Representation of Supply

Monday, August 24th, 2009

 

suppThe Supply curve is represented going upwards as price increases. As the price consumers are willing  to pay for any goods or service increase, the quantity producers are willing to supply increases. The incentive for the suppliers are selling more goods at higher prices(therefore increasing profit). In this example the suppliers are willing to supply 200 quantity of x for the price of $20, but as the price increase there is a greater interest and therefore they are willing to supply 300 units of x for $25  ; 400 units of X for $ 50 and 500 units of x for $100.

Production possibility curve. (PPC)

 

 

The production possibility curve is a model used to show the output possibilities of an economy.

While a real economy produces hundreds of thousands of goods and services we use this simplified model to show the relationship in the opportunity cost of things and also demonstrate the capacity of the economy.

 

In the diagram we have production possibility curve for 2 products DVD players and microwave ovens.

 

 

The blue line represents all combinations of both products that could be produces simultaneously in an economy.

 

(Insert diagram here)

 

 

 

At point A in the diagram you could produce 2000 microwave ovens and 700 DVD players. The opportunity cost of producing the 2000 microwave ovens are the 300 more DVD players that could be produced if not for diverting resources for the production of the microwave ovens. The same could be said for 1000 more microwave ovens that could be produced if not for the production of 700 DVD players. In economics we call this the opportunity cost. (Hyper link to all pages with this word)

 

At point B we see that 1000 microwaves could be produced while producing 300 DVD players. At this point we see that there is opportunity to produce more of both products since we are well within the PPC we call this under production.

 

If we wanted to produce the combinations of both products at point D it is not possible with the resources available or utilized at the moment. This however is probable not be  a permanent situation. Better technology , more land, labour  and capital could result in the production possibility curve expanding on both horizons that far exceeds current production capacity. In economics we call this positive economic growth.

Macroeconomics and microeconomics.

The study of economics is divided into 2 main parts Macroeconomics and Microeconomics.
Macroeconomics is dealing with the economy as a whole taking into consideration the whole economies Gross Domestic Product, inflation rates and Interest rates. In this we deal with the study of the economy as a whole and its trends and current and future predictions. E.g. Australian GDP in the years 2005 – 2006 had a positive growing while increases in inflation rates were low while interest rates kept going up.

 Microeconomics deals with specific sectors and industries in an economy. In this field we look at growth rates and changes that take place within this industry over time, its current trends and future growth. E.g. In Australia in the year 2005- 2006 because of sustained growth and rising wages in the labour market there was a lot of pressure building up in the housing and real estate industry. This resulted in a rise in prises of real estate specially in metropolitan areas and suburbs. Because of the sustained economic growth the Federal Reserve of Australia raised interest rates, this drove down the pressure in this industry as less people could now afford to take out loans to buy housing. After a while (i.e. a few months) the demand for real estate kept rising again till the government hiked the interest rates yet again.

Evolution

Tuesday, May 6th, 2008

Man has unlimited wants which has to be satisfied with limited resources. Over the centuries man has tried to find an answer to this problem. Three distinct different approaches to manage this resource have been attempted.

Traditional - In the traditional approach to managing the economy is giving the highest priority to farming and agriculture. Farming was given the highest importance since that was the biggest employer in the economy. The jobs in this system of economy is passed down from one generation to the next (e.g. a farmers son would be a farmer).There was not much thought given to improving the efficiency or technology of farming in any formal way.

Command – This system of economy functions by the direction of a single central command. Usually this could be a leader (e.g. King , Draconian Dictator, a central council – communist council). The central command decides which industries in an economy are important and the wage rates and allocates number of people for each task in the economy. Interest rates and property ownership and taxation are decided by the central authority. It is characteristic to have extensive research and development centres to improve efficiency and reliability.

Market – In the market system of economics the importance to various sectors of economy are given priority to this potential in giving back profits, thus most profitable industry is given the highest priority. The wage rates, Interest rates are determined by market forces (i.e. Supply and demand). Individuals are free to choose their occupation. Research and development to improve technology is done by private sector.

There is also another hybrid system. Most countries have a similar system of economic management to this.

Mixed system – In the mixed system the priority to industries are set mainly using the market system but are also protected and a social importance is given to certain sectors even though it might not be very profitable. Interest rates and wages are open to market forces but there are certain minimum levels of wages already set and maximum interest rates that are set too.
