We use the Italian Survey of Household Income and Wealth, a rather unique dataset with a long time dimension of panel information on consumption, income and wealth, to structurally estimate a buffer-stock saving model. We exploit the information contained in the joint dynamics of income,...

When the financial positions of pension funds worsen, regulations prescribe that pension funds reduce the gap between their assets (invested contributions) and their liabilities (accumulated pension promises). This paper quantifies the business cycle effects and distributional implications of...

In this paper I discuss overweight and obesity and their repercussions on health deficit accumulation and longevity in a life cycle model. Individual decisions are conceptualized as the partial control of impulsive desires of a short-run self (the limbic system) by a rationally forward-looking...

We use administrative and survey-based micro data to study the relationship between cognitive abilities (IQ), the formation of economic expectations, and the choices of a representative male population. Men above the median IQ (high-IQ men) display 50% lower forecast errors for inflation than...

Intertemporal substitution is at the heart of modern macroeconomics and finance as well as economic policymaking, but a large fraction of a representative population of men - those below the top of the distribution by cognitive abilities (IQ) - do not change their consumption propensities with...

A precautionary saving model is extended to include old-age pensions and provides the framework for an empirical analysis of the relation between old-age pensions and private consumption. Norwegian macro-data for socioeconomic groups of households are used to estimate consumption functions for...

The present paper uses the model by Campbell and Mankiw (1991) to examine the Norwegian consumer behavior and the role of the financial deregulation during the 1980s. For quarterly data on non-durables and services, we estimate the fraction of current income consumers to be in the range of 37%...

I use new micro data to study the effects of credit deregulation on the Norwegian household savings decline in the mid-1980s. This paper has three main findings. First, the decline in saving started in 1983, a couple of years earlier than previously thought on the basis of National Accounts...

Differences in individual wealth holdings are widely viewed as a driving force of economic inequality. However, as this finding relies on cross-section data, we may confuse older with wealthier. We propose a new method to adjust for age effects in cross-sections, which eliminates transitory...

The paper explores how repeated revisions of consumption plans increase long-run utility. If agents value present anticipations of future consumption, some revisions may be viewed as a benign form of self-delusion. We consider a minimal generalization of the Samuelson discounted utility model to...
