Experimental Design Details
The SEA intends to provide the information treatment to 2,000 individuals. This number is selected based upon considerations of available staff resources.
The population of individuals subject to debt enforcement at the SEA was 369,038 at the point in time for the application of the inclusion criteria (April 2022). In the SEA organization, these individuals belong to five geographically organized divisions. This means that each division handles debt enforcement of a specific share of the total number of debtors according to the following table:
TABLE 1: Share debtors of population by debt enforcement division at the SEA
Division, Share
1, 28 %
2, 12 %
3, 23 %
4, 19 %
5, 17 %
Overindebted individuals that may qualify for debt relief are selected from the population based upon the following inclusions criteria:
1. Individual with Swedish personal identification number
2. Not deceased
3. Not personal bankruptcy (swe. konkurs)
4. Not prohibition to conduct business (swe. näringsförbud)
5. Not subject to intermittent sequestration (swe. kvarstad)
6. Not handled by special debt enforcement section
7. Private debt > SEK 90,000
8. Share of private debt pertaining to damages pertaining to criminal offence < 30 per cent
9. Not applied for debt relief during 2021-2022
10. Not included in the information intervention conducted in 2021
11. The debtor either has no other recorded properties by the SEA than bank account, equity fund, listed shares, or car or other vehicle with a value that is too low to motivate attachment.
12. The debtor is not subject to salary garnishment.
13. The SEA has previously investigated the debtor with the aim to conduct debt enforcement but found that there is not enough attachable properties to pay the debts on at least one occasion (swe. utredningsrapport).
14. There is recorded contact with the debtor since July 2020.
The application of the inclusion criteria on the total population of individuals subject to debt enforcement identifies 3,647 individuals. 2,000 individuals are randomized to treatment in five stratas corresponding to the debt enforcement divisions at the SEA. The remaining individuals are assigned to the control group. Each division is assigned a specific number of individuals in the treatment group based upon their shares of the total population according to Table 1. This means that each division handles only debtors that belong to their share of the total population. The debtors are assigned to the divisions based upon their residency, i.e., where they live.
However, inclusion criterium no. 14 is based on a specific registration in the SEA database regarding contact with the individual subject to debt enforcement. The application of this registration in day-to-day debt enforcement operations is unevenly distributed across the five divisions according to Table 2.
TABLE 2: Share debtors with registered contact by debt enforcement division at the SEA
Division, Share debtors with registered contact
1, 16 %
2, 14 %
3, 17 %
4, 33 %
5, 31 %
Table 2 shows that the share of individuals with the contact registration in the database is approximately 30 per cent for two of the debt enforcement divisions, while it is approximately 15 per cent for the remaining three. This is explained by biased implementation of the case handling protocol for this specific registration across the divisions. Accordingly, the stratas in the control groups corresponding to the two divisions with greater propensity to register contact with the individual subject to debt enforcement, are larger compared to the other three divisions as shown in Table 3.
