Law-of-one-price violations, rather than anomalies measured against a pricing model, do the arguing in this GB792 Unit 1 board post on the joint hypothesis problem. Searches like "gb 792 unit 1 assignment example", "gb792 unit 1 sample" and "gb792 unit 1 example" land here.
What a finished GB792 Unit 1 discussion board post looks like
An initial post of roughly 430 words, four paragraphs long, sits above two replies. Paragraph one states the prompt's question and concedes the obstacle at once: a pattern in returns rejects efficiency only jointly with the benchmark used to call it abnormal, a point Fama made in 1970 and restated in 1991. Paragraph two sets out two cases that require no benchmark. Royal Dutch and Shell held fixed claims on one pool of cash flows, split 60 to 40 under a 1907 agreement, yet their share prices drifted far from that ratio for years. In March 2000, Palm traded above the market value of 3Com, which still owned most of it. The third paragraph asks why such gaps lasted, and the fourth states what the two cases do and do not establish.
How a GB792 Unit 1 example is structured
Obstacle, escape, complication, verdict: the order follows the argument's logic. Conceding the joint hypothesis first matters, because a post citing the size or value effect as proof of inefficiency has handed any risk theorist an easy reply. Both cases are chosen for one property only, that nobody needs an asset pricing model to see the mispricing, so the second paragraph spends its words on the mechanics of each claim rather than on the dollar gaps. The complication comes from Shleifer and Vishny's 1997 account of limits to arbitrage: short positions in Palm were scarce and costly to establish, and a convergence trade in the twin shares could lose money for years before it paid. The verdict paragraph separates a mispriced security from a profitable opportunity, and the replies press classmates on which of the two their own example shows.
Why a risk story always fits
An abnormal return is defined against a benchmark. If the benchmark omits a priced risk, the anomaly may be that risk, so pattern-based tests never reject efficiency alone.
Twin shares on fixed terms
Royal Dutch and Shell divided combined cash flows 60 to 40 by agreement. Share prices wandering away from that ratio need no model before anyone calls them mispriced.
A parent worth less than its stake
After Palm's March 2000 offering, the market valued Palm above 3Com, which still held most of its shares. The rest of 3Com was implicitly priced below zero.
Gaps that arbitrage left open
Borrowing Palm shares to sell short was scarce and expensive, and twin-share convergence could take years. Capital-constrained arbitrageurs, on Shleifer and Vishny's account, let such gaps persist.
Replies that ask which claim
Replies put one question to each classmate: whether their example shows prices wrong or profits available. Most anomalies, the post suggests, cannot show the first without assuming a model.
Where marks go in GB792 Unit 1
Citing the value or momentum premium as settled proof against efficiency is the error this prompt is typically written to expose, and a post built on it has no defense once a classmate names the joint hypothesis. Weaker posts state the joint hypothesis correctly and then ignore it two sentences later. Confusing mispricing with profit is the subtler slip: showing that Palm was overvalued says nothing yet about whether anyone could have earned money correcting it, and graders reading doctoral boards watch for that leap. Mechanics draw specific comment, such as reversing the 60 to 40 split or describing 3Com's stake as already distributed to its shareholders. Praise in a reply, without asking which claim an example supports, earns little, and posts running far past a section's word limit give up a little more.

GB792 Unit 1 questions, answered
Why not argue from a well-known anomaly like momentum?
Because a momentum premium rejects efficiency only if the benchmark model is correct, and a defender can always propose a missing risk factor. That does not make anomalies useless; it makes them weaker evidence for this particular question. Your post can still discuss them, provided it states what model they are measured against and why that model deserves trust.
Is the Palm and 3Com episode too old to cite?
Its age is an advantage here. The episode is thoroughly documented, Lamont and Thaler analyzed it in the Journal of Political Economy in 2003, and nothing about the logic has changed since. Where a section asks for recent evidence, dual-listed shares and closed-end fund discounts offer comparable cases, and the same reasoning about benchmarks and short-sale costs carries across.
Does the post have to take a side on efficiency?
It takes a narrow one. The sample concludes that law-of-one-price violations show prices can stay wrong for long periods, and it declines to call markets inefficient in any broader sense, since neither case offered a riskless profit to most investors. Many doctoral boards reward that kind of bounded claim over a sweeping verdict on markets as a whole.
