The paper provides detailed guidance on selecting suitable collections of auxiliary outcomes and combining TMO with existing spatial standard errors. STATA code for implementing TMO is available here:

Very excited to share this new working paper, joint with @sdellavi, @guido_imbens, and Woojin Kim!

The Thresholding Multiple Outcomes method addresses spatial correlation in regressions by using information from additional outcomes to identify correlated locations, from @sdellavi, @guido_imbens, Woojin Kim, and @DRitzwoller https://t.co/lbCjyeiSYH

[David Ritzwoller @DRitzwoller]

Applying TMO to nine recent papers, we find significant impacts on estimated standard errors, with a median increase of 37% compared to the published estimates.

(2) Determine a threshold from these estimates; pairs exceeding this threshold are modeled as correlated.
(3) Compute standard errors by accounting only for correlations above the threshold.

[David Ritzwoller @DRitzwoller]

Our proposed method, Thresholding Multiple Outcomes (TMO), has three steps:
(1) Estimate pairwise correlations across locations using multiple outcomes.

We were thrilled to welcome students & faculty from @SpelmanCollege @Spelman_Econ @Morehouse for the 2nd annual Stanford-Spelman-Sloan Summer Institute last week. Big thank you to @Stanford, @SloanFoundation, & @SIEPR for making this possible. Here’s our amazing visit. [1/ 15]
