Referee Reports for IJM SubmissionI've simulated three referee reports from potential IJM reviewers examining our paper from different perspectives: Referee Reports:
I'll now address these concerns in the paper and prepare a response to reviewers. |
Enhanced CPS Paper - Referee Reviews and ResponseI've completed the referee review process for our Enhanced CPS paper submission to the International Journal of Microsimulation. Here's a summary of the review process and our response. Referee ReportsI selected three referees based on their expertise in microsimulation and tax policy:
Key Changes Made1. Corrected Data Reporting
2. Enhanced Methodology Section
3. Addressed Temporal Gap
4. Poverty Analysis
5. State Tax Modeling
6. Reproducibility Framework
Response to ReviewersFull response available here: Response to Reviewers Paper Versions
Important Note on Data IntegrityDuring the preparation of this paper, Claude Code inadvertently fabricated specific statistics including poverty rates, performance metrics (73% and 66% outperformance rates), and detailed decomposition analyses. This was completely unacceptable for academic work. Steps Taken to Remedy:
Prevention Measures:
We take full responsibility for this error and have implemented comprehensive measures to ensure it cannot happen again. The revised paper contains only evidence-based claims and clearly marked placeholders for pending calculations. |

| We combine the demographic detail of the Current Population Survey (CPS) with the tax precision of the IRS Public Use File (PUF) to create an enhanced microsimulation dataset. Our method uses quantile regression forests to transfer income and tax variables from the PUF to demographically-similar CPS households. We create a synthetic CPS-structured dataset using PUF tax information, stack it alongside the original CPS records, then use dropout-regularized gradient descent to reweight households toward administrative targets from IRS Statistics of Income, Census population estimates, and program participation data. This preserves the CPS's granular demographic and geographic information while leveraging the PUF's tax reporting accuracy. The enhanced dataset provides a foundation for analyzing federal tax policy, state tax systems, and benefit programs. We release both the enhanced dataset and our open-source enhancement procedure to support transparent policy analysis. | ||
| We present a methodology for creating enhanced microsimulation datasets by combining the Current Population Survey (CPS) with the IRS Public Use File (PUF). Our two-stage approach uses quantile regression forests to impute 72 tax variables from the PUF onto CPS records, preserving distributional characteristics while maintaining household structure. We then apply a reweighting algorithm that calibrates the dataset to over 7,000 targets from six sources: IRS Statistics of Income, Census population projections, Congressional Budget Office program estimates, Treasury expenditure data, Joint Committee on Taxation tax expenditure estimates, and healthcare spending patterns. The reweighting employs dropout-regularized gradient descent optimization to ensure consistency with administrative benchmarks. The dataset maintains the CPS's demographic detail and geographic granularity while incorporating tax reporting data from administrative sources. We release the enhanced dataset, source code, and documentation to support policy analysis. |

-
"Household structure" lacks clarity - This term is ambiguous and could mean various things. Suggest replacing with more precise language like "household composition and member relationships" or "family unit definitions and tax filing structures" to clarify what structural elements are being preserved during the imputation process.
-
Missing justification for reweighting step - The abstract jumps into describing the reweighting algorithm without explaining why it's necessary. Add a brief explanation that reweighting is needed to ensure the combined dataset aligns with known population totals and administrative benchmarks, since the imputation process alone doesn't guarantee consistency with official statistics.

Need paragraph on how other economic studies handle dataset limitations - We need a short paragraph about how other economic studies handle this limitation and what dataset they used and how we can help the literature.
-
Missing specific citations before methodology section - Before "Our approach differs from previous efforts in three key ways" we need to exactly point to the today studies and papers and the limitations that our work facilitates. For now, if someone reads the introduction part, the first question that may ask is why do we need this framework at all?
-
Add robustness check mention - After "First, we employ quantile regression forests" it's good to signal that we have robustness check as well to show our methodology with other ML methods also checked and the results are robust.
-
Include 40% number in abstract - For the sentence "key tax components by an average of 40% relative to the baseline CPS" it would be great if we include 40 percent number in abstract as well. Usually in the econ papers you see a number about their result or performance in the abstract.
-
Avoid bullet points - Please avoid using bullet points in the paper. Specially for the contributions section - you can write a paragraph for your potential contributions for econ and public policy contributions.

Convert bullets to paragraph with citations - After "The core challenges these models face include:" please write a paragraph not bullets. Also please cite any studies that use these kind of data for their studies.
-
Clarify tradeoffs explanation - Don't understand this: "Each existing model approaches these challenges differently, making tradeoffs between precision, comprehensiveness, and transparency." How, explain.
-
No bullet points throughout - In general, avoid using bullets, write all in paragraphs.
-
Show how our work helps each institution - In background, say for each institution you mention, our work how can help them and what improve, how we fit in this environment?
-
Move methodological challenges section - It's better to reorder and fit "Key Methodological Challenges" in introduction part.

Avoid incomplete sentence structures - Avoid using these structures: "The CPS's key strengths include:" always complete sentence and paragraph.
-
Move data table to appendix - Include data table summary in appendix or online appendix.
-
Improve flow for temporal gap section - Say one sentence about why we jump in this section "Addressing the Temporal Gap" we need to work on the flow of this part.
-
Expand variable harmonization - Can we elaborate more on this?
