Rational beliefs (in the form of WAMS measures) are expectations which though consistent with empirical observations, may deviate from the true underlying probability measure under which data is generated.We provide results on, as well as a decomposition of, WAMS measures and use this to...

This paper provides a general approach in the framework of a complete markets stochastic overlapping generations model to assess whether debt Ponzi schemes are feasible and Pareto-improving. We derive conditions in terms of bond interest rates of different maturities which can be used to assess...

When asset markets are incomplete there are almost always many Pareto improving policy interventions. Remarkably, these interventions do not involve adding any new markets. Focusing on tax policy, I create a framework for proving the existence of Pareto improving taxes, for computing them, and...

Valuation of the benefits from the preservation of water resources is often of interest to policy makers and funding institutions. In developing countries, valuation studies are potentially useful for designing funding policies when inequality is a concern. To fulfil this goal, however,...

We consider competitive bidding for a business license, via an open ascending-price auction, between two symmetric incumbents and a potential entrant, each of whom is privately informed about her own valuation of the license. Entry stands to reduce the payoff of each incumbent below that in...

This paper studies the role of bundling in the efficient provision of excludable public goods. We show that bundling in the provision of unrelated public goods can enhance social welfare. With a large number of goods and agents, first best can be approximated with pure bundling. For a parametric...

According to globalization, certain kinds of public goods, which used to be working as the goods just in a national economy, are getting internationalized or released for foreigners as well. In addition, those goods often exhibit differentiated features for a certain degree. The goods as such...

Microfinance programmes provide poor people with small loans given to jointly liable self-selected groups. Follow-up loans provide incentives to repay. In an experiment we investigate the influence of those features on strategic default. Each group member invests in an individual risky project,...

We conduct an experiment to explore the durability and transferability of the increase in contributions to a public good resulting from the existence of a particular type of implicit informal sanction. Rege and Telle (2003) find that in one-shot games, the sanctioning system leads to high...
