Compelling and accessible, this Very Short Introduction challenges the perception of borders as passive lines on a map, revealing them instead to be integral forces in the economic, social, political, and environmental processes that shape our lives. Highlighting the historical development and continued relevance of borders, Alexander Diener and Joshua Hagen offer a powerful counterpoint to the idea of an imminent borderless world, underscoring the impact borders have on a range of issues, such as economic development, inter- and intra-state conflict, global terrorism, migration, nationalism, international law, environmental sustainability, and natural resource management. Diener and Hagen demonstrate how and why borders have been, are currently, and will undoubtedly remain hot topics across the social sciences and in the global headlines for years to come. This compact volume will appeal to a broad, interdisciplinary audience of scholars and students, including geographers, political scientists, anthropologists, sociologists, historians, international relations and law experts, as well as lay readers interested in understanding current events.

It is widely believed that globalization has proceeded to the point where international economic linkages are as strong as those within nations. Struck by research suggesting that this perception is dramatically mistaken, John Helliwell spent three years assessing the evidence. The results are reported in this book, the latest in Brookings' Integrating National Economies series. It provides the most systematic measurements yet available of the relative importance of global and national economic ties. The original finding, based on a gravity model of trade flows, was that 1988 trade linkages between Canadian provinces were twenty times as dense as those between Canadian provinces and U.S. states of similar size and distance. A much longer and more detailed body of data is used to expand and explain these findings. Data for trade within and among OECD and some developing countries are used to show that the Canadian-U.S. results are applicable to other countries. Helliwell then surveys and extends the evidence relating to price linkages, capital mobility, migration, and knowledge spillovers, finding in all cases very large border effects. The evidence offers a challenge to economists, policymakers, and citizens to explain why national economies have so much staying power, and to consider whether this is a good or bad thing. Helliwell argues that since large and small industrial economies have similar levels of income, there are likely to be diminishing returns from increases in globalization beyond levels sufficient to permit the ready exploitation of comparative advantages in trade, and relatively easy access to knowledge developed elsewhere.

Seeking to re-imagine the meaning and significance of the international border, Opening the Floodgates makes a case for eliminating the border as a legal construct that impedes the movement of people into this country. Open migration policies deserve fuller analysis, as evidenced by President Barack Obama’s pledge to make immigration reform a priority. Kevin R. Johnson offers an alternative vision of how U.S. borders might be reconfigured, grounded in moral, economic, and policy arguments for open borders. Importantly, liberalizing migration through an open borders policy would recognize that the enforcement of closed borders cannot stifle the strong, perhaps irresistible, economic, social, and political pressures that fuel international migration. Controversially, Johnson suggests that open borders are entirely consistent with efforts to prevent terrorism that have dominated immigration enforcement since the events of September 11, 2001. More liberal migration, he suggests, would allow for full attention to be paid to the true dangers to public safety and national security.

Do states have the right to prevent potential immigrants from crossing their borders, or should people have the freedom to migrate and settle wherever they wish? Christopher Heath Wellman and Phillip Cole develop and defend opposing answers to this timely and important question. Appealing to the right to freedom of association, Wellman contends that legitimate states have broad discretion to exclude potential immigrants, even those who desperately seek to enter. Against this, Cole argues that the commitment to the moral equality of all human beings - which legitimate states can be expected to hold - means national borders must be open: equal respect requires equal access, both to territory and membership; and that the idea of open borders is less radical than it seems when we consider how many territorial and community boundaries have this open nature. In addition to engaging with each other's arguments, Wellman and Cole address a range of central questions and prominent positions on this topic. The authors therefore provide a critical overview of the major contributions to the ethics of migration, as well as developing original, provocative positions of their own.

In Border and Rule, one of North America’s foremost thinkers and immigrant rights organizers delivers an unflinching examination of migration as a pillar of global governance and gendered racial class formation. Harsha Walia disrupts easy explanations for the migrant and refugee crises, instead showing them to be the inevitable outcomes of the conquest, capitalist globalization, and climate change that are generating mass dispossession worldwide. Border and Rule explores a number of seemingly disparate global geographies with shared logics of border rule that displace, immobilize, criminalize, exploit, and expel migrants and refugees. With her keen ability to connect the dots, Walia demonstrates how borders divide the international working class and consolidate imperial, capitalist, and racist nationalist rule. Ambitious in scope and internationalist in orientation, Border and Rule breaks through American exceptionalist and liberal responses to the migration crisis and cogently maps the lucrative connections between state violence, capitalism, and right-wing nationalism around the world. Illuminating the brutal mechanics of state formation, Walia exposes US border policy as a product of violent territorial expansion, settler-colonialism, enslavement, and gendered racial ideology. Further, she compellingly details how Fortress Europe and White Australia are using immigration diplomacy and externalized borders to maintain a colonial present, how temporary labor migration in the Arab Gulf states and Canada is central to citizenship regulation and labor control, and how racial violence is escalating deadly nationalism in the US, Israel, India, the Philippines, Brazil, and across Europe, while producing a disaster of statelessness for millions elsewhere. A must-read in these difficult times of war, inequality, climate change, and global health crisis, Border and Rule is a clarion call for revolution. The book includes a foreword from renowned scholar Robin D. G. Kelley and an afterword from acclaimed activist-academic Nick Estes.

Border control continues to be a highly contested and politically charged subject around the world. This collection of essays challenges reactionary nationalism by making the positive case for the benefits of free movement for countries on both ends of the exchange. Open Borders counters the knee-jerk reaction to build walls and close borders by arguing that there is not a moral, legal, philosophical, or economic case for limiting the movement of human beings at borders. The volume brings together essays by theorists in anthropology, geography, international relations, and other fields who argue for open borders with writings by activists who are working to make safe passage a reality on the ground. It puts forward a clear, concise, and convincing case for a world without movement restrictions at borders. The essays in the first part of the volume make a theoretical case for free movement by analyzing philosophical, legal, and moral arguments for opening borders. In doing so, they articulate a sustained critique of the dominant idea that states should favor the rights of their own citizens over the rights of all human beings. The second part sketches out the current situation in the European Union, in states that have erected border walls, in states that have adopted a policy of inclusion such as Germany and Uganda, and elsewhere in the world to demonstrate the consequences of the current regime of movement restrictions at borders. The third part creates a dialogue between theorists and activists, examining the work of Calais Migrant Solidarity, No Borders Morocco, activists in sanctuary cities, and others who contest border restrictions on the ground.
