Case Selection

Australia and New Zealand share a similar social and political history, and importantly, the rate of private health insurance coverage in Australia prior to the introduction of the PHIIS (30.1% coverage) was similar to the current rate seen in New Zealand (30% coverage) (Business Desk, 2012, May 23; Harley, Vaithianathan, Crossley & Cobb-Clark, 2002). The case selection technique is then in line with a ‘most similar’ case selection technique as presented by Seawright and Gerring (2008) which allows for the isolation of the variable of interest; the PHIIS.
