About half of them are academic economists, who engage in teaching,
writing and doing research in colleges and universities. They also write textbooks
and journal articles, develop and test new theoretical models, provide consulting
services to governments and businesses, and engage in a variety of other
professional activities. The other half of the profession works for business or
government. Business economists forecast sales and costs, help firms anticipate (or
try to influence) government policy.
