Economics is a year-long class, usually taken a student's junior year, that is required for graduation. We start with basic economic concepts, such as scarcity and allocation, and examine the different types of allocation systems societies use. Next we move into micro-economics where we learn about demand/supply/price, the forms of market organization, and institutions in our economy. In macro-economics we learn how to measure aggregate economic activity, the problems of unemployment and inflation, examine fiscal and monetary policy and learn about economic growth and development. We finish the year with international economics where we examine topics such as trade, global interdependence and the challenges facing different economies world-wide.
