At a given point in time, bitcoin prices are different on exchanges located in different countries, or against different currencies. While existing literature attributes the largest price differences to frictions, like market segmentation, trading platforms advertize how to execute trades based on this information. We provide a novel risk-based explanation of these price differences for a sample containing the most reputable exchanges and after accounting for all transaction costs and limitations to trade. Bitcoin prices for more expensive pairs are riskier because they depreciate more in bad times for cryptocurrency investors, when aggregate liquidity and investor sentiment are lower.

This paper focuses on emerging market government bonds issued in local currency with different maturities. Foreign investors face interest rate, currency, and credit risks. We consider the entire term structure of carry trade returns and find that, while the default premium does not contribute to carry trade strategies, the contribution of interest rate risk, captured by the term premium, is large and increases with maturity. We introduce default risk in an otherwise standard affine model; we show that the volatility of the permanent component of the SDFs must be different across emerging markets in order to match these stylized facts.
