    Study Notes

    Revenue Concepts

    • Total Revenue (TR): The total amount of money a firm receives from the sale of goods or services during a specific time period. Calculated as: TR = Q * P, where Q is quantity and P is price per unit.
    • Average Revenue (AR): The revenue earned per unit of output sold. Calculated as: AR = TR/Q = P. Essentially, the average revenue is the same as the price.
    • Marginal Revenue (MR): The revenue a firm gains from producing one additional unit of a commodity. Calculated as the difference in total revenue before and after the increase in production. MR can also be calculated as the change in TR (dTR) divided by the change in quantity (dQ). MR = dTR/dQ; or MR(Q)= TR(Q) -TR(Q-1).

    Factors Affecting Supply

    • Price of the commodity: As price increases, supply generally increases (direct relationship)
    • Cost of Production: Lower production costs tend to increase supply, whereas higher costs decrease it.
    • Expectation about future prices: If prices are expected to rise, current supply may decrease as producers hold off on selling.
    • Technological Advancement: Improvements in technology may increase output and thus supply.
    • Number of Sellers: A greater number of sellers typically leads to a greater supply.
    • Government Policies: Policies such as subsidies or taxes influence supply by changing the profitability of production.
    • Goals of firms: Profit maximization or sales growth impact a firm's decision to increase/decrease supply.
    • Price of Related Goods: Prices of related goods can influence the supply through substitution effects(if a related product price increases, supply of the affected product also increases)
    • Infrastructure: More efficient infrastructure can ease the flow of goods to market and increase supply.

    Law of Supply

    • The higher the price of a good, the greater the quantity supplied, assuming other factors remain constant.
    • There is a direct relationship between price and quantity supplied.

    Exceptions to the Law of Supply

    • Backward Bending Labor Supply Curve: After a certain wage, workers may choose to work less (supply less labor) as income increases and the opportunity cost of leisure increases.
    • Perishable Goods: Supply of perishable goods can increase even when prices decline, driven by the need to sell goods before spoilage.
    • Monopoly: A single seller might decrease the supply to maintain higher prices (instead of increasing with higher prices like in other market structures).
    • Stock Clearance: Firms might increase the supply even at lower prices to sell remaining stock.
    • Closure of firm: A firm closing might sell more to liquidate their stock at lower prices.

    Market

    • Market Equilibrium: the point where the demand curve and the supply curve meet, establishing the equilibrium price and quantity.
    • Market Equilibrium Graph: A graph illustrating the market equilibrium, where the demand and supply curves cross at a point that shows an equilibrium.
    • Excess Demand: If the price is lower than the equilibrium price, demand will exceed supply, pushing the price upward toward the equilibrium level.
    • Excess Supply: If the price is higher than the equilibrium price, supply will exceed demand, pushing the price downward toward the equilibrium level.

    Market Structures

    • Perfect Competition: Large number of buyers and sellers, homogeneous products, easy entry and exit, no single seller has control over prices.
    • Monopoly: Single seller, no close substitutes, high barriers to entry, significant control over prices.
    • Monopolistic Competition: Many sellers, differentiated products, some control over prices, relatively easy entry and exit.
    • Oligopoly: Small number of large sellers, either homogeneous or differentiated products, high barriers to entry, significant interdependence among firms.

    Elasticity of Supply

    • Measures the responsiveness of quantity supplied to a change in price. Calculated as: Es = (% Change in Quantity Supplied) / (% Change in Price).
