This paper investigates robust information transmission between a sender and a receiver in the Crawford and Sobel (1982) model. We characterize behavior that remains equilibrium behavior independently of the form of a small communication cost. Under standard conditions, we find that an...

The external validity of experimental results is essential in the social sciences. Existing methods estimate causal effects in a target population, called the target population average treatment effect (T-PATE). However, these methods are sometimes difficult to implement either because it is...

Researchers in the social sciences make extensive use of linear regression models in which the dependent variable is continuous-valued while the explanatory variables are a combination of continuous-valued regressors and dummy variables. The dummies partition the sample into groups, some of...

The well known Jarque-Bera (JB) test for normality uses the sample mean and sample standard deviation for estimating the population mean and population standard deviation. Instead of the sample standard deviation, Gel and Gastwirth (2008) proposed to use a robust scale estimator, known as the...

In this paper, a scaled independent component analysis (sICA) method is proposed for finding potential factors with more predictive power. The core idea is to improve the predictive effect of the model by giving more weight to those variables with stronger predictive power before estimating the...

For the panel data case where cross-sectional units are nested within higher-level groups, and there are many such groups, we propose a test that allows one to determine whether controlling for fixed effects at the more aggregate level is sufficient. The alternative is that one should allow for...

We extend the popular bias-based test of Stock and Yogo (2005) for instrument strength in linear instrumental variables regressions with multiple endogenous regressors to be robust to heteroskedasticity and autocorrelation. Equivalently, we extend the robust test of Montiel Olea and Pflueger...

This paper derives a novel representation of the exponential discounting model that allows me to set identify the discount factor while accounting for ostensible deviations from optimal behavior. I interpret these deviations as a by-product of measurement error. My approach uses a revealed...
