This paper compares three models of intertemporal choice concerning saving future lives: the constant discounting model, the proportional discounting model and the hyperbolic discounting model. The three models were investigated using data collected from the general public. Since these data have a multilevel structure, ordinary least-squares (OLS) estimates were supplemented by multilevel analysis. There is evidence in favour of the proportional (and to a lesser extent) the hyperbolic model over the constant discounting model. There is clear evidence for this data set that multilevel analysis is more appropriate than OLS.
