Regional patterns in the law of one price: the roles of geography vs. currencies
We find evidence that the law of one price (LOOP) holds more nearly for country pairs that are within geographic regions than for country pairs that are not. These findings are established using consumer price data from 23 countries (including data from eight North American cities.) We find that failures of LOOP are closely related to nominal exchange rate variability, suggesting a link to sticky nominal prices. We also find that distance can explain failures of LOOP, suggesting the failures arise from imperfect market integration. However, these two sources do not explain all of the failures ...

Scrambling for Dollars: International Liquidity, Banks and Exchange Rates
We develop a theory of exchange rate fluctuations arising from financial institutions’ demand for dollar liquid assets. Financial flows are unpredictable and may leave banks “scrambling for dollars.” Because of settlement frictions in interbank markets, a precautionary demand for dollar reserves emerges and gives rise to an endogenous convenience yield on the dollar. We show that an increase in the dollar funding risk leads to a rise in the convenience yield and an appreciation of the dollar, as banks scramble for dollars. We present empirical evidence on the relationship between ...

Deviations from purchasing power parity: causes and welfare costs
We explore deviations from short-run purchasing power parity across European cities, attempting to move beyond a "first-generation" of papers that document very large border effects. We document two very distinct types of border effects embedded in relative prices. The first is a "real barriers effect," caused by various barriers to market integration. The second is a sticky-consumer-price cum volatile exchange-rate effect. Both are shown to be important empirically, the second type especially so. We argue that the two effects are very different from each other. For the first type of ...

Violating the law of one price: should we make a federal case out of it?
We use new disaggregated data on consumer prices to determine why there is variability in prices of similar goods across U.S. cities. We address questions similar to those that have arisen in the international context: is this variability purely a result of market segmentation or do sticky nominal prices play a role? We also examine how the degree of tradability of a good influences price variability. Surprisingly, we find that variability is larger for traded goods. We attribute this finding to greater price stickiness for non-traded goods. Distance between cities accounts for a significant ...

How wide is the border?
Failures of the law of one price explain much of the variation in real C.P.I. exchange rates. We use C.P.I. data for U.S. cities and Canadian cities for 14 categories of consumer prices to examine the nature of the deviations from the law of one price. The distance between cities explains a significant amount of the variation in the prices of similar goods in different cities. But, the variation of the price is much higher for two cities located in different countries than for two equidistant cities in the same country. By our most conservative measure, crossing the border adds as much to the ...

Intra-national, intra-continental, and intra-planetary PPP
This paper presents a general framework to address several issues that have arisen in recent work that investigates purchasing power parity (PPP) and other inter-regional relative price movements: (1) How can we model real exchange rate movements in a consistent manner, so that our model for the real exchange rate for country B relative to country C is commensurate with our models for country A/ country B and country A/ country C real exchange rates? For example, can things be modeled so that our tests do not depend on the "base country"? (2) How should we handle correlation across real ...
