Policy diffusion as empowerment: domestic agency and the institutional dynamics of monetary policy diffusion in China

ABSTRACT

The policy diffusion literature has often focused on external pressures on domestic policy. However, by analysing the evolution of China’s monetary policy regime, we demonstrate a pattern of highly selective diffusion that is largely shaped by domestic political and institutional dynamics. We use an historical institutionalist approach to probe how the most relevant institutionally embedded agents, in this case, those within the Chinese central bank, have strategically engaged with this process. We show how selective diffusion has been shaped by epistemic policy learning through international engagement by China’s central bankers, and, in particular, how they have strategically used imported policy ideas as an institutional empowerment strategy, furthering the interests and agenda of the People’s Bank of China.     

Adding time to social movement diffusion

ABSTRACT

There is now a substantial literature on the diffusion of protest events, tactics, identities, and frames between locations and among movements. This paper asks how the patterns identified in this literature may change as the time scale of diffusion extends across single cycles of protest and beyond the life spans of individual activists. I focus especially on two types of differences: the changing weight of relational and non-relational channels of diffusion; and ways in which, over longer stretches of time, the mediation of diffusion by formal organizations, institutions, and public history works to filter the influence of past activism.     

Social network thresholds in the diffusion of innovations

Threshold models have been postulated as one explanation for the success or failure of collective action and the diffusion of innovations. The present paper creates a social network threshold model of the diffusion of innovations based on the Ryan and Gross (1943) adopter categories: (1) early adopters; (2) early majority; (3) late majority; (4) laggards. This new model uses social networks as a basis for adopter categorization, instead of solely relying on the system-level analysis used previously. The present paper argues that these four adopter categories can be created either with respect to the entire social system, or with respect to an individual's personal network. This dual typology is used to analyze three diffusion datasets to show how external influence and opinion leadership channel the diffusion of innovations. Network thresholds can be used (1) to vary the definition of behavioral contagion, (2) to predict the pattern of diffusion of innovations, and (3) to identify opinion leaders and followers in order to understand the two-step flow hypothesis better.     

Cigarette diffusion and sex differences in smoking

Because the recent narrowing of the sex differential in smoking (and mortality from smoking-related causes) coincides with movement toward gender equality and independence among women, it suggests that rising status among women has contributed to their adoption of male smoking behavior (and ultimately to worsening longevity). However, an alternative "cigarette diffusion" explanation suggests that convergence in male and female smoking is the byproduct of a female lag in the process of cigarette adoption, diffusion, and abatement. Using multilevel models and data for 16 European nations from 1988-1995, the analysis demonstrates consistent support for the predictions of the cigarette diffusion explanation. Smoking of men and women becomes more similar in nations that have the longest history of cigarette use rather than the greatest gender equality.     

Digital access,political networks and the diffusion of democracy

We examine the effects of digital access on the prevalence of democracy and its diffusion via trade, geographical and migration networks across 189 countries between 2000 and 2010. We find that different digital technologies may have varying impacts on freedom while affecting its diffusion via different political networks, and that related changes in civil liberties can be affected by both media freedom and internal political institutions. Our analysis suggests three key mechanisms linking information technology with democratic change and highlights the importance of a country's “susceptibility” to political influence that is triggered by greater digitally induced visibility.     

Modelling free social spaces and the diffusion of social mobilization

Free social spaces have long been emphasized in the social movement literature. Under names such as safe spaces, social havens, and counterpublics, they have been characterized as protective shelters against prevailing hegemonic ideologies and as hubs for the diffusion of ideas and ideologies. However, the vast literature on these spaces has predominantly focused on internal dynamics and processes, thus neglecting how they relate to the diffusion of collective mobilization. Inspired by formal modeling in collective action research, we develop a network model to investigate how the structural properties of free social spaces impact the diffusion of collective mobilization. Our results show that the assumption of clustering is enough for structural effects to emerge, and that clustering furthermore interacts synergistically with political deviance. This indicates that it is not only internal dynamics that play a role in the relevance of free social spaces for collective action. Our approach also illustrates how formal modeling can deepen our understanding of diffusion processes in collective mobilizations through analysis of emergent structural effects.     

Social remittances: migration driven local-level forms of cultural diffusion

"Many studies highlight the macro-level dissemination of global culture and institutions. This article focuses on social remittances--a local-level, migration-driven form of cultural diffusion. Social remittances are the ideas, behaviors, identities, and social capital that flow from receiving- to sending-country communities. The role that these resources play in promoting immigrant entrepreneurship, community and family formation, and political integration is widely acknowledged. This article specifies how these same ideas and practices are remolded in receiving countries, the mechanisms by which they are sent back to sending communities, and the role they play in transforming sending-country social and political life." The data concern migrants from the Dominican Republic to the Boston area of the United States.     

Some implications of the emergence and diffusion of medical expert systems

This paper has two sections. The first introduces the area of medical decision making and the use of artificial intelligence techniques for developing medical expert systems. It also briefly discusses how a physician and an expert system interact, using the INTERNIST-I system as an example. An elaboration of several technical problems which expert systems must overcome for them to be accepted and used by physicians ends this discussion. The second section considers the implications medical expert systems for physicians and patient care. It suggests that medical expert systems regulate and routinize physicians' work. Moreover, the encoding of expert knowledge in a computer program will likely demystify the practice of medicine, nullifying much of the art of medicine. Alternatively, medical expert systems may improve the physician's decision making, extend the practitioner's capabilities, and hence increase the physician's prestige. Moreover, computer aided decision making could speed diagnosis, especially for difficult cases, thus providing the doctor with time for other pursuits. However, medical expert systems will be a mixed blessing for patient care. On the one hand, they could provide expert advice in medically underserved areas, decrease the number of referrals patients and physicians must contend with, while offering expert advice to a greater number of patients. On the other hand, expert systems could further alienate patients from practitioners and from the health system in general. Even more than other medical technologies, computers in the doctor's office could increase the separation between the doctor and patient, while lowering the physician's confidence in her or his own decision making. The conclusion discusses the importance of control over work in determining the use of technology and the influence of the changing medical power structure on the use of expert systems.I thank J. Zvi Namenwirth for his careful review and thoughtful comments on this and previous drafts of this paper. I also appreciate the useful suggestions offered by anonymous reviewers of an earlier draft.     

The diffusion of public private partnerships: a world systems analysis

ABSTRACT

This paper analyzes the diffusion of neoliberal policies from the UK to Australia and New Zealand, and then to the Asia-Pacific region. The analytical framework employed is the world systems model developed by Immanuel Wallerstein. The primary focus of attention is the spread of public-private partnerships (PPPs) modelled on the UK Private Finance Initiative (PFI). Despite the demise of the PFI in its country of origin, and repeated failures in Australia and New Zealand, there is still considerable enthusiasm for the model in Australasia reflected in eagerness to export national expertise through aid and financial links.     

The international diffusion of an innovation: The spread of decimal currency

This paper argues that decimalization of currency diffused as a consequence of all three forms of isomorphism: normative, coercive, and mimetic. Furthermore, it is ambiguous as to whether the normative isomorphism was well founded. The patterns of denominations show variety by country as a consequence of a number of factors, including cultural ones. These patterns tend to follow a powers-of-two (binary) principle for smaller denominations and a purer decimal principle for larger denominations, reflecting their utility for cash transactions and for store-of-value functions, respectively.     

Affinity Paths and information diffusion in social networks

Widespread interest in the diffusion of information through social networks has produced a large number of Social Dynamics models. A majority of them use theoretical hypothesis to explain their diffusion mechanisms while the few empirically based ones average out their measures over many messages of different contents. Our empirical research tracking the step-by-step email propagation of an invariable viral marketing message delves into the content impact and has discovered new and striking features. The topology and dynamics of the propagation cascades display patterns not inherited from the email networks carrying the message. Their disconnected, low transitivity, tree-like cascades present positive correlation between their nodes probability to forward the message and the average number of neighbors they target and show increased participants’ involvement as the propagation paths length grows. Such patterns not described before, nor replicated by any of the existing models of information diffusion, can be explained if participants make their pass-along decisions based uniquely on local knowledge of their network neighbors affinity with the message content. We prove the plausibility of such mechanism through a stylized, agent-based model that replicates the Affinity Paths observed in real information diffusion cascades.     

A model of HIV diffusion from a single source: A scholium

In Nahmias (1989), a mathematical model was developed for the spread of AIDS by a female prostitute, which assumed that the numbers of visits of a given client to that prostitute had the geometric distribution. However, the geometric distribution gives incorrect results in some cases. In this note, we consider a normal distribution for the number of visits and show how the expected numbers of clients to which she transmits the virus changes as a result.     

Application of diffusion maps to identify human factors of self-reported anomalies in aviation

A study investigating what factors are present leading to pilots submitting voluntary anomaly reports regarding their flight performance was conducted. Diffusion Maps (DM) were selected as the method of choice for performing dimensionality reduction on text records for this study. Diffusion Maps have seen successful use in other domains such as image classification and pattern recognition. High-dimensionality data in the form of narrative text reports from the NASA Aviation Safety Reporting System (ASRS) were clustered and categorized by way of dimensionality reduction. Supervised analyses were performed to create a baseline document clustering system. Dimensionality reduction techniques identified concepts or keywords within records, and allowed the creation of a framework for an unsupervised document classification system. Results from the unsupervised clustering algorithm performed similarly to the supervised methods outlined in the study. The dimensionality reduction was performed on 100 of the most commonly occurring words within 126,000 text records describing commercial aviation incidents. This study demonstrates that unsupervised machine clustering and organization of incident reports is possible based on unbiased inputs. Findings from this study reinforced traditional views on what factors contribute to civil aviation anomalies, however, new associations between previously unrelated factors and conditions were also found.     

Modeling the dynamism of HIV information diffusion in multiplex networks of homeless youth

Cascade and threshold models are widely used to predict information diffusion in social networks, yet their characterization of networks as static and monoplex limit their ability to accurately predict how information propagates in dynamic, multiplex social environments. Using data from a peer-led HIV prevention intervention for homeless youth, we determine whether manipulating the baseline social network by (1) adding ties observed at later time points, and (2) accounting for alternative relational contexts improves each model’s predictive accuracy. Results show that the addition of new ties improves the performance of both models, while substituting the context of interaction yields only minor improvements.     

Foreign aid and the rule of law: Institutional diffusion versus legal reach

This paper examines the role of bilateral foreign aid in supporting the diffusion and enactment of common models and institutions of the rule of law among aid-recipient low- and middle-income countries. We ask whether aid targeted at security-sector reform and the rule of law influences the adoption of constitutional and legal reforms over time (institutional diffusion), and whether aid also supports more effective implementation of the rule of law, writ large (legal reach). We use event history and fixed-effects panel regression models to examine a sample of 154 countries between 1995 and 2013 to answer these questions. Our findings suggest that aid does increase the likelihood of adopting several rule of law reforms, but its effect on increasing the depth or quality of rule of law over time within countries is much less substantial. These findings suggest that though aid may play a role in supporting the diffusion of models contributing to state isomorphism among countries, it is less effective at increasing the pervasiveness and quality of such model’s implementation. This discrepancy between the effectiveness of bilateral aid in promoting law on the books versus law in action in aid recipient countries calls into question the current approach to rule of law reforms.     

Human rights and world culture: The diffusion of legislation against the organ trade

ABSTRACT

Due to the process of globalization, rapid medical and technological advances, and the persistence of the global scarcity in organs, the organ trade has grown to become an international issue of increasingconcern. Over the past several decades, more than 100 countries have passed legislation banning the commercial trade in organs. What explains this rapid, global diffusion of commercial transplantation laws, and what are the key factors influencing legislation? This studyexplores these questions through an analysis based on sociology’s world culture, world polity theory. Utilizing survival analysisn models, the study covers 127 countries from 1965-2012. Results offer support for the world culture/world polity theoretical framework, while economic development also impacts legislation. The global trendtoward legislation is influenced by global, cultural, and economic factors.     

The origins and early diffusion of “shareholder value” in the United States

The shareholder value conception of the firm and its consequences for the functioning of corporations have been studied from a variety of disciplinary and theoretical perspectives. In this article we examine in more detail than has been done sofar the origins and early adoption of this particular conception. By investigating public business sources from the perspective of field theory, we argue that the rise and early diffusion of “shareholder value” are best understood as a function of the changing power relations in the economic field during the first half of the 1980s. The deep economic recession at the end of the 1970s and early 1980s led to a crisis in the prevailing management beliefs, offering newcomers the opportunity to promote alternative business strategies, among which the shareholder value conception became dominant. The sources studied indicate that the spokespersons of the new business conception were initially wealthy outsiders, corporate “raiders,” who used the economic crisis to oppose management and acquire shares in undervalued firms with the threat of restructuring and selling parts of them in the name of shareholders’ interests. Although these hostile take-overs, or threats of take-overs, were widely contested, the Reagan administration blocked regulation and stimulated the take-over market. The rivalry between “raiders” and public pension funds over the profits of these takeovers led to the founding the Council of Institutional Investors (1985), which adopted the shareholder value doctrine inaugurating the organized activism of public pension funds with regard to the management of firms. It was thus in all likelihood the competition and conflict among different groups of shareholders, primarily corporate raiders and pension funds, that triggered the shift in the balance of power between managers and shareholders. Since managers found profitable ways to adapt to the new balance of power, the shareholder value ideology spread rapidly through the economic field, becoming the dominant business model of North American firms in the second half of the 1980s.
