The document discusses market demand and supply theories for potatoes. It shows the market demand curve shifting outward from D0 to D1, representing an increase in demand. The supply curve is also shown shifting outward from a to b to c to d to e, representing an increase in supply quantities at each given price level. The intersection of supply and demand determines the market equilibrium price and quantity.

Pengaruh Dimensi
Waktu terhadap
Keseimbangan Pasar

44. Dimensi Waktu Penawaran
Berdasarkan dimensi waktunya, pasar
dikelompokkan menjadi 3 jenis yaitu:
1. Pasar seketika atau immediate market
2. Pasar jangka pendek atau short-run
market
3. Pasar jangka panjang atau long-run
market

45. Pasar Seketika atau Immediate Market
Pasar seketika merupakan periode pasar
yang demikian pendeknya hingga tidak
memungkinkan bagi produsen untuk
mengubah jumlah hasil produksinya.
Kuantitas suply yang ditawarkan adalah tetap

46. Pasar Jangka Pendek atau Short-run Market
Pasar Jangka Pendek merupakan periode pasar dimana
produsen telah dapat memperbaiki hasil produksinya, tetapi
belum cukup waktu untuk mengubah skala produksi. Dan di
samping itu belum memungkinkan untuk masuknya produsen
baru dalam pasar
Kuantitas suply yang ditawarkan mengikuti hukum penawaran
dan cenderung inelastis

47. Pasar Jangka Panjang atau Long-run Market
Pasar Jangka Panjang merupakan periode pasar
dimana produsen telah memiliki cukup waktu untuk
mengubah skala produksi. Dan memungkinkan
masuknya produsen baru dalam pasar
Kuantitas suply yang ditawarkan mengikuti hukum
penawaran dan cenderung elastis
