Although they may not recognize themselves as antiglobalists and are pro-capitalism, some economists who don't share the neoliberal approach of international economic institutions have strongly influenced the movement. Amartya Sen 's Development as Freedom ( Nobel Prize in Economics , 1999), argues that third world development must be understood as the expansion of human capability, not simply the increase in national income per capita, and thus requires policies attuned to health and education, not simply GDP. James Tobin 's (winner of the Nobel Prize in Economics ) proposal for a tax on financial transactions (called, after him, the Tobin tax ) has become part of the agenda of the movement. Also, George Soros , Joseph E. Stiglitz (another Economic Sciences Nobel prize winner, formerly of the World Bank, author of Globalization and Its Discontents ) and David Korten have made arguments for drastically improving transparency , for debt relief , land reform , and restructuring corporate accountability systems. Korten and Stiglitz's contribution to the movement include involvement in direct actions and street protest.
Understanding the location interdependence of multinational firms and how they agglomerate with one another is critical to designing and improving economic policies. These authors’ analysis, using a worldwide plant-level dataset and a novel index of agglomeration, yields a number of insights into the economic geography of multinational production. In addition to market access and comparative advantage motives, multinationals' location choices are significantly affected by agglomeration economies including not only vertical production linkages but also technology diffusion and capital-market externalities.
