Australian employers are obliged by law to make a minimum compulsory contribution as a proportion of salaries into employees’ superannuation (pension) funds. Individuals can also make voluntary contributions on top of the compulsory amount. We examine voluntary contributions amongst two groups...

We test for causality between radiative forcing and temperature using multivariate time series models and Granger causality tests that are robust to the non-stationary (trending) nature of global climate data. We find that both natural and anthropogenic forcings cause temperature change and also...

The degree of substitutability assumed between inputs in production and commodities in consumption is one of the key factors that might affect the range of predicted climate mitigation costs. We explore how and by how much assumptions about elasticities of substitution affect estimates of the...
