Jones (1991) is taken down to the stability assumption that turns an accrual model into a measure of manipulation in this GB791 Unit 2 research article critique. Searches like "gb 791 unit 2 assignment example", "gb791 unit 2 sample" and "gb791 unit 2 example" land here.
What a finished GB791 Unit 2 research article critique looks like
Six pages in four parts under a full citation: Jones, J. J. (1991), Earnings management during import relief investigations, Journal of Accounting Research, 29(2). Part one restates the question and the incentive: firms in industries petitioning for protection benefit if their earnings look depressed during the investigation. Part two describes the design, firm-specific regressions of total accruals on the change in revenue and gross property, plant and equipment, each scaled by lagged assets and estimated over years before the investigation, with prediction errors in the investigation year read as discretionary accruals. Part three states the identifying assumption and tests it. Part four says what may be concluded beyond the sample, and closes by noting how the model became the field's standard instrument, with later corrections by Dechow, Sloan and Sweeney and by Kothari, Leone and Wasley.
How a GB791 Unit 2 example is structured
The critique follows the order a referee uses: question, design, identification, inference. The question is restated in one sentence with the incentive that makes the prediction directional. Design is described exactly enough that the estimation could be rebuilt, because the critique's objections depend on details like the scaling and the estimation window. The identifying assumption receives the longest part: nondiscretionary accruals follow revenue change and fixed assets in a stable firm-specific way, and nothing else in the investigation year moves accruals. Each threat is then tested against it: revenue itself can be managed, firms in declining industries produce negative accruals from performance alone, and a small sample limits power. The inference section separates what the evidence supports, income-decreasing accruals during investigations, from what it cannot, the magnitude of manipulation. Influence is discussed last, as consequence rather than proof of quality.
Question and incentive
Protection from imports depends partly on showing injury, so depressed earnings help a petition. The prediction runs in one direction, which is what gives the test its sharpness.
A regression rebuilt
Total accruals regressed on revenue change and gross fixed assets, scaled by lagged total assets, estimated firm by firm before the investigation year. The critique states each choice.
The assumption carrying the result
Normal accruals must relate to those drivers the same way in the investigation year as before it. Every inference about manipulation rests on that stability.
Three threats, each tested
Managed revenue, performance-driven accruals in distressed industries and limited statistical power each attack the assumption from a different side, and the critique weighs them separately.
What travels beyond the sample
Direction, yes, within a setting with a clear incentive. Magnitude and generality, less so. Later corrections to the model are read as responses to exactly these limits.
Where marks go in GB791 Unit 2
Critiques that summarize the article's findings, even accurately, without naming the assumption on which they rest are graded as summaries, and at doctoral level that is the defining failure. Identifying the assumption vaguely, calling it a limitation of the model, stops short: the critique has to say what must be stable, over what window and why an investigation year might disturb it. Threats listed without being connected to the assumption read as a generic methods checklist. Candidates who dismiss the paper because later work improved on it misread the genre, since a critique judges the design against its own question. Getting the model wrong, omitting the scaling or placing receivables in the original specification, draws precise comment. Missing full citations, and confusing statistical significance with economic magnitude, cost smaller amounts.

GB791 Unit 2 questions, answered
Why critique a paper from 1991 rather than a recent study?
Because the Jones model still sits inside a large share of earnings management research, so its assumption is inherited by work published this year. Critiquing the original shows where that inheritance comes from. If your section requires a recent article, the same four-part structure applies, and a recent paper using a Jones-type model makes an especially good candidate.
What is an identifying assumption, in plain terms?
It is the condition that must hold for a study's comparison to measure what the authors say it measures. In Jones (1991), prediction errors count as manipulation only if normal accruals behave in the investigation year as they did before. If something else changed accruals that year, the model would label ordinary business as earnings management. Every empirical design has at least one such condition.
Should the critique propose a better design?
Briefly, where it clarifies a threat. This sample notes that a performance-matched control, of the kind Kothari, Leone and Wasley later proposed, would address the distressed-industry problem. A full alternative design belongs in later units. The critique's main task is judging whether this design answers this question, not writing the paper the reviewer would have preferred.
