Book Description
This paper employs a synthetic cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of optimal life-cycle consumption expenditures in the presence of realistic labor income uncertainty. The model fits the profiles quite well. In addition to providing tight estimates of the discount rate and risk aversion, we find that consumer behavior changes strikingly over the life-cycle. Young consumers behave as buffer-stock agents. Around age 40, the typical household starts accumulating liquid assets for retirement, and its behavior mimics more closely that of a certainty equivalent consumer. This change in behavior is mostly driven by the life-cycle profile of expected income. Our methodology provides a natural decomposition of saving into its precautionary and retirement components.

Book Description
The past decade has witnessed a decline in saving throughout the developed world—the United States has the dubious distinction of leading the way. The consequences can be serious. For individuals, their own economic security and that of their families is jeopardized. For society, inadequate rates of saving have been blamed for a variety of ills—decreasing the competitive abilities of American industry, slowing capital accumulation, increasing our trade deficit, and forcing the sale of capital stock to foreign investors at bargain prices. Restoring acceptable rates of saving in the United States poses a major challenge to those who formulate national economic policy, especially since economists and policymakers alike still understand little about what motivates people to save. In National Saving and Economic Performance, edited by B. Douglas Bernheim and John B. Shoven, that task is addressed by offering the results of new research, with recommendations for policies aimed to improve saving. Leading experts in diverse fields of economics debate the need for more accurate measurement of official saving data; examine how corporate decisions to retain or distribute earnings affect household-level consumption and saving; and investigate the effects of taxation on saving behavior, correlations between national saving and international investment over time, and the influence of economic growth on saving. Presenting the most comprehensive and up-to-date research on saving, this volume will benefit both academic and government economists.

Book Description
The main aim of this paper is to assess the validity of the life cycle model of consumption. In particular, we address an issue that has recently received much attention, especially in the macroeconomic literature: that of "excess sensitivity" of consumption growth to income growth. We do this using a time series of cross sections and a novel and flexible parameterization of preferences. The former allows us to' address aggregation issues directly, while with the latter we can allow both the discount factor and the elasticity of intertemporal substitution eis to be affected by various observable variables and lifetime wealth. The main findings can be summarized as follows: (i) the excess sensitivity of consumption growth to labor income disappears when we control for demographic variables. This is true both at life cycle and business cycle frequencies. (ii) estimation of a flexible specification of preferences indicates that the elasticity of intertemporal substitution is a function of several variables, including the level of consumption. The eis increases with the level of consumption, as expected. (iii) the variables that change the eis are also important in explaining why we observe excess sensitivity over the business cycle. (iv) we are able to reconcile our results with those reported both in the macro and micro literature. (v) in our specification the elasticity of intertemporal substitution is not very well determined. This result, however, should be taken with care, as we have not made an effort to construct a 'preferred' specification, which would probably include additional controls for labor supply behavior. The evidence presented shows that the life cycle model cannot be easily dismissed. Indeed, we believe that the model does a good job at representing consumption behavior both over the life cycle and over the business cycle.

Book Description
This paper uses a seminonparametric model and Consumer Expenditure Survey data to estimate life cycle profiles of consumption, controlling for demographics, cohort and time e.ects. In addition to documenting profiles for total and nondurable consumption, we devote special attention to the age expenditure pattern for consumer durables. We find hump-shaped paths over the life cycle for total, for nondurable and for durable expenditures. Changes in household size account for roughly half of these humps. The other half remains unaccounted for by the standard complete markets life cycle model. Our results imply that households do not smooth consumption over their lifetimes. This is especially true for services from consumer durables. Bootstrap simulations suggest that our empirical estimates are tight and sensitivity analysis indicates that the computed profiles are robust to a large number of different specifications

Book Description
"We explore the quantitative implications of uncertainty about the length of life and a lack of annuity markets for life cycle consumption in a general equilibrium overlapping generations model in which markets are otherwise complete. Empirical studies find that consumption tends to rise early in life, peak around age 45-55, and to decline after that. Our calibrated model exhibits life cycle consumption that is consistent with this pattern. This follows from the fact that, due to a lack of annuity markets, households discount the future more heavily as they age and their probability of survival falls. Once an unfunded social security system is introduced, the profile is still hump shaped, but the decline in consumption does not begin until after retirement in our base case. Adding a bequest motive causes this decline to begin at a younger age"--National Bureau of Economic Research web site.
