Analysis and selection of the simulation environment

This document provides the initial report of the Simulation work package (Work Package 4,WP4) of the CATNETS project. It contains an analisys of the requirements for a simulation tool to be used in CATNETS and an evaluation of a number of grid and general purpose simulators with respect to the selected requirements. A reasoned choice of a suitable simulator is performed based on the evaluation conducted. -- Diese Arbeit analysiert die Anforderungen an eine Simulationsumgebung für die Analyse der Katallaxie.

What's that got to do with the price of fish? Buyers behavior on the Ancona fish market

In this paper we analyze the Ancona wholesale fish market (MERITAN) where transactions take place in three simultaneous Dutch auctions. Our objective is to characterize the behavior of market participants and, in particular, buyers in such a market structure. Our analysis of the data shows that buyer-seller relationships are less important than in a pairwise bargaining market such as the Marseille Fish market but that a significant amount of “loyalty" is still present under the auction mechanism. We provide an explanation of the “declining price paradox" for the fish market of Ancona by linking the rule used by the buyers to set their bid to the relationship between the variation in the price of the last transactions in the day and the quantity of fish available on that day. In fact, the average price tends to increase for last transactions on days characterized by limited supply of fish.wholesale fish market; Dutch auction

Evaluation and metrics framework

In this paper a metrics framework for evaluating different scenarios in the CATNETS project is defined. The aim is to use this framework to compare the catallactic scenario against the central auctioneer. --Grid Computing

Analysis of simulation environment

In this paper the requirements for an ALN simulation environment are analysed, as needed in the CATNETS Project. A number of grid and general purpose simulators are evaluated regarding the identified requirements for simulating economical resource allocation mechanisms in ALNs. Subsequently a suitable simulator is chosen for usage in the CATNETS project. --CATNETS simulator,requirements analysis,simulator selection

a novel computational model of the wheat global market with an application to the 2010 russian federation case

In this paper, we build a computational model for the analysis of international wheat spot price formation, its dynamics and the dynamics of quantities traded internationally. The model has been calibrated using FAOSTAT data to evaluate its in-sample predictive power. The model is able to generate wheat prices in twelve international markets and traded wheat quantities in twenty-four world regions. The time span considered is from 1992 to 2013. In our study, particular attention was paid to the impact of the Russian Federation's 2010 grain export ban on wheat price and quantities traded internationally. Among other results, we found that the average weighted world wheat price in 2013 would have been 3.55% lower than the observed one if the Russian Federation had not imposed the export ban in 2010
