The present paper studies the growth and efficiency consequences of pension funding with individual retirement accounts in a general equilibrium overlapping generations model with idiosyncratic lifespan and labor income uncertainty. We distinguish between economies with rational and hyperbolic...

In the modern welfare state a substantial part of an individual s tax bill is transferred back to the same individual taxpayer in the form of social transfers. This provides a rationale for financing part of social insurance through mandatory savings accounts. We analyze the behavioral and...

This paper studies the design of a nonlinear social security scheme in a society where individuals differ in two respects: productivity and degree of myopia. Myopic individuals may not save enoughʺ for their retirement because their myopic selfʺ emerges when labor supply and savings decisions...

The aging of the populations in the OECD countries has prompted various calls for reforming the existing pay-as-you-go (PAYG) pension systems. Currently, there is renewed discussion in the United States about partial privatization where a fraction of the social security payroll tax would be...

The fluctuations in incomes inherent in rural communities can be attenuated by reciprocal insurance. We develop a model of such insurance based on self-interested behaviour and voluntary participation. One individual assists another only if the costs of so doing are outweighed by the benefits...

The potentially adverse effects of droughts on agricultural output are obvious. Indonesian rice farmers have no financial protection from climate risk via catastrophic weather risk transfer tools. Done well, a weather index insurance (WII) program can not only provide resources that enable...

This study examines the effect of smallholder farmers' access to a formal climate risk transfer mechanism on their risk preferences. Survey and experimental data were collected from smallholder farmers that have access to weather index-based crop insurance (WICI) in Ethiopia. We use an...

We provide novel evidence of how an innovative market-based solution using remote-sensing technology can mitigate conflict. Droughts are a major driver of conflict in Africa, particularly between nomadic pastoralists and sedentary farmers, and climate change is predicted to intensify this...
