Probabilistic techniques were used to characterize dietary exposure of consumers to pesticides found in twelve commodities implicated as having the greatest potential for pesticide residue contamination by a United States-based environmental advocacy group. Estimates of exposures were derived for the ten most frequently detected pesticide residues on each of the twelve commodities based upon re...

This paper provides a framework for establishing the determinacy of equilibria in general equilibrium models with in nitely many commodities and a nite number of consumers and producers. The paper de nes a notion of regular economy for such models and gives su cient conditions on the excess savings equations characterizing equilibria under which regular economies have a nite number of equilibri...

In this paper, we extend the non-cooperative analysis of oligopoly to exchange economies with infinitely many commodities by using strategic market games. This setting can be interpreted as a model of oligopoly with differentiated commodities by using the Hotelling line. We prove the existence of an “active” Cournot-Nash equilibrium and show that, when traders are replicated, the price vector a...

1977) for representing knowledge. About twenty types of event are represented, together with crop-states, weather, commodities, quantities and prices. Frame structures are Interwoven with procedures. COMEX-0 builds frame structures by means of a formal dialogue with a user: Each frame has procedures for requesting information to instantiate its slots. Procedures attached to slots check that res...

We consider the problem of allocating infinitely divisible commodities among a group of agents. Especially, we focus on the case where there are several commodities to be allocated, and agents have continuous, strictly convex, and separable preferences. In this paper, we establish that the uniform rule is the only rule satisfying strategy-proofness, unanimity, symmetry, and nonbossiness.

Salmonella enterica infections are transmitted not only by animal-derived foods but also by vegetables, fruits, and other plant products. To clarify links between Salmonella serotypes and specific foods, we examined the diversity and predominance of food commodities implicated in outbreaks of salmonellosis during 1998-2008. More than 80% of outbreaks caused by serotypes Enteritidis, Heidelberg,...

Sub-Sahara African commodity exporting economies have benefitted greatly from the commodities boom of the past decade. The conventional wisdom argues that resource extraction is corrosive of industrial development due to a combination of the macroeconomic consequences of resource exploitation and the assumed enclave nature of mineral and energy extraction. The paper challenges this pessimistic ...

We describe a board game in which students assume the roles of supply chain enterprises and move game pieces (e.g. Legos, Velcro, etc.) that represent the parts of a basketball hoop. They then assemble these parts and form the final product and sell it to the customers. The game is the first of its kind to illustrate the concepts of shortage gaming, synchronization of the flow of parts, demand ...
