We find that our new distance measure reduces the estimated border and adjacency effects but does not eliminate them. We then apply our methods to data on interstate trade in the United States and inter-member trade in the European Union. We show how use of the existing methods for calculating distance leads to "illusory" border and adjacency effects. Our goal here is to develop a correct measure of distance that would be consistent for international as well as intra-national trade flows. We argue in this paper that, because distances are always mismeasured in the existing literature, the border effects may have been mismeasured in a way that leads to a systematic overstatement. This puzzle was first presented by McCallum (1995) and has gone on to spawn a large and growing literature on so-called border effects. The measured effect of national borders on trade seems too large to be explained by the apparently small border-related trade barriers. Mapping the Transnational World is a big empirical step forward for the study of international migration and mobilities."-Adrian Favell, University of Leeds "This spectacularly ambitious and potentially paradigm-shifting work builds what is indeed one of the first systematic attempts to document, analyze, and explain the totality of migrations on a planetary scale. The use of network-analytic techniques to model these cross-border connections is impressive."-Jason Beckfield, Harvard University I appreciate the breadth of coverage: the description of regionalization and globalization across eight types of human activity over five decades is a big contribution all on its own. "Mapping the Transnational World offers a large-scale look at various human connections spanning national borders. Revealing why a truly global society is unlikely to emerge, Mapping the Transnational World highlights the essential role of interaction beyond borders on a planet that remains spatially fragmented. Unveiling proximity-induced regionalism as a major feature of planet-scale networks of transnational human activity, Deutschmann provides a crucial corrective to several fields of research. Moreover, this pattern remained extremely stable during the five decades studied-1960 to 2010.
He explains that the spatial structure of transnational human activity follows a simple mathematical function, the power law, a pattern that also fits the movements of many other animal species on the planet. Is it really a fully globalized world in which everything is linked, as popular catchphrases like “global village” suggest? Through a sweeping comparative analysis of eight types of mobility and communication among countries worldwide-from migration and tourism to Facebook friendships and phone calls-Mapping the Transnational World demonstrates that our behavior is actually regionalized, not globalized.Įmanuel Deutschmann shows that transnational activity within world regions is not so much the outcome of political, cultural, or economic factors, but is driven primarily by geographic distance. Yet, we still know little about the overall structure of this transnational world.

The GeoDist webpage provides two distinct files: a country-specific one (geo_cepii)and a dyadic one (dist_cepii) including a set of different distance and common dummy variables used in gravity equations to identify particular links between countries such as colonial past, common languages, contiguity. For most of them, different calculations of “intra-national distances” are also available. We have calculated different measures of bilateral distances available for most countries across the world (225 countries in the current version of the database). GeoDist provides several geographical variables, in particular bilateral distances measured using citylevel data to assess the geographic distribution of population inside each nation. Title CEPII's GeoDist Datasets Version 0.1 Description Provides data on countries and their main city or agglomeration and the different distance measures and dummy variables indicating whether two countries are contiguous, share a common language or a colonial relationship. GeoDist makes available the exhaustive set of gravity variables used in Mayer and Zignago (2005). Working Papers from CEPII research center Notes on CEPII’s distances measures: The GeoDist database
