Spring 2016 - 60544 - PA397C - Advanced Empirical Methods for Policy Analysis
Statistical Modeling for Policy Analysis
Statistics is easy. Good statistics – the kind you’d be comfortable basing public policy on – takes a little more work. This class focuses on the intuition underlying statistical technique, the art of learning from others’ mistakes, and the practical challenges of estimating, trouble-shooting, comparing, and interpreting models using real data. Students will estimate statistical models and report on their results throughout the course; they will also compile data, estimate and fine-tune a model, and draw policy implications for a final paper and presentation on a policy issue of their choice.
Specific topics will include the following:
- The role of uncertainty and modeling in policy choice;
- The classic ordinary least squares (OLS) model;
- Specification issues, including omitted variable bias, heteroskedasticity and autocorrelation, variable selection, and functional form;
- Causality, endogeneity, and instrumental variables;
- Research design, including experiments and quasi-experiments; and
- Combining and incorporating results from previous studies.
We will also consider some of these (somewhat more advanced and specialized) subjects:
- Limited dependent variables, including Poisson, binary and multiple response, Tobit, and survival analysis;
- Time-series (ARIMA) and forecasting models;
- Multivariate time-series, the error-correction model, and cointegration;
- Panel data and hierarchical linear models;
- Matching, regression discontinuity, and interrupted time-series designs; and
- Robust alternatives to OLS.
