Marketing Science Academic Writing Skill

Skill by ara.so — Marketing Skills collection.

A comprehensive skill for AI coding agents to guide researchers through the complete pipeline of writing marketing science academic papers — from topic positioning and consumer utility modeling through identification design, structural estimation, counterfactual simulations, and full manuscript assembly.

Covers 8 flagship marketing journals: Marketing Science, JMR, JM, JCR (UTD-24 tier) and JAMS, IJRM, QME, Marketing Letters.

What This Skill Enables

This skill teaches AI agents to help researchers with:

• Topic Positioning: Gap analysis, journal selection, contribution framing
• Consumer Utility Modeling: Micro-founded demand systems (logit, nested logit, random coefficients)
• Identification Strategy: DID, RDD, IV, structural identification for causal inference
• Estimation Methods: BLP, GMM, MLE, Bayesian estimation workflows
• Counterfactual Simulations: Merger analysis, policy simulations, welfare calculations
• Experimental Design: Field experiments, conjoint analysis, A/B testing
• Full Draft Assembly: LaTeX manuscript generation with INFORMS formatting

The skill is domain-specific for marketing journals, encoding conventions that generic academic writing skills don't cover (e.g., structural model presentation, identification justification, counterfactual design, reviewer expectations).

Usage Patterns

Pattern 1: Full Pipeline Mode

User says: "Take me through the full marketing science pipeline for a paper on dynamic pricing in ride-sharing markets."

Agent workflow:

# Stage 1: Topic Positioning
# Read: references/journal-characteristics.md
# Output: Gap table, recommend Marketing Science or QME
# Ask user: "Confirm target journal: Marketing Science?"

# Stage 2: Consumer Utility Model
# Read: references/modeling-conventions.md
# Design: Random coefficients logit with time-varying price coefficients
# Output: §3 Model section draft with notation table

# Stage 3: Identification
# Read: references/identification-guide.md
# Design: IV strategy using weather shocks + cost shifters
# Output: §4 Identification and Estimation section

# Stage 4: Counterfactuals
# Read: references/counterfactual-guide.md
# Design: Simulate merger, price cap, surge pricing ban
# Output: §5 Counterfactual Results section

# Stage 5: Assembly
# Read: examples/manuscript_template.tex
# Generate: Full LaTeX draft with all sections

Pattern 2: Stage-Specific Help

User says: "I have my structural model. Help me design the identification strategy."

Agent action:

1. Read references/identification-guide.md
2. Ask user for endogenous variables, available instruments
3. Propose identification strategy (e.g., BLP instruments + cost shifters)
4. Draft §4.1 Identification subsection

Pattern 3: Code Generation for Estimation

User says: "Generate Python code for BLP estimation with random coefficients."

Agent uses examples/blp_estimation_example.py:

    print(f"  σ_mpg   = {theta_hat[2]:.4f} (SE: {se[2]:.4f})")

Key points:

• Use environment variables for data paths: os.getenv('DATA_PATH')
• Contraction mapping to invert shares → mean utilities
• Two-step GMM with optimal weighting matrix
• BLP instruments: sum of rivals' characteristics + cost shifters

Pattern 4: Counterfactual Simulation

Troubleshooting

Issue: "Skill not activating"

Solution: Ensure the skill directory name matches the name field in YAML frontmatter (marketing-science-writing). Check your agent's skills path:

# OpenCode
cat ~/.config/opencode/opencode.json | grep skills

# Claude Code
ls ~/.claude/skills/

# Cursor
ls ~/.cursor/skills/

Issue: "Agent doesn't use references"

Solution: The agent should auto-load reference files when the skill activates. Explicitly mention the stage or topic:

"Read references/identification-guide.md and design an IV strategy for my pricing problem."

Issue: "BLP code fails with singular matrix error"

Cause: Poor starting values or weak instruments in gmm_objective.

Solution:

1. Check instrument strength (F-stat > 10)
2. Use better starting values: initial_sigma = [0.1, 0.1, 0.1] (closer to zero)
3. Add regularization to avoid numerical singularities:

# In contraction_mapping, add damping
delta_new = 0.7 * delta + 0.3 * (delta + np.log(observed_shares) - np.log(s_pred))

Issue: "Counterfactual equilibrium not converging"

Cause: Bertrand equilibrium solver stuck in non-convex region.

Solution:

1. Use adaptive damping: prices = alpha * prices + (1-alpha) * prices_new, where alpha decreases over iterations
2. Try multiple starting points: pre-merger prices, marginal costs, uniform markups

# Multi-start approach
best_prices = None
best_obj = np.inf
for start in [pre_prices, marginal_costs * 1.2, marginal_costs * 1.5]:
    try:
        prices = solve_bertrand_equilibrium(model, ownership, start)
        obj = compute_nash_objective(prices, model, ownership)
        if obj < best_obj:
            best_prices, best_obj = prices, obj
    except:
        continue

Issue: "Journal reviewers want more robustness checks"

Solution: The skill includes a checklist in references/reviewer-expectations.md. Common requests:

• Alternative specifications: Nested logit, probit, heterogeneous coefficients
• Instrument validity: Sargan-Hansen test, reduced-form F-stats
• Placebo tests: Falsification tests on unaffected outcomes
• Subsample analysis: By market size, time period, product category
• Alternative identification: Different IV sets, DID with alternative control groups

The skill guides the agent to pre-emptively draft these in §5.3 Robustness Checks.

Advanced: Custom Pipelines

You can extend the skill for non-standard workflows:

Custom: Add Meta-Analysis Section

Edit SKILL.md to add a Stage 2.5:

### Stage 2.5: Meta-Analysis of Prior Effects

**Goal**: Synthesize effect sizes from prior literature.

**Agent actions**:
- Search for papers reporting similar treatment effects
- Extract effect sizes and standard errors
- Run random-effects meta-analysis
- Output forest plot and summary estimate
- Use summary estimate as prior for Bayesian estimation

Then reference from examples/meta_analysis.R:

library(meta)

# Load extracted effect sizes
effects <- read.csv(Sys.getenv('META_DATA_PATH'))

# Random-effects meta-analysis
ma <- metagen(TE = effect_size, seTE = std_error, data = effects,
              studlab = study_name, sm = "MD")

# Forest plot
pdf(file.path(Sys.getenv('OUTPUT_DIR'), 'forest_plot.pdf'))
forest(ma, sortvar = TE, xlim = c(-2, 2), 
       xlab = "Standardized Effect Size")
dev.off()

# Use pooled estimate as Bayesian prior
prior_mean <- ma$TE.random
prior_se <- ma$seTE.random

Custom: Multi-Method Papers

For papers combining structural + reduced-form:

1. Run Stage 3 twice: once for IV (reduced-form), once for BLP (structural)
2. Cross-reference estimates: "The structural price elasticity of -2.3 is consistent with the IV estimate of -2.1 in Table 3."
3. Use reduced-form as validation of structural model assumptions

Real-World Example Workflow

Scenario: You're writing a paper on the effect of influencer marketing on consumer demand in the beauty industry.

Step 1: Topic positioning

You: "I'm studying how Instagram influencer endorsements affect demand for beauty products. Help me position this for a top marketing journal."

Agent (activates skill):
- Reads references/journal-characteristics.md
- Searches for related papers (influencer marketing, social media, beauty industry)
- Builds gap table:
  | Paper | Method | Gap |
  |-------|--------|-----|
  | Smith (2020, JMR) | Survey experiment | Doesn't measure actual sales |
  | Jones (2021, MS) | Structural model of fashion | Different product category |
  | ...
- Recommends: "Marketing Science (structural model + counterfactuals) or JMR (field experiment + causal ID)"
- You choose: Marketing Science

Step 2: Consumer utility model

You: "Design the consumer utility model."

Agent:
- Reads references/modeling-conventions.md
- Proposes random coefficients logit:
  u_ijt = α_i · price_jt + β_1 · quality_jt + β_2 · influencer_endorsement_jt + ξ_jt + ε_ijt
  where α_i ~ N(α̅, σ_α²), heterogeneous price sensitivity
- Derives choice probabilities via simulation
- Specifies supply side: Bertrand pricing with marginal cost = production cost + influencer payment
- Outputs §3 Model section (15 pages with derivations)

Step 3: Identification

You: "I have data on influencer payments and Instagram follower counts. Design the identification strategy."

Agent:
- Reads references/identification-guide.md
- Proposes instruments:
  1. Excluded IV: lagged follower counts (affects endorsement but not demand directly)
  2. Cost shifter: platform algorithm changes (affects influencer payment but not ξ_jt)
- Drafts §4.1 Identification:
  - Discusses endogeneity of influencer_endorsement (brands select influencers based on unobserved ξ)
  - Justifies exogeneity of instruments (lagged followers determined before campaign)
  - First-stage F-statistic calculation

Step 4: Estimation code

You: "Generate the BLP estimation code."

Agent:
- Uses examples/blp_estimation_example.py as template
- Customizes for your model (adds influencer_endorsement variable)
- Outputs 200-line Python script with:
  - Data loading from $DATA_PATH
  - Contraction mapping with damping
  - GMM objective with your instruments
  - Two-step estimation
  - Standard errors via bootstrap

Step 5: Counterfactuals

You: "Design counterfactual: what if influencer payments were banned?"

Agent:
- Reads references/counterfactual-guide.md
- Designs simulation:
  1. Set influencer_endorsement = 0 for all products
  2. Resolve Bertrand equilibrium (firms optimize only price, not influencer budget)
  3. Compute welfare change:
     - Consumer surplus: higher (lower prices due to less spending on influencers)
     - Producer profit: lower (less differentiation)
     - Total welfare: ambiguous (depends on influencer effectiveness β_2)
- Outputs §6 Counterfactual Analysis with 3 tables

Step 6: Full draft assembly

You: "Write the full paper."

Agent:
- Reads examples/manuscript_template.tex
- Assembles:
  - §1 Introduction (motivation: $X billion influencer market, policy debates)
  - §2 Literature (gap table from Stage 1)
  - §3 Model (from Stage 2)
  - §4 Identification & Estimation (from Stage 3)
  - §5 Data (you provide descriptive stats, agent formats tables)
  - §6 Results (parameter estimates + model fit from Stage 3)
  - §7 Counterfactual (from Stage 5)
  - §8 Managerial Implications (reads references/marketing-implications.md)
  - §9 Conclusion
- Outputs: manuscript.tex (50 pages), compiles to PDF
