We consider a class of additively time-separable life-cycle consumption-savings models with iso-elastic per period power utility featuring resistance to inter-temporal substitution of θ with linear consumption policy functions. The utility maximization problem is dynamically inconsistent for...

Standard economic theory suggests that individuals know best how to make themselves happy. Thus, policies designed to encourage more forward-looking behaviors will only reduce people's happiness. Recently, however, economists have explored the role of impatience, especially difficulties with...

We study the role of expectations of naive agents in a general equilibrium version of the Ramsey model with quasi-hyperbolic discounting. When agents recognize others’ naivete, as strongly suggested by empirical evidence, they revise consumption paths, correctly anticipating prices in a...

I study whether saving behavior reveals socially relevant intertemporal preferences. To this end, I decompose the present generation’s preference for the next into its dynastic and cross-dynastic components in a model of saving. If people are concerned about the next generation as such, then...

In many markets, consumers need to sign advance contracts with upfront fees and usage-based payments. Yet they may value consumptions inconsistently over time. They tend to overconsume temptation goods (e.g., credit cards), but underconsume aversion goods (e.g., gym visits), relative to initial...

Individual’s time preference may be influenced by a variety of factors such as economic conditions. In this paper, we consider the time inconsistent preference triggered by the switches of firm’s profitability state and apply it to the model of dynamic agency and the q theory of investment....

This paper proposes a model of intertemporal preferences where the relative risk aversion depends on the time horizon of the agent. The agent is supposed to evaluate risk in the short run with a relative risk aversion coefficient which differs from its long run value. As preferences are no more...
