Towards a More General Approach to Testing the Time Additivity Hypothesis, Discussion Paper No 98

Wong, Gary (2001) Towards a More General Approach to Testing the Time Additivity Hypothesis, Discussion Paper No 98. [Working Paper] (Unpublished)



A new procedure is proposed for re-examining the assumption of additivity of preferences over time which, although untenable, is usually maintained in intertemporal analyses of consumption and labour supply. The method is an extension of a famous work by Browning (1991). However, it is more general in permitting the estimation of Frisch demands, which are explicit in an unobservable variable (price of utility), but may lack a closed form representation in terms of observable variables such as prices and total outlay. It also makes an extensive use of duality theory to solve the endogeneity problem encountered in Browning's study. Applying this method with an appropriate estimator to the Australian disaggregate data, we find that the intertemporal additivity hypothesis is decisively rejected, which is consistent with Browning's conclusion. Results also indicate that the effects of lagged and future prices in determining current consumption decisions are insubstantial.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
