Pergunta feita ao analista

Among low-propensity voters, defined as those with a voting propensity of at most 0.68, what is the effect of receiving a get-out-the-vote phone call four weeks prior to the election on turnout?

Como o agente resolveu e como foi validado

Resumo passo a passo do que o agente executou, por que o caminho está correto e como cada verificação conferiu o resultado.

1. 1Preparação da base de dados
   panagopoulos_timing— The dataset consists of 25,000 registered voters in Rochester, New York, who were part of a randomized field experiment during the November 2005 municipal elections. Voters were randomly assigned to one of four groups: a phone reminder call scheduled for 4 weeks before Election Day, 2 weeks before, 3 days before, or a control group that received no call. The calls were nonpartisan get-out-the-vote reminders, delivered using standardized scripts. The unit of observation is the individual registered voter, and only those appearing on the official registration list were included. The main outcome is voter turnout in the 2005 election, while additional measures capture past voting history, party registration, demographics, and a predicted propensity to vote. The dataset also records whether each assigned reminder call was actually completed, allowing for comparison between group assignment and the reality of who was contacted.

   Derivação matemática e pressupostos

   coef.contacted_4weeks

   1. Com um instrumento e um regressor endógeno, o MQ2E é a razão entre o coeficiente de four_weeks na forma reduzida (vtr_gen05 sobre four_weeks e os controles) e no primeiro estágio (contacted_4weeks sobre four_weeks e os controles).β = ρ / π→ 0,00664393 (0.006643934362992571)
   2. Erro-padrão robusto à heterocedasticidade (HC1): a raiz da variância estimada do coeficiente.ep = √V_jj→ 0,0132133 (0.013213288842595752)
   3. Intervalo de 95% de confiança: a estimativa mais ou menos o valor crítico da distribuição t de Student com 24161 graus de liberdade vezes o erro-padrão.IC = β ± c · ep

   Pressupostos do estimador

   • the instruments affect the outcome only through the endogenous regressors (exclusion restriction)
   • the instruments are as good as randomly assigned given the controls
   • errors are independent across observations; their variance may differ
