Fare i conti per decidere se seminare il grano duro
No full textL'articolo affronta il tema delle modalità con cui gli imprenditori agricoli decidono circa la semina del grano duro. Le scelte dei cerealicoltori si basano sulle loro aspettative economiche, talora formalizzate in un conto economico preventivo. Con la riforma della PAC e il disaccoppiamento, il problema del calcolo della convenienza economica è fondamentale per le scelte di semina
Profittabilità e onere tributario delle imprese multinazionali: una analisi empirica sul settore tessile in Italia
No full textFocusing on Textile and Clothing companies in Italy, the aim of this paper is to determine whether there are significant differences in the tax burden of Multinational companies (corporations located in Italy but controlled by foreign corporations and Italian corporations controlling foreign corporations) and domestic companies. This empirical aspect is of great importance from the point of view of a «within-border»
unfair competition among domestic and ME firms located in the same country. ME can make use of different type of tax planning variables with respect to domestic firms, because of tax differential among countries. Some preliminary evidence of profit
shifting behaviour is discussed, suggesting a more systematic and thorough approach
Agent to Agent Talk: “Nobody There?” Supporting Agents Linguistic Communication
No full textWorld-Wide Web technologies and the vision of Semantic Web have pushed for adaptive SW applications to scale up information technologies to the Web, where information is organized following different underlying knowledge and/or presentation models. Interoperability among heterogeneous intelligent agents has become an important research topic in the context of distributed information systems. Communication among heterogeneous agents involves several dimensions. “Ontological commitment” on a shared knowledge model cannot be assumed as a default.
To overcome this problem, we will describe in this article a communication model that bases on the use of natural language. We will argue on main topics involved in using natural language to achieve semantic agreement in agents communication. The model foresees a strong separation among terms and concepts, this difference being often undervalued in the literature, where terms play the ambiguous role of both concept labels and of communication lexicon. For agents communicating through the language, lexical information embodies instead the possibility to “express” the underlying conceptualizations thus agreeing to a shared representation. We will examine in details the different layers involved in agents communication and we will focus on a the different roles played by each element. A novel agent architecture able to tackle with possible linguistic ambiguities by focusing on the conversational level will be deeply described. Three different agent typologies will be presented: Resource agents, embodying the target knowledge, Service agents, providing basic skills to support complex activities and control agents, supplying the structural knowledge of the task, with coordination and control capabilities. NL communication is supported by two dedicated Service agents: a Mediator, that will handle conceptual mismatches arising during communication, and a Translator, dealing with lexical misalignments due to different languages/idioms
Car Stickiness: Heuristics and Biases in Travel Choice
No full textWe conduct a laboratory experiment to investigate the factors determining travel mode choice. Two different scenarios are considered. In the first scenario, subjects have to decide whether to commute by car or by metro. Metro costs are fixed, while car costs are uncertain and determined by the joint effect of casual events and traffic congestion. In the second scenario, subjects have to decide whether to travel by car or by bus, whose costs are determined by a different combination of chance and traffic congestion. Subjects receive feedback information on the actual travel times of both modes. We find that individuals show a marked preference for cars, are inclined to confirm their first choice and exhibit travel mode stickiness. We conclude that travel mode choice is subject to cognitive heuristics and biases leading to robust deviations from rational behaviour
