Summary of "Desktop 2025 12 08 17 05 51 01"
Main ideas / lessons conveyed
Paper submission & revision rules
- One part of the assignment is the “final thing” for the current submission, but it is not heavily weighted, so it can be resubmitted in the later final assignment.
- A distinction is made between:
- Assignment 4A: the resubmittable part
- Assignment 4B: the individual part
Source quality & referencing standards
- A highlighted source about “Head Foundation” is not peer-reviewed (it is a nonprofit website). While it may be acceptable, the supervisor recommends more authoritative sources (e.g., the EU Commission or the US labor department), especially for the introduction.
- The paper needs more precision in wording and claims, especially regarding:
- what is meant by technology/skill requirements
- careful use of the term “prediction” in an econometric context
- clear definitions of unclear phrases such as “job predictions across the market.”
- Grammar and meaning must match what a reader would understand from the text.
- Citation formatting issues are emphasized:
- Use narrative citation style (e.g., “Ruben and Thomas describe…” instead of suggesting the paper “is active”).
- Ensure cited works appear in the reference list.
- DOI links: include them if available; otherwise, don’t force them.
- Follow correct formatting (e.g., italics for journal names, proper volume/issue style).
Structure and clarity in the introduction / literature review
- The introduction should:
- clearly answer the 5 W’s (who/where/when/what/why) as appropriate
- make the paper’s causal motivation prominent earlier (the word “causal” appears too late)
- explain the goal: remove/clean contamination from correlation and focus on causality using matching/propensity methods
- The literature review should be less generic and more narrative/organized:
- avoid phrases like “some people argue”
- start broad: how treatment effects are estimated generally; what is ATE
- then narrow: matching, and specifically propensity matching
- use the core papers you rely on to justify the review’s focus
How to frame research question, hypotheses, and sections
- The reviewer repeatedly asks for a clear hypothesis (not just expectations), with explicit wording, for example:
- “Hypothesis 1: job training correlates positively with real earnings after completion.”
- For subheadings:
- generally reduce excessive subsections to keep the narrative cohesive
- maintain the rule that each paragraph carries one idea
- in an 8-page document, keep to max two subsections
- avoid bullet points except when describing the algorithm
Content boundaries for the literature review
- Most sources should come from economics/statistics/development economics (and closely related fields).
- Medical or other-field citations are acceptable only peripherally (e.g., “matching is used in other fields such as medicine”), not in detailed depth that doesn’t support the economics goal.
Conceptual model / causal graph emphasis
- The narrative should make clear why the causal effect is biased:
- confounders influence both treatment choice and outcomes, contaminating correlation
- matching/propensity scores reduce those confounding paths so you can estimate the direct treatment → outcome effect
- For the causal diagram:
- simplify from complex diagrams into a clearer directed graph / triangle
- show that treatment and controls affect outcomes
- focus estimation on isolating the “red path” (treatment → outcome), avoiding other paths
Presentation guidance (slides and timing)
- Slide flow should resemble a standard paper/thesis outline:
- start broad → narrow to research question → specify what the study tests → data & methods → results structure
- Include an “eye-catcher” statistic early (example: “earn 35 more per hour” from job training), but connect it explicitly to the causality story.
- Mention matching in a sequence that clearly explains:
- why matching is needed (bias), not just that it is used
- Data slide guidance:
- use clear, correct naming (avoid vague phrases like “data set information”)
- include variables, measurement, number of observations, etc. (check details against earlier references)
- consider a table, but verify correctness
- Formula/equation slides:
- include enough to show how OLS and matching/estimators are applied
- remove overly long/standard graphics if redundant
Methodology comparison for the assignment
- The guidance becomes a consistent request:
- estimate treatment effect using OLS (baseline)
- compare it to propensity matching results
- also compare different matching algorithms (e.g., nearest neighbors vs kernel matching) and whether results differ or are similar
Operational questions raised by students
Common questions include:
- what algorithm selects nearest neighbors
- whether estimates differ across matching methods and what empirical literature says
- ensure each student speaks at least once, with:
- max three people speaking at once
- roughly three minutes per student
Methodology / instructions (bullet-point format)
Revision & writing instructions
For submission resubmission
- Confirm which assignment components can be resubmitted:
- Assignment 4A: highlighted “resubmitted/final part” (lower weight now; resubmission later)
- Assignment 4B: individual component (not the resubmittable part)
For introduction clarity
- Make the causal objective prominent earlier (not only in the last paragraph).
- Clearly explain:
- correlation vs causation
- the contamination problem (confounders affecting both treatment and outcomes)
- how matching/propensity methods address it
- Use precise grammar/meaning:
- explain skill requirements as the key concept (not “technology advances” itself)
- be cautious with the word “prediction” in econometrics
- define terms like “job predictions across the market”
For literature review structure
- Avoid generic transitions like “some people argue.”
- Use a narrowing structure:
- general treatment effects estimation → matching → propensity matching → papers using propensity matching relevant to your topic
- Ensure cited papers are placed/discussed appropriately (e.g., in the literature review vs the introduction).
For narrative/citation style
- Use narrative citation style:
- e.g., “Ruben and Thomas describe matching as a standard technique…”
- Avoid passive/incorrect phrasing that makes the paper seem “active.”
- If you cite a paper, it must appear in the reference list.
- Apply correct formatting:
- italicize journal names/fields as required
- Add DOI links when available; don’t invent DOIs.
For subsections & formatting
- Remove excessive subsections; keep paragraphs as one idea per paragraph.
- Allow at most two subsections if needed (8-page limit context).
- Avoid bullet points except for the algorithm.
For hypotheses
- Replace “expectations” with clearly stated hypotheses.
- Example:
- Hypothesis 1: job training correlates positively with real earnings after program completion.
- If comparing methods, you may add hypotheses such as:
- different matching methods yield different (or similar) estimated effects.
Presentation instructions
Timing & speaking
- Each student should speak at least once.
- Max three people speaking at once.
- Target about three minutes per student.
Slide sequence
- Use: motivation → research question → conceptual problem (bias) → method (OLS vs matching) → data overview → results framework.
Causal diagram
- Use a simplified directed graph:
- controls affect both treatment and outcome
- isolate the intended treatment → outcome path (the “red path”)
- avoid overly complex multi-step diagrams
Include comparators
- Show:
- OLS baseline comparison vs matching treatment effect
- comparisons across matching algorithms
Graphics
- Use fewer steps; keep diagrams readable and focused on the causal identification problem.
Data slide content
- Include:
- measurement of dependent/independent variables
- treatment definition
- sample size
- key variables
- Remove misnamed/duplicate slides if already covered elsewhere.
Method comparison instructions (what to run/compare)
Baseline
- Run OLS to estimate the treatment effect (simple regression baseline).
Matching
- Run propensity matching estimators (e.g., nearest neighbors, kernel matching—depending on the assignment).
Comparison goals
- Compare:
- OLS estimate vs matching estimate (bias reduction discussion)
- different matching algorithms’ estimated effects (whether they differ or are similar)
Explain matching logic in slides
- Clearly connect matching to the bias problem (confounder contamination).
