Consumption and precautionary saving : an empirical analysis under both financial and environmental risks

This paper studies the empirical relationship between consumption and saving under two different sources of uncertainty: financial risk and environmental risk. The analysis is carried out using time series data for six advanced economies in the period 1965-2007. The results support the theoretical conclusions that both financial risk alone and the interaction between financial and environmental risks affect consumption. Moreover, we suggest a solution to some shortcomings which concern the empirical analysis performed with one-argument utility functions. Finally, we provide new estimates of indexes of relative risk aversion and relative prudence, and relative preference of environmental quality. -- Consumption ; Precautionary Saving ; Financial Risk ; Environmental Risk ; Prudence ; Relative Risk Aversion ; Uncertainty
