In recent years, the three countries in North America (Canada, the United States and Mexico) and the three in the Northern Triangle of Central America (NTCA: Guatemala, El Salvador and Honduras) have experienced large human mobility within the region. Traditionally dominated by South-North migration, with the US and Canada as the main destinations, this migration system is now more complex as it includes new flows, places of origin, and destinations. This study analyzes socioeconomic and demographic dynamics in the sending and receiving countries alongside the migration policies in the three main destinations to help understand (a) to what extent flows between and within North America and the NTCA may continue in the short term and (b) what changes in migrants profiles can be expected in the future.

This paper measures the 2007–13 evolution of employment tax rates in the U.K. and the U.S. The U.S. changes are greater, in the direction of taxing a greater fraction of the value created by employment, and primarily achieved with new implicit tax rates. Even though both countries implemented a temporary “fiscal stimulus,” their tax rate dynamics were different: the U.S. stimulus increased rates, whereas the U.K. stimulus reduced them. The U.K. later increased the tax on employment during its “austerity” period. Tax rate measurements are a first ingredient for cross-country comparisons of labor markets during and after the financial crisis.

Finding cybernorms that are acceptable to the United States and China, which have different ideologies and practices as well as enormous interests at stake, is challenging. This article identifies these developments in China - the new Guiding Cases System as well as foreign and domestic developments regarding facilitating everyone’s access to cyberspace - and discusses how they, together with the Shanghai Cooperation Organization’s growing significance in the international arena, call for more strategic thinking among US policymakers so that the United States can seize the new opportunities to engage meaningfully with China in establishing international norms for cyberspace.

Public policy issues involving a complex mix of problems, exemplified today by climate change and the threat of nuclear war, require governance by institutions whose mandates and cultures embrace technological expertise as well as diplomatic and military skills. This paper is a case study of how such an institution operated during the Kennedy Administration to deal with the growing threat of radioactive debris in the environment and the threat of nuclear proliferation, and also put US-Soviet relations on a new trajectory. The 1963 Limited Test Ban Treaty might not have been concluded during the Kennedy Administration had the US Arms Control and Disarmament Agency not been established in 1961.
