CIDER

Casual Inference Data-driven Econometric Research

We estimate what policies do, and how far those estimates can be trusted.

CIDER is the econometrics and data science group at the Departmentof Economics, University of Southern Denmark. We are thirteenresearchers, organised around methods rather than around a field.Everyone here either develops tools in econometrics, causal inferenceand machine learning, or uses them on large administrative andhistorical data, and many of us do both.

The applications sit mainly in health economics, labour economics and economic history. Much of the empirical work rests on data that few groups can reach: Danish and Swedish administrative registers, cohorts followed from birth into old age, clinical trials costed alongside the trial itself, and archives that the group digitizes for itself.

Finding Better Policies to Help Children with Special Needs Thrive in School and Beyond
Examines how placement in special education affects children with special needs, both while they are at school and over the decade after they leave it. The work runs with the children and youth administration of Odense Municipality, which supplies the administrative records. Innovation Fund Denmark funds the doctoral component, held by Marco Knudsen

Long-term Social Change through Normalization Reforms Targeting Peoplewith Disabilities and their Peers
Studies the closure of institutions for people with intellectual and developmental disabilities in Denmark and Sweden between the 1980sand the 2000s, and their move into housing in ordinary neighbourhoods. It estimates what followed for the people concerned, for their families and for the neighbours who became their peers.

Beyond the Paycheck: Insights into the Effect of Unemployment, Organisational Change, and Job Security on Mental Health
Treats unemployment, organisationalrestructuring and job insecurity as causes ofpoor mental health rather than consequencesof it, using Danish employment legislation asthe source of variation. Mental health outcomesare measured in register data for the affectedworkers.

Do men and women react differently to an adverse health shock? Gender Differences in Healthcare Utilization and Health Behaviour
Uses unexpected cardiovascular events in the Danish registers as a shock to health, and compares how men and women change theiruse of health care afterwards. The question is how much of the gap between women's longer lives and their worse health at older ages runs through care seeking and health behaviour.

Moralization and Polarization
Builds a long series of state-of-the-statespeeches by American governors, from eachstate's entry into the Union to the present, anduses text analysis to date the point at which anissue acquires moral language. It then testswhether moralisation runs ahead of measuredpolarisation.

Causal Inference with Multiple IVs: Using Mendelian Randomization to Estimate the Causal Effects of Cannabis and Alcohol on Labour Productivity and of Creativity and Risk Taking on Entrepreneurship
Develops instrumental variable methods for settings with several instruments, and applies them with genetic variants as instruments in the IPSYCH cohort. The two applications estimate the effects of cannabis and alcohol consumption on schooling, earnings and health, and the effects of creativity and risktolerance on entering entrepreneurship.
