<p>What is the total, summarized effect of immigration? Up to this date researchers have found both small positive effects and small negative effects for the same variable (e.g. wages or unemployment). As far as I know no one has yet focused on the total effect. With panel data on a bundle of variables for 22 OECD countries between 1970-2007, using multiple regression analysis I will estimate each variable individually and add together the signs of the effects to one combined sign (+/-/0). I find that the total, summarized effect of immigration tends to be slightly positive for OECD destination countries (under my assumptions).</p>
