This study back-tests a marginal cost of production model proposed to value the digital currency Bitcoin. Results from both conventional regression and vector autoregression (VAR) models show that the marginal cost of production plays an important role in explaining Bitcoin prices, challenging recent allegations that Bitcoins are essentially worthless. Even with markets pricing Bitcoin in the thousands of dollars each, the valuation model seems robust. The data show that a price bubble that began in the Fall of 2017 resolved itself in early 2018, converging with the marginal cost model. This suggests that while bubbles may appear in the Bitcoin market, prices will tend to this bound and not collapse to zero.  相似文献

Forward guidance can be provided as an unconditional promise, i.e. commitment to a specific low policy rate. Alternatively, the promise may include an escape clause, i.e. a condition defining the state of the economy under which the central bank would not keep such a low rate and, instead, it would revert to setting policy under discretion. The escape clause can be expressed as a threshold in terms of a specific variable. The present paper shows that, when such a threshold is expressed in terms of an endogenous variable (e.g. output, inflation), there are cases where it becomes impossible for the central bank to act in a way that is consistent with its promise. Consistency imposes limits on the policy rate that can be set since reverting immediately to the optimal discretionary rate can be incompatible with exceeding the threshold.  相似文献

Although a growing body of literature has touted e-participation as a means of facilitating greater citizen participation in policy decision-making processes, little is known about the driving forces behind citizens’ use of e-participation. Based on a literature review of social capital and citizen participation, this study develops and tests a model proposing that three dimensions of social capital and three dimensions of citizen participation management should be positively associated with e-participation in agenda setting. Using data from a Korean e-participation survey conducted in 2009, we found that citizens tend to be more active e-participants when they have greater trust in government and are weakly tied to offline social groups. We also found that citizen participants’ perception of government responsiveness to their input can facilitate their e-participation. The study findings imply that local governments should pay more attention to the function of public trust in local government and provide quality feedback in response to citizen input. They should also be sensitive to how the social factors of e-participants can facilitate involvement in agenda setting.  相似文献
