Like many other social scientific terms, the exact meaning of globalization has always been unclear. It does not have a single point of origin, but emerged in the mid to late 1980s in several disciplines. In the general sense, globalization is the increasing interaction of people through the growth of the international flow of money, ideas, and culture. It first manifested in media and cultural studies as early as the 1970s—the spread of TV, telephones, information and communication technology (ICT), and other media provided an enduring image of the technological “shrinking” of space, a defining trait of globalization. Advances in the means of transport (such as the steam locomotive, steamship, jet engine, and container ships) and in telecommunications infrastructure (including the rise of the telegraph and its modern offspring, the Internet and mobile phones) have been major factors in globalization, generating further interdependence of economic and cultural activities. In connection to the study of globalization, global political economy (GPE), or international political economy (IPE), is an academic discipline that analyzes economics and international relations. As an interdisciplinary field, it draws on a few distinct academic schools, most notably economics, political economy, political science, sociology, history, and cultural studies. Other topics that command substantial attention among IPE scholars are international trade, international finance, financial crises, macroeconomics, development economics, and the balance of power between and among states and institutions.
