|Title||Identifying Americans’ Immigration Policy Preferences via Conjoint Analysis|
|C1 Background and Explanation of Rationale||
Immigration is becoming a more divisive and contentious topic in American politics. While Republicans and Democrats were equally likely to support decreasing legal immigration to the U.S. in 2006, Republicans are now twice as likely as Democrats to favor decreasing legal immigration (Pew Research Center 2018). Additionally, a recent poll shows that 30 percent of Americans support President Trump’s immigration policies, 38 percent support the immigration policies of Democrats in Congress, and 24 percent support neither (The Washington Post 2018). The partisan division on the issue also increased over the past decade. While 49 percent of Republicans and Republican-leaning independents feel “unsympathetic” toward undocumented immigrants, only 13 percent of Democrats and Democrat-leaning independents harbor the same attitude (Pew Research Center 2018).
Despite the politicization of this topic, Hainmueller and Hopkins (2015) find evidence of a consensus on the type of immigrants American prefer. It is unclear, however, whether they have a similar consensual view on immigration policies. To address this, we conduct a conjoint survey experiment (Hainmueller, Hopkins, and Yamamoto 2014) with immigra- tion policy issues currently debated in American politics as attribute-levels. In addition, we include a component of randomized framing treatment in the survey to examine the effects of framing on immigration policy preferences. The survey experiment and its associated analyses provide an understanding as to what form of immigration policy individuals would support, what attributes are salient in this decision, whether framing affects this level of support, and whether preference and the effect of framing differ by the attributes of respondents.
|C2 What are the hypotheses to be tested?||
We aim to test three hypotheses and five research questions (RQs) through a conjoint analysis survey experiment with a randomized assignment of framing treatments.
|C3 How will these hypotheses be tested? *||To test the hypotheses and research questions, we conduct a conjoint analysis survey exper- iment with randomized treatment assignments. We conduct group and sub-group analyses. See the attached for the survey design and plan of statistical analysis.|
