Table 3. Effect on Party Vote Shares
Notes: This table presents 2SLS estimates from a panel of 192 constituencies spanning 30 years, focusing on party vote shares. Columns 1-4 display vote shares for Labour, Conservative, regional, and other parties, respectively. Immigration values are based on foreign-born populations from either enfranchised or disenfranchised countries relative to the baseline constituency and are instrumented via the shift-share method (detailed in Section 5.1). KP F stat refers to the Kleibergen-Paap F-stat for the joint significance of the two instruments in the first-stage regression. F-stat (Enf) and F-stat (DisEnf) indicate the Sanderson-Windmeijer partial F-stat for each instrument. Robust standard errors clustered at the constituency level are in parentheses. ***, **, and * indicate significance at the 1, 5, and 10 percent levels.
