abstract Existing theories on the influence of social networks on creativity focus on idea generation. Conversely, the new product development literature concentrates more on the selection of ideas and projects. In this paper we bridge this gap by developing a dynamic framework for the role of social networks from idea generation to selection. We apply findings from creativity and behavioural decision‐making literature and present an in‐depth understanding of the sociological processes in the front‐end of the new product development process. Our framework builds on the importance of mutual understanding, sensemaking and consensus formation. The propositions focus on both network structure and content and highlight the need to have strong ties and prior related knowledge, to incorporate decision makers, and to move over time from a large, non‐redundant and heterogeneous to a smaller and more cohesive network structure. We conclude with a discussion on empirical validation of the framework and possible extensions.  相似文献

The emergence of formal Foresight programmes in science policy across Europe is examined in terms of government's response to the changes in, and especially the uncertainties of, contemporary innovation. The paper explores this through deploying Beck's notion of the “risk society”, asking how far Foresight can be construed as the management of new technologies by the transition towards the “negotiation state”. It shows how, through a discussion of the social management of new health technologies, a tension arises between the priorities and regimes of the new “negotiation” and those of the former “provident” (or welfare) state. The emergence of new technologies will be shaped by the institutional assumptions and processes operating within the different policy regimes.  相似文献

This paper explores how threshold uncertainty affects cooperative behaviors in the provision of public goods and the prevention of public bads. The following facts motivate our study. First, environmental (resource) problems are either framed as public bads prevention or public goods provision. Second, the occurrence of these problems is characterized by thresholds that are interchangeably represented as “nonconvexity,” “bifurcation,” “bi-stability,” or “catastrophes.” Third, the threshold location is mostly unknown. We employ a provision point mechanism with threshold uncertainty and analyze the responses of cooperative behaviors to uncertainty and to the framing for each type of social preferences categorized by a value orientation test. We find that aggregate framing effects are negligible, although the response to the frame is the opposite depending on the type of social preferences. “Cooperative” subjects become more cooperative in negative frames than in positive frames, whereas “individualistic” subjects are less cooperative in negative frames than in positive ones. This finding implies that the insignificance of aggregate framing effects arises from behavioral asymmetry. We also find that the percentage of cooperative choices non-monotonically varies with the degree of threshold uncertainty, irrespective of framing and value orientation. Specifically, the degree of cooperation is highest at intermediate levels of threshold uncertainty and decreases as the uncertainty becomes sufficiently large.  相似文献

ABSTRACT . “Bargaining with the Devil: Commentary on the Ostroms’‘Quest for Meaning in Public Choice’” provides a commentary on Elinor Ostrom and Vincent Ostrom's paper, “The Quest for Meaning in Public Choice.” This discussion focuses on the challenging tension that exists between social scientific knowledge and social practices. It suggests that historical agents may have solved the dilemma of cooperation prior to rational choice theorists’ invention of the public goods problem.  相似文献

In this article, we address a gap in the meaningful work literature by exploring the processes by which work is experienced as meaningless. We adopt the lens of relational sociology and, through interviews with 45 participants in four very different occupations, we found that meaninglessness arises through four relational processes: powerlessness, disconnection, devaluation and self-doubt. Individuals enacted six agential responses to this experience. Two of these, resisting and responsibility-taking, were “reinstatement” strategies and four, acceptance, distancing, minimising and resistance, were “coping” strategies. In addition, some informants used “switching” as a framing device. These responses were not equally available to all workers in all occupations, suggestive of a stratified experience of work meaninglessness. Our study contributes to understandings of how work is rendered meaningless and how individuals might respond.  相似文献

In recent decades economists started discovering the importance of the social dimension of economic interactions. Contemporary economics has borrowed several sociological concepts for its own use, among the most important being the concept of social capital. However, this transfer within disciplines did not occur without a loss—the nature of social capital in economics remains confused and obscure. The purpose of this article is to clarify it, specify the possibilities for its use, and discuss their limits. It is argued that economics once also possessed a view of human beings that was more “socialized” than the modern neoclassical Homo oeconomicus, and that this more “socialized” view still exists in the Austrian school of economics. Because this tradition of economic thought has also developed an elaborate capital theory, it can serve as an ideal source where we can look for inspiration in the current social capital debate. First, social capital is (re)defined along these lines as an individual's asset connected with recognized reciprocity (as opposed to interactions usually classified as “altruistic”). Then major critical claims about the relation between social and physical capital are answered and the connection between social capital, trust, and social norms is described.  相似文献

In response to public pressure to reduce air pollution, governments are forced to consider alternate means to limit auto emissions. This paper addresses the problem of evaluating these regulatory policies and choosing the one that is best for society.Economic tradeoffs play an important role in the analysis of emission control policies. Cleaner air comes only at a price, and the judgments as to “How clean?” At what price?” and “At who's expense?” are crucial. Once these value issues are resolved, questions of implementation remain. “How do regulatory policies such as mandatory emission standards for cars compare with a system of emission taxes?” “Are there ways to collect a fee from drivers to compensate those who breathe their pollution, without taxing emissions directly?”Our approach is first to describe a decision-focused analytical procedure for evaluating various policy alternatives. This procedure is then demonstrated with a preliminary analysis of representative emission control plans for the Los Angeles air basin. Both emission standards and market or “pricing” alternatives are considered. These plans include: present (1975) emission standards; an emission tax; an increase in the gasoline tax; a policy of no government control.The preliminary analysis shows market mechanisms to be superior to present emission standards. Many significant advantages of market mechanisms are discussed, though this conclusion is due primarily to—in our opinion—inappropriate value judgments that are implicit in the present standards.The analytical framework is very general, and it can be applied to a wide variety of social decisions involving externalities. The quantitative models developed, though preliminary, can be used by organizations such as regional planning agencies or pollution control boards. However, these models must not be viewed as formulas for answers to social problems. Rather, they are intended as aids for the policy maker that will help him or her balance the many factors that influence the decision and provide insight to the wisest social course of action.  相似文献

We propose a new mathematical model for efficiency analysis, which combines DEA methodology with an old idea—Ratio Analysis. Our model, called DEA-R, treats all possible ratios “output/input” as outputs within the standard DEA model. Although DEA and DEA-R generate different summary measures for efficiency, the two measures are comparable. Our mathematical and empirical comparisons establish the validity of DEA-R model in its own right. The key advantage of DEA-R over DEA is that it allows effective integration of the model with experts’ opinions via flexible restrictive conditions on individual “output/input” pairs.  相似文献

Elinor Ostrom's work on the commons has convinced mainstream economists that “collective” governance of the commons can overcome the “tragedy of the commons” and “free‐rider problems.” Yet, a more systematic appraisal of Ostrom's work shows that it contains no concept of justice. Her idea of rights is extremely limited, often tied to the notion of joint, rather than equal, rights. Indeed, for Ostrom, the notion of the commons is socially separatist and not ecological. Ostrom uses historical examples, but without analyzing how common possession historically evolved and was undermined by external forces. Hence her proposed “collective action” to save the commons actually accelerates the real threats to the commons. A strikingly different and more holistic approach to the commons is offered by Henry George, who posits the commons as the most important path to social, economic, and ecological sustainability. Unlike Ostrom, who studied the commons “scientifically” to show that some goods are neither private, public, nor club‐based, George studied the commons to understand and remove injustice at the roots. His approach is more critical and certainly more relevant today in showing that another world is possible. However, George's work too, requires significant changes to update its framing of the meanings, prospects, and future of the commons.  相似文献

This research attempts to provide responses to the question “Does unemployment make people less likely to give?” by developing a theoretical model based on consumer choice and labor supply and using data from the World Giving Index, collected for 153 countries from 2010 to 2015. The results from panel data and from ordered probit estimations revealed that countries with higher unemployment rates (especially male and female youth unemployment) are associated with values related to a less generous profile on the part of respondents. Our results were obtained while controlling for a convenient set of variables, and the estimated coefficients generated an extension of this discussion toward the models of welfare states and the giving practices worldwide.  相似文献

We structure this response to the commentaries to our article “Transparent modeling of influenza incidence: Big data or a single data point from psychological theory?” around the concept of psychological AI, Herbert Simon’s classic idea of using insights from how people make decisions to make computers smart. The recency heuristic in Katsikopoulos, ?im?ek, Buckmann, and Gigerenzer (2021) is one example of psychological AI. Here we develop another: the trend-recency heuristic. While the recency heuristic predicts that the next observation will equal the most recent observation, the trend-recency heuristic predicts that the next trend will equal the most recent trend. We compare the performance of these two recency heuristics with forecasting models that use trend damping for predicting flu incidence. Psychological AI prioritizes ecological rationality and transparency, and we provide a roadmap of how to study such issues. We also discuss how this transparency differs from explainable AI and how ecological rationality focuses on the comparative empirical study and theoretical analysis of different types of models.  相似文献

We present an idealized model of a one-dimensional “city”, characterized by interactions between the costs of social prejudice, transportation, and housing.Using variational techniques, we show that under rather simple assumptions the model leads to a “suburban-urban” dichotomy, and also to a “segregated” neighborhood structure.In this abstract city, optimal “social policies” result in Pareto-efficient population distributions.  相似文献

Since the 1980s, much debate has revolved around Karl Polanyi's concept of the “dis/embedded economy,” generating some light and not a little heat. This paper looks at three reasons that account for part of the “heat.” It begins by tracing the sources upon which Polanyi drew. They include Karl Marx, Ferdinand Tönnies, and Max Weber, along with anthropology of the inter‐war period, and German and American Institutionalist economics. After exploring the differing ways in which these varying currents conceptualize the relationship between economy and society, I explore the different interpretations of what Polanyi means by embeddedness, and the different purposes to which contemporary economic sociologists have put the term. For some, he is held up as the originator of a line of sociological analysis that treats “the economy” as a subsystem “embedded in” a social system. In this reading the emphasis is upon the moral underpinnings of market behavior, in contrast to the naturalism of Ricardo, Malthus and their heirs. For others, his “disembedding” thesis contains a more radical tale: of the market economy coming to dominate “society,” bringing forth a sorcerer's apprentice world of untrammeled market forces that, although human creations, lie beyond conscious human control.  相似文献

Defense activities exercised in a specific region may alter the region's economic performance. An accurate assessment of the potential economic impacts of defense activities is a valuable undertaking to enable regional planners to prepare for changes. The variety in the methods (among others, input–output models, economic base models, Keynesian regional multipliers, fixed‐effects estimators, and case‐study approaches) inspired by geography, sociology, and political science can pose a dilemma. We detail the historical and theoretical background of each method, as well as select exemplary cases where these methods were applied. By examining old and “new” methods, we aim to construct a typology that could be valuable to all stakeholders. In this sense, defense economics can also contribute to the allied social sciences by outlining evaluation methods that may be applicable to other fields.  相似文献

In this paper the author identifies two related problems in financial modelling. First, the problem of implementing financial decision theory in practical decision situations and, second, the need to develop existing managerial financial models. A discussion of organization decision processes indicates possible reasons for the relative failure of management science and financial theory based models in practice and the predominance of accounting based models. This analysis of strategic decision processes suggests key design features for the implementation of financial models. Finally, research orientated models designed using these guidelines are seen as appropriate media for the transfer of knowledge between financial decision theory and financial practice. This is seen as providing a tentative basis for the development of managerial financial models. Throughout the paper the author uses examples from his own experience in model building in instalment credit, and leasing financial intermediaries, i.e. “Finance Houses”.  相似文献
