We examine self-control problems — modeled as time-inconsistent, presentbiased preferences—in a model where a person must do an activity exactly once. We emphasize two distinctions: Do activities involve immediate costs or immediate rewards, and are people sophisticated or naive about future self-control problems? Naive people procrastinate immediate-cost activities and preproperate—do too soon...

In this paper, we examine whether the imperfections in the credit market spill over to the labor market. We examine the case of a country that experienced a very high degree of imperfections in the financial markets, but underwent substantial changes in 1992 due to the liberalization brought by the European unification and other institutional changes. Italy is therefore a good laboratory to stu...

Kocherlakota and Pistaferri (2007) describe two different models (Private Information Pareto Optimal and Incomplete Markets) of how households partially insure themselves against idiosyncratic shocks. They demonstrate that the models differ in terms of their implications for real exchange rates. In this paper, we use data from a wide range of countries, and document that there is a statististic...

This paper adopts a stochastic overlapping generations framework to analyze the allocation of aggregate financial risks under different social security systems and a majority voting rule. We study whether there will be switches between pay-as-you-go (PAYG) and fully funded (FF) systems in such an economy. We show that in case of a negative aggregate shock, lowincome young individuals will form ...

We provide a lifecycle framework for comparing the insurance value of disability benefits and the incentive cost. We estimate the risks that individuals face and the parameters governing the disability insurance program using longitudinal US data on consumption, health, disability insurance, and wages. We characterize the economic effects of disability insurance and study how policy reforms imp...

This paper analyses the e¤ects of reducing unfunded social security in a closed economy that consists of a service sector and a commodity sector. It is shown that if old agents mainly demand labour intensive services, a modest decrease of the pay-as-you-go pension scheme still raises long-run utility as long as the economy is dynamically e¢cient. However, entirely privatising the social securit...

On average, “young”people underestimate whereas “old”people overestimate their chances to survive into the future. We adopt a Bayesian learning model of ambiguous survival beliefs which replicates these patterns. The model is embedded within a non-expected utility model of life-cycle consumption and saving. Our analysis shows that agents with ambiguous survival beliefs (i) save less than origin...

We perform a structural estimation of the preference parameters in a buffer-stock consumption model augmented with temptation disutility. We adopt a two-stage Method of Simulated Moments methodology to match our simulated moments with those observed in the US Survey of Consumer Finances. To identify the parameters we use liquid and quasi-liquid (retirement) wealth holdings at different ages as ...

We survey over 100 financial planners to assess their reasoning mode, intertemporal choices, risk aversion and preferences, and framing focus. Using the Cognitive Reflection Test, we find that financial planners are more analytical than the general population. Further tests show that the analytical planners are more financially patient and perform better in intertemporal choice problems. These ...

We compare wealth holdings across two cohorts of the Health and Retirement Study: the early Baby Boomers in 2004, and individuals in the same age group in 1992. Levels and patterns of total net worth have changed relatively little over time, though Boomers rely more on housing equity than their predecessors. Most important, planners in both cohorts arrive close to retirement with much higher we...
