When territory matters: parliamentary profiles and legislative behaviour in Italy (1987–2008)

This paper ponders the question of whether Members of Parliaments' (MPs) previous experiences and personal attributes may have any impact on the way they behave once elected. In agreement with a recent stream of literature, the authors hypothesise that MPs with strong territorial roots might behave as agents of the local community, promoting its interests and demands in their parliamentary activity. The assertion that individual biographies influence legislative activity in parliamentary democracies runs counter to the commonly held view that in this kind of institutional setting, legislative assemblies are dominated by parties, leaving little room for individually oriented behaviour and little incentive to do anything that is not coordinated by party organisations. The article builds an original 'index of localness', the main independent variable, based on the place of birth and previous political experience at local level of MPs. Then, taking into account territorially targeted Private Members' Bills as a proxy for the territorial behaviour of each legislator, the hypothesis is tested by looking at both aggregate evidence and individual-level data. Aggregate data support the hypothesis, as they show a monotonically increasing relationship between the two variables: the more a legislator is linked to his/her territory, the more (on average) he/she will sponsor bills concerning the local area. Individual-level data confirm this finding, as the correlation between the two variables also holds when entering a number of control variable
