Abstract
Oneal and Barbieri & Peters offer divergent critiques of Gartzke & Li, who present a mathematical identity between competing operationalizations of dyadic interdependence, and show that the relationship one finds between conflict and commerce depends on how one constructs one’s dyadic indicator of trade. Oneal seems to accept the identity, but not some of its implications. Barbieri & Peters challenge the identity and offer contrasting results. Here, we show that Barbieri & Peters’s results are due to their model specification, which Gartzke & Li argue involves omitted variable bias.
