of the imperfection and, therefore, the greatest control over the market. It is a market situation characterized by: A large number of buyers A single seller A commodity which has no close substitutes Restrictions on entry Monopolistic competition This market situation is a bit closer to real life. It is characterized by: A large number of buyers A large number of sellers Selling differential products Free entry and exit Example: cereal, toothpaste, cigarettes, detergents, etc. Contoh: DAIA (PAKAI DAIA LUPAKAN YANG LAIN) Sabun kecantikan dan sabun kesehatan=sama2 sabun, Cuma set mind orang ini untk kecantikan, ini utk kesehatan.. Ada juga yang namanya persaingan penjual klo menjual satu product. CARI TAHU TENTANG UNILEVER MILLY.. OLIGOPOLY It is also a real life case, especially in the are of large-scale industries. It is characterized by: A large number of buyers A few sellers Either homogeneous or differential products Two sellers duopoly Pure oligopoly product homogeneous Differentiated oligopoly, difference product Not easy to entry Itu tetep di business ethic..

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
