This course is intended to provide a working knowledge of basic methods and principles of econometric practice. It will cover a wide variety of economic models and statistical methods. The basic tool will be the multivariate linear regression model but some attention will be devoted to discrete choice models as well as simultaneous equations models. Some theory will be developed in class, but the primary emphasis of the course will be on a sequence of specific problems involving the specification, estimation and interpretation of econometric models. There will also be a sequence of empirically oriented problem sets. .
