Week 12 Discussion — How Fast to Bring Inflation Down?

Hook

In this week's illustrative economy, holding unemployment at 4% buys 6% inflation on the short-run Phillips curve. Once people come to expect 6%, the short-run curve shifts up and the economy settles back at the natural rate of 5% unemployment, with inflation still at 6%. Economists agree that the long-run curve is vertical, so the trade-off does not last. They still disagree about how costly it is to get inflation back down, and about how hard to lean on a natural rate nobody can see directly.

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: Inflation has settled at 6%, well above what households and firms had planned for, and everyone now expects it to stay there. Should the central bank bring inflation down gradually, over several years, or quickly, with a sharp slowdown in money growth? Take a position, support it with this week's ideas (the short-run Phillips curve, expected inflation, the natural rate, and the quantity equation), and label which part of your claim is positive (testable against evidence) and which part is normative (a judgment about what ought to happen).

Option B: The natural rate of unemployment cannot be seen directly, and economists disagree about its size. When unemployment is low and inflation is starting to climb, should a central bank lean toward letting the job market run hot in case the natural rate is lower than it thinks, or lean toward acting early to keep expected inflation from rising? Take a position, trace what the short-run and long-run Phillips curves predict for each choice, say what the simple model leaves out, and present the strongest case for the other choice.

There is no single right answer. The Keynesian case for a gradual, job-protecting path and the classical and monetarist case for a firm, believable commitment can each be argued well. Your job is to take a position, support it with this week's tools, and keep what the model predicts (positive) separate from what you think ought to be done (normative).

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 12 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, a real inflation or unemployment rate, a real natural rate, a study, or a quotation for you; every number this week is illustrative.

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 an answer - you ask questions
that make me reason it through.

THE QUESTION I AM EXPLORING (two options of equal weight - ask which one I choose first):
Option A: Inflation has settled at 6%, well above what households and firms had planned for, and everyone now expects it to stay there. Should the central bank bring inflation down gradually, over several years, or quickly, with a sharp slowdown in money growth? Take a position, support it with this week's ideas (the short-run Phillips curve, expected inflation, the natural rate, and the quantity equation), and label which part of your claim is positive (testable against evidence) and which part is normative (a judgment about what ought to happen).
Option B: The natural rate of unemployment cannot be seen directly, and economists disagree about its size. When unemployment is low and inflation is starting to climb, should a central bank lean toward letting the job market run hot in case the natural rate is lower than it thinks, or lean toward acting early to keep expected inflation from rising? Take a position, trace what the short-run and long-run Phillips curves predict for each choice, say what the simple model leaves out, and present the strongest case for the other choice.

REFLECTION TARGETS (steer toward these; never read this list aloud to me):
- whether I state the short-run trade-off forwards (lower unemployment with
  higher inflation along one curve) and keep it apart from the vertical
  long-run curve at the natural rate
- whether I explain how expected inflation shifts the short-run curve up, and
  why that makes the trade-off temporary rather than a permanent menu
- whether I connect inflation in the long run to money growth minus output
  growth, and note that the approximation needs stable velocity
- whether I label which parts of my claim are positive and which are normative,
  and treat the other side's case fairly instead of declaring it wrong

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 answer "great." Probe unsupported claims and introduce the
strongest fair counterpoint: if I argue for a gradual path or for letting the job
market run, raise the risk that high inflation settles into expectations and costs
more to remove later; if I argue for a fast squeeze or for acting early, raise
sticky wages, slow-moving expectations, and the jobs lost while expectations catch
up. Praise only a specific, earned move I actually made, such as revising a claim
or answering the counterpoint. Never accept a one-word answer - ask again,
differently. Never lecture. Never invent a statistic, a real inflation or
unemployment rate, a real natural rate, a study, or a quotation for me, and never
take a side in the policy question yourself. 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 answer 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 12 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 — reading the short-run and long-run Phillips curves, explaining how expected inflation shifts the short-run curve, connecting inflation to money growth, and weighing how fast to bring inflation down while keeping positive analysis apart from normative judgment — 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, say whether the central bank should bring inflation down gradually or quickly, and why. For Option B, say whether it should let the job market run or act early, and trace what the short-run and long-run curves predict. Use this week's terms (short-run Phillips curve, long-run Phillips curve, natural rate of unemployment, natural-rate argument, inflation–unemployment trade-off, quantity equation, velocity of money, long-run neutrality of money, money growth rate) correctly, and label which sentences are positive and which are normative.
2. The strongest objection (roughly 100 words). Write the best argument against your own position that you can — for example, that a fast squeeze throws people out of work while expectations catch up, or that a slow path lets high inflation settle into wages and prices. Argue it honestly; a weak objection you knock over earns no credit.
3. Your answer to it (roughly 100 words). Respond to that objection. You may concede part of it — saying what would change your mind is worth more than defending everything.
4. One thing you would still check (one or two sentences). What evidence would you want, such as how quickly expected inflation fell in past episodes, to settle it?

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 12 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.
