Research paper

I want to replicate the study “The effect of underwriter reputation and market sentiment on IPO underpricing: Evidence from Indonesia” (Ariyani & Gumanti, Modern Finance Journal, Vol 3 No 3, 2025) for the Gulf Cooperation Council, with an initial focus on Kuwait and Saudi Arabia. The job is end-to-end: gather the IPO data, run the identical econometric models, and produce publishable write-ups.

Scope
• Data: Source IPO prospectuses, offer prices, first-day closing prices, market indices and underwriter reputational measures from academic databases (I prefer peer-reviewed or institutional repositories). If additional sources are needed, recommend them and briefly justify their reliability.
• Methodology: Reproduce every test used in the original article—OLS regressions, robustness checks and diagnostic statistics—using the same variable definitions and transformations. Stata, R or EViews are all acceptable; include your annotated code.
• Writing: Deliver a concise abstract, full conclusions section and any explanation of deviations (if the GCC markets require slight model tweaks, document them). Tables and figures must mirror the original formatting so that results are directly comparable.

Deliverables
1. Clean, documented dataset for Kuwait and Saudi Arabia (Bahrain, Oman or Qatar can be added later).
2. Code scripts with comments.
3. Results tables and figures matching the Indonesian study’s structure.
4. 250-300 word abstract plus a conclusions section (≈1,000 words) highlighting similarities and differences between GCC findings.

Acceptance
• All variables match original definitions.
• Regression outputs reproduce key statistics (coefficients, t-stats, R², diagnostics).
• Writing is clear, cites data sources properly and is free of plagiarism.
