There is widespread agreement that given currently available data, we cannot accurately estimate the parameters of intertemporal allocation using GMM on Euler equations, whether they be exact or approximate. Our reading of this literature and our own results is that this is a small sample...

We develop a framework in which: (i) a firm can have a new product tested publicly before launch; and (ii) tests vary in toughness, holding expertise fixed.  Price flexibility boosts the strong positive impact on consumer beliefs of passing a tough test and mitigates the strong negative impact...

In the past 30 years, microfinance has carried many promises of social and economic transformation, with the shift towards targeting women being seen as a major strategic move through which the promise of social development could be most effectively delivered.  However, ethnographic studies...

A generalized version of the capital management problem posed in a classic paper by R.H. Strotz is analyzed for the case of the naive planner who fails to anticipate any impending change in his own preferences. By imposing progressively stronger restrictions on the primitive of the problem -...

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 ntworks 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...

We study the effect of hyperbolic discounting on competitive equilibria in secondary markets for a durable good. Under exponential discounting, secondary markets are irrelevant in our model. They do not affect the price in the initial period and are neutral to the allocation. Under hyperbolic...

The principles of how best to manage the various components of national wealth are outlined, where the permanent income hypothesis, the Hotelling rule and the Hartwick rule play a prominent role. As far as managing natural resource wealth is concerned, a case is made to use an intergenerational...

Counselling agencies assist borrowers in financial difficulties by administering repayment plans, the so-called debt management plans (DMPs).  In this paper, we use unique administrative data from a major credit counselling agency in the UK to analyze the determinants of debt repayment...
