what is demand curve
demand carve is a graphical representation of the relationship between the price of the or the service and the quantity demanded for a given period of time
Is the graphical representation of demand schedule. Also it has negative slope
The law of equilibrium is state that the quantity demand are equal to quantity supply.
sometimes demand exceeds supply or vice versa .In the first situation prices tend to rise therefore supply and demand meet the balance point called as equilibrium .
the point of intersection mathematically but this is just an assumption that all other variables remain equal
when there is excess supply and demand it means there is forces acting upon the equilibrium and prices should be decreased or increased appropriately
The law of equilibrium states that ceteris paribus, at a certain two variables will be equal to each other.
scarcity is the wants and desire of people of goods and services with limited resources and purchasing power to get it all

Cyclical unemployment .it has to do with an increase in the quantity of good demanded or there is over production which result in fall in prices. Industries will be affected it will now causes retrenchment of workers in the industries while structural unemployment arises as a result of slight change

Will now be retrenched as a result of economic recession... That is the little i knw....

Pls @Nibedita am confused
The state of balance achieved by an end user of products that refers to the amount of goods and services they can purchase given their present level of income and the current level of prices. Consumer equilibrium allows a consumer to obtain the most satisfaction possible from their income.
where is the calculations?

Basic Economic problems
what is the Basic Economic problem
what is the Basic Economic problem
Thembelani Reply
a bit of explanation please its my first year doing Economics
rare, limited. economic agents eg You dube, the govt & the business entities wants to maximise their utility/satisfaction but because limited resource or scarcity of such resources they are unable to satisfy their needs.
thank u Sir , l understand what you are saying now
limited resources; you wanna take the most benefits from the minimum resource.
if u ar a fresher, eco has to 2 fundamental parts "micro & macro". micro(small) this is were the economc agents ar discussd, economc systms, dmand & supply, typs of market systms etc and the macro (big) part the elucidates the functns of central bank, typs of employmnt, functns of money & int trade.
there is an old adage that says "a picture is worth a thousand words" economics is full of graphing so it requires on the side of the student to master the art of keeping information in form graphs.
oky Sir
scarcity becomes the fundamental problem of economics because of limited resources, when we take an individual, he or she has many wants, thus unlimited wants but can never satisfy all but only few.
now when we take a firm, a firm maybe willing to produce two or more product into the market but due to limited resources they only produce one. the same way if we take the government, he or she maybe willing to bring development either through infrastructures,
that is when consumer decision making rule comes in
choice arises as a result of scarcity of resources
so if we look through, the individual, firm and government, their wants are unlimited but due limited resources, all of their wants cannot be satisfy. therefore scarcity can be term as limited in supply of resources. scarcity is not lack of resources but insufficient resources
there is a marriage with the following; scarcity, factors of production, opportunity cost curve (occ) or (ppc, ppf, tc) production possibility curve productn possibility frontier transformation curve. The OCC, PPC, PPF & TC explains the decisions made by householders, firms & the govt.
opportunity cost also arises as a result of firm willing to produce a particular commodity but resources use in satisfying or producing such output is limited
wat ar those decisions? the most important is WHY nations economise tht is if they hav abundancy of factors of productn eg land, labour & entreprise? now since all of us have unlimited needs against few resourcs PPC, PPF, TC, OCC walks in to make wise allocatn of resources.
how do those decisions made? eg by economic agents; a. Household (You) - if u have R10 & wish to buy a book & a pen & realise that both commodities seĺl at the same price which of the two (2) can u buy (necesity) and which one can u forgo (not all tht important).
b. firms - they allocat mo resourcs to all thoz commoditz tht they think will yield mo profit. c. Govt - if the govt SA was to come in yo area which 1 would u think they can consider first tht can benefit the majority & the minority. So instead of building football stadium they construct a hospital.
if the SA govt had enough resources they would have built both the stadium and the hospital but because of scarce in terms of resources they had to forgo the construction the stadium to build a hospital which is necessary for the majority to benefit.
Opportunity cost well broken down..
opportunity cost means the lose of other alternatives when the alternative is chosen
saad Reply
is the benefits that you loose by not selecting a certain alternative.
individual wants maybe unlimited, but means to satisfy them are limited there one has to forgo some alternative in order to acquire other alternative and it must according priority, that is when scale of preference set in for individuals to make choice
hello everyone
Next best alternative forgiven
demand is the amount of goods and services that consumer is willing and able to purchase at a particular prices over given period of time
