Georgia State's Department of Economics, recently ranked number one in Georgia by the Southern Economic Journal, has won national acclaim for its insightful research into practical economic topics. Its concentrations in environmental and labor economics, urban and regional economics and public finance are setting new academic standards in programs of study that combine solid research with practical policy education. Economists use mathematical models to develop programs that predict, for example, the nature and length of business cycles, the effects of inflation on the economy, or the effects of tax legislation on unemployment levels. Preparing reports on the results of their research is an important part of the economist's job. Being able to present economic concepts in a meaningful way is particularly important for economists who are involved in making policy for their organizations.
