The econometric model, how do we obtain data? statistical inference, a research format. | Chapter 1 An Introduction to Econometrics Why Study Econometrics Econometrics is a set of research tools also employed in the business disciplines of accounting finance marketing and management. It is also used by social scientists specifically researchers in history political science and sociology. Econometrics plays an important role in such diverse fields as forestry and in agricultural economics. A gap exists between what you have learned as an economics student and what economists actually do. Most economists use economic data to estimate economic relationships test economic hypotheses and predict economic outcomes. Studying Slide Undergraduate Econometrics 2nd Edition-Chapter 1 econometrics fills a gap between being a student of economics and being a practicing economist. If your goal is to earn a master s or . degree in economics finance accounting marketing agricultural economics sociology political science or forestry you will encounter more econometrics in your future. By taking this introduction to econometrics you will gain an overview of what econometrics is about and develop some intuition about how things work before entering a technically oriented course.
