We explore the co-explosive dynamics between Bitcoin’s price and these factors. Using weekly data spanning from October 4, 2013, to September 24, 2021, the research uncovers a four-explosive-root relationship with Bitcoin’s price. Our primary emphasis is on the interaction between Bitcoin’s price and Google search interest. Enhanced Google search activity is correlated with an increase in Bitcoin’s price in the long term. The Bitcoin price and Google search volumes adjust to long-term deviations from their established relationship, classifying them as explosive variables. This behavior of Bitcoin’s price is consistent with existing literature that highlights its inherently explosive nature.</div></div>","PeriodicalId":11468,"journal":{"name":"Economics Letters","volume":"246 ","pages":"Article 112072"},"PeriodicalIF":2.1,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was followed by a substantial movement away from market topics towards topics related to civil society. We associate the first shift with the mathematical formalization of the Marshallian paradigm. The subsequent increased attention to civil society coincided with novel research questions and empirical methods including experiments and the use of large datasets.

The approximate value of the model’s anchoring measure can be inferred from observable data generated by the model itself, as given by 1 minus the autocorrelation statistic for quarterly inflation.
