Regional Implementation Heterogeneity
RCTReview
Centralized active labor market policies are delegated to local municipal or regional job centers for execution. Variations in local administrative enforcement, casework practices, and private contractor usage create substantial implementation disparities that alter overall policy impact.
Picture this
When a central government issues a new policy, two regional branches might execute it differently: one branch follows every instruction strictly, while the other delegates the work to third-party contractors and simplifies the rules. As a result, identical laws produce vastly different real-world behaviors across regions.
What the evidence says
Southern Jutland delegated over 80% of treatment cases to private contractors (vs. ~40% for controls), yielding lower meeting frequencies (~30% weekly) but stronger threat effects; Storstrøm retained public administration (30% contractor usage) with higher meeting intensity (~40% weekly) but weaker threat-driven exit rate responses.
- Who was studied
- N = 4,513 unemployed individuals (Storstrøm: 1,174 treatment, 1,219 control; Southern Jutland: 1,055 treatment, 1,065 control).
- How
- Sub-sample stratification by county within an RCT duration framework, tracking meeting frequency and private agency contracting rates.
What to do
Evaluate policy trial datasets by stratifying analysis by administrative region and private contractor usage rather than assuming uniform central policy implementation.

"There are, in essence, two different experiments, one in each region, and they should therefore be analysed separately."
