Hello

Hello

[Music]

Saint friends, smart greetings with your feet, the

advanced.ai economics tutorial in

this video we will learn together

about the perfect competition market, are

you ready, hi

kya

[Music]

friends, the essence of a perfect competition market

or often abbreviated as PTS

has several

characteristics, yes, so the first characteristic

is

Hi, there are many sellers and buyers

Hi,

so this first characteristic is the

difference between a perfect competition market and

other types of markets, yes, the first is that many are

sold and many buyers, well, the

first characteristic will have

an impact on

hi hi

Hi over businesses or producers as

prestek Hi,

so because there are many sellers or many

producers, automatically one producer

cannot control the price so

they cannot set the price

according to their own wishes,

therefore producers in a

perfect competition market act as

price takers or

price takers using prices that have been

agreed upon in the closed market, the meaning of

price taker, yes, the third

is that the goods traded

in a perfect competition market

are homogeneous or the same, there is no

difference, for example, like

rice, yes, rice. Maybe some come

from Cianjur, from Karawang or from

other areas, but they are also

sold in kilos and mixed,

we can no longer distinguish which

rice comes from Cianjur Karawang

or others

are called homogeneous goods Yes, it is different

from rice sold in supermarkets

that have labels or brands, namely it is

no longer included in the phase, it is no longer

included in the type of homogeneous goods

because they have differentiated

products, the

fourth is no barrier queue,

no barrier entry

Hi, the meaning of no barrier entry is that there is no

Hi,

Hi, entering the market, yes,

so producers want to enter or join the

PPS or want to leave, there are no

obstacles, such as no

obstacles to control of raw materials

or certain permits and others,

so they are free to join the

PPS or leave the PPS,

these four are the general characteristics or characteristics

of the PPS. Actually, there is

one more characteristic that is often

mentioned by several experts,

including information

Hi, perfect information, yes, Hi,

who, information about the

product owned by the buyer and

seller,

hi, hi,

Hi, so buyers know all the

ins and outs of the goods or products

traded in the market, yes, so they know

how many models the seller knows, how much the

original price is before the price offered

by the producer or seller is

perfect information, yes, after we

discuss the characteristics, we

will discuss the advantages, yes,

the advantages or benefits of a

perfect competition market, there are the

first advantages because there are

many articles of perfect competition sellers and many buyers

as a result consumers have

hi hi

Hi

many

choices Ah many choices in terms of

sellers because there are many sellers

so that if it is not suitable to buy from

one producer, you can buy from

another yes then the second is

surplus

Hi or profit yes Hi

consumers

Hi and producers

Hi that

Hi maximum

Hi this is a lot of choices from the producer

yes or the seller well the

second advantage is surplus or profit of

consumers and producers this is maximum so

producers do not take

too much profit from purchases or

goods sold by producers besides

that consumers also get benefits

in the form of prices received by them it

is a market agreement so

there is no excess sruputs owned by

consumers or producers so all of

this is maximum consumers get maximum

satisfaction producers also

get maximum satisfaction in the form of

surplus if this consumer is called

consumer surplus if this producer is

called producer surplus this is an

advantage yes next is the

disadvantage or weakness

yes so the disadvantage of the perfect competition market

is the first Hi Innovation and

research are low

Hi Innovation and research are low why is

that because in the long term the

price received by the producer

is what is agreed in the market so there is a

lot of normal aka zero profit if sis

zero means there is no remainder

used for research and

product development as a result innovation is low

and the specifications carried out are also

low intensity Yes

well after Innovation and research are

low the second drawback is the

profit that

Hai is obtained

Hai normal

Hai plus normal we can call

it a lot of zeros So it's not positive not

getting profit but he also doesn't

lose that yes So there is no spare

income or income from producers

that can be used to conduct

research or innovation Well next

after we discuss the advantages

disadvantages and characteristics or characteristics

we will discuss about balance

yes so balance is

hi hi Hi pskq balance of PPS

Hi Mbak balance of PPS

Hi that is Mr = MC

for all types of markets yes not only

PPS both monopoly later monopoly

or Oligopoly is the same Mr = MC but

the problem that distinguishes PPS from

other markets yes is

MP3 = Mr

Hai and = ar

Hai and = D

because p = mr automatically we can

replace or replace it to P =

MC this is the balance in the

perfect competition market yes so we can

replace Mr P to P = MC it is used

to find the price and amount of

equilibrium that occurs or is

agreed upon in the PPS of the perfect competition market

Hi

letter at-tin in the perfect competition market

can be described on the curve

So Yes so there are two curves - curves

for companies and curves for

industries or markets where the industry

is a combination of many

companies or producer yes Ah for the

company curve yes here

quantity and here price

well this is the curve in mania

demand curve = Mr = Ar = P Why is it

horizontal because it is a price

taker So the price remains the same even though the

company sells goods in

large or small quantities the price

traded remains at the point

agreed upon in the market yes that's the reason

why the curve is horizontal

or straight then this is the MJ curve which

is the Marginal cost curve

of the company so

this point is the equilibrium point

Hi BPS scales for a company

then it is different from the curve for the market

where the market is a combination of

many companies well this form

is

q & p well the shape of the demand curve here

in mania is horizontal but if

for the market curve because the combination of

companies in mania is in the form of a

negative slide so it decreases yes from the top left to the

bottom right Why because

if in the market yes from each

company It reduces the production of a

good or service then what happens is

the price will increase and vice versa

when each company becomes a

group of companies or producers that

increase production then the price will

fall like that but if he is only an

individual or one company

they cannot influence the price in the

market like This is the shape of the demand curve ah

the slide is negative and this is the

supply curve or we can also call this the

MJ curve is the same because the supply curve

or the offer curve owned by the

perfect competition market is the

MJ curve that cuts abcd the

minimum point is the origin of the

PPS curve so Oh some books

call it the supply curve some

call the MC Curve the same

so this intersection

produces Ki bintang or you can also

call it Ki equilibrium Ki

balance What is Ki bintang or

Kyai librium this is the amount of goods

traded in the market and it is

in a state of equilibrium so we

bintang or kayak librium is CD

the amount demanded by consumers is

the same as the amount sold so there is

no remainder Di same sold in

Hai sold and bought by

consumers other than Ki bintang from

the intersection of the Demand and supply curves will

produce p Bintang or you Eden friends

can call it P equilibrium yes P

equilibrium is the price

agreed upon by sellers and buyers in a

perfect competition market

it is a depiction or illustration

of the curve for the company as well as the curve

for the market in the case of PPS

perfect competition market then the

company has equilibrium

Hi there are two kinds of equilibrium yes

long-term equilibrium

Hi and short-term equilibrium

Hi simple meaning is

Hi in the long term companies that are

members of PPS only

gets Normal profit or later zero

yes, it means Normal profit is neither profit

nor loss

Oh yes, Normal profit is what

companies that are members

of PPS get but for the short term there are

three possibilities for a company to have a

positive profit, aka get a profit, it

can also have a normal profit that

has a lot of zeros, it can also have a

negative profit or it is called a loss,

the explanation is that when a

company enters a market where

the message is still small, automatically the choice

of consumers is not much, then the

producer can get a

positive profit then because there are no

barriers to market entry in PPS automatically

because one producer has

the possibility of getting a

positive profit, many other producers are

interested in joining to sell the

same product, as a result they enter the market,

there are no barriers, this is entering the market, it is

easy to become a competitor, initially one

producer places a

positive label because more and more

other producers enter and join to

sell the same product, as a result, there are

more and more consumer choices,

more and more competitors, so positive profits may

go down and down to normal profits

and there is a possibility of getting a

negative profit or loss because there are more and

more competitors, so to win the hearts of

competitors to win the hearts of consumers,

these competitors must

lower prices so that the price is too

cheap they can lose because Rumi will

return to his original site because he feels he has

lost, they leave the market, Saga charity makes

a profit again selling the same product

So they Exit the market because it

has harmed them out of the market

finally little by little their competitors

start to disappear in the market back again only

maybe a few producers are left

many come back positive Coral there

are no competitors like that that is

the cycle of PPS that causes

when in the short term can get

positive Normal or negative profits but

in the long term they will only

get Normal profits or profits 03

profit and no loss here is

an illustration of the

short-term and long-term equilibrium that

companies get when they are members

of PPS

good friend San to better understand

PPS or perfect competition market

Let's discuss questions

related to PPS yes so If the

demand function is known yes qb = 800

0.5 P demand function then followed

by TFC yes total fixed cost

fixed costs are equal to Rp10,000 and TVC

is 4q plus500 then Find the price and

equilibrium quantity at PPS well

friend SN need to remember that to get the

price and equilibrium quantity at PPS you

have to remember the formula that is p = mc this

is the equilibrium at

WPS so to find p Bintang and Q

bintang or the price and

equilibrium quantity from P = MC this

so In simple terms, we have to

get the P function and the MJ function, yes.

Well, we can get the tea function from the

demand function and the demand function

qd = 800 0.5 phi, we rewrite qd =

800 mint 0.5 phi, so in order to get P =

we have to change the position to the left side, yes,

so 0.5 P is positive Because

here it is negative, yes, move the side so it is

positive, equal to 800 min-ki, no

need to give a sign, it doesn't matter, yes.

So P = to eliminate 0.5,

both sides must be divided by 0.5, yes, like

this, divided by no sentence, so 0.5 phi /

0.5, the result is p800 divided by 0.5,

the result is

1600 and the unit is available before the left,

there is actually one But usually the number

13 is written in one divided by 0.5, that's

2q, this is a function

Hi, now we have to get the

MJ function, which is the limit, you must

know, yes So MC is the derivative

of the total cost, the first derivative, so

we have to get the PC function first, the

total cost of PC is

obtained from TSC + te

vca, well, we can get this TSC from

here, yes, we Enter 10,000 then for

TVC, sorry Nia vc, so for TVC

because what is known here is AVC,

we have to change the form to total

variable cost. What needs to be remembered

is that

AVC is formed from TVC divided by

keep, so to get TVC,

AVC must be multiplied by Kiya, so

cross-time, we write pvc goes to

produce AVC,

so to get

TVC because it is known to be AVC, AVC

must be multiplied by kidik alis missing, yes.

So for TVC,

we can write 4q

plus 500

multiplied by Ki,

okay, that's it, my friend, drops, yes, in order to

do it, for example, what is

needed is pvc and what is known is only

AVC, we only need to divert AVC

with Ki because the formula for AVC is

formed from TVC divided by we

just multiply it, it's lost between AVC

multiplied by Ki, well,

Hi, next we operate from TJ,

written 10,000

plus this, yes, so 4 Kiddy times the

result is 4q squared 500,000 times

with Ki, the result is

500 Ki, yes. So this is the TC in we

have got the total cost function

to operate PPS, we only

need emc so TC must be lowered

lowered once yes so PC accent

to get MC

I10 lowered against Ki is finished yes

because it does not have the variable Ki In

left 4 squared + 500

q4q squared lowered against Ki so

2 times 26 plus Ki so 2 times 4

times Ki the result is 8

plus 500 in the derivative means

only 500 kynya is lost this is left

Ci Because 2 is reduced by one yes

Because after being lowered the power

must be reduced by one so we

get TC accent aka NC yes this or

MJ is 8C plus500 so from the

result we can disguise with

right between P and MC Okay

now P = MC the result p that we have

obtained is rewritten

1600 min 2 Q = m c-nya

8ki plus500

which are both akik we group

the ones that do not have c we group

too yes these are two now because minus and

he changed position this he became + Win 8

key + 2q 500 initially plus because he

changed position to minus at 1600 Min

500 the result is

1100 =

10i

ih the result Q =

1100 divided by 10 we cross out get

ki110 this is C

equilibrium

at TPS

Ki equilibrium or cibintarok or the

next equilibrium amount that we have not yet obtained

is the equilibrium price yes so the

equilibrium price

we can get from because we value

IP we refer to the function of this pen

function

Hi mint two

we enter what has been obtained

IP =

1600 mint two times

110

the result is

1600

win228 is

1380 this is the equilibrium price at

PPS or P the stars are the same ih from the

questions that we have discussed

it is known that qd

855 pt.fcc Rp10,000 and AVC is 4q

plus500 then the equilibrium amount will be produced

at PPS 110 and the

equilibrium price at PPS

Hi

good friends essence that's the discussion of the

material regarding the perfect competition market
