But the IV chapter was better in terms of the details whereas RDD chapter isn't as heavy on those details. In my view, the emphasis on thinking about parameters of interest and identification before discussing technical matters is a huge improvement on traditional teaching approaches.

Here we address the questions of whether the quality and the credibility of empirical work have increased since Leamer’s pessimistic assessment. Experiments can also be used as benchmarks for framing one’s thinking - as an econometrician, consider what experiment you would like to run, then try to mimic it with available statistics as best as possible.

The winds of change have blown most strongly in applied microeconomics, but econometrics has been left far behind.

Mastering 'Metrics does a pretty good job of covering the intuition (and some of the math) behind random assignment, regression, instrumental variables, regression discontinuity designs, and difference in differences. This section helps the reader better appreciate the critical process of properly formulating tests before commencing analysis. Leamer was not alone; Hendry (1980), Sims (1980), and others writing at about the same time were similarly disparaging of empirical practice.

By contrast, Hill, Griffiths, and Lim (2011) introduce instrumental variable regression in an intimidating-sounding chapter on ‘Random Regressors and Moment-Based Estimation’. Teasing out these divergences from trends is a critical skill that requires the econometrician to delineate changes in data over time. Angrist and Pischke use case examples to focus on five core econometric topics: random assignments, regression, instrumental variables, regression discontinuity, and differences in differences.

ust ust over a quarter century ago, Edward Leamer (1983) reflected on the state of empirical work in economics.

Our regression application — estimating the effects of private college attendance on later earnings — shows the power of regression to turn night into day when it comes to causal conclusions.Modern econometrics is more than just a set of statistical tools--causal inference in the social sciences requires a careful, inquisitive mindset. There's nothing wrong with aiming econometrics at data scientists, in fact I think there is a lot that they can and should learn from each other. The ascendance of the five core econometric tools – experiments, matching and regression methods, instrumental variables, differences-in-differences and regression discontinuity designs – marks a paradigm shift in empirical economics.
