Stopping the Bomb: The Sources and Effectiveness of U.S. Nonproliferation Policy

Why has American nuclear proliferation policy varied over time, and what explains its success or failure? Nicholas L. Miller argues that the United States’s behavior is linked to policymakers’ belief in a “nuclear domino effect”—the idea that proliferation in one state will encourage proliferation in others. Employing mixed methods, Miller illustrates how major twentieth century proliferation events encouraged this belief, opened up space in the bureaucracy for those who held it, and refocused policymaker attention on proliferation more broadly, with the result that the United States more vigorously pursued policies aimed at suppressing nuclear weapons development by other countries. Miller also explores when and why military and economic sanctions succeeded in preventing proliferation. He proposes that what efficacy these tools had lay in their deterrent effect. When actually levied, sanctions were generally ineffective, since the states that chose to develop nuclear weapons often lacked the economic and military ties that would make them vulnerable to such measures. Miller concludes that sanctions tend to be effective only against states that underestimate their impact.

Atomic Assurance: The Alliance Politics of Nuclear Proliferation

How can the United States best design its security commitments to discourage nuclear proliferation by its allies? Too much assurance, and an ally might be tempted into adventurism; too little, and an ally that fears abandonment might try to develop its own nuclear capability. Alexander Lanoszka explores this dilemma through a series of case studies, including a comparative study of Japanese and West German nuclear behavior, as well as analyses of South Korea and a number of other states that have received U.S. security guarantees. He shows that “in-theater conventional military deployments” are the most effective way to reassure allies, but that these alliances are ultimately limited in their ability to prevent proliferation. Partly because allies often begin a nuclear weapons program after their received security guarantees have frayed significantly, and thus commit to proliferation while "recognizing and accepting the risks and costs involved," Lanoszka concludes that alliances are "useful for preventing nuclear proliferation-related behaviors among their members but less useful for stopping a program once it has started."

Rising Titans, Falling Giants: How Great Powers Exploit Power Shifts

Why do rising states choose to cooperate with, or prey on, a declining power? Joshua R. Itzkowitz Shifrinson's “predation theory” proposes that rising states care not only about the degree of power held by a declining state, but also about the usefulness of that state to the advancement of their own security goals. If, for instance, a rising state needs support against other great powers and a declining state is able and willing to provide that support, the rising state will try to cooperate with the declining state—especially if the declining state is too weak on its own to pose a threat. However, if the declining state is so weak (or intransigent) as to be useless to the rising state, the rising state will try to take advantage of it. To support this theory, Shifrinson uses a set of archival, often revisionist, case studies, including cases from the beginning and end of the Cold War. He finds that the United States and the USSR, both desperately in need of allies after World War II, each worked to win the support of the weakened United Kingdom. In contrast, during the fall of the USSR a few decades later, a newly peerless United States took full advantage of the collapsing Soviet Union to expand its power through Eastern Europe and beyond—a conclusion that contradicts existing literature asserting that the United States cooperated with its weakened rival.

Please Circulate: Applications for Graduate Student Workshop

The Tobin Project is now accepting applications for our 2019 Graduate Student Workshop. The workshop will be held in Cambridge, MA on September 25th-27th and focus on the history of American democracy. Graduate students from any discipline are welcome to apply, and we hope you will consider sharing these opportunities with any who might be interested.


Tobin Holds Second Meeting on When Democracy Breaks

On February 8th and 9th, the Tobin Project held a meeting as part of our ongoing project on When Democracy Breaks. Scholars presented and received feedback on drafts of papers exploring eleven different moments of democratic crisis. By investigating the factors that led to the erosion of important institutions, norms, and values in each case, we hope to build a better understanding of why democracies falter. We are incredibly excited by the focus and rigor of this work so far, and we look forward to working with contributors as they finalize their drafts.





































 


 Institutions of Democracy


Legislative Staff and Representation in Congress

Recent research suggests that elected officials consistently misunderstand their constituents’ opinions and respond unequally to their preferences. To help explain this phenomenon, Alexander Hertel-Fernandez, Matto Mildenberger, and Leah C. Stokes assess senior U.S. Congressional staffers’ perceptions of public opinion in their districts and states. Using an original survey, they asked staffers to characterize their constituents’ views on five policy areas: gun control, carbon pollution restrictions, repeal of the Affordable Care Act, infrastructure spending, and raising the minimum wage. They find that legislative aides tend to misperceive their constituents’ policy preferences on these issues and, in particular, to overestimate the degree of their conservatism. Using observational analyses and survey experiments, the authors identify two potential sources of these misperceptions: staffers’ interactions with conservative and corporate interest groups, and their “egocentric biases.” The authors argue that their findings demonstrate the need for increased scholarly attention to legislative staffers’ role in democratic policymaking.

 Government & Markets


Cross-Ideological Coordination by Private Interests: Evidence from Mortgage Market Regulation Under Dodd-Frank

How do special interest groups seeking to influence government regulations interact with one another? In this working paper, Sanford C. Gordon and Howard Rosenthal examine how the politics of rulemaking around financial markets informed the 2010 Dodd-Frank Act. While Dodd-Frank required banks to take a financial stake in the securities they created as a way of discouraging excessive risk-taking, some types of assets—such as “qualified residential mortgages”—were exempted from the requirement. Through an analysis of regulatory debates, Gordon and Rosenthal find that early versions of the law would have only exempted certain qualified mortgages, yet the final law eliminated the financial stake requirement for these types of mortgages altogether. They argue that the proposed regulation was weakened not simply as a result of maneuvering by large banks, but rather through the collective effort of a diverse coalition of homebuilders, mortgage brokers and insurers, and advocates for minority homeowners. Using text analysis tools, the authors find that the timing and content of these interest groups’ comments were coordinated, and hypothesize that this coalition formed out of a bargain between well-financed industry groups that funded lobbying campaigns and non-profit organizations that contributed ideological diversity to the effort. This hypothesis suggests the need for greater nuance in considering how interest groups come to influence regulatory outcomes.

The Biological Embedding of Early-Life Socioeconomic Status and Family Adversity in Children’s Genome-Wide DNA Methylation

What is the impact of inequality on our DNA? In this paper, Nicole R. Bush, Rachel D. Edgar, Mina Park, Julia L. MacIsaac, Lisa M. McEwen, Nancy E. Adler, Marilyn J. Essex, Michael S. Kobor, and W. Thomas Boyce study a diverse population of nine- to eleven-year-olds in San Francisco to determine the relationship between low childhood socioeconomic status and DNA methylation—the process through which methyl groups are added to DNA to determine which genes are expressed. Controlling for genetic ancestry and self-reported ethnic minority status, the authors find that income-per-dependent, parental education, and (to a lesser extent) family adversity are each correlated with “distinct DNA methylation associations.” These associations could contribute to health and developmental disparities later in life. The authors suggest that this finding could lead to new areas of study, including research on whether these associations are reversible or preventable and whether low childhood SES correlates with other genetic markers besides DNA.
