Households’ insurance against shocks to income and asset values (that is, household risk management) is limited, especially for poor households. We argue that a trade-off between intertemporal financing needs and insurance across states explains this basic insurance pattern. In a model with limited enforcement, we show that household risk management is increasing in household net worth and inco...

In the present paper general stationary overlapping generations economies with many commodities in every period and many different consumers in every generation are considered. A government maximizes a utilitarian social welfare function, which is the sum of weighted averages of utilities for generations, through fiscal policy, i.e., monetary transfers and taxes. Situations both with and withou...

We present a model in which two of the most important features of the long-run growth process are reconciled: the massive changes in the structure of production and employment; and the Kaldor facts of economic growth. We assume that households expand their consumption along a hierarchy of needs and firms introduce continuously new products. In equilibrium industries with an expanding and those ...

Does experimental evidence of the common difference effect imply that intertemporal preferences are time inconsistent? Do these features of choice suggest inherent characteristics of preferences, or could they be traced to an underlying factor that shapes the environment? The effect of uncertain lifetime on intertemporal preferences is studied. A demographic model that allows for unobservable h...

Insurance has an intertemporal aspect as insurance premia have to be paid upfront. We argue that the financing aspect of insurance is key to understanding basic insurance patterns. In a model with limited enforcement, we show that insurance is globally monotone increasing in household net worth and income, incomplete, and precautionary. These results hold in economies with income risk, durable ...

We consider lifetime health insurance contracts in which ageing provisions are used to smooth the premium profile. The capital stock accumulated for each individual can be decomposed into two parts: a premium insurance and an annuitised life insurance, only the latter being transferable between insurers without triggering premium changes through risk segmentation. In a simulation based on Germa...

Behavioral economics struggles to explain why people sometimes evaluate outcomes separately (narrow bracketing of mental accounts) and sometimes jointly (broad bracketing). We develop a theory of endogenous bracketing, where people set goals to tackle self-control problems. Goals induce reference points that make substandard performance painful. Evaluating goals in a broadly bracketed mental ac...

In this paper we examine how increases in intertemporal price uncertainty affect the welfare of a consumer. In the preference structure of the consumer the coefficient of relative risk aversion and the elasticity of intertemporal substitution (EIS) are parametrically independent. We find that under empirically plausible circumstances, for each given degree of risk aversion an increase in price ...
