True or False?
PED is usually a positive value.
False.
PED is always negative because of the inverse relationship between price and quantity demanded. When price rises, quantity demanded falls, and when price falls, quantity demanded rises.
How is a percentage change calculated?
A percentage change is calculated using this formula:
% change = (New value − Old value) ÷ Old value × 100

Define price elasticity of demand (PED).
Price elasticity of demand (PED) measures how responsive demand for a product is to a change in price.
PED = % change in quantity demanded ÷ % change in price
True or False?
PED is usually a positive value.
False.
PED is always negative because of the inverse relationship between price and quantity demanded. When price rises, quantity demanded falls, and when price falls, quantity demanded rises.
How is a percentage change calculated?
A percentage change is calculated using this formula:
% change = (New value − Old value) ÷ Old value × 100
A business raises the price of a product from $24 to $30 and expects demand to fall by 12%. What is the PED?
The price rises by 25%, so PED = −12% ÷ 25% = −0.48.
What does a PED value of −1.2 show about demand for a product?
A PED of −1.2 shows that demand is price elastic. For every 1% change in price, demand changes by more than 1%.
True or False?
A PED value of −0.7 means demand is price elastic.
False.
A PED between 0 and −1 means demand is price inelastic. For every 1% change in price, demand changes by less than 1%.
What happens to total revenue when a business raises the price of a product with price elastic demand?
Total revenue falls, because the percentage fall in demand is greater than the percentage rise in price.
True or False?
Lowering the price of a product with price inelastic demand reduces total revenue.
True.
Demand rises by a smaller percentage than the price falls, so the extra sales do not make up for the lower price and total revenue falls.
Price ______ strategies are best employed for products that are price inelastic in demand.
Price skimming strategies are best employed for products that are price inelastic in demand.
Which type of pricing strategy is best employed for products with price elastic demand?
Competitive pricing strategies are best employed for products with price elastic demand.
Why is PED of limited use for new products?
There is no past sales data, so it is hard to estimate how price changes will affect demand for a product that has not been sold before.
True or False?
A product's PED stays fixed over time.
False.
PED can change as customer preferences or incomes change. Demand may be inelastic in the short term but more elastic in the long term as customers adjust.
Why does ignoring competitor actions limit the usefulness of PED?
PED does not consider how rivals respond to a price change. If rivals also cut their prices, demand may stay unchanged.
Why is the assumption that other factors stay the same a limitation of PED?
PED only looks at price and demand, but factors such as income, trends and marketing also affect sales, so actual demand may differ from the prediction.
Define income elasticity of demand (YED).
Income elasticity of demand (YED) measures the responsiveness of demand for a product to a change in income levels.
YED = % change in quantity demanded ÷ % change in income
Define normal good.
A normal good is a good where demand rises when income increases.
True or False?
Demand for a luxury good rises at the same rate as income.
False.
Demand for a luxury good increases more than proportionally as income increases, so its YED is greater than 1.
What type of good has a negative YED value?
A good with a negative YED value is an inferior good. Demand for it falls when income rises and rises when income falls.
What does a YED value between 0 and 1 show about a good?
A YED between 0 and 1 shows a necessity good. Demand changes only slightly when income changes, so it is income inelastic.
A person's weekly income falls from $450 to $405, and their demand for takeaway meals falls from 50 to 30 per week. What is the YED?
Quantity demanded falls by 40% and income falls by 10%, so YED = −40% ÷ −10% = 4.
True or False?
During a recession, demand for inferior goods usually rises.
True.
Wages usually fall in a recession, so demand for inferior goods rises while demand for luxury goods falls.
Why might a business lower prices on a product with a high positive YED during an economic downturn?
As incomes fall, demand for products with a high positive YED may fall sharply, so lower prices or discounts may be needed to maintain sales.
Why can businesses selling necessities often keep prices the same during an economic downturn?
Necessities have a low YED close to zero, so demand is less sensitive to income and stays fairly stable when incomes fall.
How can knowing a product's YED help with capacity planning?
A business can expand capacity for products with a positive YED when incomes are rising, and for inferior goods when incomes are falling, so it can meet the expected change in demand.
Why does the difficulty of predicting income changes limit the usefulness of YED?
It is hard to know when or by how much incomes will rise or fall, so demand forecasts based on YED may be wrong.
True or False?
YED data applies equally to all of a business's customers.
False.
Different customer groups react differently, because not everyone's income changes in the same way. Average YED data may include groups the business does not target.
YED may be misleading in the short term because customers often ___ spending after a change in income.
YED may be misleading in the short term because customers often delay spending after a change in income.
Why might a product's YED classification change over time?
A product seen as a luxury today might become a necessity later. For example, smartphones were once luxuries but are now widely considered essential.
Define promotional elasticity of demand.
Promotional elasticity of demand measures the responsiveness of demand for a product to a change in the amount of money spent on promoting it.
Promotional elasticity of demand = % change in quantity demanded ÷ % change in promotional spending
What can businesses use promotional elasticity of demand to decide?
It helps decide whether extra promotional spending is worthwhile, the effect on demand of cutting promotional spending and the best use of promotional budgets.
How is the outcome of the promotional elasticity of demand formula expressed?
It is expressed as a ratio, such as 1.2 : 1, showing the percentage change in demand for each 1% change in promotional spending.
A business spends $2.4 million a year on promotion. It plans an extra $600,000 campaign that it expects to increase sales by 30%. What is the promotional elasticity of demand?
Promotional spending rises by 25%, so promotional elasticity of demand = 30% ÷ 25% = 1.2 : 1.
True or False?
A promotional elasticity of demand below 1 means extra promotional spending is likely to be worthwhile.
False.
A value below 1 means demand is unresponsive (inelastic), so demand rises by a smaller percentage than spending. Extra spending is unlikely to be worthwhile.
When promotional elasticity of demand is less than 1, reducing promotional spending may be an effective way to cut ___.
When promotional elasticity of demand is less than 1, reducing promotional spending may be an effective way to cut costs.
What does a promotional elasticity of demand greater than 1 show?
It shows that demand is responsive (elastic), because the percentage change in demand is greater than the percentage change in promotional spending.
True or False?
Cutting promotional spending on a product with a promotional elasticity of demand above 1 could cause a significant drop in demand.
True.
Demand is responsive to promotional spending, so a cut could cause a significant fall in sales and may be best avoided.
When comparing promotional options, which should a business usually focus its budget on?
It should usually focus spending on the option with the highest promotional elasticity of demand, as this is most likely to increase sales.
Why should a business not choose a promotional option using promotional elasticity of demand alone?
Promotional elasticity of demand does not take into account the cost and affordability of each option, so a cheaper combination of options may achieve better results.
Why might promotional elasticity of demand undervalue a campaign aimed at building the brand?
Some promotions aim to build brand strength or customer loyalty, which may not show up in short-term changes in demand.
True or False?
It is easy to measure the impact of one campaign when a business promotes many products at once.
False.
When several products are promoted at once, it is hard to separate how much of the change in demand came from one campaign.
Apart from promotion, what other factors can affect demand while a promotion is running?
Changes in taste, word-of-mouth and competitor actions can all influence sales during a promotion.
How can new product development help a business spread risk?
Extra product lines spread risk across different market segments, so the business is less reliant on one product.
True or False?
Regular product innovation can improve a business's brand image.
True.
Launching fresh products regularly can improve brand image, for example by showing a business's commitment to sustainability.
How do technology advances influence new product development?
New technology unlocks features that were impossible before, which can prompt ideas for new products.
What happens at the select the best idea stage of the product development process?
Ideas are compared and some are dropped, with the decision based mainly on costs and likely demand, using forecast sales, market share and cost-benefit analysis.
Developing a _______ allows the operations department to see how a product can be manufactured and fix any production problems.
Developing a prototype allows the operations department to see how a product can be manufactured and fix any production problems.
What is a test launch?
A test launch is when a product is sold on a small scale to a limited market to see how well it sells before an expensive full launch.
True or False?
Running a beta version of an app is a method of test launching.
True.
Digital products such as apps and software run beta versions to test them with users before the full launch.
How can employees be a source of ideas for product development?
Staff in sales, customer service or production often notice problems or spot opportunities for new products.
How can suppliers be a source of ideas for product development?
A supplier might offer new materials or production methods that help create a new product.
True or False?
Competitors are not a useful source of new product ideas.
False.
Looking at what rivals are offering can inspire new ideas or reveal gaps in the market.
How does market research help generate ideas for new products?
Surveys, focus groups and trend analysis help a business understand customer needs and spot new opportunities.
How does product development help a business stay competitive?
It allows the business to keep up with changes in customer preferences and technology, so it can stay ahead of rivals.
How can new products support business growth?
New products can open up new markets or increase sales, helping the business grow in size and profits.
How can product development build customer loyalty?
Offering fresh and useful products shows customers that the business listens and adapts to their needs, which strengthens the brand.
Define sales forecast.
A sales forecast is a prediction of future sales revenues based on past sales figures.
What resource requirements can sales forecasts help a business determine?
They help determine how many staff are needed, how much inventory is required and whether capacity needs to be expanded or reduced.
True or False?
Sales forecasts can improve the validity of cash flow forecasts.
True.
Sales forecasts are an important tool to support planning, and they improve the validity of cash flow forecasts.
Why do businesses use time series analysis when forecasting sales?
Raw sales data can be volatile, making patterns hard to spot, so time series analysis smooths the data to make future sales easier to predict.
A three-month moving average is found by dividing each three-month __________ by 3.
A three-month moving average is found by dividing each three-month moving total by 3.
Sales for January, February and March are 15,425, 9,647 and 12,379. What is the three-month moving average for this period?
The three sales figures add up to 37,451, so the three-month moving average is 37,451 ÷ 3 = 12,484, placed alongside February.
How should a line of best fit be drawn through plotted moving averages?
It should have as many data points above the line as below it, adjusted up or down if there is more than one outlier on one side.
How is a line of best fit used to forecast future sales?
The line of best fit is extended (extrapolated) beyond the existing data to predict future sales values.
Define qualitative sales forecasting.
Qualitative sales forecasting is predicting future sales using non-numerical data, such as expert opinions, market experience or customer feedback.
What is a sales force estimate?
A sales force estimate is a forecast made by sales staff based on their direct interaction with customers.
True or False?
Qualitative sales forecasting is more accurate than quantitative methods.
False.
Qualitative forecasting is usually less accurate, because it is subjective and prone to bias and is not based on numerical data.
When is qualitative sales forecasting especially useful?
It is especially useful when a business launches a new product with no past sales data, or enters a new market.
How can sales forecasting help the human resources function?
It helps plan recruitment, training and staff scheduling, and avoids overstaffing when lower demand is forecast.
How can sales forecasting help the operations function?
It ensures the right amount is produced to meet expected demand, helping to prevent overproduction or shortages of inventory.
