Workshops 2025-2026
1st Workshop: Geospatial Data
Date: Saturday 24/01/2026 – Assistant Prof. Vasilis Logothetis, UoI
Title: Geospatial Data in Economic Research: Basic Concepts and Applications
Description: This workshop offers a friendly introduction to the use of Geographic Information Systems (GIS) in economic research. It will present the main types of spatial data as well as the fundamental geoprocessing methodologies that allow the use of sources such as satellite images, historical maps, and distance data. Through examples from publications, it will be shown how spatial data open up research perspectives and provide more reliable identification strategies (such as IV and RDD). The aim is for participants to become familiar with the relevant tools and to understand their usefulness in economic analysis and research.

Participants are advised to download the open-source QGIS program (https://qgis.org/) in order to use the data and follow the replication. In addition, for convenience, when the replication is finalized, I would like to ask them to download some additional files. Could this be done closer to the seminar date? If not, then we will download them during the seminar break, if foreseen.
2nd Workshop: Bayesian Analysis
Date: Saturday 21/03/2026 – Associate Prof. Grigorios Emvalomatis, UoC
Title: Introduction to Bayesian Analysis: Theory, Applications, and Software Packages
Description: The Bayesian approach to data analysis provides an intuitive way to handle stochasticity in econometric models, as well as the ability to specify models tailored to the particularities of each application. In this workshop we will cover the fundamental concepts of Bayesian analysis and, while briefly examining how these concepts apply to the linear model, we will quickly move on to more complex models, such as stochastic volatility and mixed-frequency VAR. The goal is for participants to become familiar with software packages that simplify the specification and estimation of models using the Bayesian approach. We will mainly use the packages JAGS (Just Another Gibbs Sampler) and Stan, which we will run through R. Finally, we will briefly review the capabilities of Python’s PyMC package.
If you would like to run the analysis on your own computer during the workshop, please install the following packages beforehand:
1. R and RTools (RTools is required to use Stan)
2. Optionally, RStudio or Jupyter Lab
3. The R packages rstan, rjags, R2jags and coda
4. JAGS
5. Python with the packages pymc, arviz, numpy, pandas, and matplotlib

Workshops 2024-2025
Workshops on “Causal Inference”
Why do we care? A large proportion of real-life questions of interest are questions of causality, not just correlation. Causal inference encompasses the tools that allow social scientists to determine what causes what.
What we will do? Hands-on using real data and Stata software sequence of four seminars introduce researchers to necessary methods to arrive at meaningful answers to the questions of causation, using a range of advanced modeling techniques and coding instructions in Stata. All material (files and codes) will be provided one week in advanced.
Keywords: endogeneity, causal effects, identification, fixed-effects, instrumental variable (IV) analysis, potential-outcome, policy evaluation, counterfactuals, Difference-in-Difference (DiD) analysis, treatment and control group.
PART A
Manthos Delis
Professor, Audencia Business School
Seminar 1:
-> January 25, 2025
Why do we need causal inference and what are the key endogeneity problems faced by empirical research in economics and finance. The use of fixed effects and Instrumental variables regressions.
Seminar 2:
-> February 22, 2025
Difference-in-differences (DiD) as a natural experiment in social sciences and the discontinuity design regression.
PART B
Alexandros Bechlioulis
Assistant Professor, University of Ioannina
Seminar 3:
-> March 1, 2025
How do we estimate the impact of a policy intervention? What is a treatment and a control group? Canonical and modern difference-in-difference (DiD) methodologies for a two-period analysis.
Seminar 4:
-> April 5, 2025
Multi-period frameworks: Assume now more than two time periods in which units may be treated at the same time or different points in time. Heterogeneous robust estimators for staggered treatment timing.
