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...

Hospitals operate in markets with varied demographic, competitive, and ownership characteristics, yet research on ownership tends to examine hospitals in isolation. Here we examine three hospital ownership types - nonprofit, for-profit, and government - and their spillover effects. We estimate...

This presentation updates Nichols and Schaffer's 2007 UKSUG talk on clustered standard errors. Although cluster-robust standard errors are now recognized as essential in a panel data context, official Stata only supports clusters that are nested within panels. This rules out the possibility of...

Several options for estimation and prediction in regressions using nonnegative skewed dependent variables are compared. Often, Poisson regression outperforms competitors, even when its assumptions are violated and the correct model is one that justifies a competitor.

This article reviews An Introduction to Modern Econometrics Using Stata by Christopher F. Baum.

Problems with inferring causal relationships from nonexperimental data are briefly reviewed, and four broad classes of methods designed to allow estimation of and inference about causal parameters are described: panel regression, matching or reweighting, instrumental variables, and regression...

There has been a renewed interest in recent years in income inequality, economic mobility, and income volatility. I define an aggregate measure of income risk as half the squared coefficient of variation of incomes measured over both people and time, which can be decomposed into an inequality...
