Conoscenze e abilità da conseguire

At the end of the course the student knows the main applied statistical methods to extract useful information from business databases and to support the management decision process in the face of uncertainty. In particular the student is able to apply statistical indicators and linear/non-linear regression analysis for the evaluation of firms’ performance, the study of customers’ behavior and the choice of an investment project, by using a statistical software. At the end of the course the student is able: - to select and apply the most appropriate methodology to quantitatively analyze the business phenomena; - to critically interpret empirical results.

Contenuti

By the end of this course, you should be able to:
1. explain what is meant by business statistics, the difference between risk and uncertainty and why each plays a fundamental role in the world of business; 2. describe the different kinds of market structure and use appropriate data sets to measure market concentration. Be able to combine this with other analysis to understand the degree of competition in a market and how it can affect a firm’s pricing and marketing strategies; 3. explain the importance of randomised experiments for making causal inferences; 4. explain the challenges of making causal inferences in non-experimental settings, such as with observational data or databases held by the firm; 5. use a multiple regression framework to estimate the relationship between dependent and
independent variables in appropriate business data sets and assess the quality of the analysis for estimating causal effects; 6. explain what is meant by endogeneity and why it can arise due to problems of omitted variable bias, simultaneity bias and measurement error; 7. explain how the methods of instrumental variables and regression discontinuity designs can overcome the endogeneity problem and list and describe other methods that may be used; 8. explain what is meant by decision theory and the value of perfect information; 9. be able to use the above methods to extract and analyse business-relevant information from appropriate case studies and data sets, present it and report it in a form which will provide clear and accessible decision-support to managers.
