Recent studies of the effects of campaign spendingby political parties and candidates at elections in Canada and elsewherehave established the importance of local constituency campaigns.However, particular claims to measure the effects of campaign spendingon the vote have been questioned on methodological grounds. This articlerevisits the question of whether local spending matters in Canadianfederal elections. Responding to some criticisms of earlier work, thisanalysis presents the results of two parallel regression analyses (thefirst employing two–stage least squares estimation, the secondusing three–stage least squares techniques) of the effects oflocal spending in the 1993 and 1997 elections. The results offer strongconfirmation that comparatively greater local spending by candidatesenhances their vote shares, and diminishes that of rivals, albeit todifferent degrees for different parties and elections.
