Hyperbolic discounting (H) is currently the dominant behavioral model of intertemporal choice, since it better explains how people behave than the normatively correct exponential discounting model (E). This paper promotes an arithmetic discounting model (A) which challenges H. First, A is more...

We propose a model of parental altruism in relation with child habit formation, where children are unaware of their developing habits while young, and become cognizant of them only on growing up. We show that an altruistic mother (i) maintains the amount of income transferred to her child lower...

We study whether and how parents interfere paternalistically in their children's intertemporal decision-making. Based on experiments with over 2,000 members of 610 families, we find that parents anticipate their children's present bias and aim to mitigate it. Using a novel method to measure...

Endogenous time discounting is introduced in a two-period human-capital-driven growth model: subjective discount rate depends upon the level of human capital. This assumption accords strongly with the micro-level evidence. In the model an individual optimizes consumption over two periods. Low...

What is an optimal or a sustainable external debt - for a country, region or sector? How should one monitor and evaluate debt to preclude a crisis? We use stochastic optimal control/dynamic programming to derive an optimal debt. The deviation of the actual from the optimal will serve as a...

We exploit the fact that Israeli pension insurance policies do not take health conditions or smoking status into account in annuity pricing to investigate the potential effect of being a smoker on retirement payout choices. Contrary to the idea that smokers have higher discount rates (and thus...
