Reinforcement Learning and Savings Behavior

We show that individual investors over‐extrapolate from their personal experience when making savings decisions. Investors who experience particularly rewarding outcomes from 401(k) saving—a high average and/or low variance return—increase their 401(k) savings rate more than investors who have less rewarding experiences. This finding is not driven by aggregate time‐series shocks, income effects, rational learning about investing skill, investor fixed effects, or time‐varying investor‐level heterogeneity that is correlated with portfolio allocations to stock, bond, and cash asset classes. We discuss implications for the equity premium puzzle and interventions aimed at improving household financial outcomes.     

Pension reforms and saving gains in the United Kingdom

The empirical validity of the effect of pension reforms on domestic savings in the UK has been investigated using an Auto‐regressive Distributed Lag (ARDL) model capable of testing for the existence of a long‐run relationship regardless of whether the underlying time series are individually I(1) or I(0). The total savings response to change in pension savings is positive and significant, but an increase in occupational pension saving appears offset by a decrease in other forms of saving. This paper concludes that there is no firm evidence that aggregate savings increase considerably because of privately funded pension schemes.     

The Effect of Providing Peer Information on Retirement Savings Decisions

Using a field experiment in a 401(k) plan, we measure the effect of disseminating information about peer behavior on savings. Low‐saving employees received simplified plan enrollment or contribution increase forms. A randomized subset of forms stated the fraction of age‐matched coworkers participating in the plan or age‐matched participants contributing at least 6% of pay to the plan. We document an oppositional reaction: the presence of peer information decreased the savings of nonparticipants who were ineligible for 401(k) automatic enrollment, and higher observed peer savings rates also decreased savings. Discouragement from upward social comparisons seems to drive this reaction.     

How best to link poverty reduction and debt sustainability in IMF–World Bank models?

This paper attempts to provide an economic model in the context of developing countries to address the policy strategies related to poverty reduction. With a view to deal with the shortcomings of the existing approaches as regards poverty reduction, this paper develops a model on the basis of the policy framework of the IMF and the World Bank to show how demand growth can be a crucial mechanism in determining the potential rate of growth, and then to suggest ways in which poverty—conceptualised officially in absolute terms with a subjective cut‐off point (e.g. US $1/$2 a day), and a new objective measure in terms of consumption deprivation—can be linked with the key policy variables contained in the adjustment programmes. A strategy of investment in infrastructure and in human development, and improving access to credit markets, particularly in rural areas to encourage or ‘crowd in’ private investment is a precondition for growth and poverty alleviation. Debt relief can only provide a temporary, not a sustainable, solution to the problem of reducing poverty.
