Using an ovine model of polycystic ovary syndrome (PCOS), (pregnant ewes injected with testosterone propionate (TP) (100 mg twice weekly) from day (d)62 to d102 of d147 gestation (maternal injection - MI-TP)), we previously reported female offspring with normal glucose tolerance but hyperinsulinemia. We therefore examined insulin signalling and pancreatic morphology in these offspring using qua...

We examine three noncooperative “global warming games” where carbon dioxide emissions and transfers are determined. An international agency implements transfers from rich to poor nations. In each game, the transfer mechanism obeys a predetermined equity principle – horizontal, proportional or “green GNP.” Participation in each transfer scheme is voluntary. We find that implementable horizontal ...

The ecological literature suggests that biodiversity reduces the variance of ecosystem services. Thus, conservative biodiversity management has an insurance value to risk-averse users of ecosystem services. We analyze a conceptual ecological-economic model in which such management measures generate a private benefit and, via ecosystem processes at higher hierarchical levels, a positive external...

Altruism or ‘regard for others’ can encourage self-restraint among generators of negative externalities, thereby mitigating the externality problem. We explore how introducing impure altruism into standard regulatory settings alters regulatory prescriptions. We show that the optimal calibration of both quantitative controls and externality taxes are affected. It also leads to surprising results...

We examine how a shift of bargaining power within households operating in a competitive market environment affects equilibrium allocation and welfare. If price effects are sufficiently small, then typically an individual benefits from an increase of bargaining power, necessarily to the detriment of others. If price effects are drastic the welfare of all household members moves in the same direc...

Congestion externalities may result in non-optimal equilibria. For these to occur, it suffices that facilities differ in their fixed utilities or costs. As this paper shows, the only case in which equilibria are always socially optimal, regardless of the fixed components, in that in which the costs increase logarithmically with the size of the set of users. Therefore, achieving a socially optim...

We report the results of an experiment designed to shed light on beliefs off equilibrium paths. The experiment implements an incomplete information club game. A unique outcome results in all perfect Bayesian equilibria, but beliefs and actions off the equilibrium path are unconstrained under all concepts except extensive form rationalizability (EFR) and logit equilibrium. 90% of subject’s decis...

We study the evolution of preference interdependence in aggregative games which are symmetric with respect to material payo¤s but asymmetric with respect to player objective functions. We identify a class of aggregative games whose equilibria have the property that the players with interdependent preferences (who care not only about their own material payo¤s but also about their payo¤s relative...
