Life Cycle: Consumption, Consumer Income and Savings

  • Chapter
  • First Online:
Consumer Demographics and Behaviour

Abstract

The sixth chapter examines how consumption per capita tends to track income per capita across countries and within individual countries with diverse income levels and cultures. It discusses the Life-Cycle Hypothesis concerned with the maximisation of consumption during the life-cycle. It also illustrates life-cycle hump-shaped trends. It raises conceptual and measurement issues including household-size equivalence measures. These issues include the question of cross-sectional findings and longitudinal trends and the use of pseudo panels. It examines issues related to consumption and savings in old age and differential mortality. It then reviews empirical findings related to household size, employment, work-related expenditures, durable and non-durable goods related to consumer behaviour. Finally, it assesses factors affecting consumer behaviour in retirement, a growing demographic trend, including credit/liquidity constraints, income and life expectancy uncertainty, bequest motives, leisure choices and unanticipated shocks.

Notes

  1. 1.

    The few outliers in Fig. 6.1 are usually small countries with special characteristics such as Macau (China) or oil-producing countries in the Middle East.

  2. 2.

    A considered review of some theoretical and measurement issues of consumer behaviour is contained in Richard Blundell’s article “Consumer Behaviour: Theory and Empirical Evidence – A Survey” in The Economic Journal, 98 (March 1988): 16–65.

  3. 3.

    OECD is the Organization for Economic Co-operation and Development

  4. 4.

    These are the results of analysis undertaken by the authors of Australian household expenditure. The adjusted regression coefficient was 0.547. The way in which durable goods and business-expense allowances were handled in the survey made consistency difficult to achieve.
