"When Foreign Countries Push The Button: Does the Nuclear Taboo Only Begin at the Water’s Edge?" Conditionally Accepted at International Security.
abstract
How strong are the constraints against nuclear use? Pessimistically, experimental studies find a majority of citizens in multiple major powers would approve of nuclear strikes by their own government. But what if the nuclear taboo only begins at the water’s edge when individuals evaluate the use of nuclear weapons by a foreign government? Many policymakers believe that the international reaction to nuclear use would be severe, especially among allies, but prior studies have not tested this assumption. This paper develops a theory of how variation in the identity of who conducts nuclear attacks conditions the constraints against nuclear use. It posits that support for nuclear use should be higher when conducted by domestic and allied governments compared to other foreign countries because it will be perceived as more ethical. A series of four survey experiments in the U.S. and India provide evidence for this theory. However, in contrast to the expectations of many policymakers, approval is not significantly less for allies or strategic partners than it is for domestic governments. Absolute support for nuclear attacks is also alarmingly high, even when it is foreign countries pushing the button. On balance, these findings are inconsistent with the existence of a nuclear taboo.
"To Compete or Retreat? The Global Diffusion of Reconnaissance Strike" (with Michael C. Horowitz).
abstract
The reconnaissance strike complex is a critical element of modern military power, and realist theories would have predicted rapid proliferation after its public debut in the first Gulf War. In fact, the reconnaissance strike complex has proliferated slowly. To explain this puzzle, we theorize that interstate security threats significantly impact proliferation, but not in the way traditionally presumed. Drawing on the economics literature and game theoretic insights from political science, we argue that the relationship should resemble an inverted-U. When states have rivals with moderate reconnaissance strike capabilities, they have security incentives to compete with them. However, when states face highly advanced adversaries, it becomes more difficult to escape or match their competition, making acquisition less appealing. While most prior research focuses on narrower aspects of the reconnaissance strike complex like missiles, we test our theory on a novel dataset tracking country-level acquisition of eight aspects of the reconnaissance strike complex from 1980-2017. We find strong support for our inverted-U argument, which contributes to the literature by helping explain both why some states continue to invest heavily in conventional capabilities despite an already-large lead over their adversaries and why other states instead opt to invest in alternative capabilities rather than balancing symmetrically.
"Think Globally, Act Locally: The Determinants of Local Policymakers' Support for Climate Policy" (with Sabrina B. Arias), Revise & Resubmit at Journal of Politics.
[Washington Post Article][Harvard Belfer Center Presentation]
abstract
Given the lack of sufficient progress at the national level to combat climate change, local environmental initiatives have taken on increased importance. However, relatively little research examines the policy preferences of local policymakers themselves, whether the design features of climate policies impact their preferences, and whether policymaker and public preferences are contradictory or congruent. To address these gaps in the literature, we conduct a conjoint experiment on over 500 local policymakers and pair this elite experiment with an identical replication conducted on the American public. Per our theoretical expectations, we find that a range of climate policy design elements have a significant impact on policymaker support, and elite preferences are largely congruent with public preferences. Although national polarization over climate change suggests hope for progress is far-fetched, our findings demonstrate the probability of policy adoption can be increased by strategic design and local climate initiatives can potentially gain the support of both policymakers and members of the public.
