A “Nuclear Umbrella” for Ukraine? Precedents and Possibilities for Postwar European Security

| Winter 2023/24

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war.

The Peril of Peaking Powers: Economic Slowdowns and Implications for China’s Next Decade

| Summer 2023

Peaking great powers facing a slowdown in growth are likely to try to violently shake up the world. These findings amend classic theories of great power conflict. They help explain some of the most consequential geopolitical events in modern history. And they have ominous implications for contemporary Chinese foreign policy.

Strategic Substitution: China’s Search for Coercive Leverage in the Information Age

| Summer 2022

After the mistaken U.S. bombing of the Chinese Embassy in Belgrade in 1999, China turned to information-age weapons to create a risk of escalation to nuclear war with the United States. This shift helps compensate for its conventional military inferiority.

Policy Spillovers, Technological Lock-In, and Efficiency Gains from Regional Pollution Taxes in the U.S.

| December 2022

We used the US-TIMES energy-system model in conjunction with integrated assessment models for air pollution (AP3, EASIUR, InMAP) to estimate the consequences of local air pollutant (LAP) and carbon dioxide (CO2) policy on technology-choice, energy-system costs, emissions, and pollution damages in the United States. We report substantial policy spillover: Both LAP and CO2 taxes cause similar levels of decarbonization. Under LAP taxes, decarbonization was a result of an increase in natural gas generation and a near-complete phaseout of coal generation in the electric sector. Under a CO2 tax, the majority of simulated decarbonization was a result of increased electric generation from wind and solar. We also found that the timing of the CO2 and LAP taxes was important. When we simulated a LAP tax beginning in 2015 and waited until 2025 to introduce a CO2 tax, the electric sector was locked into higher levels of natural gas generation and cumulative 2010–2035 energy system CO2 emissions were 8.8 billion tons higher than when the taxes were implemented simultaneously. A scenario taxing CO2 and LAPs simultaneously beginning in 2015 produced the highest net benefits, as opposed to scenarios that target either CO2 or LAPs, or scenarios that delayed either LAP or CO2 taxes until 2025. Lastly, we found that net benefits compared to business as usual are higher under a regional versus a national LAP-tax regime, but that efficiency gains under the regional tax are not substantially higher than those under the national LAP-tax policy.

Negative Security Assurances After Russia’s Invasion of Ukraine

| July 07, 2022

On February 24, the international community took a catastrophic blow. Already battered by two years of the COVID-19 pandemic and deteriorating interstate relations, it stood in horror as Russian forces unleashed an unprovoked war on a neighboring country. Russia’s decision to invade Ukraine and reject Ukraine’s very existence as a separate state is ominous and highly momentous for the future of the world order.

Defending the United States: Revisiting National Missile Defense against North Korea

| Winter 2021/22

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

Cologne Sanitizer, Boxed Wine and Bidets: How People in 68 Countries Are Coping With Coronavirus

| Mar. 22, 2020

As the novel coronavirus continues spreading, the whole world is preparing for the onslaught in similar ways—social distancing, working from home, panic buying at grocery stores. But people in different countries are also weathering this crisis in different ways, finding, for example, different products to hoard, different ways to pass the time, different people to blame and even different things to worry about.

Policy Evolution Under the Clean Air Act

| Fall 2019

The 1970 Clean Air Act established the basic architecture of the U.S. air pollution control system: It was the first environmental law to give the federal government a serious regulatory role, and it became a model for many subsequent environmental laws in the United States and abroad. In this article, the authors describe the evolution of air pollution control policy under this legislation with particular attention to the types of policy instruments used.

Dangerous Confidence? Chinese Views on Nuclear Escalation

    Authors:
  • Fiona S. Cunningham
  • M. Taylor Fravel
| Fall 2019

China and the United States hold opposing beliefs about whether nuclear war can be avoided in a potential crisis or armed conflict. Taken together, these opposing beliefs increase the risk of nuclear escalation and can lead to greater crisis instability.
