This paper presents the Economic Security Index (ESI), a new, more comprehensive measure of economic insecurity. By combining data from multiple surveys, we create an integrated measure of volatility in available household resources, accounting for fluctuations in income and out-of-pocket...

This overview of implementing quasi-experimental methods of estimating causal impacts (panel methods, matching estimators, instrumental variables, and regression discontinuity) emphasizes practical considerations and Stata-specific approaches. I pay particular attention to the regression...

In this presentation, I provide a brief overview of quasiexperimental methods of estimating causal impacts using Stata: panel data, matching and reweighting, instrumental variables, and regression discontinuity designs, emphasizing practical considerations. I pay particular attention to the...

This overview of implementing quasi-experimental methods of estimating causal impacts (panel methods, matching estimators, instrumental variables, and regression discontinuity) emphasizes practical considerations and Stata-specific approaches, with examples using real data and comparisons across...

I review existing literature on weak instruments (possibly with multiple endogenous variables), and the research in progress by Jim Stock and others. I demonstrate the use of tests for weak instruments, and present a new graphical technique for presenting coefficient estimates that allows for...

A brief introduction to estimating Generalized Method of Moments models in Stata, using the optimize() function in Mata, with applications to nonlinear IV models.

A brief survey of clustered errors, focusing on estimating cluster–robust standard errors: when and why to use the cluster option (nearly always in panel regressions), and implications. Additional topics may include using svyset to specify clustering, multidimensional clustering, clustering in...

Using panel data from the Survey of Income and Program Participation linked to Social Security Administration disability determination records we trace the pattern of household income and the sources of that income from 38 months prior to 39 months following application for Social Security...

The Social Security Disability Insurance (SSDI) system is designed to provide income security to workers in the event that health problems prevent them from working. In order to qualify for benefits, applicants must pass a medical screening that is intended to verify that the individual is truly...
