Wooldridge M. Jeffrey. (2009) Introductory Econometrics. A Modern Approach. Michigan State University. Fourth Edition.Economics is about the distribution of limited resources among alternative uses. To explain this process, economists develop simple economic models by abstracting from reality. These models have some mathematical foundations and encompass only the necessary characteristics of the market. The study discusses the theory behind the development of such models and the problems encountered in the process. As no model describes reality perfectly, the question is to tell whether a model is good enough. Moreover, the study discusses a new method of conducting empirical research by utilizing experimental data, where economists try to find natural experiments and show causal relationships between variables.geeconomic model, causation, ceteris paribus, optimization, field experimentArticle
