Price inconsistency between Bitcoin Exchanges has been widely observed and documented. Using Author’s self-collected daily panel data for 22 Bitcoin exchanges under 11 currencies, this study empirically examines the effect of regulation changes on Bitcoin cross country premium. To measure Bitcoin regulation changes, this study constructs an original country level Bitcoin regulation news index. Web crawler (scripted by author using Python) is used to collect Bitcoin regulation related reporting from news websites like CNBC, Reuters and Coindesk etc. Results of this paper suggest that tighter relative regulation increase level of market segmentation, which induce higher premium. By investigating the effect of each type of news individually, warning news and formal news are found to be the main driver of the result, and formal news have higher estimated effect on premium. This paper also identify the spillover effect from regulation change in other countries. Country’s Bitcoin premium is increasing as other countries tightening their Bitcoin regulations
Price Convergence of Bitcoin: a VECM Study
This paper studies the speed of convergence of Bitcoin across markets globally to find supportive evidence for LOOP. Data used for this study is minute level high frequency data from April 25th 2018 to April 9th 2019 collected by author from 16 major Bitcoin exchanges’ API using python scripts. This study uses VECM model and estimates half-lives of Bitcoin price convergence across markets. The estimated half-lives of Bitcoin price convergence are in terms of minutes, which are significantly faster than past LOOP literature on commodity and other financial assets. This is a supportive empirical evidence for LOOP theory. This study also discovers that the speed of convergence for Bitcoin traded in Asia currencies is significantly slower than Bitcoin traded in European and North American currencies, which provides evidence for market segmentation.
Exchange Rate Volatility and Economic Growth: Importance of Access to Credit
( Available Soon )
This paper empirically tests the effect of country’s domestic and international credit access on effect of exchange rate volatility on growth. This study uses annual panel data from 2003 to 2015 for 115 countries. System GMM estimation with two step standard error is used for regression analysis. Country’s financial development level is used to measure country’s domestic credit access, and country’s foreign bank presence level is used to measure country’s international credit access. This study finds that countries with higher level of financial development are less likely to be adversely affected by exchange rate volatility, and higher level of foreign bank presence can ameliorate the adverse growth effect of exchange rate volatility. The result of this paper implies that countries with high levels of credit access can use more flexible exchange rate regime since countries’ high credit access helps to insulate the economy from the adverse effect of exchange rate volatility. For countries with low credit access, exchange rate stability is important for economic growth so that it is preferable to use the fixed exchange rate regime.
