OVERVIEW

The analysis of the historical series has progressively acquired greater importance in the financial sector. The ability to model, estimate and predict the behavior of time series and its main properties is a fundamental element for those who want to approach the financial field.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides a survey of the theory and application of time series models in financial econometrics. Students are introduced to time series analysis of linear univariate and multivariate covariance stationary models with short and long memory parameterization. The course then employs linear time series knowledge to introduce studen ts to time series financial econometrics models, particularly discrete-time parametric ARCH models. The main objective of this course is to develop the skills needed for modelling and forecasting assets volatilities and their co-movements in financial markets. The course aims to provide students with a strong theoretical understanding of volatility models and techniques for estimations, assessment and forecasting in financial markets under a variety of degree of shock persistence. Theoretical lectures are complemented by computer classes whose aim is to enable the students to develop computational skills in MATLAB for empirical research

AIMS AND LEARNING OUTCOMES

The course is designed to introduce the econometric tools used in in time series analysis and finance, and to gain understanding of the sources and characteristic of financial data as well as current and classic applications. The interaction between theory and empirical analysis is emphasised. Students are introduced to time series analysis of linear univariate and multivariate covariance stationary models with short and long memory parameterization. Llinear time series knowledge is employed to introduce students to time series financial econometrics models, particularly discrete- time parametric ARCH models.. The course aims to provide students with a strong theoretical understanding of volatility models and techniques for estimations, assessment and forecasting in financial markets under a variety of degree of shock persistence. 

PREREQUISITES

topics related to the basic course of econometrics and statistics, in particular with reference to estimation methods (OLS and massiverosimigliaza) and hypothesis testing, and the fundamentals of matric algenbra

TEACHING METHODS

In presence lessons

N.B.

In case of changes in the sanitary and epidemiological situation,.if it is not possible to carry out activities in presence, the methods of delivery of the courses will be adopted decided by the CDD (mixed mode in presence and online), postponing to Aulaweb for any further updates that may occur necessary during the academic year (both as regards the
delivery methods, both as regards the examination procedures),
