Limited liability and asymmetric information between an investment bank and its lenders provide an incentive for a bank to undercapitalise and finance overly risky business projects. To counter this market failure, national governments have imposed solvency constraints on banks. However, these...

When information on longevity (survival functions) is unknown early in life, individuals have an interest to insure themselves against future "risk-class" classification. Accordingly, the First-Best typically involves transfers across states of nature. Competitive equilibrium cannot provide such...

The last decade has seen the burgeoning of several hundred local community currency institutions in cities across the world. Although residents of these communities claim that local currency promotes local development, how if at all it does so has hitherto been unexplored. This paper argues that...

Voluntary public unemployment systems are limited to a handful of countries, including Finland, Sweden, and, more substantially, Denmark. A voluntary system has the positive feature of other user-cost schemes, potentially efficient targeting of services. This presumes rational behavior as well...

This informal paper explores models of competitive insurance market equilibrium when individuals of initially similar apparent risk experience divergence in risk levels over time. The information structure is modeled in three alternative ways: all insurers and insureds know risk at any point in...

In the expected-utility theory of the monetary value of a statistical life, the so-called dead-anyway effect discovered by Pratt and Zeckhauser (1996) asserts that an individuals' willingness to pay (WTP) for small reductions in mortality risk increases with the initial level of risk. Their...

The new information and communication technology, ICT, induces households to take over tasks from firms and government agencies, using tools and systems provided by these very same organizations. The result is often joint production activities. We argue that the importance of ICT for the...

It is well recognised that the issue of the social rate of discount applies only to the gains from public investment that accrues to the public sector. When it comes to measurement, however, there is a problem: public investment in infrastructure and the like do not usually yield direct...

The paper offers a proof that expected utility maximisation with logarithmic utility is a dominant preference in the biological selection process in the sense that a population following any other preference for decision-making under risk will, with a probability that approaches certainty,...

According to many observers, the world is currently getting riskier along many of its dimensions. In this paper we analyse how the welfare state, i.e., social insurance that works through redistributive taxation, should deal with this trend. We distinguish between risks that can be insured by...
