On the basis of the recent concepts of epistemic communities and communities of practice, we show that the firm can be defined according to a form of double duality: cognitive and organisational. The interest of this approach is to put ahead the differentiated behavior from the manager and the...

It has recently been shown that the incorporation of weight restrictions in models of data envelopment analysis (DEA) may induce free or unlimited production of output vectors in the underlying production technology, which is expressly disallowed by standard production assumptions. This effect...

The dynamics of wine purchasing behavior is studied focusing on the respective impacts of the word-to-mouth versus wine expert judgements and reputations. To investigate the problem we apply the Galam model of opinion dynamics to agents who have to select a preference about which type of wine to...

Since 2006 the conversion of vineyards to organic or biodynamic vineyards has been accelerating in France, and the annual rate of conversion varies between 20- 25% per year, attaining the total surface of 61.055 ha of bio vineyards in 2011. This growth is even more striking in the light of the...

The extensions to the variable (VRS) and the constant (CRS) returns-to-scale models developed by Banker and Morey are considered among the main approaches to the incorporation of exogenously fixed factors in models of data envelopment analysis (DEA). Recently, Syrjänen showed that the Banker...
