Other investigations like the ones written by İçduygu & Millet (2016) and İçduygu & Diker (2017) study possible ways of integrating Syrian refugees in the society from a legal and a social standpoint.In particular, these authors highlight the importance of the current legislative challenges faced by Turkey, including the enactment of regulation that prevents refugees from taking on informal jobs or incentives to employers to provide formal jobs to refugees. Our research not only confirms this extent, but is also able to quantify the role of legal constraints on Syrian's ability to obtain a work permit. An item related to integration is skill building, however, our research finds a triple threat in this regard, first, the proportion of highly qualified Syrians is decreasing in younger cohorts, second, the few Syrians with tertiary studies tend to work in jobs for which they are overqualified and, at last, their qualifications are not rewarded in the same way Turkish natives' ones are. The need for skill building is well explained in, for instance, İçduygu & Diker (2017), who argues in favour of skill building programs for refugees as a necessary step toward their integration in the labour market. In addition to these challenges, the studies prepared by İçduygu & Millet (2016) and ORSAM (2015) mention an increasing probability that Syrian refugees will become permanent residents of Turkey, which raises the importance of investments in education. However, and irrespectively of whether 3.6 million Syrians become Turkish nationals or not, we are no longer talking about a short-term humanitarian response but, rather, about a long-term integration problem which demands effective policy responses.Existing data sources. Despite some successful attempts at producing studies on the impact of Syrian refugees at the macroeconomic level, little is known about their personal circumstances. One of the most remarkable attempts from a sociological point of view is the Syrian Barometer, see Erdogan (2017), a national-level survey covering 11 provinces and interviewing 1,235 Syrian families, reaching out, in total, 7,591 Syrians. Even though attractive in terms of understanding Turkish nationals' sentiment with regards the Syrian population, it lacks, beyond a few basic questions, deep information with regards Syrians' labour market performance.Other ad-hoc surveys on Syrian refugees' socio-economic conditions are not as ambitious and the few existing sources lack national representativeness. Still, a remarkable effort in gathering data at the microeconomic level can be found in Uçak & Raman (2017). This research uses a survey on Syrian-owned SMEs to provide a snapshot of this type of companies, including the value of having them for the Turkish economy. With regards to the dataset, which can be taken as a small-scale enterprise survey, it included visits to 230 businesses equally split between Istanbul and Gaziantep on the condition that they were legally established, currently active and had at least an employee. On the negative s...
