Demand, Supply, and Equilibrium Price Concepts
📌 The discussion covers the economic concepts of demand, supply, and equilibrium price, foundational elements in understanding transactions and pricing.
⚖️ Human beings are described as *homo economicus*, constantly striving to meet needs through activities like buying and selling, where these three concepts significantly influence each other.
📈 An example cited is the surge in staple food prices before holidays, primarily driven by a high level of public demand.

Factors Influencing Demand
💰 Demand is defined as the quantity of goods consumers request at a specific price and time, influenced by several factors, including price of the good (inverse relationship) and income levels (higher income leads to higher purchasing power and demand).
👗 Other factors include consumer tastes/trends (often called 'fashion'), quality of the goods, and the price of related goods (substitutes or complements, like switching from Pertamax to Pertalite due to price differences).
👨‍👩‍👧‍👦 The population size directly impacts demand; for instance, a family growing larger necessitates increased demand for necessities.
🔮 Future expectations, such as anticipating a rise in fuel prices (BBM), cause immediate spikes in current demand as people rush to buy before the price change.

Law of Demand and Supply
📉 The Law of Demand states that as the price of a good decreases, the quantity demanded increases, and vice versa; the demand curve generally slopes downward from left to right.
🏭 Supply is the quantity offered by sellers at a specific price and time, influenced by production costs (higher costs limit supply, especially for luxury items).
📈 The Law of Supply dictates that as the offering price rises, the quantity supplied increases, causing the supply curve to generally slope upward from left to right.
⚙️ Technological level is crucial for supply; machine-based production allows for much higher output volumes compared to relying solely on manual labor.

Equilibrium Price Determination
🤝 Equilibrium price is the agreed-upon price resulting from direct negotiation, often observed in traditional markets where buyers try to push the offer price up while sellers try to pull the asking price down.
🎯 This point of agreement, reached after bargaining between the buyer's raised offer and the seller's lowered counter-offer, establishes the final negotiated price.

Key Points & Insights
➡️ Demand is fundamentally linked to purchasing power: Higher consumer income generally translates directly to increased demand for goods and services.
➡️ Producers react to profit motive: Sellers increase production and expand operations based on the hope of earning higher profits (laba).
➡️ Equilibrium is achieved through negotiation: The final market price reflects a meeting point of desires between consumers seeking lower prices and sellers seeking higher returns.
