We take this question to be isomorphic to, "What Keeps Fixed Exchange Rates Fixed?" and address it with analysis familiar in exchange-rate economics. Stablecoins solve the volatility problem by pegging to a national currency, typically the US dollar, and are used as vehicles for exchanging...

This paper examines whether currency trading volume is informative, and under what circumstances. Specifically, we use transactions data to test whether trades occurring when trading intensity is high are more informative - dollar for dollar - than trades occurring when intensity is low. Theory...

This paper introduces a three-part transactions dataset to test various microstructural hypotheses about the spot foreign exchange market. In particular, we test for effects of trading volume on quoted prices through the two channels stressed in the literature: the information channel and the...

This paper addresses the issue of optimal transparency in a multiple-dealer market. In particular, we examine the question: Would risk-averse dealers prefer ex-ante that signed order flow were observable? We answer this question with the solution to a mechanism design problem. The resulting...

An information externality exists in the foreign exchange market due to the fact that traders play two partially conflicting roles: (i) each is a speculator and (ii) each is an information clearinghouse in that each intermediates own-customer orders which convey information. Profit maximization...

I test three potentially complementary models in an effort to capture the fundamentals that underlaid the market's determination of Peru's floating exchange rate through the period 1950-54: the first is an expectational purchasing power parity (PPP) model which maintains that asset market forces...

Using the sticky price monetary model of exchange rate determination and the sunk cost model of trade hysteresis, we show that a sufficiently large policy misalignment can induce hysteresis in the trade balance and thereby alter the steady?state real exchange rate. Thus in our model exchange...

This paper addresses currency competition from an information perspective. Transactions in traditional models do not convey information, so transaction costs -- the driver of competition outcomes -- are driven by market size. In our model transactions do convey information (consistent with...

This paper compares the true, ex-ante forecasting performance of a micro-based model against both a standard macro model and a random walk. In contrast to existing literature, which is focused on longer horizon forecasting, we examine forecasting over horizons from one day to one month (the...

This paper addresses whether macro news arrivals affect currency markets over time. The null from macro exchange-rate theory is that they do not: macro news is impounded in ex-change rates instantaneously. We test this by examining the effects of news on subsequent trades by end-user...
