Última A model-based approach to moral hazard in food chains - What contribution do principal-agent-models make to the understanding of food risks induced by opportunistic behaviour? AgEcon Hirschauer, Norbert. Food risks may be caused by moral hazard, i.e. by opportunistic behaviour of upstream sellers who exploit the fact that many food product qualities remain uncertain to downstream buyers in the course of conventional market transactions (credence qualities). Due to this lack of market transparency buyers run the risk to pay premium prices for inferior products (quality risks); furthermore, they run the risk to use or consume substances which are harmful (health risks). Therefore, they will want to design optimal contracts and controls preventing opportunistic behaviour. Usually, however, buyers cannot contract contingent on the actions of upstream sellers because they cannot observe them directly (information asymmetry). Motivated by the obviously...

Ano: 2004 URL: http://purl.umn.edu/97448 What coatis and mongooses have in common? Biota Neotropica Sazima,Ivan. The coatis (Procyonidae) and some species of mongooses (Herpestidae) are diurnal, small to medium-sized carnivores that live in groups and feed opportunistically on small animals and fruits. A comparison of selected features is here presented for two coati species (Nasua narica and N. nasua) and the banded mongoose (Mungos mungo). The former two dwell in the Neotropical region, whereas the latter occurs in the Ethiopian realm. Both the coatis and the mongoose are apt to live near human settlements and capitalise on food refuse. Additionally, coatis and mongooses habituate to humans, and sometimes are a nuisance. These habits, plus their almost constant quest for food, lead these carnivores to meet other mammal types at feeders and garbage dumps and...
