Sophisticated agents with self-control problems value commitment devices that constrain future choices. Using Australian household data, I test whether these households value commitment devices in the form of illiquid pension contributions. Applying various probabilistic choice models, the...

This paper investigates whether the inclusion of housing in a household portfolio is important to the household’s intertemporal decision making. Households hold portfolios of assets rather than a Treasury bill and/or a stock index and make their spending decisions based on expected total...

This paper investigates whether the rate of interest such as the Treasury bill rate or the rate of return such as the return on a household portfolio is more relevant to the household’s intertemporal decision making. In a current era, households are diversifiers (to use Tobin’s 1958 term)...

We propose that asset accumulation occurs in three stages. In the first stage (reallocation), current resource inflows must exceed current outflows. To meet this objective, people reallocate resources from current consumption, current leisure, or future consumption or leisure. In the second...

Attempts to gauge the depth of outreach of microfinance organizations usually start--and often end--with the measurement of loan size. But just what is loan size? Loan size has at least seven aspects, each of which matters not only for depth of outreach but also for profitability. The aspects...

We investigate the role that self-control problems modeled as time-inconsistent, present-biased preferences and a person's awareness of those problems might play in leading people to develop and maintain harmful addictions. Present-biased preferences create a tendency to over-consume addictive...

Microfinance—both credit and savings—has potential to improve the well- being of poor women in developing countries. This paper explores practical ways to achieve that potential. Based on lessons from informal saving mechanisms that women already use, the paper proposes two savings services...

Households in developing countries use a variety of informal mechanisms to cope with risk, including mutual support and risk-sharing. These mechanisms cannot avoid that they remain vulnerable to shocks. Public programs in the form of food aid distribution and food-for-work programs are meant to...

We apply the set up of limited commitment model to empirically test the role of informal risk-sharing networks using panel data on informal credit transactions from rural Ethiopia. The empirical estimates provide convincing evidence for the belief that enforcement problem limits the direct role...

People underappreciate how their own behavior and exogenous factors affect their future utility, and thus exaggerate the degree to which their future preferences resemble their current preferences. We present evidence which demonstrates the prevalence of such projection bias, and develop a...
