The marginal cost curve is the change in total costs as output changes.
Marginal Cost = Change in Total Cost / Change in Output
Total Revenue (TR) = Price x Quantity Sold
Total Revenue (TR) is the amount received from selling goods or services, calculated by multiplying price per unit by quantity sold.
Average revenue (AR) = TR/QS
Average revenue (AR) is the average amount received per unit sold, calculated by dividing total revenue by the number of units sold.
Price elasticity of demand measures how sensitive consumers are to changes in price, with values greater than one indicating that percentage change in quantity demanded exceeds percentage change in price.
Price elasticity of demand (PED) = % change in QS / % change in price
Income elasticity of demand (YED) = % change in QS / % change in income
Income elasticity of demand measures how responsive consumer demand is to income changes, with positive values indicating that an increase in income leads to an increase in consumption.
% Change in QS = [(New QS - Old QS)/Old QS] * 100%
Income elasticity of demand measures how responsive consumer demand is to income levels, with positive values indicating that an increase in income leads to increased consumption.
% Change in QS = [(New QS - Old QS) / Old QS] * 100%
Cross-price elasticity of demand (XED) = % change in QS1 / % change in P2
% Change in price = [(New price - old price) / old price] * 100%
% Change in price = [(New price - old price)/old price] * 100%
If PED is less than 1, it means that the product is relatively inelastic as the percentage change in quantity demanded is smaller than the percentage change in price.
If PED is less than 1, it means that the product is relatively inelastic, meaning that there will be little effect on sales if prices increase slightly.
Economies of scale occur when increasing output results in lower costs per unit due to spreading fixed costs over more units produced.
Economies of scale occur when increasing output results in lower average costs due to spreading fixed costs over more units produced.
The law of diminishing marginal utility states that as consumption increases, additional units will bring less satisfaction.
Cross-price elasticity of demand (XED) = % change in QS / % change in Px
% Change in Price = [(New Price - Old Price)/Old Price] * 100%
