Permintaan dan Penawaran Dalam Ekonomi

Assalamualaikum, kita kembali ke bab 2 bab 2 adalah demand dan supply ok, pertama kita pergi ke definisi demand ok, apa maksudnya demand? demand adalah berbeza dengan kemampuan dan kemampuan untuk membeli kuantiti yang spesifik dalam masa yang diberikan pada harga tertentu, seterusnya ok, apabila anda mempunyai kemampuan atau kemampuan untuk membeli Okay, itu adalah demand Okay, what is mean by setteris peribus? Setteris peribus means all other things remains the same Maksudnya, other factors are not influencing the demand Okay, law of demand Okay, law of demand state that When the price is State that the higher the price of gold The lower is the cruelty demanded for that gold And the lower the price, the higher is the cruelty demanded Setteris peribus Okay, so law of demand state that Okay, law of demand state that when price increases, quantity demanded will decrease.

Or vice versa, when price decreases, quantity demanded will increase. Okay, maksudnya normal lah kan? So, we as original buyer normally we want to buy the product at a lower price.

If the products are more expensive, kita beli tak? Kita tak akan beli, betul tak? Kalau usually memang kita tak beli lah.

So kita akan prefer untuk barang yang murah, kuantiti demanded akan meningkat. Tapi sebaliknya kalau harga barang yang mahal, kita beli sedikit lah. So it shows a negative relationship between price and kuantiti demanded. Why negative?

Because when price increases, kuantiti demanded will decrease. When price decreases, kuantiti demanded will increase. Hubungannya selalu negatif lah.

Itu normal. Okay, demand curve. So how to draw demand curve?

So this is the demand schedule. Okay, it shows the... harga dan kuantiti. Lihat harga, pada RM 5 kuantiti diperlukan 2, pada RM 4 kuantiti 4, pada RM 3 kuantiti diperlukan 6. Jadi, ia menunjukkan bahawa apabila harga menurun 5, 4, 3, 2, 1, ia menunjukkan kuantiti diperlukan akan meningkatkan. Jadi, bagaimana untuk mencari kawasan permintaan?

Pertama, anda mencari garis vertikal dan horizontal dan di sini anda menampilkan sebagai kuantiti dan di sini ia menunjukkan harga. Baiklah, bagaimana untuk mencari, bagaimana untuk mencari? Lihatlah tabel ini.

5 ringgit, kota dimana itu 2. 5 ringgit, kota dimana itu 2. 5 ringgit, kota dimana itu 2. Lihatlah. 4 ringgit, kota dimana itu 4. 3 ringgit, kota dimana itu 6. 2 ringgit, kota dimana itu 8. And at RM1, kuota demand rate is 10. Okay. Then you combine all these points by using ruler lah eh. Dia tak ada ruler. So this is demand curve.

This is demand curve. Sellable as a D lah, demand curve. It shows a negative slope.

Dia mencurang ke bawah. Okay. Dia slope negative lah.

Because when price increases, kuota demand rate will decrease. So it shows a negative slope. Okay. Okay, this is the differences between individual demand and market demand.

Individual demand refer to the relationship between the quantity of food demanded by a single individual and its price. Okay, contohnya, Halim dia nak beli rambutan. Dia seorang je yang nak beli. Okay, dia seorang je beli rambutan. So, Halim tu refer to individual demand atau single individual lah.

Okay. Market demand derasisi between the total quantity of a good demanded by adding all the quantities demanded by all consumers in the market and its price. Kita tambah semua bilangan yang dibeli oleh semua consumer dalam pasaran. Contohnya, kita total up all the quantities demanded by all consumers. Contohnya, berapa banyak.

rambutan yang dibeli oleh rakyat Malaysia contohnya lah itu adalah market demand total up of the consumers the consumers lah demanded by all consumers so it depends on individual demand and market demand ok, given price and demanded by individual 1 and individual 2 so this is individual demand for individual 1 so this is individual demand for individual 2 so Okay, so kita just total up je lah. Okay, at RM5, how many market demand? So, 2 plus 4. So, market demand is 6. Okay, 6. At RM4, market demand is 9. At RM3, market demand is 12. At RM2, market demand is 8 plus 7, 15. And at RM1, market demand is... 18. So, this is the market demand.

Kita tulis up the individual demand lah. Okay. It is demanded by by all consumers.

Okay. So, this is how to plot market demand schedule for PEN yang dalam yang case-at-dini. Okay. So, tengok lah.

Okay. So, first you draw the vertical and horizontal line. Okay. Then, you plot, contohnya you buat scale 1, 2, 3, 4, 5, sebab dia punya scale senang mudah je, 1, 2, 3, 4, 5 6, 9, 12, 15, 8, 8 ok, so gunalah 6, 9, 12, 15, 8, 8 guna sekarang yang betul lah, ok so just plot the market demand, do not plot many in the global demand when there are many demand available, ok, so just plot the market demand, bukannya plot demand curve for level 1 in level 2 bukan just plot the market demand so at RM5, quantity is 6 at RM5, quantity is 6 RM5, quantity is 6 sini kan at RM4, quantity demanded is 9 9, RM4 9 saya tengok sini je lah RM3.12 at RM4 sorry RM2.15 and last RM1 is RM8 ok then you combat all this point by using ruler eh a ruler ok so this is dream on curve it's just a negative slope ok sama jugalah kalau you practice gunketa graph ok, how to plot demand curve so you draw the sorry, ok so you draw the vertical line ok, sekarang oh, tak sama ok and he label as a quantity and he is price so plot lah, buat scale berdasarkan pada table yang diberilah kalau sini dia punya skala senang je lah 1, 2, 3, 4 1, sorry 1, 2 3, 4 5, dan sini tadi dah kan?

6, 9, 12, 15, 18. Okay, and then plug macam biasa lah. Okay, ini kalau guna kertas kraft lah. Okay, okay, determinants of demand.

Okay, so there are two factors actually. Plus factor and non-plus factors. So, plus factor is part of the group itself. So, this will result in the investment along the demand curve. Okay, plus factor, how to explain?

Okay, plus factor ni disebutkan harga barang tu sendiri. Contohnya when the plus of chicken, plus of chicken, contohnya case chicken. Plus of chicken increases so quantity demanded of chicken will decrease. Atau when plus of chicken decreases, quantity demanded of chicken will increase.

Itu maksudnya plus of the good itself, harga barang tu sendiri. Okay? Bila harga chicken berubah, quantity demanded untuk chicken akan berubah juga. Kenapa kuantiti berubah?

Disebabkan oleh faktor harga. This will result in movement along the demand curve. Kenapa kuantiti berubah?

Disebabkan oleh faktor harga. Non-price factor. Factors beside price of the good itself.

Maksudnya selain daripada faktor harga. Example, consumer's income, taste and preference, expectation of future price, number of buyers, advertisement, price of the good, complementary and substitute. ini akan menyebabkan pindahan kurung jari.

ok apa maksudnya komplementari baik Kapun cerikut is good that must be used together. Okay. Barang yang perlu digunakan bersama-sama.

Example, car and tire. Apa lagi? Car and tire, handphone and bag. Charger.

Tak ada charger macam mana nak hidup. Atau power bank. Kan.

Barang yang perlu digunakan bersama-sama. Atau marker and ink. Substitute, barang yang menggantikan barangan.

Example, milo. Air milo. Air teh, air teh, air kopi kan. Air kopi mahal lah, belilah air orange. Orange mahal.

Belilah air sirap. Sirap mahal, minumlah air kosong. Air juga kan, dia menggantikan barang. Barang yang sama lah, barang yang satu lagi lah. Dia boleh menggantikan barang yang lain.

So, the demand result in the shifting of demand curves. Okay, nah, sebagaimana demand curve shift ni kita tengok nanti. Okay. So, this is the changes in quality demand rate and changes in demand. Okay.

So, changes in quantity demanded, it shows a movement along the demand curve. Okay, changes in quantity. Highlight sikit eh.

Quantity, maksudnya nak tengok pada perubahan pada quantity. Okay, quantity. Okay, it shows a movement along the demand curve. Okay, price changes and other factors are causing.

Maksudnya, kenapa berlaku dalam quantity disebabkan oleh faktor harga. Okay, when price increases, quantity demanded will decrease. Kau ngga eh? contohnya, ini adalah harga asal PONKO apabila harga meningkat ke P1, apa yang akan berlaku?

jumlah akan meningkat ke Q1 apabila harga meningkat, kontinu mandut akan meningkat jadi, ia menunjukkan pergerakan pengambilan pergerakan pengambilan, apabila harga daging sendiri meningkat akan meningkatkan kontinu mandut betul tak? apabila harga meningkat, kontinu mandut akan meningkat ia menunjukkan pergerakan pengambilan And when price When price decrease Example from PO to P2 Harga turun eh P2 So it shows What happen Okay this is the original PO Okay Then when price decreases From PO to P2 It shows Multi-demanded will increase Betul lah kan Law of demand When price decreases Multi-demanded will increase kan So bila harga jatuh Multi-demanded akan bertambah So it shows A downward movement So downward movement when the price of the goods itself decrease, there will be an increase in QTD. Bila harga barang turun, QTD akan bertambah, dia menunjukkan.

It shows a downward movement. So what are the factors that influencing the changes in QTD? Price itself. Factor dia adalah price. Price itself.

Harga barang tu sendiri. Kenapa dia bergerak ke atas ke bawah? Faktor dia adalah price itself.

Okay. So for changes in demand, saya rasa saya akan pergi ke next video. Sebab video ni just limiting 15 minutes.

Okay. Proceed next video. Okay.
