Week 11 Discussion — Fine-Tune or Follow a Rule?

Hook

In this week's illustrative economy, a Fed bond purchase lowers the interest rate from 6% to 4%, investment rises by 40 billion dollars, and aggregate demand shifts right by 200 billion. On paper the chain runs in five quick lines. In a real economy it runs with inside and outside lags, and borrowers' expectations can weaken it, so economists who share the same chain still disagree about how often a central bank should pull the lever.

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: The economy has slipped into a recessionary gap: hiring has slowed and builders are idle. Should the central bank cut interest rates now and keep adjusting as new data arrive (fine-tuning), or should it follow a predictable policy rule announced in advance and resist reacting to each new report? Take a position, support it with this week's ideas (the transmission mechanism, the inside and outside lags, long and variable lags, and expectations), 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: Prices are climbing, and the central bank knows that a rate increase takes time to work. Should it raise rates now, based on where it expects the economy to be once the outside lag has passed, or should it wait until the data plainly show that the economy is overheating? Take a position, trace what the contractionary chain predicts link by link, say what the simple chain leaves out, and present the strongest case for the other choice.

There is no single right answer. The Keynesian case for active stabilization and the monetarist case built on long and variable lags 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 11 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 interest rate, a length for the lags, 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: The economy has slipped into a recessionary gap: hiring has slowed and builders are idle. Should the central bank cut interest rates now and keep adjusting as new data arrive (fine-tuning), or should it follow a predictable policy rule announced in advance and resist reacting to each new report? Take a position, support it with this week's ideas (the transmission mechanism, the inside and outside lags, long and variable lags, and expectations), 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: Prices are climbing, and the central bank knows that a rate increase takes time to work. Should it raise rates now, based on where it expects the economy to be once the outside lag has passed, or should it wait until the data plainly show that the economy is overheating? Take a position, trace what the contractionary chain predicts link by link, say what the simple chain 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 trace the policy through the five links in order (money supply,
  interest rate, investment, spending multiplier, aggregate demand) instead of
  jumping from a rate change straight to output
- whether I keep the spending multiplier 1 / (1 - MPC) in the output link and
  the money multiplier 1 / RR in the first link only
- whether I separate the inside lag (recognize and decide) from the outside lag
  (borrowing and spending respond), and take expectations into account
- 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 fine-tuning or acting early, raise long
and variable lags and the risk of a mistimed move; if I argue for a rule or for
waiting, raise idle workers, sticky prices, and the cost of a gap left open.
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 interest rate, a lag length, 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 11 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 — explaining how monetary policy travels through the transmission mechanism to aggregate demand, separating the inside lag from the outside lag, and weighing fine-tuning against a policy rule 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 fine-tune or follow a rule, and why. For Option B, say whether it should act early or wait, and trace the contractionary chain link by link. Use this week's terms (the transmission mechanism, interest-sensitive spending, expansionary monetary policy, contractionary monetary policy, inside lag, outside lag, fine-tuning, policy rule, long and variable lags) 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 long and variable lags can make an early move land at the wrong time, or that workers lose income every month a gap stays open. 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 long past rate changes took to reach home building, 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 11 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.
