We call the point where those two curves meet the equilibrium. The point where supply and demand are in agreement is the equilibrium. That is the point at which suppliers are willing to sell roses at the same price consumers are willing to pay for them. So with 600 roses, 600 boxes of roses or whatever it is the equilibrium price is $3. Well, it's a rose, So with 600 rose the equilibrium rice is $3. That is, both parties are happy in equilibrium.
The key point about equilibrium, as the name implies, as the term equilibrium implies, It's the point where the system has come to rest.. Where both parties are happy with the outcome.
Both parties are happy because it's on the demand and supply curve. Since it's on the demand curve, consumers are willing to pay $3 for 600 roses. They wouldn't pay $4 for 600 roses, but they'd pay $3.
Since it's on the supply curve, suppliers are willing to accept $3 for 600 roses. They wouldn't accept $2 for 600 roses, but they'll accept $3 because it's on the curve. So basically, it's just two equations and two unknowns. You set these two things equal to each other and you solve, and you get q star equals q star equals 600. And p star equals 3, just by two equations and two unknowns. Once again, why we only have two goods. I could have done this in three dimensions. The graph would have been uglier. The math would have been harder, but nothing would have changed.
Inti dari keseimbangan, seperti yang tersirat dari namanya, atau dari istilah equilibrium, adalah titik di mana sistem telah berada dalam keadaan tetap, di mana kedua pihak puas dengan hasilnya. Kedua pihak puas karena titik itu berada pada kurva permintaan dan penawaran. Karena titik itu berada di kurva permintaan, konsumen bersedia membayar 3 dolar untuk 600 mawar. Mereka tidak akan membayar 4 dolar untuk 600 mawar, tapi mereka akan membayar 3 dolar.
Karena titik itu berada di kurva penawaran, pemasok bersedia menerima 3 dolar untuk 600 mawar. Mereka tidak akan menerima 2 dolar untuk 600 mawar, tapi mereka akan menerima 3 dolar karena titiknya berada pada kurva. Jadi pada dasarnya, ini hanya dua persamaan dengan dua variabel. Kamu menyamakan kedua hal itu dan menyelesaikannya, dan kamu mendapatkan q-bintang sama dengan 600, dan p-bintang sama dengan 3, hanya dengan dua persamaan dan dua variabel. Sekali lagi, alasan mengapa kita hanya menggunakan dua barang: saya bisa saja membuatnya dalam tiga dimensi. Grafiknya akan lebih jelek, perhitungannya akan lebih sulit, tetapi tidak akan ada yang berubah.
