Sierra, one thing happens and everything moves

Let us say that your colour wholesaler puts the colour for a full head of foils up from $28.00 to $35.00. Today you follow what that does to Five Star's profit, and then to everyone Five Star deals with.

Thirteen sections, about 80 minutes all up. One section is one sitting. Do that one and stop.

01

Before we start

Recall3 min

Three from the lessons so far. Have a go before you open them.

1How many sentences does the exam's minimum of three relationships take?

Three relationships take six sentences. Each relationship takes two sentences, one starting with each participant's name.

2Why does “the wholesaler was affected” not achieve?

“The wholesaler was affected” does not achieve because the sentence gives no direction. Say increased or decreased, and say which money it was: sales revenue, wages, rent, interest or tax.

3A cake shop sells 100 cakes in a week at $5.00 each, and its expenses for the week are $300.00. What is the cake shop's profit?

The cake shop's profit is $200.00 for the week. Sales revenue is 100 cakes × $5.00, which is $500.00. Take the $300.00 of expenses off that and $200.00 is left.

02

What is an event?

Learn3 min

An event is something that happens that has economic significance to an organisation.

✓ Good newsA business that builds roads wins a new government contract.
✓ Good newsA donut store gets busy through social media.
✗ Bad newsA seafood business finds its overseas orders have dried up.

All three examples have been the event in a real exam. Good news or bad, an event is a change big enough to move money.

03

Today's event

Learn2 min

Today's event is a price rise: the colour for one foil job goes up by $7.00.

COLOUR FOR ONE JOB $28.00 $35.00
Five Star's colour wholesaler puts the price of the colour up from $28.00 to $35.00 a job.

Everything in the rest of this lesson comes out of that one price rise.

04

Direct effect

Learn6 min

The direct effect is what the event does straight away, with nothing else between the event and the direct effect.

Five Star still does 12 full heads of foils a week, and the colour for each one now costs $7.00 more: $420.00 a week instead of $336.00.

Five Star's week, before and after the colour price rise
BeforeAfter
Colour$336.0012 foil jobs × $28.00$420.0012 foil jobs × $35.00
Power, water and laundry$144.0012 foil jobs × $12.00$144.0012 foil jobs × $12.00
Sanjay's pay and the rent$1,560.00$1,560.00
Total expenses$2,040.00$2,124.00
Sales revenue$2,280.00$2,280.00
Profit$240.00$156.00
THE SAME $2,280.00 OF SALES REVENUE, BOTH WEEKS Before $2,040.00 expenses $240.00 profit After $2,124.00 expenses $156.00 profit
Revenue never moved. The whole $84.00 came out of the profit.

Here are two ways to describe the direct effect of the colour wholesaler's price increase:

Marker's rule

Write one direct effect, not two opposing ones.

Five Star's expenses increased by $84.00 a week.

Five Star's expenses increased, but its sales revenue increased too. Five Star's sales revenue increases only if Five Star does more foils, and the price rise brought no extra foils.

The direct effect, written“Five Star's expenses increased by $84.00 a week, so its profit decreased from $240.00 to $156.00.”

No direction, no figures“Five Star's expenses were affected by the colour price rise, so its profit was affected as well.”“Affected” gives no direction and no figure. Say that the expenses increased by $84.00 a week, and what the profit fell from and to.

05

Flow-on effect

Learn4 min

A flow-on effect is a second round of effects following a direct effect.

Press Show the next step to follow the money out from the price rise, one round at a time.

  1. 1The event
    The colour wholesaler puts a job's colour up from $28.00 to $35.00.
  2. 2First round: the direct effect, on both sides

    Five Star's expenses increase by $84.00 a week, so its profit decreases from $240.00 to $156.00. The same $84.00 increases the colour wholesaler's sales revenue.

    Why this is still the first round: the price rise is one transaction between two participants, Five Star and the colour wholesaler.

  3. 3Second round: the flow-on effects

    The government receives less tax revenue from Five Star, because there is less profit to tax, and more tax revenue from the colour wholesaler, because the wholesaler's profit went up by the same $84.00.

    THE EVENT the colour wholesaler $28.00 → $35.00 FIRST ROUND Five Star profit $240.00 → $156.00 SECOND ROUND the government LESS TAX FROM FIVE STAR AND MORE TAX FROM THE WHOLESALER
Step 1 of 3
Marker's rule

A direct effect is the first round after the event. A flow-on effect is the second round, and it belongs to a different entity from the first.

The direct effect is on Five Star: its expenses increase by $84.00 a week. The flow-on effect is on the government, which receives less tax from Five Star.

The flow-on effect is that Five Star's profit falls.

06

Writing a flow-on effect

Learn4 min

To write a flow-on effect, say what happened to the money, then say what that change did to the relationship.

Marker’s rule

Link every flow-on effect to the relationship it changes, and say how both participants in that relationship are affected.

1) Stopping at the participant

Followed back to the relationship“The government receives less tax revenue from Five Star, so Five Star is putting less towards the roads and services it uses itself. That weakens the relationship: Five Star pays tax, and the government provides those services.”

No relationship“The government receives less tax revenue from Five Star.”The sentence stops at the government. Follow the tax back to the relationship between Five Star and the government.

2) Naming the relationship without the money

Money, then strength“The government receives less tax revenue from Five Star, because Five Star's profit fell by $84.00. That weakens the relationship: Five Star pays tax, and the government provides the services Five Star uses.”

Strength, no money“The relationship between Five Star and the government is weaker now.”The sentence says the relationship is weaker but not why. Write the money first: the government receives less tax revenue.

Write the money first and the relationship second, one relationship at a time.

07

From the event to the consequence

Learn6 min

After the price rise, Sierra has to decide what Five Star does next.

Five Star's profit has fallen by $84.00 a week. Press what Sierra could decide, and see what follows.

Sierra cuts Sanjay from forty hours a week to thirty-six. Sanjay earns $96.00 a week less, so his household spends less at the businesses it buys from.

Each of these choices is a response: a decision Sierra makes because of what the event did. Sierra could have chosen any one of the three choices.

Three different decisions, three different results. If you can name a different thing the person could have done, you are looking at a response, not an effect. What follows a response is called a consequence.

The whole chain

Press Show the next step to walk from the price rise to the consequences of Sierra's decision.

  1. 1The event
    The colour wholesaler puts a job's colour up from $28.00 to $35.00.
  2. 2The direct effect
    Five Star's expenses increase by $84.00 a week, so its profit decreases from $240.00 to $156.00.
  3. 3The flow-on effect
    The government receives less tax revenue from Five Star, because there is less profit to tax.
  4. 4The response
    Sierra cuts Sanjay's hours from forty a week to thirty-six.
  5. 5The consequences
    Sanjay is paid for four hours a week less, so his household spends less at the businesses it buys from.
Step 1 of 5
Marker's rule

Cut the hours, and leave the hourly rate alone. Sierra cuts Sanjay's hours; what Sanjay earns an hour does not move.

Sanjay works four hours a week less.

Sanjay's wage rate decreases.

08

The cyclone answer: Achieved, Merit, Excellence

Learn11 min

Here is one exam answer about a cyclone and an orchard, built up step by step.

Press Show the next step to follow the cyclone from the event to the consequences.

  1. 1The event
    A cyclone damages an apple orchard.
  2. 2The direct effect
    The orchard loses income from the sale of its apples.
  3. 3The flow-on effect
    The Government receives less tax revenue from the orchard, so the Government has less to spend on the road to the orchard.
  4. 4The response
    The Government delays projects in other parts of the country, so that the road to the orchard is still upgraded.
  5. 5The consequences

    Good: the orchard pays less to get its apples to market.

    Bad: the construction firms booked for the delayed projects lose that work, so their workers' hours are cut.

Step 1 of 5

Now, let's look at how the above chain can be written about. Press each grade to see what it adds.

“The cyclone damaged the orchard, so the orchard lost potential income from the sale of their apples.”

Achieved: the event, and what it did to one participant, in money.

You are not writing a different answer for a higher grade. You are writing a longer answer.
Marker's rule

Follow each consequence through to future income or profit, purchasing power, or the ability to complete a service, and say how long the impact lasts.

What made the cyclone answer Excellence

The answer has to explain how a decision changes at least one of three things. The cyclone answer covers two.

💰 Future income or profit“…can rebuild the income the cyclone cost”, “…so their revenue falls”

🛒 Purchasing power“…earn lower wages and spend less at the businesses they buy from”

🔧 Ability to complete a serviceNobody in the answer stops being able to do their work, and that is fine.

The top grade also asks how long the changes last, so the answer ends with for as long as the projects stay delayed.

09

Direct, flow-on, response, or consequence?

Practise10 min

These seven sentences are all about the colour price rise. Choose what each one is.

“Five Star's expenses increased by $84.00 a week.”

That is a direct, first-round effect. The colour price went up and the expense went up. Nothing happened between the event and the effect.

“The government receives less tax revenue from Five Star.”

That is a flow-on, second-round effect. The profit had to fall first. You can write the sentence that goes in front of it, and that is what makes it flow-on.

“The colour wholesaler's sales revenue increases by $84.00 a week from Five Star alone.”

That is a direct, first-round effect, and an easy one to misfile, because it is good news for somebody else. The same price rise that increased Five Star's expense is the wholesaler's extra revenue: one event, two participants, and no step between the event and the effect.

“The government receives more tax revenue from the colour wholesaler.”

That is a flow-on, second-round effect, and it moves the opposite way to the tax from Five Star. The wholesaler's revenue had to rise first, and then its profit, before there was more to tax. One event can move the same participant's money in both directions at once.

“Sierra cuts Sanjay's hours from forty a week to thirty-six.”

That is a response, a decision Sierra made because the profit fell. Nothing about the event forced it: she could have absorbed the $84.00 or put her own prices up instead.

That is what separates a response from an effect. An effect happens to you; a response is chosen. Responses belong at Excellence, where the decision has to be justified and its consequences discussed.

“Five Star's profit decreased from $240.00 to $156.00.”

That is a direct, first-round effect. Revenue did not move and no other expense moved, so the whole $84.00 came straight out of the profit in the same breath as the expense went up.

“Sanjay has less to spend at the shops in town.”

That is a consequence, because it follows a response rather than the event. Trace it back: the profit fell, then Sierra decided to cut the hours, then his wage income fell, and only then does this happen. Because a decision sits in the chain, it is a consequence of that decision rather than a flow-on effect of the event.

That sentence is still worth writing, because it reaches purchasing power. That sentence belongs in the Excellence part of your answer.

10

Fair questions

Learn6 min

The questions this lesson makes people ask, answered simply.

1“Stronger” is not a direction. So why am I told to write “weakens the relationship”?

Because the relationship clause comes after the money, never instead of it. Write the money first and the relationship second.

Money, then the relationship“The Government receives less tax revenue from the orchard, which weakens the relationship where the orchard pays tax and the Government provides infrastructure it depends on.”

Strength instead of money“The relationship between the orchard and the Government is weaker.”The sentence gives the strength of the relationship but no money. Write the money first, then the relationship.

2How many flow-on effects do I need?

You need enough flow-on effects to cover the relationships the question asks about, which will be at least three. One flow-on effect per relationship, each followed back to that relationship, covers what the question asks.

3Can a flow-on effect be good news?

Yes, a flow-on effect can be good news. The colour wholesaler's sales revenue increases by $84.00 a week, which is a direct effect. The government then receives more tax from the wholesaler, which is a flow-on effect, because the wholesaler's profit had to rise first.

4What if I cannot tell whether an effect is first round or second?

Ask what had to happen first. If something else had to change before the effect, the effect is second round. If only the event came before the effect, the effect is first round.

Second round“The government receives less tax revenue from Five Star.” Five Star's profit had to fall first, so a sentence goes in front of it: “Five Star's profit decreased from $240.00 to $156.00.”

First round“Five Star's expenses increased by $84.00 a week.” Nothing goes in front of that except the event itself, the colour going up from $28.00 to $35.00.

5When Five Star chose to pay for the website, the consequence came first and then the response. Here the response comes first. Which way round is it?

Whether the consequence or the response comes first depends on what starts the chain. A chain that starts with Five Star's own decision has the consequence first: the consequence follows the decision, and a response then deals with the consequence. A chain that starts with an event has the response first: the response is Sierra's decision about the event, and the consequences follow that decision.

The chain starts with a decision: paying for the websiteConsequence: the website's $45.00 a month comes out of the same profit the new bookings are building, so the gain gets smaller. Response: add up the new clients after a year, and stop paying if hardly any came through.

The chain starts with an event: the colour price riseResponse: Sierra cuts Sanjay's hours from forty a week to thirty-six. Consequences: Sanjay is paid for four hours a week less, so his household spends less at the businesses it buys from.

Marker's rule

Justify the response with its reason. Then discuss its consequences, good and bad.

The government spends the money to create jobs and reduce unemployment.

The government spends the money, so some people are better off and some are worse off.

Six ways to lose a mark

Practise6 min

Work out what is wrong before you open the answer.

1The direct effect is that the government gets less tax from Five Star.What would a marker say?

The problem. That is a flow-on effect wearing a direct effect's label. Something had to happen first: the profit had to fall before there was less to tax.

Do this instead

“Five Star's expenses increased by $84.00 a week, so its profit decreased from $240.00 to $156.00.”

The direct effect is the one with nothing between the event and the effect.

2Because the profit fell, the government receives less tax revenue from Five Star.What would a marker say?

The problem. Nothing here is wrong, but the sentence stops one clause short: it never says what this does to a relationship.

One report: students “identified positive and negative consequences for different participants, however then did not link this to a relevant interdependent financial relationship.”

Do this instead

“Because the profit fell, the government receives less tax revenue from Five Star, which weakens the relationship where Five Star pays tax and the government provides the roads and services the salon uses.”

Add the clause. The clause names both sides of the relationship, after the money.

3There is now a stronger relationship between Five Star and its colour wholesaler.What would a marker say?

The problem. This is the opposite fault to stopping at the money. The relationship is named, but the money is gone: no amount, no direction, nothing a marker can check.

The report on this exam says Merit answers wrote the direction of the money rather than the strength of a relationship.

Do this instead

“The colour wholesaler receives $84.00 a week more in sales revenue from Five Star, which strengthens the relationship where the wholesaler supplies the colour and Five Star pays for it.”

Write the money first and the relationship second.

4Sanjay might have his hours cut.What would a marker say?

The problem. That consequence is true, and it never says what happens to Sanjay's own money. An answer has to explain how the decision could impact “future income or profit, purchasing power, or the ability to complete a service”.

None of those three effects appears in that sentence.

Do this instead

“Sanjay might have his hours cut, so Sanjay's wage income falls. His household then has less purchasing power, and the businesses in town he buys from receive less sales revenue.”

Say what happens to one of the three effects.

5Sierra should cut Sanjay's hours, which would fix the problem.What would a marker say?

The problem. That sentence is a decision with no reason, and “fix the problem” is not a financial statement. To justify a response, give the figures that show what the response saves against what the event cost.

Do this instead

“Cutting Sanjay from forty hours a week to thirty-six saves $96.00 a week against the $84.00 the colour rise costs, so the profit goes to $252.00 rather than $156.00.”

Show the arithmetic that makes it right.

Then compare the two figures: the cut saves $12.00 a week more than the price rise costs.

6Cutting Sanjay's hours puts Five Star's profit back to $240.00, so the decision works.What would a marker say?

The problem. That is wrong twice. The arithmetic is wrong first. The cut saves $96.00 a week, and the colour now costs $84.00 a week more. That leaves the profit at $252.00, which is $12.00 more than the week made before the colour went up. The cut overshoots.

And it gives one sign only. Every consequence in it is good, which means the answer has looked at one participant and stopped. Sanjay is paying $96.00 a week for it and he is not in the sentence.

Do this instead

“The profit goes to $252.00, $12.00 more than before, so the cut more than covers the increase. But Sanjay earns $96.00 a week less, which lowers his household's purchasing power, and with four fewer hours at the basin Five Star may not be able to take every booking.”

Correct the figure, then add the other side and what follows later.

Three of these six mistakes are not wrong. They are short. The sentence is true, and it stops one clause before the mark. For those three cards, finish the sentence.

The words from today

Reference5 min

These are the words this lesson taught. Read direct effect and flow-on effect together, so you can tell them apart.

“Something that happens that has economic significance to an organisation.” A change in market conditions, a natural event, or a change for a stakeholder. An event does not have to be bad news.

An eventThe colour wholesaler putting a job's colour up from $28.00 to $35.00.

Not an event (but a change that moves no money)Sierra repainting the salon's front door. Nothing about the money changes.

“A first-round effect following an event.” Nothing happened between the event and the effect.

A direct effect“Five Star's expenses increased by $84.00 a week, so its profit decreased to $156.00.”

Not a direct effect (but a flow-on effect)“The government receives less tax revenue.” The profit had to fall first, so the tax revenue is the second round.

“A second round of effects following a direct effect.” To write a flow-on effect you have to be able to say what came before it.

A flow-on effect“Because the profit fell, the government receives less tax revenue from Five Star.”

Not a flow-on effect (but a direct effect)“The colour cost $84.00 more.” That is the first round, and a flow-on effect is the round after it.

A decision somebody makes because of what the event did. A response and a decision are the same thing. Nobody is forced into a response, and that is the test: if you can name a different thing the person could have done, the sentence is a response and not an effect.

A response“Sierra cuts Sanjay's hours from forty a week to thirty-six.” She could have absorbed the $84.00 instead.

Not a response (but a direct effect)“Five Star's profit decreased to $156.00.” Five Star did not choose that.

What happens after somebody makes a decision. A flow-on effect follows the event; a consequence follows the response.

A consequence“Sanjay is paid for four hours a week less, so Sanjay's household spends less at the businesses it buys from.”

Not a consequence (but a flow-on effect)“The government receives less tax revenue from Five Star.” That follows the event, so it is a flow-on effect.

How much a household can actually buy with what it earns. An answer that says a household's purchasing power fell has explained one of the three things the top grade asks about.

Explains purchasing power“Sierra cuts Sanjay's hours from forty a week to thirty-six, so Sanjay earns $96.00 a week less. The shops in town Sanjay buys from then receive less sales revenue.”

Stops short“Sanjay's hours are cut.” True, but the sentence never says what happens to Sanjay's money.

Your turn

Practise15 min

These five tasks are about Bright Street, not Five Star, because you will be given a business you have not seen before. Bright Street Hair Supply mixes shampoo in a rented unit and sells that shampoo to salons, Five Star among them. Written out one after the other, the five answers are one whole answer.

What you know

Bottles sold in a month400
Price of one bottle$13.00
Expenses, each month$4,740.00
Empty bottles (400 × $1.20)$480.00
Ingredients$1,100.00
Wages for two staff$2,400.00
Rent on the unit$700.00
Interest to the bank$60.00

Name the money that moves for each participant

Every participant here has one money word that moves, and no two are the same. Drag each word onto its participant, or press a word and then press the participant.

THE EVENT a bottle $1.20 → $1.80 FIRST ROUND the plastics company MONEY WORD? Bright Street MONEY WORD? SECOND ROUND the government MONEY WORD? the bank MONEY WORD? A RESPONSE the two staff MONEY WORD?
The rent does not move, so the landlord is not in this picture.
the plastics company

The 60 cents a bottle that became Bright Street's extra expense is the plastics company's extra sales revenue, $240.00 a month. One event, two participants, and nothing between the event and the effect, so this is still the first round.

Bright Street

Expenses rose $240.00 a month while nothing else moved, so the whole of that money came out of the profit. That took the profit from $460.00 down to $220.00, and nothing had to happen first, which is what makes this the first round.

the government

There is less profit to tax, so the government receives less tax revenue. The profit had to fall before that could happen, which makes it the second round.

the bank

The interest is still $60.00 a month. What changed is Bright Street's profit, so name the $60.00 of interest rather than the $15,000.00 loan: the loan moved once and the interest moves every month.

the two staff

If Bright Street cuts its two staff from twelve hours a week to ten, their wage income falls. Somebody decided to cut those hours, so this is a response rather than a flow-on effect of the event.

The event: the plastics company puts an empty bottle up from $1.20 to $1.80. Expenses go from $4,740.00 to $4,980.00 a month. Profit falls to $220.00.

a.Describe the direct effect of the event on Bright Street. Write one sentence that names the money and says which way it moved.

Show me a model answer and how to mark yourself
One that would work

“Bright Street's expenses increased by $240.00 a month, so its profit decreased from $460.00 to $220.00.”

Two money words, each with a direction and a figure, and the sentence stops at the first round.

  • Did you name the money, expenses and profit?
  • Did you give it a direction?
  • Did you stop at the first round? Anything about the government or the bank belongs in part (b).

b.Now write one flow-on effect, and finish the sentence with what that effect does to the relationship. Pick the government or the bank.

Show me a model answer
The government

“Because Bright Street's profit fell to $220.00, the government receives less tax revenue from Bright Street, which weakens the relationship where Bright Street pays tax and the government provides the roads and services the business uses.”

The order earns the mark: the money first, then the relationship, with both sides named.

  • Can you say what came before it? If not, you have written a direct effect, not a flow-on effect.
  • Did you name the money before you mentioned the relationship?
  • Does the last clause name both sides of that relationship?
The bank

“Because Bright Street's profit fell to $220.00, Bright Street has less profit to cover the $60.00 of interest it owes the bank each month. That weakens the relationship where the bank lends Bright Street $15,000.00 and Bright Street pays the bank interest.”

The same order: the fall in profit first, then both sides of the relationship, the loan one way and the interest the other.

c.Bright Street decides to put its own price up from $13.00 to $13.60 a bottle. Justify that decision using the figures.

Show me a model answer
One that would work

“At $13.60 a bottle, 400 bottles bring in $5,440.00 instead of $5,200.00. Against expenses of $4,980.00 that is $460.00 of profit, exactly what Bright Street made before the bottles went up. The $0.60 rise passes the whole increase on and no more.”

A justification is a decision plus the reason it is the right one. The figures are the reason.

d.Write one positive and one negative consequence of that decision, each for a named participant.

Show me a model answer
One that would work

Positively, “Bright Street's profit returns to $460.00, so Bright Street can keep paying the bank its $60.00 of interest and keep both staff on twelve hours a week.”

Negatively, “Every salon that buys from Bright Street now pays $0.60 more a bottle, so Five Star's expenses increase and its profit decreases, and a salon that can buy the same shampoo cheaper somewhere else may stop ordering.”

Each one lands on a named participant's money, and the two point opposite ways, as the question asked.

  • Is each consequence attached to a named participant?
  • Did each one reach money in that participant's hands?

e.Now look past this month. If the bottle price stays at $1.80, what does that mean a year from now?

Show me a model answer
One that would work

“If the salons keep buying 400 bottles at $13.60, Bright Street makes the same $460.00 a month it made before, and a year from now nothing has changed. If enough salons switch to a cheaper supplier, Bright Street's sales revenue falls and its profit falls with it, so Bright Street may have to cut its staff's hours. That lowers those two households' purchasing power, and the businesses they buy from receive less sales revenue in turn.”

The answer follows both ways the year could go, each through to a named participant. The 400 bottles are an assumption, and the answer says so.

That is a whole exam answer, Achieved through Excellence. Open the model answers and mark yourself against the ticks. Be hardest on part (b): check that you named the money before you mentioned the relationship, and that your last clause names both sides of it.
Lesson 7 done

Go Sierra, go!

You took one price rise on one plastic bottle and followed it to a government's tax revenue, a bank's interest, a salon's profit and two households' shopping. That is the whole of your first external, and you have now done it once from end to end.
