Whereas I normally paraphrase information when I use a source for my literature review, I occasionally insert quotes (not to emphasize the information within the quote). All the reviews I've looked at so far tend to use quotations as little as possible. My question is whether it is discouraged or encouraged to present information through a variety of ways (ie. paraphrase, quotes, etc.)?
In looking at the relationship between immigrants in the Netherlands and the Dutch economy, Rootenberg et al. (2003) drew upon findings comparable to that of previous research results found in Sweden: while the impact varied across different immigrant groups, the average impact was inconsequential. Among the groups that produced a net gain were immigrants who arrived at a young age and those coming from a western society; all other groups represented a burden to the public sector. Hansen et al. (2015) and Gerdes et al. obtain similar results for Denmark. Their findings are summarized as follows: “Immigrants from richer countries have a positive fiscal impact, while immigrants from poorer countries have a large negative one. The negative effect is caused by both a weak labour market performance and early retirement in combination with the universal Danish welfare schemes" (Hansen et al. 2005).
