How do economic policy uncertainty and geopolitical risk drive Bitcoin volatility?

We investigate how economic policy uncertainty (EPU) and geopolitical risks (GPR) impact Bitcoin volatility with respect to factors related to type and nationality of uncertainty, investigated period, relationship horizon and extreme conditions. Applying ARDL model and quantile regression for monthly data from August 2010 to September 2021, we reveal that June 2014 corresponds to a key date that marks a reversal in the investigated relationship. Furthermore, we show that the relationship between uncertainty and bitcoin volatility changes according to different factors. US uncertainty has short run effects on Bitcoin volatility, while China’s uncertainty has rather long run effects. Moreover, Bitcoin volatility responds in the same manner to US EPU and GPR, while, it responds differently to China's EPU and GPR. In extreme quantiles, we find that Bitcoin hedges against US EPU and GPR. Further, Bitcoin hedges against either individual or joint effects of US uncertainty, but not both.

Accounting practices and professional power dynamics during a crisis

This paper examines how changes in accounting practices during a crisis can affect organisational dynamics between hospital managers and clinicians. Our theoretical framework applies a multi-dimensional concept of power (Hardy, 1996) – which distinguishes power over resources, processes and meaning – to a longitudinal case study of a public university hospital during a budgetary crisis. Based on interviews with managers and clinicians, three successive time intervals with distinct power constellations are identified. Initially, we identify a pre-crisis phase where management formally controls resources, which seems to have limited effects on clinician dominance because managers lack ‘processual power’ and ‘power of meaning’. Next, an implantation phase emerges whereby the introduction of mandated budget cuts triggers shifts in the distribution of power, such that managers acquire power by securing the collaboration of clinicians – a phenomenon which has tangible benefits in terms of enabling budget compliance and increased service provision. Finally, the third phase may be conceptualized as a fiscal pressure regimen whereby, when budgetary pressures intensify further, management's newly gained ‘power of meaning’ is eroded because management are now seen to pursue unrealistic demands. Drawing on research insights gleaned during each phase, our analysis contributes to extant literature in at least three ways. First, we present novel findings regarding the impact of crises-related applications of accounting practices on intra-organisational power constellations. Second, our work highlights how accounting practices help shape the understanding of crisis, which, in turn, impacts the distribution of organizational power and influences intra-organizational patterns of collaboration. Third, we find that awareness of the meaning power of accounting practices can help shape strategic action in crisis situations.

经济法框架下的国家权力 社会经济权力 社会经济权利

人类社会从野蛮时代向国家社会的发展中伴随着社会权力向国家权力的演变。但是,在国家权力取代社会权力而对社会发展起主导性作用的同时,社会权力又有很大保留。作为社会权力中的社会经济权力在法律层面上就独立于国家权力而存在。社会经济权力存在的基础是社会公共利益的独立性及其与国家利益不同质性。国家在保护阶级利益的同时,维护确认了部分社会利益,在此基础上才形成了社会经济权利。
