We study friendship networks under the assumption that people are constrained to build the qualities of their relations. We investigate the connection between (exogenous) assor- tative interests and (endogenous) homophilic patterns, and its welfare implications. Un- der a simple link formation...

This paper empirically investigates the determinants of willingness to pay (WTP) for the environment, employing micro data from the European Value Survey (EVS) over 2008-2010 in 27 European countries. Using ordered logit, logit and partially constrained generalized ordered logit models, we...

The problem of allocating indivisible goods is considered when groups of individuals can make use of their power to plunder other groups. A monarch in a group of individuals is an individual who always obtains one of his most preferred goods. A Paretian condition together with a requirement of...

The paper discusses opportunities to utilize the series of micro-blogs as provided by the Twitter in observation of opinion dynamics. The spontaneity of tweets is more, as the service is attached more to the mobile communications. The extraction of information in the series of tweets is...

The aim of this paper is to demonstrate that dynamic paths in a model of discrete choice with social interactions, which have been developed by Brock and Durlauf (1999, 2001a, 2001b, 2006), converge some self-consistent equilibrium. To this aim, we propose an asynchronous model of...

Land, labor, indigenous knowledge and institutional resources of producers in the Central Highlands of Ethiopia are investigated. Frequency distribution and comparative statistical analysis of the two regions with respect to these and other parameters suggest that in a situation where all...

This paper presents the results from an expert survey on the possibility of a modern barter exchange system (MBES) to be implemented in Bulgaria. MBES is an abstract theoretical construction which helps uncover the reasons why such schemes are successful in a number of countries with different...

We argue in this paper that attention to one's blog is won by paying attention to other bloggers. We derive properties of blogging networks from a model where bloggers trade attention and content. The predictions from the model are then checked against a novel dataset from LiveJournal, a major...

In recent years, due to the growing supply of organic production, the economic performances and the competitive advantages of the farms, have become more dependent on network organisations in the supply chains. This evolution requires methodological approaches able to capture all the variables...

Properties of blogging networks are derived from a model where bloggers devote attention to others, produce content for others, and exchange attention with content within their network of relations. The predictions from the model are tested with a novel dataset from LiveJournal, a major blogging...
