Abstract
This study is a randomized controlled trial (RCT) on the effects of mentoring on SMEs in Norway. We aim to get a better understanding of firm development and dynamics in the presence of public interventions. Does mentoring affect firm performance and firm-survival? Does it matter what type of state aid a firm is granted; mentoring versus the financial equivalent of the service?
The trial is a three-armed parallel randomized control trial. The first group will receive mentoring; the second group will receive the financial equivalent to the cost of the mentoring, and the third group is a control. The population consists of small and medium-sized enterprises who have applied for and been granted financial support from Innovation Norway. From this population, we draw the three groups. All firms that are part of the trial are established 5 or fewer years ago. The total sample size will be 300 firms.
Exploiting a rich data set based on a set of matched register data, we will be analyzing both firm performance and external effects using a wide set of outcomes and measures. We will have information both about the firms and the people connected to the firms by employment, ownership or board members. We will assess outcomes twice after the intervention to study both short-term results and long-term results.

Interventions
Intervention(s)
Mentoring:
The first treatment group will receive a mentoring service.

Cash transfer
In the second treatment arm, the participants will receive the monetary equivalent to the mentoring service.

Primary Outcomes
Primary Outcomes (end points)
Firm performance
Primary Outcomes (explanation)
To address the impact of the interventions on firm performance we shall analyse a range of outcomes. We are moreover planning to assess firms’ performance twice after the intervention in order to study both short term results and long-term results. The first assessment will be one year after the last participant has entered the trial. While we will consider many of the same outcomes at both evaluations, we may expect the intervention to have different impacts in the short term than in the long term.
Secondary Outcomes
Secondary Outcomes (end points)
Amongst the outcomes to be considered:
• The time before the company yields a dividend for the entrepreneur
• The time before the product(s) is(are) commercialized
• New investors (increase in equity)
• Revenue growth
• Growth in the number of employees
• Survival
• Productivity
• Patents
• Exports (destinations and customers)
• Import of intermediates and capital goods (source countries and suppliers)
• Networks
• External effects through e.g. the labor market and investors/owners
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
The RCT is a parallel design with three arms. Two arms are designated treatment groups, and the third is a control group. The population consists of approved applicants to a set of different financial support programs. Among those who receive approval on the application for the financial support, we draw one-third to receive additional mentoring, one-third to receive a cash transfer equivalent to the expenses associated with the mentoring and one-third as a control.
By including the second treatment group, we remove the capital part of the mentoring service from the effect measure. This makes it possible not only to study the effect of additional support but to isolate the value of the service provided.
We follow the strategy of intention to treat. This implies that all recipients have the option of declining both financial support and additional treatment. Those who decline will still be part of the study.
