This has caused a detrimental impact on the global economy, particularly for SME's and Microbusinesses with unlimited liability/self-employed, leaving them vulnerable to financial difficulties, increasing the market share for oligopolistic markets as well as increasing the barriers of entry. Measurement One index of globalization is the KOF Index of Globalization, which measures three important dimensions of globalization: economic, social, and political. Another is the A.T. Kearney / Foreign Policy Magazine Globalization Index. Measurements of economic globalization typically focus on variables such as trade, Foreign Direct Investment (FDI), Gross Domestic Product (GDP), portfolio investment, and income. However, newer indices attempt to measure globalization in more general terms, including variables related to political, social, cultural, and even environmental aspects of globalization. The DHL Global Connectedness Index studies four main types of cross-border flow: trade (in both goods and services), information, people (including tourists, students, and migrants), and capital. It shows that the depth of global integration fell by about one-tenth after 2008, but by 2013 had recovered well above its pre-crash peak. The report also found a shift of economic activity to emerging economies. Support and criticism Reactions to processes contributing to globalization have varied widely with a history as long as extraterritorial contact and trade. Philosophical differences regarding the costs and benefits of such processes give rise to a broad-range of ideologies and social movements. Proponents of economic growth, expansion and development, in general, view globalizing processes as desirable or necessary to the well-being of human society. Antagonists view one or more globalizing processes as detrimental to social well-being on a global or local scale; this includes those who focus on social or natural sustainability of long-term and continuous economic expansion, the social structural inequality caused by these processes, and the colonial, imperialistic, or hegemonic ethnocentrism, cultural assimilation and cultural appropriation that underlie such processes. Globalization tends to bring people into contact with foreign people and cultures. Xenophobia is the fear of that which is perceived to be foreign or strange. Xenophobia can manifest itself in many ways involving the relations and perceptions of an ingroup towards an outgroup, including a fear of losing identity, suspicion of its activities, aggression, and desire to eliminate its presence to secure a presumed purity. Critiques of globalization generally stem from discussions surrounding the impact of such processes on the planet as well as the human costs. They challenge directly traditional metrics, such as GDP,
