(Don't) Walk This Way: The Econometrics of Crosswalks

Millimet, Daniel L. - 2024

units are not nested, a crosswalk specifying how the units from one data source are allocated to the units of the other is … attention of econometricians. Here, I show that use of an incorrect crosswalk induces measurement error that is necessarily … nonclassical and can be consequential. I discuss and illustrate the ramifications of using a flawed crosswalk, present two …

A comment on "Motivated Errors" by Exley and Kessler (2024)

Auer, Tobias; Ulasik, Maria; Holzmeister, Felix - 2024

This report evaluates the computational reproducibility and analytical robustness of Exley and Kessler's (2024) investigation into "motivated errors," which suggests that individuals may rationalize selfish behavior by attributing their errors to confusion. Using the original data and code, we...

COVID-19 severity: a new approach to quantifying global cases and deaths

Millimet, Daniel L.; Parmeter, Christopher F. - 2021

Accurate counts of cases and deaths are critical for devising an optimal pandemic response. Yet, as the COVID-19 pandemic has progressed, so too has the recognition that cases and deaths have been underreported, perhaps vastly so. Here, we present an econometric strategy to estimate the true...

A model of errors in BMI based on selfreported and measured anthropometrics with evidence from Brazilian data

Davillas, Apostolos; Oliveira, Victor Hugo de; Jones, … - 2022

The economics of obesity literature implicitly assumes that measured anthropometrics are error-free and they are often treated as a gold standard when compared to self-reported data. We use factor mixture models to analyse and characterize measurement error in both self-reported and measured...

An empirical total survey error decomposition using data combination

Meyer, Bruce D.; Mittag, Nikolaus - 2019

Survey error is known to be pervasive and to bias even simple, but important estimates of means, rates, and totals, such as poverty statistics and the unemployment rate. To summarize and analyze the extent, sources, and consequences of survey error, we define empirical counterparts of key...

Populism and polarization in social media without fake news : the vicious circle of biases, beliefs and network homophily?

Hakobyan, Zaruhi; Koulovatianos, Christos - 2020

We build a model of network dynamics with decision-making under incomplete information in order to understand the determinants of the observed gradual downgrading of expert opinion on complicated issues and the decreasing trust in science. We suggest a search and matching mechanism behind...
