Market structure and product diversity

The diversity of the product on the market is closely related to its structure. Of

the definition of the two extreme types of market structures - monopoly and perfect competition, it follows that the monopoly company and firms in perfect competition offer a homogeneous product on the market that does not need advertising.

In monopolistic competition, sellers in the same market often provide a variety of similar products. Sometimes the diversity generated by manufacturers wasting resources for the production of many virtually identical brands of products is irrationally great. Since ensuring diversity leads to unjustified costs, society should make the choice of producing only some of the vast quantities of goods and services. The limitation of the number of items of goods produced in most markets is offset by the economies of scale, that is, the production of a larger volume of each type of goods at low unit costs. If more products are produced by fewer firms, then prices and unit costs become lower.

The effectiveness of diversity also depends on the level of socio-economic development of the state in which the market is localized. As the economy develops and the wealth of people grows, increasing diversity becomes more effective as consumer demand for diverse goods increases. In a very poor country, only one firm produces enough to meet demand.
As the economy grows and consumer demand expands, opportunities for an influx of more firms open up and market structures evolve toward monopolistic competition, providing consumers with the benefits of diversity.

Gains from diversity can be gained by taking advantage of international trade. Most trading operations between industrialized countries are carried out within the same industry. This trade in the field of differentiated products provides people of the interacting countries with access to a wider range of products, each of which is produced for the world

market, therefore, can be produced on a reasonably large scale.

With an oligopoly, several large firms dominate the market (from about three to five). Oligopoly exists because it is difficult for competing firms to enter this market, since the cost of entering the market is high (in the automotive industry, the amount of capital needed for this comes to billions of dollars). For example, until the early 1960s. american auto industry

was an example of oligopoly. However, as companies from Japan, Germany, South Korea and some other countries came to the American automobile market, the structure of the automobile industry was transformed into monopolistic competition.

Market structure and product diversity

  1. Non-price competition and product diversity in healthcare
    The manifestation of non-price competition and the desire of manufacturers to differentiate the product takes place in all, without exception, sub-sectors of healthcare. In the conditions of fierce competition, the medical industry enterprises apply the following methods of non-price competition:? providing volume discounts for the purchase of a large batch of equipment; ? deferred payment

A legal act is issued by a state body, an official within their competence in the form prescribed by law (law, decree, regulation, etc.). Blank Paper sheet, usually A4 or less,
  4. The diversity of the life cycles of RNA genomic viruses
    The type of RNA of the virus genome determines to a large extent whether translation, transcription or replication of RNA is the first step in macromolecular synthesis. Viruses with a (+) RNA genome (except for retroviruses) deliver genomic sequences directly to cell ribosomes and begin the infection cycle with the translation process (Figs. 7 and 8). Accordingly, these genomic RNAs
    The main trends characterizing the type of modern family that has dominated Europe and the USA since the mid-1960s are associated with changes in the value system, primarily, with the growth of individualism and rationalism. This is manifested in a decrease in the number of marriages, the spread of cohabitation (cohabitation unions), a drop in the birth rate and its “aging”, the predominance of small families,
  6. Principles of reforming the financing of the production of medical services in a market environment
    Since the end of the 80s, attempts have been made in our country to reform the domestic health care system. The main object of innovation is the system of financing medical care. In 1988-1990, the so-called new management mechanism was introduced in a number of regions, which changed the procedure for financing state medical institutions and their

    Each country should count, first of all, on its own natural, labor and intellectual potential R. Nigmatullin Everyone who is not indifferent to the decline in the prestige and degradation of domestic medicine should think about it.

  9. The phenomenon of collective knowledge: coordination of individual cognitive structures or the formation of supra-individual psychological structure?
    S. L. Rubinstein is one of the first psychologists who formulated the most important methodological position on the social nature of the psyche, concerning not only the phylogenetic aspect, but also the sociality of the ontogenetic origin of psychological phenomena. For the first time these ideas were formulated by him in his work “The principle of creative initiative” (Rubinstein, 1997). They formed the basis in principle

  11. . Virion structure
    The structure of viruses is the most advanced section of fundamental virology. A breakthrough in this area was facilitated by the idea of ​​the classics of biology, Watson and Crick (J. Watson and F. Crick) that simple viruses should be constructed from identical subunits and form structures having a spiral, cubic, or mixed type of symmetry (Table 1). 1, Fig. 2 and 3).
  12. Healthcare structure
    Under the sectoral structure of health care is understood the separation of the health care industry into independent parts, characterized by the specifics of the types of activities or services provided by the sub-sector. Due to the significant diversity of activities and health services and the lack of a single attribute, according to which such services can be divided into groups of homogeneous
  13. Food selection
    Assessing the nutritional health, we are not talking about a particular amount of essential amino acids, fats, carbohydrates, and not least, we are taking care of filling the body's needs in the natural composition of mineral salts. Moreover, we believe that vegetables are the main suppliers of not only these salts, but also vitamins. Regular consumption of vegetables and especially freshly prepared vegetables
