Economics is the nexus and engine that runs society, affecting societal well-being, raising standards of living when economies prosper or lowering citizens through class structures when economies perform poorly. Our society only has to witness the booms and busts of the past decade to see how economics profoundly affects the cores of societies around the world. From a household budget to international trade, economics ranges from the micro- to the macro-level. It relates to a breadth of social science disciplines that help describe the content of the proposed encyclopedia, which will explicitly approach economics through varied disciplinary lenses. Although there are encyclopedias of covering economics (especially classic economic theory and history), the SAGE Encyclopedia of Economics and Society emphasizes the contemporary world, contemporary issues, and society.
