Unobserved spatial confounding variables are prevalent in environmental and ecological applications where the system under study is complex and the data are often observational. Instrumental variables (IVs) are a common way to address unobserved confounding; however, the efficacy of using IVs on spatial confounding is largely unknown. This paper explores the effectiveness of IVs in this situation – with particular attention paid to the spatial scale of the instrument. We show that, in case of… Expand

Confounding by unmeasured spatial variables has received some attention in the spatial statistics and causal inference literatures, but concepts and approaches have remained largely separated. InExpand

TLDR
These methods are extended to the spatiotemporal case where they compare and contrast the potential outcomes framework with Granger causality, and to geostatistical analyses involving spatial random fields of treatments and responses. Expand

TLDR
In an application on the association between black carbon particulate matter air pollution and birth weight, controlling for large-scale spatial variation appears to reduce bias from unmeasured confounders, while increasing uncertainty in the estimated pollution effect. Expand
Generalized propensity score approach to causal inference with spatial interference
Many spatial phenomena exhibit treatment interference where treatments at one location may affect the response at other locations. Because interference violates the stable unit treatment valueExpand
Structural Equation Models for Dealing With Spatial Confounding
ABSTRACT In regression analyses of spatially structured data, it is common practice to introduce spatially correlated random effects into the regression model to reduce or even avoid unobservedExpand
Adjusting for unmeasured spatial confounding with distance adjusted propensity score matching
TLDR
DAPSm provides a framework for augmenting a “standard” propensity score analysis with information on spatial proximity and provides a transparent and principled way to assess the relative trade‐offs of prioritizing observed confounding adjustment versus spatial proximity adjustment. Expand
Spatial interdependence and instrumental variable models
Abstract Instrumental variable (IV) methods are widely used to address endogeneity concerns. Yet, a specific kind of endogeneity – spatial interdependence – is regularly ignored. We show thatExpand

The spatial dynamic panel data (SDPD) model is a standard tool for analysing data with both spatial correlation and dynamic dependences among economic units. Conventional estimation methods rely onExpand

Addressing geographic confounding through spatial propensity scores: a study of racial disparities in diabetes
TLDR
The development of a spatial doubly robust propensity score estimator to reduce bias associated with geographic confounding, which occurs when measured or unmeasured confounding factors vary by geographic location, leads to imbalanced group comparisons. Expand
