ANN based day-ahead spinning reserve forecast for electricity market simulation

Electricity market players operating in a liberalized environment require adequate decision support tools, allowing them to consider all the business opportunities and take strategic decisions. Ancillary services represent a good negotiation opportunity that must be considered by market players. This paper deals with short-term predication of day-ahead spinning reserve (SR) requirement that helps the ISO to make effective and timely decisions. Based on these forecasted information, market participants can use strategic bidding for day-ahead SR market. The proposed concepts and methodologies are implemented in MASCEM, a multi-agent based electricity market simulator. A case study based on California ISO (CAISO) data is included; the forecasted results are presented and compared with CAISO published forecast.

Market Transparency, Market Quality and Sunshine Trading

This paper analyzes the implications of pre-trade transpareny on market performance. We find that transparency increases the precision held by agents, however we show that this increase in precision may not be due to prices themselves. In competitive markets, transparency increases market liquidity and reduces price volatility, whereas these results may not hold under imperfect competition. More importantly, market depth and volatility might be positively related with proper priors. Moreover, we study the incentives for liquidity traders to engage in sunshine trading. We obtain that the choice of sunshine/dark trading for a noise trader is independent of his order size, being the traders with higher liquidity needs more interested in sunshine trading, as long as this practice is desirable. Key words: Market Microstructure, Transparency, Prior Information, Market Quality, Sunshine Trading

Consumers' attitudes, trust and willingness to pay for food information

Market failure can be corrected using different regulatory approaches ranging from high to low intervention. Recently, classic regulations have been criticized as costly and economically irrational and thus policy makers are giving more consideration to soft regulatory techniques such as information remedies. However, despite the plethora of food information conveyed by different media there appears to be a lack of studies exploring how consumers evaluate this information and how trust towards publishers influence their choices for food information. In order to fill such a gap, this study investigates questions related to topics which are more relevant to consumers, who should disseminate trustful food information, and how communication should be conveyed and segmented. Primary data were collected both through qualitative (in depth interviews and focus groups) and quantitative research (web and mail surveys). Attitudes, willingness to pay for food information and trust towards public and private sources conveying information through a new food magazine were assessed using both multivariate statistical methods and econometric analysis. The study shows that consumer attitudes towards food information topics can be summarized along three cognitive-affective dimensions: the agro-food system, enjoyment and wellness. Information related to health risks caused by nutritional disorders and food safety issues caused by bacteria and chemical substances is the most important for about 90% of respondents. Food information related to regulations and traditions is also considered important for more than two thirds of respondents, while information about food production and processing techniques, life style and food fads are considered less important by the majority of respondents. Trust towards food information disseminated by public bodies is higher than that observed for private bodies. This behavior directly affects willingness to pay (WTP) for food information provided by public and private publishers when markets are shocked by a food safety incident. WTP for consumer association (€ 1.80) and the European Food Safety Authority (€ 1.30) are higher than WTP for the independent and food industry publishers which cluster around zero euro. Furthermore, trust towards the type of publisher also plays a key role in food information market segmentation together with socio-demographic and economic variables such as gender, age, presence of children and income. These findings invite policy makers to reflect on the possibility of using information remedies conveyed using trusted sources of information to specific segments of consumers as an interesting soft alternative to the classic way of regulating modern food markets.

What Does the Market Learn from Stock Offering Revisions?

We examine the disclosure of size revisions of seasoned stock offerings to see what information revisions impart to investros. Revisions could deliver firm-originated infoirmation, which discloses something managers know about the firm. Alternatively, they could disseminate market-originated information, which is information market participants have but which is not conveyed until trading takes place. Our results reject the notion that revisions reveal firm-originated news. Instead, the results are consistent with the market-originated news hypothesis and suggest a mechanism that investros and underwriters use to learn about the demand for an offering.

The Staple Commodities of the Knowledge Market

In this paper, the “Information Market” is introduced as a payable information exchange and based on it information interaction. In addition, special kind of Information Markets - the Knowledge Markets are outlined. The main focus of the paper is concentrated on the investigation of the staple commodities of the knowledge markets. They are introduced as kind of information objects, called “knowledge information objects”. The main theirs distinctive characteristic is that they contain information models, which concern sets of information models and interconnections between them.

An interactive state monad example

A common problem among information systems is the storage and maintenance of permanent information identified by a key. Such systems are typically known as data base engines or simply as data bases. Today the systems information market is full of solutions that provide mass storage capacities implemented in different operating system and with great amounts of extra functionalities. In this paper we will focus on the formal high level specification of data base systems in the Haskell language. We begin by introducing a high level view of a data base system with a specification of the most common operations in a functional point of view. We then augment this specification by lifting to the state monad which is then modified once again to permit input/output operations between the computations

Os fundos éticos nos mercados nas Bolsas de Valores

É possível encontrar nos mercados de valores mobiliários e/ou outros instrumentos financeiros e/ou nas chamadas bolsas de valores - éticas concretas, reais e definidas? Pensamos que sim. Os fundos éticos são apenas uma das espécies de fundos. Abstract: You can find in the securities markets and / or other financial instruments and / or in so-called exchanges - concrete ethical, real and defined? We think so. Ethical funds are only one species of funds.

Media, investors and bubbles

We analysed the specific case of how information in the financial press influences economic bubbles. We found considerable flaws in the information market due to several factors: demand, the predominance of what are termed “irrational investors” (herding), and supply, which has the problem that the sources of information are biasedand feeds. A financial bubble is a deviation between real value of a financial asset and its persistent market price in time, which also has a speculative origin fed back by the illusion of the owners of these financial values, who will take benefits because of the future prices, which must be higher than the previous ones. The economical information in the media is submitting three problems. First of all, it is information generated by companies. In second place, the information circuit is fed back. A problem of informative independence becomes created, particularly serious in the case of the banks, which are very were as creditors. And in a third place, some informative biases are manifested for the companies of regulated sectors which are starring the economical information in the media.

Gérer la ville au Bénin : la mise en œuvre du Registre foncier urbain à Cotonou, Porto-Novo et Bohicon

La gestion des villes d’Afrique de l’Ouest pose problème à la période contemporaine : extension urbaine non maitrisée, services de base insuffisants, insécurité foncière. À travers l’aide internationale, d’importantes réformes visant à améliorer son efficacité ont pourtant été mises en place, mais elles semblent avoir été inefficaces. Dépassant ce constat d’échec, la thèse vise à comprendre comment se déroule l’acte de gérer la ville dans les circonstances particulières des villes d’Afrique de l’Ouest. La mise en œuvre du Registre foncier urbain (RFU), système d’information foncière municipal multi-fonctions introduit au Bénin à travers des programmes de développement au début des années 1990, constitue le prisme à travers lequel la gestion urbaine est analysée. Celle-ci est ainsi approchée par les actes plutôt que par les discours. S’appuyant sur une démarche socio-anthropologique, la mise en œuvre de l’instrument est analysée depuis le point de vue des acteurs locaux et selon une double grille de lecture : d’une part, il s’agit de saisir les logiques de l’appropriation locale dont le RFU a fait l’objet au sein des administrations; d’autre part, il s’agit de comprendre son interaction avec le territoire, notamment avec les dynamiques complexes d’accès au sol et de sécurisation foncière. Une étude de cas multiple a été menée dans trois communes : Cotonou, Porto-Novo et Bohicon. Deux ensembles de conclusions en découlent. Tout d’abord, le RFU s’est imposé comme l’instrument pivot de la fiscalité locale, mais est mis en œuvre de manière minimale. Ce fonctionnement particulier est une adaptation optimale à un contexte fait de rivalités professionnelles au sein d’administrations cloisonnées, d’enjeux politico-financiers liés aux différentes sources de revenus communaux et de tensions politico-institutionnelles liées à une décentralisation tardive. Les impacts du RFU en termes de développement des compétences professionnelles nationales sont insuffisants pour réformer la gestion urbaine depuis l’intérieur de l’administration municipale. Ensuite, alors qu’il vise à centraliser l’information sur les propriétaires présumés de la terre, le RFU se heurte à la marchandisation de cette information et à la territorialisation de la régulation foncière. La mise en œuvre du RFU s’en trouve affectée de deux manières : d’une part, elle s’insère dans ces circuits marchands de l’information foncière, avec cependant peu de succès ; d’autre part, elle a un impact différencié selon les territoires de la régulation foncière. En définitive, l’acte de gérer la ville au Bénin n’est pas devenu automatique avec l’introduction d’instruments comme le RFU. La municipalité se repose plutôt sur les piliers classiques de l’action publique, l’administration et le politique, pour gérer la ville plurielle de manière différenciée. À l’endroit des concepteurs d’action publique, cette thèse plaide pour une prise en compte des modes de régulation existant dans les sociétés africaines, fussent-ils pluriels, reconnaissant les voies originales que prend la construction des institutions en Afrique.
