Sensitivity analyses characterizing the hypothetical unobserved conditions that can alter estimates and statistical inferences are increasingly being applied in the social and health sciences. One of the most ascendant techniques is Oster’s (2019) coefficient of proportionality, which builds...

The COVID-19 pandemic is forcing researchers, clinicians, and policymakers to accelerate the evaluation of treatments and vaccines. Critical to these evaluations is the ability to characterize the uncertainty of inferences in clear terms accessible to a broad set of stakeholders with varying...

In this chapter, we explicate two related techniques that help quantify the sensitivity of a given causal inference to potential omitted variables and/or other sources of unexplained heterogeneity. In particular, we describe the Impact Threshold of a Confounding Variable (ITCV) and the...

Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11...

We analyze the conditions under which a practice moves from rare and unacceptable to preponderant and legitimate through bottom-up, relational processes. To better understand the mechanisms and contingencies of such "emergence-based institutionalization," we combine computational agent-based...

Purpose: The purpose of this paper is twofold. First, the authors elaborate on why American businesses are often willing to advocate and deploy corporate political resources for or against specific governmental policies, but largely reluctant to engage in more general political process reform....
