Experimental Design
Participants are recruited via a survey provider that sent out letters to the managing director of all firms in Norway with more than 4 employees and with no experience of wage subsidies or job training in the last 3 years. The letter includes a link and QR code to an electronic survey, and we expect about 10 percent of all firms that received the letter to answer the electronic survey, and these firms constitute our sample.
The letters were sent out on a rolling basis starting April 22, 2025. Survey data collection will stop June 30, 2025, and this also marks the end of the intervention period (i.e., exposure to treatment). After that date, survey data will be made available to researchers, and this data will later be matched to register data from Statistics Norway and Nav covering the period from April 22, 2025, to June 30, 2026 (at least 12 months after the intervention period has ended).
As described in the Intervention section, firms are randomly assigned to one of four treatment groups:
T0. Control
T1. Sign-up link
T2. Sign-up link + General program information
T3. Sign-up link + General program information + Candidate and experience information.
T3 is the main treatment capturing the impact of reducing both sign-up frictions and misperceptions (by comparing T3 to T0). T1 is included to be able to identify the pure effect of reducing frictions (by comparing T1 to T0) and the pure effect of reducing misperceptions (by comparing T2 and T3 to T1). T2 is mainly included to understand whether the more specific information about candidates and firms' experience add something over-and-above the general program information that is already available on Nav's webpages (this will be tested by comparing T3 and T2).
The design allows us to test the following main hypotheses for each of the three main outcomes:
H1: One click sign-up and accurate information increases program sign-up, take-up and use (T3 > T0)
H2: One-click sign-up increases program sign-up, take-up and use (T1 > T0)
H3: Accurate information increases program sign-up, take-up and use (T3/T2 > T1)
As a more powerful test of accurate information, we will also do an analysis where we pool T2 and T3 (and compare it to T1). If we cannot reject that T2 and/or T3 are equal to T1, we will also consider a more powerful test of one-click sign-up by pooling T1, T2 and T3 (and compare it to T0).
Notice that we predict positive treatment effects of both the sign-up link and the information. A negative effect of one-click sign-up is difficult to reconcile theoretically, although it may well be zero. The provision of information on the other hand could potentially have a negative impact for at least two reasons: First, employers may, in contrast to what we expect, be negatively surprised by the information we provide which potentially could reduce perceived program usefulness. Second, the information may positively (or negatively) affect employers beliefs of other firms' use of the program (i.e., program popularity), which can reduce the specific firm's willingness to sign-up and use the program. We ask questions in the survey to be able to address both these possibilities (see M1-M4 in Secondary Outcomes). Note also that the possibility of a positive sign-up effect (T1>T0) and a negative information effect (T3 < T1) may result in a null effect for the combined treatment (T3 =T0 )
We have three sets of background variables: i) variables captured in firm register data, including the number of employees, sector, industry code, etc., ii) variables based on 4 questions from the survey capturing the firm's demand for low-skilled labor, and iii) variables based on 6 questions from the survey capturing prior knowledge and beliefs wrt wage subsides and job training. In addition to reporting unconditional treatment effects, we will report results conditional on a set of control variables with the objective to maximize precision in the estimated treatment effects. We will also use the background variables for heterogeneity analysis. In general, we expect the treatment effects to be driven by firms with more demand for (low-skilled) labor. Regarding prior knowledge and beliefs, we expect the information treatments to have larger impact on firms with a low score on the 6 questions (as these are firms with overly pessimistic priors), while we do not have a strong prediction for the sign-up link on this heterogeneity dimension (it could even be more important to remove the sign-up friction for firms with correct/optimistic priors). We will also do a heterogeneity analysis wrt firm characteristics such as sector and number of employees, without having any strong priors.
We do not have strong priors for the supplementary secondary outcomes (S1-S5), as they can be both positively or negatively affected, and most likely not affected at all. A null effect on these outcomes would, however, be positively interpreted as it suggets that firms can use active labor market programs without deteriorating effects on the regular work force.
