Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...

An in-kind subsidy is equivalent, both theoretically and empirically, to an increase of income for an individual consumer. But the equivalence does not empirically carry over to in-kind grants by a central government to a local one: this has been seen as an anomaly and dubbed the â??flypaper...

Various experimental procedures aimed at measuring individual risk aversion involve a list of pairs of alternative prospects. We first study the widely used method by Holt and Laury (2002), for which we find that the removal of some items from the lists yields a systematic decrease in risk...

Sustainability has been largely replaced by discounted utilitarianism in contemporary climate-change economics. Our approach rejuvenates sustainability by expanding the conception of the quality of life, along the lines of the UN Human Development Reports, to include not only consumption, but...

Let there be a positive (exogenous) probability that, at each date, the human species will disappear. We postulate an Ethical Observer (EO) who maximizes intertemporal welfare under this uncertainty, with expected-utility preferences. Various social welfare criteria entail alternative von...

Climate stabilization requires low GHG emissions. Is this consistent with nondecreasing human welfare? Our welfare index, called quality of life (QuoL), emphasizes education, knowledge, and the environment. We calibrate a multigenerational model with education, physical capital, knowledge and...

How should the benefits of the commons, say a publicly owned fishing resource, be distributed? A first possibility is equal division among the population. A second option is to distribute them among the people who actually exploit the resource in proportion to their activity level: this is the...

Our work attempts to investigate the influence of credit tightness or expansion on activity and prices in a multimarket set-up. We report on some doubleauction, two-market experiments where subjects had to satisfy an inequality involving the use of credit. The experiments display two regimes....

The quasilinearity assumption (informally speaking, the assumption that utility is linear in the numeraire good, or that income effects are absent from the demand of nonnumeraire goods) makes surplus analysis exact in economies where all agents are contemporaneous. Efficiency is then eqivalent...

How can one tell whether academic research influences macroeconomic policy? One possibility is to look at government documents that set forth macro policy. This paper looks for such traces in U.S., European and Japanese documents. Because of ease of access it focuses on U.S. documents. Numerous...
