## 计量经济学导论A thorough understanding of econometrics allows students to better understand the relationships on which people, businesses, and governments base their decisions. And to make econometrics relevant in an introductory course, interesting applications must motivate the theory and the theory must match the applications. This text motivates the need for tools with concrete applications, and then provide simple assumptions that match the application. Because the theory is immediately relevant to the applications, this approach makes econometrics come alive. Real-world questions and data are integrated into the theoretical development, and appropriate coverage is given to the substantive findings of the resulting empirical analysis. And topics presented in the text reflect modern theory and practice. |
