INP: Party Nationalization Index (INP)

Description

Jones and Mainwaring (2003), proposed the calculation of this index based on the Gini income concentration index. This index will take values between 0 and 1. A value close to 1 indicates that the party is highly nationalized, and a value close to zero will indicate the opposite.

This index measures the degree of homogeneity of the votes a party receives in all the electoral districts where it competes. In a very brief way, the calculation formula for this indicator is as follows:

$$IPN=1- Gini coefficient$$

Usage

INP(dat)

Arguments

dat

Vector containing the proportions (as parts per unit) of the party's vote in each district

Value

A real number containing the value of the indicator.
