Study Notes
Managerial Economics Lecture Notes
- The lecture covers quantitative demand and supply analysis, specifically elasticity and its applications.
- The elasticity concept assesses the responsiveness of a variable to changes in another.
- Own price elasticity measures the percentage change in quantity demanded of a good in response to a percentage change in its price.
- Elasticity and total revenue are related: for elastic goods, price decreases increase total revenue; for inelastic goods, price decreases decrease total revenue.
- Cross-price elasticity measures how the demand for one good changes due to a change in the price of another good.
- Substitutes have positive cross-price elasticity; complements have negative cross-price elasticity.
- Income elasticity measures how demand changes with changes in consumer income.
- Normal goods have positive income elasticity; inferior goods have negative income elasticity.
- Demand functions are mathematical representations of how demand is linked to price and other factors.
- Linear and log-linear demand functions are presented as examples.
- Regression analysis helps estimate demand and supply functions from real-world data.
- Elasticity helps in pricing decisions, managing cash flows, adjusting to competitor price changes, and assessing the impact of advertising campaigns.
- The lecture discussed quantitative questions like the effect of price cuts on sales, rival price changes, and economic downturns on sales.
- Different demand scenarios were shown with diagrams, showing elastic, inelastic, and unit elastic demand scenarios.
- The slides discuss the own price elasticity formula and interpreting the elasticity value in relation to the law of demand.
- Slides detail factors influencing price elasticity such as availability of substitutes, time, expenditure share, number of uses, number of new buyers, addictive nature, and luxury versus necessity.
- Price elasticity and its relation to total revenue is highlighted showing the different scenarios where a price increase or decrease will increase or decrease total revenue.
- Calculating the Own Price Elasticity of Demand.
