“…Our measure of risk attitudes, as introduced by Holt and Laury [27], results in nine categories of risk aversion. 17 We thus categorize subjects ranging from nine or 10 risky choices (highly risk loving) to zero or one risky choices (very highly risk averse). The results presented in Table 3 show that most of the subjects were risk averse.…”

“…Next to pure network formation models, increasing attention has been paid in recent years to models of network disruption (see, e.g., Hoyer and De Jaegher [11], Hoyer and De Jaegher [12] Dziubiński and Goyal [13], Dziubiński and Goyal [14], Goyal and Vigier [15], Haller [16] or Haller and Hoyer [17]). These theoretical models build on the benchmark models of network formation, adding an understanding of how the incentives of players in the network formation model might be altered, if they know that the network will be attacked by outside forces after it has been built.…”

“…In centralized models, such as Dziubiński and Goyal [13], Dziubiński and Goyal [14], Goyal and Vigier [15], Hoyer and De Jaegher [12] or Haller [16], a network designer forms the network, anticipating a subsequent attack. In decentralized models, such as Hoyer and De Jaegher [11] or Haller and Hoyer [17], the nodes are individual players that build the network.…”

Theoretical models on network formation focus mostly on the stability and efficiency of equilibria, but they cannot deliver an understanding of why specific equilibrium networks are selected or whether they are all actually reachable from any starting network. To study factors affecting equilibrium selection, we designed a network formation experiment with multiple equilibria, which can be categorized in terms of the demand on players’ farsightedness and robustness to errors. In a second scenario, we increase the need for farsighted behavior by players, as well as the perceived riskiness of equilibria by adding a stage in which the network is disrupted. This setting allows us to analyze the interplay between the need for farsightedness and perceived risk of errors and its effect on network formation and equilibrium selection.

Purpose This paper aims to focus on two basic dimensions of group work: cooperation and transfer of information. This paper has two objectives. The first objective is to analyse the effect of cooperation and transfer of information in group work according to employees’ perceptions of the Rioja wine industry. The second objective is to analyse the existence of significant differences in the perception of the basic dimensions of group work under different organisational contexts in the Rioja wine industry. Design/methodology/approach The participants in the study are 230 workers from the Rioja wine industry. The data is collected through a personal interview using a questionnaire. Hypotheses are tested by multiple regression analysis. Findings The results indicate firstly that cooperation and transfer of information is related to “group work” variable positively, and secondly, significant differences were found in each of the contexts analysed. Besides, it has been found that the variable “transfer of information” is more explanatory of group work differences in organisational contexts than the variable “cooperation”. Originality/value This study verified that there is no homogeneity in group work in the Rioja wine industry. This study contributes to the knowledge about a significant industry of the economy and culture of the Rioja region, and the wine sector in general.

“…They analyze both cases of node deletion and link deletion. Exceptionally, Haller and Hoyer [6] is a decentralized network formation model just like Jun and Kim [1], but it assumes no information decay, either. It uses the solution concept of Nash stability, whereas Jun and Kim [1] proposes a new solution concept of C q -stability which shares the spirit of pairwise stability but is stronger than that.…”
