| Course outline |
Learning outcomes for participants: At the end or during the course participants will be able: (a) To conceptualise the vital concepts and issues of econometric analysis and modelling; (b) To apply the econometric concepts and tools to understand and analyse their countries' economic behaviour; (c) To understand the complex nature and inter-linkages among sectors and markets of their economies; (d) To acquire skills and knowledge of econometric modelling for strategic thinking and understanding; (e) To acquire methodological foundation necessary for future studies; and (f) To synthesis of ideas, views and evidence. The knowledge and skills obtained from the course will be useful for business mangers and development practitioners in analysing and maximising the effectiveness of polices and business decision. Aware of econometric tools are necessary for effective decision making in business and policy administration/management. (a) Class room lectures; (b) Computer workshops and in class discussion; (c) Reading assignments; and (d) Homework assignments and group discussion. |
| Course objective |
Econometrics has become one of the most important tools for policy makers of the day in quantifying the impacts of various policies on their economies. To tackle practical problems, policy makers and business managers need to build econometric models. The objectives of the course are: (a) to understand important econometric tools/techniques; (b) to learn simple models; and (c) to use econometric techniques in real world policy analysis. This course is also designed to provide the practical illustration of techniques used in applied macroeconometric. This course is highly recommended for students who intend to do quantitative analysis (using time series data in particular) in their thesis writing. |
