Individual Assignment no. 4

Information aggregation.
Suggest two other business cases in which this method can be used to collect information. What problems do you see besides the ones mentioned in the Background information section? What kind of information system do you need to design to support this method of collecting information? Provide a simple hardware/software configuration.

Answer:
There are a lot of different applications possible for using Information aggregation methods. The ones I found most interesting are:
One of the most interesting economics technologies that has not yet been widely deployed is the information aggregation market (infomart). These markets support open trading on “proposition bets”, wagers on which of two or more outcomes will occur. Such markets can continuously predict the future with more accuracy than opinion polls. The most famous of the infomarts are the Iowa Electronic Markets (IEMs), which trade various kinds of securities. Winner-take-all markets pay $1 for the winning outcome and nothing to losers so the trade price in pennies represents the percent chance the proposition will be true. Vote share markets pay according to the vote share of two or more outcomes. These two types of securities can be used to answer most types of questions. Adopting informarts for space could potentially lead to space colonization years earlier at a far lower total cost than continuing with poor forecasting leading into more blind allies.

Using of Information Aggregation method allowed to discover that: In many controversial areas (eg, affirmative action, campaign finance, sex discrimination, disability discrimination, environmental regulation, and more), Republican appointees show especially conservative voting patterns when they're sitting on 3-judge panels that consist only of Republican appointees. So too for Democratic appointees: They're far more liberal, in their voting patterns, when sitting with two fellow Democratic appointees, than when sitting on a panel with at least one Republican appointee. In other words, Republican appointees look more conservative when they sit only with fellow Republican appointees, and Democratic appointees look more liberal when they sit only with fellow Democratic appointees.
The problems and requirements for this method are complex and they are shown in the pictures below. If the system meets all the requirements below, you can say that the software will work as needed and correct results will be obtained.
















One of the software that can be used is i-Fetch. i-Fetch is a feed reader and information aggregation program that enables you to read various RSS feeds on your desktop, so that you can get information from various sources on a single interface.

Oi, achei seu blog pelo google está bem interessante gostei desse post. Gostaria de falar sobre o CresceNet. O CresceNet é um provedor de internet discada que remunera seus usuários pelo tempo conectado. Exatamente isso que você leu, estão pagando para você conectar. O provedor paga 20 centavos por hora de conexão discada com ligação local para mais de 2100 cidades do Brasil. O CresceNet tem um acelerador de conexão, que deixa sua conexão até 10 vezes mais rápida. Quem utiliza banda larga pode lucrar também, basta se cadastrar no CresceNet e quando for dormir conectar por discada, é possível pagar a ADSL só com o dinheiro da discada. Nos horários de minuto único o gasto com telefone é mínimo e a remuneração do CresceNet generosa. Se você quiser linkar o Cresce.Net(www.provedorcrescenet.com) no seu blog eu ficaria agradecido, até mais e sucesso.

iFetch aggregates information but does not provide incentives to various participants to reveal information.
