Conceptualizing and Measuring Immigration Policies: The Immigration Policies in Comparison (IMPIC) Index

It will open a completely new research field and allow researchers to study the causes and effects of immigration policies and developments across time more systematically. Contrary to existing indices this index will be conceptually more comprehensive and distinguish between (1) all relevant policy fields, (2) regulations that create/constrain rights and control mechanisms, (3) external regulations that concern border crossing and thus eligibility criteria and conditions and internal regulations that concern the status and rights of immigrants.
