Neoclassical economic theory rules out systematic errors in consumption choice. According to the basic view, individuals know what they choose. They are able to predict how much utility an activity or a good produces for them now and in the future and they can maximize their utility. This...

Western governments are currently contemplating how to adapt their Pay-As-You-Go pension systems so that these remain financially sustainable, even with an aged population. To the extent that policy-makers haven't already adapted their old age social security schemes, an ageing population thus...

This paper considers the relationship between the economic concept of time preference and relevant concepts from psychology and biology. Using novel data from a time diary study conducted in Ireland that combined detailed psychometric testing with medical testing and real-time bio-tracking, we...

While commitment devices such as defaults and direct deposits from wages have been found to be highly effective to increase savings, they are unavailable to the millions of people worldwide who not have a formal wage bill. Self-help peer groups are an alternative commitment device that is...

The existing literature suggests that when the saving decision of two-earner households under risk is analysed, standard results on the existence of precautionary saving no longer apply: precautionary saving is obtained if and only if very stringent conditions hold. This paper shows that when...

Some individuals borrow extensively on their credit cards. This paper tests whether present-biased time preferences correlate with credit card borrowing. In a field study, we elicit individual time preferences with incentivized choice experiments, and match resulting time preference measures to...

Household credit, especially for mortgages, has doubled over the past years in the new European Union member countries, raising concerns about the economic and social consequences of household indebtedness in the event of a macroeconomic crisis. Using household survey data for 2005, 2006, and...

One suggested hypothesis for the dramatic rise in household borrowing that preceded the financial crisis is that low-income households increased their demand for credit to finance higher consumption expenditures in order to "keep up" with higherincome households. Using household level data on...

In a simple conceptual framework, we organize a multitude of phenomena related to the (mis)prediction of utility. Consequences in terms of distorted choices and lower wellbeing emerge if people have to trade-off between alternatives that are characterized by attributes satisfying extrinsic...
