The primary objective of the fourth edition of Essentials of Econometrics is to provide a user-friendly introduction to econometric theory and techniques. This text provides a simple and straightforward introduction to econometrics for the beginner. The book is designed to help students understand econometric techniques through extensive examples, careful explanations, and a wide variety of problem material. In each of the editions, I have tried to incorporate major developments in the field in an intuitive and informative way without resort to matrix algebra, calculus, or statistics beyond the introductory level. The fourth edition continues that tradition.
New Chapter 15 covering simultaneous equation models. The key concepts of the simultaneity problem, the identification problem, indirect least-squares (ILS) and two-stage least-squares (2SLS) are introduced.
An appendix to Chapter 1 provides a list of web sites directing the student to a variety of economic data.
Chapter 3 now covers bootstrap sampling. Monte Carlo (simulation) experiments are introduced in extending the discussion of the sampling, or probability, distribution of a random variable and the Central Limit Theorem (CLT).
Chapter 11 on heteroscedasticity includes White's general test of heteroscedasticity and White's heteroscedasticity-corrected standard errors and t-statistics.
· Chapter 14, Selected Topics in Single Regression includes spurious regression, the unit root text of nonstationarity and random-walk models.
