VRAAG

5 Macro objectives


Economists usually distinguish five objectives of macroeconomic policy, which in its turn can also be used to appraise the performance of the economy. The macroeconomic objectives are: economic growth, full employment, price stability, income equality and balance of payment equilibrium.  

  • Economic growth is determined to establish a country's total production of goods and services. (GDP) 
  • Full employment - The unemployment rate is calculated to establish the level of unemployment in a country.
  • Price stability - Economists are interested in what is happening to the prices of goods and services. They want to know what is happening to inflation.  How do we calculate the inflation rate?
  • Income equality - Meaning, how is income distributed amongst individuals or households.  Income equality is measured by the Gini coefficient and the Lorenz curve.
  • Balance of payment - This concerns a country's economic links with other countries.  A country keeps record of its transactions, the amount of exports, imports, investment, savings and so on.

Kom ons gooi die owerheid in die inkomste en bestedingskringloop in


As ons kyk na die rol van huishoudings en firmas in die ekonomie (soos hierbo uitgebeeld) sal ons sien dat alle faktore van produksie deur huishoudings besit word. As jy daaraan dink maak dit sin want al die besitters van grond, kapitaal, arbeid en die fabrieksbase het tog almal huise waarheen hulle na werk terugkeer. Firmas aan die ander kant benodig hierdie produksiefaktore van huishoudings, terwyl huishoudings die produkte wat die firmas aanbied benodig. Daar is dus ’n onderlinge afhanklikheid en dit is die rede waarom daar faktormarkte en goederemarkte bestaan. Die een mark koop en verkoop faktore van produksie en die ander goedere en dienste. Let daarop dat die goedere – en dienstekringloop in een rigting beweeg en inkomste en besteding in die teenoorgestelde rigting.
Die owerheid/regering word in die kringloop by gegooi. Die regerings is die land se Fiskale Owerheid en sy vernaamste fiskale instrumente waarmee dit die ekonomie kan manipuleer is: Owerheidsbeteding (G) en belasting (T). Onthou owerheidsbesteding is 'n inspuiting in die ekonomie en belasting 'n lekkasie.

Maak seker dat u die ekonomiese kringloop kan teken en verduidelik.

Die onderlinge afhangklikheid tussen die belangrikste sektore, markte en vloeie in die gemengde ekonomie.


Volgende week in klas gaan ons bietjie kyk na die onderlinge verband tussen die belangrikste sektore, markte en vloeie in die ekonomie. Die vloei van produksiefaktore tussen privaat huishoudings, firmas, die owerheid, finansiële instellings, soos banke, en die buiteland word aangetoon, asook die vloei van vergoeding, geld en/of fondse tussen hierdie sektore.


 
Wanneer daar gekyk word na huishoudings en firmas in ’n ekonomie kan ons sê dat alle faktore van produksie word deur huishoudings besit, want die besitters van grond, kapitaal, arbeid en die fabrieksbase het tog almal huise waarheen hulle na werk terugkeer. Firmas benodig hierdie produksiefaktore van huishoudings, terwyl huishoudings die produkte wat die firmas aanbied benodig. Daar is dus ’n onderlinge afhanklikheid en dit is die rede waarom daar faktormarkte en goederemarkte bestaan. Die een mark koop en verkoop faktore van produksie en die ander goedere en dienste.

Production Possibility Curve



A Production WHAT??

Last week in class we looked at what is economics.

After looking at the definition of economics we saw: decisions, decisions, decisions, decisions - since recourses are limited (We can’t have everything or produce everything all the time). Therefore, if you are a producer of chocolates and soft drinks how many chocolate and soft drinks should you produce given your recourses? This is where the production possibility curve fits in.

A production possibility curve therefore:


• Represents a simple economy;

• only two products are produced;

• resources are limited;

• different combinations are available where one can produce

• producer needs to make a choice – where to produce.


Consider this example:

A producer can choose to produce either chocolate or soft drinks. His schedule of possible production combinations is given below:


Considering the possible production combinations the production possibility curve will look something like this:


If the producer decided to produce 500kg of chocolate, what is the opportunity cost for producing the 500kg of chocolate? (Therefore, how many litres of soft drink does the producer need to give up in order to produce the 500kg of chocolate?)


If the producer produce 500kg chocolate, he produces 600 litres of soft drink. If he produced just soft drinks he would have produced 1000 litres. The producer did not choose to produce 1000 litres, he decided to produce chocolate (500kg). The opportunity cost for the 500kg chocolate is therefore 400 litres of soft drinks (1000 litres – 600 litter).

Remember to watch the tutorial video under Video’s for step by step instructions on what is a production possibility curve and how we calculate opportunity costs.
