                      monopoly.
                      New firms, with relatively low output, will find it difficult to compete
                      because theirs average costs will be higher than the existing firms

             UNIONS HAVE MIXED REACTION TO NATIONAL MINIMUM WAGE
                                ANNOUNCEMENT.

                                                              President Jacob Zuma’s

                                                              professions such as farm
                                                              workers and domestic
         workers would however be exempted. Unions have mixed reaction to
         minimum wage announcement. Cosatu and Fedusa welcomed the policy,
         stating that it will help us reduce inequality and poverty. Income is very
         important for the working people. This will help stimulate the economy
         because more consumers will be able to spend more money on the
         economy. South African Federation of Trade Unions (Saftu), rejected it.

                                               [Source: Adapted: ECONOMY, 5 November 2017]

         2.3.1       Identify from the extract TWO groups of workers who are not
                     included in this minimum wage agreement.

                         Farm workers 

         2.3.2       Briefly describe the concept minimum wage.

                     A wage rate set, above the equilibrium wage rate, by the government,
                     below which no employer can pay their workers                           (2)

                     labour.

                      The demand for labour decreases while the supply increases.           (2)

          2.3.4      Why is the national minimum wage good for South Africa’s
                     economy?

                     Minimum wage is good for South Africa because it can:
                      Reduce the income inequalities and poverty 

                      Increase demand for goods and services because low income

 2.4     Distinguish between a perfect market and a monopoly with regard to
         prices, profit, quantity and cost.

         Prices
         The monopolist produces at higher prices than the perfect competitor 
         Profit:
         Under perfect competition, only normal profit will be made in the long
         term;  the monopolist, on the other hand, can make economic profit in
         both the short and long term 
         Quantity:
         The monopolist produces less than the perfect competitor. 
         Cost:
         The monopolist does not produce at the lowest possible cost due to a lack of
         competition, whilst the perfect competitor will always produce at the
         lowest possible cost due to competition.                            (4 x 2)     (8)

 2.5     How will new entrants in the perfect competitive market impact on the
         profit levels of existing businesses?

         New entrants in perfect markets will impact on profit levels of existing
         businesses in that:
          New firms enter the market when existing businesses make economic
           profits in order to benefit from the profits 
          This increases the market supply. 
          the increase in supply leads to lower price levels of goods and
           services. 
          This causes smaller/lower profit than previously. 
          Production increases, until some businesses cannot cover their average
           variable cost any more  causing the shut down and exit the
           market. 

 QUESTION 3

 3.1    3.1.1 List any TWO types of monopolies.

                    Artificial monopoly 
                    Natural monopoly                                                       (2)

        3.1.2   What will the effect be if a firm in a perfect market decides to
                increase the price of its product?

                Firm will make a loss, because all firms in the perfect market are price
                takers and cannot influence the market price.                              (2)

 3.2    Study the information below and answer the questions that follow.

                     THE DEMAND CURVE OF AN OLIGOPOLISTIC FIRM

        The demand curve of an oligopolistic firm was developed in 1939 by the
        American economists Paul Sweezy.

        The kinked demand curve illustrates the importance of interdependence and
        uncertainty in an oligopolistic market and explains why there is a degree of
        price stability in such a market.

        Each firm will face a market demand curve with two segments for its product.
        The two segments are elastic and inelastic.

        3.2.1   Who developed the theory on the demand curve of an
                oligopolistic firm?

                Paul Sweezy                                                                 (1)

        3.2.2   What is the demand curve of an oligopolist firm called?

                Kinked demand curve                                                         (1)

        3.2.3   Briefly explain an inelastic demand.

                Demand is not sensitive to a price change. 
                A change in price causes a small change in demand.              (1 x 2)    (2)

        3.2.4   Explain mutual dependence as a characteristic of oligopoly.

                    One seller’s action will influence the other sellers 
                    Each firm is aware of each other’s actions since the market is
                     dominated by a few firms, e.g. cars.                       (1 x 2)    (2)

                             JASCO GIVES UP ON CROSS FIRE ACQUISITION

         Jasco Electronics Holdings has terminated a
         planned acquisition of Cross Fire
         Management after the competition authorities
         ruled against the merger last month.
         The Competition Commission prohibited the
         proposed merger, saying it would likely
         “substantially prevent or lessen competition
         in the provision of active fire protection systems”, particularly in the Western
         Cape and Gauteng regions.

                                                          [Adapted from fin24, 3 August 2017]

         3.3.1   Which authority did not allow the merger of Jasco and Cross
                 Fire?

         3.3.2   What was the reason for the denial of the merger?

                 The merger will prevent or lessen competition in the provision of active
                 fire protection systems.                                                          (1)

        3.3.3   Explain any other two objectives of Competition Policy other than
                those in the extract.

                    To prevent monopolies and other powerful businesses from
                     abusing their power 
                    To stop firms from using restrictive practices like fixing prices,
                    dividing markets etc. 
                    Improve the efficiency in the market through legislation 
                    Protect the consumer against unfair prices and inferior products
                     for example through the Competition Act 
                     Do not accept ‘preventing mergers and acquisitions’ and
                     ‘promoting healthy competition’.                                 (2 x 2)    (4)

        3.3.4   In your opinion how will the economy benefit from fair
                competition?

                The economy will benefit because fair competition will:
                 Open up opportunities for more entrepreneurs to join in to
                   businesses 
                 Create more job opportunities 
                 Lead to higher standard of living 

 3.4    Distinguish between the short and long term/run.

        Short term/run
         The short run is the period of production where only the variable factors of
          production can change. 
         The time period is too short to enable the number of firms in the industry to
          change.                                                            (2 x 2)

        Long term/run
         The long run is the period of production where all factors can change. 
         The time is long enough for variable and fixed factors to change. 
         It allows enough time for new firms to enter the industry and/or existing
           firms to exit.                                                      (2 x 2)         (8)

                                MONOPOLISTIC COMPETITION

                         As long as consumers perceive the
                       products to be different, then they are
                      different. It does not matter whether the

4.5 Why will it not benefit a monopoly to increase its price excessively?

      Increasing the price excessively will not benefit a monopoly because:
       Although the monopoly decides on production levels and determine their
         own prices, demand does not influence the price. 
       The monopoly is however influenced by the limited budget of consumers
         as they decide how much they will spend on a particular product. 
       Even though the monopoly is the only supplier of the product consumers
         may decide not to buy the product. 
       In as much as there are no close substitutes consumers may still substitute
         the product of a monopolist  e.g. paraffin for electricity 
       Increasing the price too high will lead to lower revenue. 

 QUESTION 5: MICROECONOMICS

       Examine in detail the oligopoly under the following headings:
        o   Nature of the product         (6)
        o   Control over price           (6)
        o   Collusion                    (14)                          (26 marks)
       How can firms in an oligopoly increase their market share in the
        economy?                                                        (10 marks)

 INTRODUCTION

 An oligopoly is a market structure that has few large sellers that dominate the
 market. 
 (Accept any correct relevant introduction.)                                                     (2)

 BODY
 Nature of the product
  Products sold may be homogenous or differentiated. 
  If products are homogeneous it is called a homogeneous oligopoly – many
    industrial products are standardised for example steel products. 
  If products are differentiated it is a differentiated oligopoly  – these firms
    produce goods such as household appliances, electronics equipment, breakfast
    cereals.                                                                   (Max. 6)

 Control over price
  Producers have considerable control over the price of their products, although not
   as much as in a monopoly. 
  Oligopolies can frequently change their prices in order to increase their market
   share. 
  This can result in a price war.                                          (Max. 6)

 Collusion
  Collusion takes place when rival firms cooperate by raising prices and by
   restricting production in order to maximise their profits. 
 Cartel 
  When there is a formal agreement between firms to collude, it is called a
   cartel. 
  A cartel is a group of producers whose goal is to form a collective monopoly in
   order to fix prices and limit supply and competition. 
  In general, cartels are economically unstable because there is a great
   incentive for members not to stick to the agreement, to cheat by cutting
   prices, illegally and to sell more than the quotas set by the cartel. 
  Although there is an incentive to collude there is also an incentive to compete. 
  This has caused many cartels to be unsuccessful in the long term.  Some well-
   known cartels are the Organisation of Petroleum Exporting Countries (OPEC) and
   De Beers diamonds in South Africa. 

 Overt/formal collusion 
  Overt/Formal collusion e.g. cartels are generally forbidden by law in most
   countries 
  However, they continue to exist nationally and internationally. 

 Tacit collusion 
  Sometimes in an oligopoly market, a dominant firm will increase the price
     of a product in the hope that its rivals will see this as a signal to do the same 
  This is referred to as price leadership.                                     (Max. 14)   (26)

 ADDITIONAL PART

 How can firms in an oligopoly increase their market share in the economy?
 Oligopolies can increase their market share by using various strategies such as:
  Engaging in product differentiation, where the products are made to be slightly
     different in terms of physical appearance, packaging etc. 
  Improving after-sale-services that are far more important to customers and will
     ensure a long-term relationship with that business 
  Aggressive advertising to lure consumers onto their side 
  Establishing brand loyalty, because oligopolies want consumers to believe that
     its brand is the best and to buy only that brand 
  Engaging in product proliferation whereby oligopolies produce many different
     ranges of products to cater for many different markets 
  Extending shopping hours to encourage greater flexibility to households 
  Selling products online to make it easier for customers to shop around without
     any additional costs  and a variety of goods is made available to make
     comparisons. 
  Paying loyalty rewards to customers for continued support. 
     (Accept any other relevant, correct response.)                                           (10)

 CONCLUSION

 Oligopolies can control the supply of the product or service on the market, in order to
 keep its prices and profits high. 
 (Accept any other high order conclusion.)                                                     (2)
                                                                                              [40]

 QUESTION 6

     Discuss the following factors that lead to misallocation of resources in
      the market.
      o    Imperfect competition                             (8)
      o    Merit and demerit goods                           (10)
      o    Immobility of factors of production                (8)      (26 marks)
     With the aid of well-labelled graphs explain productive inefficiency as a
      consequence of market failure.                                   (10 marks)

 INTRODUCTION

 Market failure occurs when the forces of demand and supply fail to allocate
 resources efficiently. 
 (Accept any relevant introduction.)                                                      (2)

 BODY

 Imperfect competition
  Competition in market economies is limited by the power of certain producers to
   prevent new businesses from entering the market. This is imperfect
   competition. 
  Barriers to entry are created because of advertising, a lack of capital and the
   controlling of resources. 
  The imperfect market does not allow for price negotiations. 
  Advertising is used to promote producer sovereignty (dominance), which
   encourages consumers to buy existing products and allows producers to delay
   new products from entering the market until it is in their own interest  (e.g.
   businesses have had the technology to produce long-life light bulbs for many
   years but have chosen not to launch them in the market).                             (8)

 Merit and demerit goods
 Merit goods:
  These are highly desirable for general welfare, but not highly rated by the
   market, e.g. health care, education and safety. 
  If people had to pay the market price for them, very little would be
   consumed. 
  The market fails because the market produces less than the desired
   quantity. 
 Demerit goods:
  These are over-consumed goods,  e.g. cigarettes, alcohol and drugs. 
  Thus more of the goods are produced than is socially desirable. 
  The government bans or reduces consumption of these products through
   taxation, and provides information to the population on their harmful effects. 
                                                                           (Max. 10)

 Immobility of factors of production
  Labour takes time to move from one area to another. 
  The supply of skilled labour cannot be increased because of the time it takes to
   be trained or educated. 
  Physical capital, like factory buildings or infrastructure such as telephone lines
   cannot be reallocated easily. 
  Structural changes like a change from producing plastic packets to paper
   packets or shifting from labour-intensive production to computer based
   production requires a change in labourers’ skills, employment and work
   patterns. 
  This takes time to change.                                              (Max. 8)           (26)

  Productive inefficiency can be explained with the aid of the productive possibility
   curve. 
  The Production Possibility Curve (AA), above shows a combination of goods
   that can be produced using all the available resources. 
  Any point on the curve shows a combination of goods where resources will be
   used efficiently. 
  Therefore any point on the curve indicates Productive/Technical efficiency 
  Any point to the left of the curve such as D, indicates that some resources are
   unused. If this occurs some customers may be deprived of goods. 
  This depicts productive inefficiency.                                  (Max. 6)
 CONCLUSION

 When market failures occur, it causes inefficiency and misallocation of resources
 and the government will have to intervene to recover the instability. 
