Evaluation of a change in the Norwegian legislation: The effects of making audit voluntary for small firms

On behalf of the Norwegian Ministry of Finance, I (together with some of my colleagues) undertook an evaluation of a change in regulation that took place in May 2011; Making auditing voluntary for small limited liability firms. The report is available in Norwegian only, but I have written a summary in English that describe the topics we investigate, how we conducted the research, and the main findings.
