Kinked Demand Curve Analysis

Critically analyze the proposition that the comparative stableness of monetary values in an oligopolistic market is adequately explained by the Kinked-demand curve analysis. What other theories have been developed to explicate this phenomenon?

Introduction – 150

Oligopolistic Market – 400

It can be argued that the most of important theories of the house is the theory of oligopoly. There are few industries within the European Union and the United States of America that are amiss and monopolistically competitory consisting of many houses. However, the bulk of bing industries are oligopolistic where really few houses operate portion a big proportion of the industry ( Anderton 2001 ).

Features of houses in the industry are:

  • Significant barriers to entry curtailing the entryway of new houses into the market. These barriers differ from industry to industry and are similar to those under monopoly.
  • Interdependence between houses. Firms are reciprocally dependent due to the fact that each house will hold to take history of others as a consequence of really few houses runing in the industry. The gross revenues of a rival house will be affected by the determination a house to change specifications or monetary values of a merchandise. Monetary values and specifications may be changed as a response by challengers. Therefore, each house is affected by the actions of challengers ( Sloman and Sutcliffe 2004 ).
  • Few houses must find the supply within the industry. An illustration would be an industry where four houses produce 85 per cent of end product even though the industry may dwell of 96 smaller houses. This type of industry would still be classified as oligopolistic. Even though there are important characteristics that distinguish oligopoly from other market constructions, differences still exist between houses. Even though houses may be bring forthing virtually homogeneous goods, these merchandises are still differentiated as is the instance with autos and soap pulverizations. Much of the competition between oligopolies relies on elements of a selling mix instead than entirely concentrating on monetary value summarised as the ‘4 Ps ‘ ( Anderton 2001 ).

The ‘4 Ps ‘ refer to:

  • Products a houses produces which entreaties to clients,
  • Price a houses will put depending on the pricing scheme implemented by the house,
  • Promotion such as advertisement making consciousness to purchasers of goods presently on sale and,
  • The Place the good will be distributed doing it easy entree for clients.

To cut down the uncertainness of net incomes houses may ensue to collusion enabling them to maximize net incomes. Formal understandings between houses affecting collusion are known as trusts. Large punishments are dished out in many European and US industries due to the formation of trusts being outlawed.

Kinked Demand Curve

A Kinked Demand Curve theory was developed in 1939 of non-collusive oligopoly. This theory is used to explicate monetary value stableness in an oligopolistic market. The theoretical account developed by Paul Sweezy, R.L. Hall and C.J. Hitch seeks to explicate how monetary values remain stable even when there is no collusion between oligopolies.

An premise of the Kinked Demand Curve theory is that an oligopolistic house will confront two demand curves as a consequence of a crick. The point of the crick is the constituted market monetary value within the industry. The demand curve comprises of two sections as a consequence of this crick. The first section relates to the addition in monetary value by a house ensuing in the demand curve being comparatively more elastic, whereas, the 2nd section relates to a house diminishing its monetary value ensuing in a less elastic curve ( Webmaster 2009 ) .

The theory assumes a alteration in monetary value by one house will take to two asymmetrical reactions. The first being when house A reduces its monetary value, other houses in the industry will either maintain or cut its monetary values due to a fright of losing clients or gross revenues to the first house.The house ‘s docket to diminish monetary value can be farther represented by Figure 1.2. At the industry monetary value Pe, a lessening to monetary value P2 will take to an end product from Qe to Q2 along the inelastic AR=D curve. This will go forth the house doing a loss in Entire Revenue ( TR ). The protagonism in monetary value stableness is due to the shaded bluish country stand foring a loss in TR being greater than the shaded gray country stand foring a addition in TR. This is chiefly down to the inelastic demand curve AR=D, where a per centum alteration in monetary value leads to a comparatively smaller antiphonal alteration in measure demanded.

The 2nd being when an oligopolistic house raises its monetary value, its rivals will non be induced to follow suit, go forthing them to derive market portion. The house ‘s docket to increase monetary value can be farther represented by Figure 1.3 below. At the industry monetary value Pe, an addition to monetary value P1 will ensue in an end product for the house from Qe to Q1 along the elastic AR=D demand curve. Due to the shaded bluish country stand foring a loss in TR being greater than the gray country stand foring a addition in TR, the house will be merchandising at a loss. This once more encourages monetary value stableness for goods in an oligopolistic market. This TR loss is down to a comparatively elastic demand curve AR=D, where a per centum alteration in monetary value leads to a greater antiphonal alteration in measure demanded. The stableness in monetary value in an oligopoly market leads to houses seeking to obtain a greater portion of the market via non-price competition.

Conclusion – 150

Even though it is clear the Kinked Demand Curve points out at that place will be monetary value stableness in an oligopolistic market, there is no reference of other factors that may fluctuate monetary values. The Kinked Demand Curve theory does non give any indicant as to the grounds why monetary values are set.

Factors included in the ‘4 Ps ‘ are really influential in an oligopolistic market. Oligopolists will be more inclined to pour supranormal net incomes into the research and development section than that belonging to a monopoly. This will be to help the value of a merchandise by increasing design, bettering efficiency or by technological betterments.

The topographic point of the merchandise can besides hold an impact on monetary value. An air hose company may hold alone entree to a geographical location of a state enabling the house to run about as if they were a monopoly. Making the merchandise handily available for consumers will give the house strategic advantages that will non be easy copied by rivals ( Daniels, Radebaugh & A ; Sullivan 2001 ).

Anderton ( 2001 ) advocates the demand for the Kinked Demand Curve to aknowledge other factors than monetary value. The chief premise of the theory is that houses will ever respond to other rivals alterations in monetary value but in world the this is non the instance.
