Abstract [sv]

Syftet med denna undersökning är att analysera eventuella löne- och sysselsättningseffekter generade av återinförandet av ROT-avdraget 2008. Återinförandet sågs som en permanent åtgärd med målet att motverka så kallade svartarbeten och öka byggandet i Sverige. Vi vill med denna undersökning utvärdera vilka löne- och sysselsättningseffekter som ROT-avdraget bidragit till. En difference-in-difference metod kommer att användas för att analysera data insamlade från aktiebolag i Sverige, aggregerat till branschnivå. Aggregeringen görs för att våra resultat skall vara direkt jämförbara med tidigare studier, samt för att inte exkludera den effekt som orsakas av att nya företag i dessa branscher kan ha startats på grund av reformen. Difference-in-difference metoden går ut på att en behandlad grupp bestående av de byggbranscher som påverkats av ROT-avdragets införande jämförs med en kontrollgrupp bestående av övriga branscher före och efter reformen. Våra resultat visar att den genomsnittliga lönesumman per anställd inte påverkats av reformen, medan reformen givit en ökning i det genomsnittliga antalet anställda i ROT-branscherna.

Abstract [en]

The purpose of this paper is to analyze the possible wage and employment effects generated by the reintroduction of the ROT-deduction in 2008. The reintroduction was seen as a permanent measure, and the aim was to counteract undeclared work and to stimulate and increase the building in Sweden. With this paper, we want to evaluate the wage and employment effects that the ROT-deduction contributed to in Swedish construction companies, more specifically limited companies in the ROT industry. A difference-in-difference method will be used to analyze data collected from limited companies in Sweden, aggregated to industry level. Aggregation is made for our results to be directly comparable to previous studies, and to not exclude the effect caused by new companies in the ROT-industry that may have started due to the reform. The difference-in-difference method involves that a treated group consisting of the construction industries affected by the introduction of the ROT-deduction is compared to a control group consisting of other industries before and after the reform. Our results show that the average wage per employee is not affected by the reform, while the reform has increased the average number of employees in the ROT-industry.
