Opinion leaders are the people in a social network who have the greatest influence on other people's acknowledgment or adoption of products/services in the diffusion process of technological innovation. In this research, we investigate which opinion leader is the best marketing choice in terms of diffusion speed and maximum cumulative number of adopters, using a social network approach and threshold model. On the basis of the simulation result, we find that opinion leaders with high sociality are the best ones for fast diffusion, whereas those with high distance centrality are the best ones for the maximum cumulative number of adopters. Moreover, we conclude that the characteristics of effective opinion leaders selected as initial adopters could vary depending on the characteristics of the social network and type of innovation. Finally, we find that opinion leaders affect the diffusion process only when the percentage of initial adopters reaches a critical mass.  相似文献

滑雪场的空间分布及空间重心的变化可以反映出一定时期内区域冰雪体育旅游的发展趋势。以冬奥会赛区--北京—张家口地区(以下简称"京张地区")滑雪场为研究对象,通过重心分析方法,揭示了近20年京张两地滑雪场空间格局的变化特征,并据此划分了冰雪产业的发展阶段。结果表明:(1)1996—2018年北京市滑雪场建设大致经历了"快速扩张""中速发展"和"稳定发展"3个时期,而张家口则基本上呈现"缓慢萌芽"和"快速扩张"2个阶段;北京市滑雪场呈分散状分布,而张家口滑雪场则呈现集中分布。(2)近20年京张地区滑雪场空间重心总体表现为先向东南方向移动(由张家口到北京)而后又向西北折返(由北京向张家口)的趋势,2010年前后是转折点,而申奥等政策因素是促进重心移动路径发生逆转的主要原因。(3)京张地区滑雪场重心和规模重心移动较好反映了数量与规模的扩张速度,为理解京张地区以滑雪场为核心的冰雪体育运动发展提供了新的研究视角,为京张体育文化旅游产业带的健康发展提供了决策依据。  相似文献

I consider repeated games with private monitoring played on a network. Each player has a set of neighbors with whom he interacts: a player's payoff depends on his own and his neighbors' actions only. Monitoring is private and imperfect: each player observes his stage payoff but not the actions of his neighbors. Players can communicate costlessly at each stage: communication can be public, private or a mixture of both. Payoffs are assumed to be sensitive to unilateral deviations. First, for any network, a folk theorem holds if some Joint Pairwise Identifiability condition regarding payoff functions is satisfied. Second, a necessary and sufficient condition on the network topology for a folk theorem to hold for all payoff functions is that no two players have the same set of neighbors not counting each other.  相似文献

A survey carried out to study problems related to Indian vasectomy camps organized at Patna and Jamue towns had the following major purposes: 1) to determine to what extent vasectomy adopters were aware of the family planning program; 2) to determine advantages perceived of adopting vasectomy; 3) to determine how the adopters became aware of the vasectomy camps; and 4) to determine why adopters chose permanent conception control. 200 adopters from Patna and an equal number from Jamue were selected, based on an accidental sampling technique whereby each adopter was contacted and persuaded to be interviewed. It was found that a majority of the adopters were illiterates. Among advantages listed by adopters, the importance of family planning seemed to be subdued by propensity to better their economic condition. It was seen that the literate adopters have a much higher proportion of awareness of the need for family planning and population control. Concerning diffusion of information, the informal and interpersonal sources were equally effective and conducive for the adopters. More than l/2 of the adopters relied upon information provided by friends. In general, higher levels of education correlate with less influence of friends as communicators. The official sources turned out to be effective for the more highly educated adopters. The following advantages were called out as reasons for vasectomy adoption by adopter : 1) permanence; 2) economical reasons; 3) no reason; or 4) many reasons. Whatever the reasons, it is obvious that vasectomy is gaining momentum gradually and people are becoming aware of the underlying advantages of permanent conception control.  相似文献

This work aims at providing a framework for the analysis of governance in networks of cooperative firms. It builds on four bodies of literature: cooperation, transaction costs, monopoly capitalism, production networks. The framework associates the specific principles that define the identity of cooperative organizations (self‐help, member ownership, democratic control, financial participation, limited capital remuneration) alongside more general governance levels (embodied values, property rights, control, resource allocation). We then apply the same dimensions to production networks and propose a stylized networking model for cooperatives. We introduce market power, and identify two polarized types of networks: (1) heterarchical forms of coordination based on cooperation and mutual help, (2) hierarchical coordination based on exclusive direction. We compare both types with our normative framework providing examples and brief case studies for each network type. Recommendations to scholars and practitioners point at the opportunity to discriminate inter‐firm relations and production development strategy in terms of the values of cooperation, at all governance levels.  相似文献

We analyze a simultaneous ascending auction with anonymous item prices, for two items that are substitutes. This popular format entails increased opportunities for coordination among bidders, since bids are observable and can be used as signaling. This has happened, e.g., in the Netherlands 3G Telecom Auction and in the FCC auctions.While it may seem that such bidding harms economic efficiency, we show that side communication may actually improve efficiency: We describe an ex-post subgame-perfect equilibrium, with limited communication, that is ex-post efficient. In contrast, without communication, we show that there is no ex-post equilibrium which is ex-post efficient in this auction.In this equilibrium, bidders initially report true demands, and then perform a single demand reduction at a certain point, determined using a single message exchanged between the bidders. This limited signaling opportunity resolves the strategic problems of myopic bidding, and may improve the social welfare.  相似文献

Our purpose here is to engage in a cross-disciplinary discussion between Austrian economics and social network theory. In particular, we ask what role social networks play in the extended order in regard to both individual discovery and whether social networks can be the source of widespread unintended cooperation among individuals unknown to one another. Although Austrians have examined the function that market prices play in generating social cooperation, such discussions tend to steer clear of non-priced environments, such as interaction within social networks. We seek to explore this gap. While we acknowledge that non-price information feedback mechanisms such as status and reputation lack the calculability so crucial to market coordination, we argue that they can nonetheless mimic other important qualities of market prices and generate widespread unintended social cooperation among people unknown to one another. After a general discussion, we apply these ideas to online philanthropic communities.  相似文献

We explore the manner in which the structure of a social network constrains the level of inequality that can be sustained among its members, based on the following considerations: (i) any distribution of value must be stable with respect to coalitional deviations, and (ii) the network structure itself determines the coalitions that may form. We show that if players can jointly deviate only if they form a clique in the network, then the degree of inequality that can be sustained depends on the cardinality of the maximum independent set. For bipartite networks, the size of the maximum independent set fully characterizes the degree of inequality that can be sustained. This result extends partially to general networks and to the case in which a group of players can deviate jointly if they are all sufficiently close to each other in the network.  相似文献

This paper reports the results of an experimental investigation of dynamic games in networks. In each period, the subjects simultaneously choose whether or not to make an irreversible contribution to the provision of an indivisible public good. Subjects observe the past actions of other subjects if and only if they are connected by the network. Networks may be incomplete so subjects are asymmetrically informed about the actions of other subjects in the same network, which is typically an obstacle to the attainment of an efficient outcome. For all networks, the game has a large set of (possibly inefficient) equilibrium outcomes. Nonetheless, the network architecture makes certain strategies salient and this in turn facilitates coordination on efficient outcomes. In particular, asymmetries in the network architecture encourage two salient behaviors, strategic delay and strategic commitment. By contrast, we find that symmetries in the network architecture can lead to mis-coordination and inefficient outcomes.  相似文献

It is well known that a stage game with infinite choice-sets, unless it contains a public coordination-device in each stage, may have no subgame perfect equilibria. We show that if a game with public coordination-devices has a subgame perfect equilibrium in which two players in each stage use non-atomic strategies, then the game without coordination devices also has a subgame perfect equilibrium.

The aim of the article is to relate the formation of influence networks to the coexistence of technologies in the long run. In the spirit of Plouraboue et al. (1998), we postulate that potential adopters of a technology are situated in a social network. In our model, initial relations are partly negative and all the expected utilities are revised in parallel. In the case of an exogenous network, opinions can fluctuate endlessly. When agents reallocate their relationships, this reinforces trust in agents whose opinion is close to theirs. As a result of this process, the network stabilizes in the long run, generating diversity in expected utilities.  相似文献
