Workshop on Sibling Fixed Effects Models

October 12 and 14 2021

This workshop provides an introduction to fixed effects models with a focus on sibling fixed effects. In these models, one sibling serves as the control for another sibling. By these means, sibling fixed effects models control for unobserved variables that are shared among siblings.

The workshop is structured into three parts. The first part discusses the central ideas motivating sibling fixed effects models and how they relate to individual fixed effects models. This introduction requires no prior knowledge of fixed effects models.

The second part of the workshop provides practical exercises using Stata, allowing participants to implement and interpret these (sibling and other) fixed effects models themselves.

The third and final part of the workshop uses some published studies using sibling fixed effects models as examples of how the approach can actually be implemented. This part also discusses the assumptions underlying sibling fixed effects models, their limitations, and the critiques which have emerged against them.

Causal Inference for nonexperimental data

 17-19 March 2021 (12 hours)

By Bruno Arpino, Department of Statistics, Computer Science, Applications, University of Florence, Italy

What is the effect of smoking on health? Does having an additional child increase the risk of poverty? Are development policies targeted on small firms effective in increasing investments?

Most studies in the social sciences are motivated by questions that are causal in nature.

However, in these areas experiments are not always possible because of ethical or practical reasons and the estimation of causal effects has often to rely on observational studies. The validity of inference will then strictly depend on the plausibility of the assumptions underlying the employed statistical techniques.

This course will cover some of the most popular techniques for estimating causal effects with observational data: propensity score matching, instrumental variable regression, regression discontinuity designs and fixed effects models. Special emphasis will be placed during the course on discussing the plausibility of the identifying assumptions, the data requirements and other practical and theoretical challenges for the implementation of each method.

This short course will offer participants theoretical and applied perspectives on the covered topics. Examples will be drawn from political science, sociology, economics, public health and policy evaluation. Lab sessions will demonstrate the implementation of the covered techniques using the software STATA.

Introduction to R

by Simon N. Chapman, INVEST Flagship, Department of Social Research, University of Turku, Finland

6-7 April 2021

Many researchers now work almost exclusively in the R programming environment, but what is R and how does one even get started? Why should I use R over (preferred statistics program)? What is a function and what is a package? What do those square brackets mean? 

Learning R can seem like a daunting task, like trying to climb Everest with no tools and no mountaineering experience. There is no need to fear though: as the famous idiom goes, the best way to eat an elephant is one bite at a time. In this course, we will break the basics of R into bite-sized chunks.

This course aims to give participants a starting point for working within the R environment, and is suitable for absolute beginners and more experienced programmers alike. Learn to import and export objects, view and summarise datasets, create variables, and much more.

Simon Chapman is a senior researcher in the INVEST Flagship at the University of Turku. He obtained his PhD in evolutionary biology from the University of Turku in 2020. His current interests are intergenerational relations, cooperation and conflict within families, life history evolution, and the impacts of parental leave on the life-course. His work has been published, amongst others, in Current Biology, Nature Communications, Evolution & Human Behavior, and Biology Letters.

Introduction to Social Science Genetics 10.-12.11.2020

by: Felix Tropf

A growing number of social science data sources are providing molecular genetic data and researchers all over the world are interested in utilizing this information in order to better understand various social phenomena. In this course, we will learn about the history of social science and behaviour genetics as well as about the state of the art research and cutting-edge methods. After attending this workshop, participants should have a basic understanding of the fundamental advantages of integrating genetics into social science. They should understand the basic technical terms from quantitative genetics literature and be able to read and interpret studies concerning social science genetics. They should be able to conduct basic quantitative genetics analyses and interpret their findings. Participants need an interest and a basic understanding of quantitative social science research and some experience concerning the software R & Stata.

We will start with a general introduction of genetics in social sciences discussing potential research questions we can answer using genetic data. We subsequently learn about the theory behind twin and family models and how to estimate heritability as the proportion of observed variance in an outcome, which is explained by genetic effects. We move on to see how heritability is measured using molecular genetic data and discuss various challenges and applications. We use Plink software to prepare and analyze genetic data and GCTA software to estimate quantitative genetic models.

We will discuss how to genetic variants are discovered, which are associated with social science outcomes of interest and how we can utilize these results in social science research in terms of controlling for confounding effects, dealing with genetic heterogeneity in social science models, estimating gene-environment interaction models and using genes as instrumental variables. Substantively, we will rely on recently published genetic discovery studies on educational attainment, subjective well-being and fertility.
