Trust and growth: a shaky relationship 总被引:2,自引:0,他引:2
We conduct an extensive robustness analysis of the relationship between trust and growth by investigating a later time period
and a bigger sample than in previous studies. In addition to robustness tests that focus on model uncertainty, we systematize
the investigation of outlier influence on the results by using the robust estimation technique Least Trimmed Squares. We find
that when outliers (especially China) are removed, the trust-growth relationship is no longer robust. On average, the trust
coefficient is half as large as in previous findings.

Recent theoretical research on oligopolistic competition suggests that under certain conditions prices increase with the number of competing firms. However, this counterintuitive result is based on comparative-static analyses which neglect
the importance of dynamic strategies in naturally-occurring markets. When firms compete repeatedly, supra-competitive prices
can become sustainable but this is arguably more difficult when more firms operate in the market. This paper reports the results
of laboratory experiments investigating pricing behavior in a setting in which (static) theory predicts the counterintuitive
number effect. Under a random matching protocol, which retains much of the one-shot nature of the model, the data corroborates
the game-theoretic prediction. Under fixed matching duopolists post substantially higher prices, whereas prices in quadropolies
remain very similar. As a result, the predicted effect is no longer observed, and towards the end the reverse effect is observed.

Documentation and analysis of prevention goals and interventions employed by community-based injury prevention programmes is vital to advance the knowledge and understanding of synergistic multi-strategy injury prevention programmes. This study examined the goals and interventions of 25 Scandinavian community-based injury prevention programmes in WHO-designated Safe Communities. Collection and analysis of quantitative data from survey questionnaires to the programme coordinators was followed by collection and analysis of qualitative data from structured interviews with programme coordinators from eight of the programmes. The results demonstrated that the programmes under study predominantly relied on "intuitive" and subjective methods for selecting interventions. The programmes largely failed to transform injury surveillance data into information and knowledge that could prioritize community safety strategies and measures, due to insufficient time and personnel resources. The results demonstrated the importance of combining passive approaches with active interventions. Educational efforts were considered essential to the programmes. The programmes preferred to rely on broadly stated goals rather than specific objectives. 相似文献

Despite the last few decades’ devotion to deliberative methods in risk communication, many studies point to how important challenges arise when citizens are engaged in public dialogue. Since the era of enlightenment public dialogue has occupied a position as a normative ideal for political governance. But ideals are social constructions that have a tendency to direct attention away from underlying conflicts. The concept of dialogue is no exception, and exemplified by the Danish solution to dealing with public scepticism in relation to technological controversies, the internationally acclaimed ‘consensus conference’, the paper seeks to offer a better understanding of the contemporary use of the concept of dialogue as well as its ancient roots. The paper argues that behind the aspirations for deliberation lie two opposing models of dialogue. When these two models encounter in deliberative processes, their different presumptions about the role of communication symmetry are likely to appear. This points to how the models hold very different expectations as to the dialogical outcome, thus imposing some fundamental conflicts regarding the political efficacy of citizen engagement as a strategy for bridging the gap between expert and lay attitudes to societal risks. 相似文献

This article investigates the quality of register data in the context of a standardized quality framework. The special focus of this work lies on the assessment of census data and how to deal with uncertainty that arises from multiple sources (registers). To take the uncertainty associated with support and conflict between several registers into account, Dempster–Shafer's theory of evidence is applied. This ‘fuzzy’ approach allows us to investigate the quality of databases with multiple underlying sources for a single attribute and to provide both quality measures and plausibility intervals. 相似文献

Most developed countries have compulsory insurance programs for temporary disability, that is, cash benefits for non‐work‐related sickness. Despite the economic significance of these programs, little is known about their effects on work absenteeism or labor supply. We exploit a policy reform that consisted of the abolishment of a waiting day together with an increase of cash benefits for short sick leaves. We find that the total number of days of sickness absence was reduced by the reform, which is likely due to the fact that the abolishment of the waiting period made it less costly for workers to be absent for short periods. 相似文献

In this article we portray and unpack the fabric of urban expansion in contemporary Luanda. In doing so, we examine interdependencies and complementarities between the organization of oil extraction off the coast of Angola, the emergence of particular modalities of modernist city planning for the expansion of its capital city, and the proliferation of cement blocks in the making of new urban forms throughout its burgeoning peripheries. By showing how urban development has unfolded through the interconnected realization of multiple kinds of systematizing blocks—namely oil blocks, city blocks and cement blocks—we analyse key material components in the production of new markets and urban spaces in the Angolan capital. By tracing forms of capitalism and modularity in the making of contemporary Luanda, we develop the concept of blocos urbanism to draw attention to modes of standardization and the production of legibility in contemporary processes of urbanization. Through this study, we aim to contribute to the conceptual apparatus for deciphering our global urban condition. 相似文献

Do asylum-seekers respond to policy changes in their destination country, and to what extent? We approach this question by using high-frequency data, and we focus on a sudden liberalization in Swedish policy toward Syrian asylum-seekers, which implied permanent instead of temporary residence. We show a clear and fast, yet temporary, increase in Syrian asylum applications in Sweden after the policy change. Also, the policy caused a shift – not limited to the short term – in the share of individuals arriving without family, and consequently in the share applying for family reunification. Our study adds quasi-experimental evidence to the literature on inter-country asylum flows and migration policy. 相似文献
