Data Appendix: When Wars Travel Home — Geopolitical Shock Transmission and Entrepreneurial Formation in Pakistan

This dataset is the companion data appendix for "When Wars Travel Home: Geopolitical Shock Transmission and Entrepreneurial Formation in Pakistan," an empirical study examining whether the 2026 Iran–US war's economic shock transmitted into Pakistan's real economy, using only publicly verifiable secondary data. The workbook contains every source figure, derived statistic, and regression/robustness output underlying the article's tables and results, organized across the following sheets: README — overview and sheet index Brent_Crude — monthly Brent crude oil price data (IMF/FRED series POILBREUSDM, Jan 2024–Jun 2026) used for the interrupted time-series analysis ITS_Regression — full segmented regression output, including the main specification and six robustness checks (stationarity test, alternative break-date specification, placebo tests, HAC lag-length sensitivity, Bai-Perron multiple structural-break search, and independent cross-validation against R's peer-reviewed strucchange package) SECP_Registrations — Securities and Exchange Commission of Pakistan cumulative company-registration disclosures and the derivation of a monthly-equivalent series by differencing PKR_USD, Remittances, PSX_KSE100 — supplementary macroeconomic series (exchange rate, remittance inflows, equity index) Institutional_Timeline — dated regulatory and institutional events (EIU Democracy Index reclassifications, V-Dem Democracy Report, Pakistan's 27th Constitutional Amendment) No figure in the associated article is derived from any data not included in this workbook. All source series are transcribed exactly as published by the cited primary source (IMF, FRED, SECP, State Bank of Pakistan, EIU, V-Dem); derived columns are simple, independently verifiable arithmetic (differencing, percentage change, regression estimation) rather than estimation or interpolation.
