Hello there,

I am instrumenting my governance variable with politics variables. However my code does not save the first stage results.
Code:
ivreg2 risk4_w (governance_pillar_score = president congress govenor) company_size_w earnings_smoothing_2_w leverage_w dividend_ratio_w research_development_ratio_w sales_growth_w tangability_ratio_w turnover_rate_w i.sic_2, partial (company_size_w earnings_smoothing_2_w leverage_w dividend_ratio_w research_development_ratio_w sales_growth_w tangability_ratio_w turnover_rate_w i.sic_2) endog(governance_pillar_score) cluster(company_code) first savefirst sfirst
est store _ivreg2_risk4_w
est restore _ivreg2_governance_pillar_score
outreg2 using "IV-Regression", replace word tstat cttop(first)
est restore _ivreg2_risk4_w
outreg2 using "IV-Regression", cttop(second) word tstat
The problem here is the line with est restore _ivreg2_governance_pillar_score

Code:
. est restore _ivreg2_governance_pillar_score
estimation result _ivreg2_governance_pillar_score not found
Can somebody help me with that?
