Learning objectives
The aim of this course is twofold. First, to learn how to analyse time-series (typically macro-) data. In particular, how to identify the effect of past shocks on the current state of the world, how to forecast future values and how to model the dynamic interaction between different series.
Second, to analyse the main challenges faced by economists and social scientists in answering empirical questions using micro‐data. The main emphasis will be on learning how to establish causal relationships between different variables and how to use this evidence to inform policy makers' decisions.
Expected learning outcomes
By the end of the course students will be able to:
Understand the difference between a time series and an independent random sample.
Apply non-parametric and parametric techniques to model time series.
Choose and estimate parametric models for time series.
Compute the impulse response function.
Forecast future values.
Handle real‐world data.
Identify causal effects using micro-data
Link econometric theory with data work and produce an insightful and coherent empirical analysis.
Course syllabus and organization

Single session

Responsible
Lesson period
First trimester
Organization of teaching
The lectures will take place on the Microsoft Teams platform. It will be possible to follow these in real time as per the schedule in the timetable. It will also be possible to access the recordings on the same platform.

The modality and criteria to take part to the lectures in person, that may require a booking in advance with a specific app, will be advertised in advance on ARIEL. Additional information regarding updates in response to the development of the Covid-19 pandemic will also be advsertised on the same site.

Syllabus and teaching material
The syllabus and teaching materials are not affected.

Assessment
Exams from distance will take place using the platform exam.net. A complete guideline to the assessment is available on ARIEL.
Prerequisites for admission
There is no formal prerequisite.
This course requires knowledge of inferential statistic and of matrix algebra.
Some previous knwoledge of econonometrics is recommended for the micro-econometrics and causal inference module.
Assessment methods and Criteria
One written exam for Time Series.

- Microeconometrics and causal inference
Only for the first session of finals students will be provided the opportunity to handle a project paper on the part of casual inference and one for micro-econometrics. The topic can be freely selected by the student. The focus of the paper needs to be an application of one of the approaches discussed during the lectures.
After the first session of finals, the chance to handle a paper will no longer be available and the student needs to take a written text.
