Financial Econometrics

Number of credits allocated: 6 ECTS Credits

Objective of the course (expected learning outcomes and competences to be acquired)

The aim of the course is to introduce students to econometric models that apply to finance and general economics. The material involves stochastic processes such as ARMA, GARCH, EGARCH, and heteroskedastic in Mean. Stochastic and deterministic non-stationarity as well as cointegration are also examined. Part of the lesson is student involvement with real data. All econometric exercises are held in the department's laboratory. Upon successful completion of the course, the students will:

• have fully understood the statistical properties of financial returns,
• be able to formulate and analyze the properties of ARIMA models as well as to evaluate, analyze and evaluate these models based on their predictive ability,
• have understood the principle of Maximum Likelihood and will employ it for estimation and statistical inference,
• have comprehended ARCH and GARCH models and will be able to apply them to financial assets that exhibit volatility clustering and dynamic asymmetry, and
• apply cointegration techniques to exemplify long-term and short-term relationships between financial data

Prerequisites: none
