Mathematics For Economists Mark Dean Introductory Handout for Fall 2014 Class ECON 2010 - Brown University 1 Aims This is the introductory course in mathematics for incoming economics PhD students at Brown in 2014. For example, suppose Microsoft is currently selling today at $40 per share. One of the most widely used distributions in economics is the standard normal distribution. Statistics allows economists to make forecasts and determine the probability of an occurrence. Economics Has a Math Problem. Test your understanding of the learning outcomes in this module by working through the following problems. For work to add to this primary objective, it is not sufficient that the mathematical reasoning be new and correct. In business and economics there are many applied problems that require optimization. Economics applications are given throughout the text.
