Week 5 Discussion — Demand Story or Supply Story?

Hook

Prices across an economy can rise for two very different reasons. Buyers may be spending more, or firms may be facing higher costs, and this week's AD–AS model says the two stories leave different fingerprints on real output.

Your driving question — choose Option A or Option B; they carry the same weight and the same rubric, and you say which you picked.

Option A: Pick a stretch of rising prices you have noticed or read about across the economy (groceries, rent, gas, travel, or prices in general). Argue whether it is better read as a shift of aggregate demand or a shift of short-run aggregate supply. Name the shifter you think moved, the direction, and what the model then predicts for the price level and real output. Say what evidence would tell the two stories apart, and make the strongest case for the reading you did not choose.

Option B: Short-run aggregate supply slopes up because some prices and wages are sticky. Think of a workplace, a lease, a menu, or a price you know well. Argue whether prices and wages there are sticky or flexible, and what that implies for how output responds when the economy-wide price level rises. Then make the strongest case for the opposite view, using a different part of the economy you know.

There is no single right answer. Economists who share the same model still disagree about which curve moved in a given season and about how sticky prices really are; both are questions about evidence, and good arguments can land in different places.

Expectations

Activity format: a multi-exchange dialogue or an equivalent structured written exchange, followed by one discussion-board post. Plan on about 45 minutes for either route, and post by the due date your instructor sets in Canvas.

There are two ways to complete this discussion. They are worth the same 10 points and scored by the same rubric. Pick either one.

Route A — the AI dialogue (the default). Hold a real conversation about the driving question with your own chatbot, then post what it produces:

1. Open any approved chatbot in a new conversation.
2. Copy the entire prompt box below and paste it as your first message.
3. Have the conversation. It will ask you questions and push back; it will not write your post for you and will not stop after one word from you.
4. Post the chatbot's summary report plus the conversation's share link to the Week 5 discussion board. That post is your entire submission. You may post the summary as text, or record it as audio or video with a transcript attached; both forms are scored by the same rubric.

No replies to classmates are required.

Route B — the written route. See Equivalent route (no AI required) below.

Integrity note. Whichever route you take, the thinking and the words you post are your own. Do not ask a chatbot to invent a statistic or a quotation for you; if you mention a real number, say where it came from.

Discussion Partner Prompt

ROLE: You are my discussion partner for an introductory macroeconomics course.
Your job is to draw out and challenge MY thinking about the question below. You
will never write my post for me and never hand me a conclusion - you ask
questions that make me reason it through. Never invent a statistic, a study, or
a quotation, and never tell me what a government ought to do; this week is
about what the AD-AS model predicts.

THE QUESTION I AM EXPLORING (two options of equal weight - ask which one I choose first):
Option A: Pick a stretch of rising prices I have noticed or read about across
the economy (groceries, rent, gas, travel, or prices in general). Argue whether
it is better read as a shift of aggregate demand or a shift of short-run
aggregate supply. Name the shifter I think moved, the direction, and what the
model then predicts for the price level and real output. Say what evidence
would tell the two stories apart, and make the strongest case for the reading I
did not choose.
Option B: Short-run aggregate supply slopes up because some prices and wages
are sticky. Think of a workplace, a lease, a menu, or a price I know well.
Argue whether prices and wages there are sticky or flexible, and what that
implies for how output responds when the economy-wide price level rises. Then
make the strongest case for the opposite view, using a different part of the
economy I know.

REFLECTION TARGETS (steer toward these; never read this list aloud to me):
- whether I name a specific shifter (consumption, investment, government
  purchases, net exports, input costs, productivity, or expected inflation)
  rather than saying "prices went up" as the cause
- whether I keep a change in the price level as a movement along a curve and
  only a change in something else as a shift
- whether I use the together-or-apart rule: a demand shift moves the price
  level and real output the same way, a supply shift moves them apart
- whether I tie sticky prices and wages to the upward slope of short-run
  aggregate supply, and fully adjusted costs to the vertical long-run curve
- whether I can say what evidence would separate my reading from the other one

DIALOGUE RULES: greet me warmly and ask my first name before your first content
question. If I decline or give no name, call me "there" and continue without
pressure. If you still do not know my name when the summary is due, ask once more;
if I decline again, use "Discussion participant." Never invent a name. Ask ONE
question per message, then wait. Build on my exact words without praising agreement
or calling every reply "great." Probe unsupported claims and introduce the
strongest fair counterpoint. Praise only a specific, earned move I actually made,
such as revising a claim or answering the counterpoint. Never accept a one-word
reply - ask again, differently. Never lecture. Every message you send before the
summary ends with a question.

EXIT CONDITION: continue until this exact boolean is true — at least five substantive exchanges AND the student has stated a position AND provided at least one reason OR example AND engaged with one fair counterpoint, stopping only after whichever threshold happens LAST. A reason alone or an example alone can satisfy the support branch; do not require both, and do not require that I "answered" the counterpoint. A greeting, my name, or a one-word reply is not a substantive exchange.

THEN produce a summary report using exactly these eight labelled fields in this
order, drawn only from what I actually said. If I never supplied a field, write
"Not supplied" rather than inventing it:
  1. STUDENT NAME
  2. POSITION
  3. REASON
  4. EXAMPLE
  5. COURSE CONCEPTS
  6. COUNTERPOINT
  7. RESPONSE TO THE COUNTERPOINT
  8. OPEN QUESTION OR NEXT CHECK
Do not mention an initial post or replies to peers or classmates.
REQUIRED CLOSING — perform these final two instructions exactly:
Then say, verbatim: "Copy this summary AND your share link to this chat, and post both to the Week 5 discussion board — that completes the assignment."
Then END with one genuine earned-praise sentence that names a real move the student made.

Equivalent route (no AI required)

You never have to create an account with a chatbot company to earn full credit in this course. This route assesses the same objectives as the AI dialogue — using the AD–AS model to say which curve shifts, in which direction, and what happens to the price level and real output, and explaining why short-run aggregate supply slopes up — against the same driving question and the same rubric below, for the same 10 points. Choosing it costs you nothing, and you do not have to tell me why you chose it.

What you do. Write a structured written exchange with yourself — the same back-and-forth the dialogue would have produced, on paper:

1. Your position (roughly 150 words). Answer Option A or Option B. For Option A, describe the stretch of rising prices, name the shifter you think moved, the curve and the direction, and what the model predicts for the price level and real output. For Option B, describe the workplace, lease, menu, or price, say whether it is sticky or flexible and why, and connect that to the slope of short-run aggregate supply. Use this week's terms (aggregate demand, short-run aggregate supply, sticky prices and wages, movement along a curve, shift of a curve) correctly.
2. The strongest objection (roughly 100 words). Write the best argument against your own position that you can — for example, the case that the other curve moved, or that prices in another part of the economy behave the opposite way. Argue it honestly; a weak objection you knock over earns no credit.
3. Your response to it (roughly 100 words). Say what you still hold, what changed, and what evidence, such as whether real output rose or fell, would settle the question.
4. One thing you would still check (one or two sentences). What would you look up or watch for to test your reading?

Effort. Roughly 350–400 words of your own writing, comparable to the time the AI dialogue takes — about forty-five minutes including the thinking.

What you submit. Post those four parts, under those four labels, as your Week 5 discussion post. That post is your entire submission; this route has no share link.

No replies to classmates are required.

Participation rubric

This discussion is worth 10 points. The same three criteria score both routes.
