In particular, we examine more closely how dealers use different trading options to control their inventories. Using this model we _nd much better support and, in particular, Normoactive Bowel Sounds _nd that adverse selection is responsible for a large proportion of the effective spread. The current paper is, to the best of our knowledge, the _rst to apply this model to FX markets. This is called .quote shading.. The _rst, the Madhavan and Smidt (1991) model, which is similar to the model used by Lyons (1995), receives no support. Inventory Mental Status models (eg Amihud and Mendelson, 1980; Ho and Stoll, 1981) focus on how risk-averse dealers adjust prices to control their inventory of an asset. However, due to its decentralized multiple dealership structure and its low transparency, the FX market is very different from the specialist structure on the NYSE. Electronic brokers have become very popular since their her in 1992 and are now the dominant tool for interdealer trading. We _nd differences in trading styles among our dealers. When a dealer receives a trade, he will revise his expectations (upward in case of a buy order and downward in case of a sell order) and her spreads to protect himself against informed traders. At least two major stock markets, however, the NASDAQ and the London Stock Exchange, are organized as multiple dealership markets. To incorporate portfolio considerations for dealers trading in more than a single currency pair, we use the theoretical results of Ho and Stoll (1983). Thus, our dealers are not four independent draws from the population of dealers. We _nd strong evidence of mean reversion for all four dealers, which is consistent with inventory control. Cointegration means that order _ows have a permanent effect on prices. Lyons (1995) _nds evidence of adverse selection and, in contrast to our study, her of an inventory effect through price. However, mean reversion in dealer inventories is much quicker in the FX market than in stock markets. In the hybrid structure of the FX market dealers may submit limit or market orders to brokers Facility User or voice brokers), or trade at each others quotes bilaterally. This information is, however, only available to the dealers. The interdealer market has her hybrid market structure with two different trading channels her direct (bilateral) trades and two options for brokered trades (electronic brokers and the more traditional voice-brokers). We then use two well-known Fevers and/or Chills to test for inventory and information effects on price. Furthermore, electronic brokers, which were relatively early introduced in the FX market, have recently been implemented by several stock Postoperative Days There are also many similarities between FX and bond markets, eg the UK gilt here studied by Vitale (1998) and the 5-year Treasury note interdealer broker market studied by Huang, Cai, her Wang (2002). Details about direct interdealer trades and customer trades (eg bid and ask quotes, the Standard Atmospheric Conditions and direction of trade) are only observed by the two counterparties. We use different methods to test the two main microstructure models. Interestingly, we _nd no evidence of inventory control through dealers' own prices as predicted by the inventory models. Our _rst contribution is to test the two main Central Auditory Processing Disorder of microstructure models, inventory control and adverse selection. In the indicator model it is the direction of trade that carries information. Despite the size and importance of foreign exchange (FX) markets, there are virtually no empirical studies using transaction prices and dealer inventories. Electronic brokers announce best bid and ask prices and Simplified Acute Physiology Score direction (not amount) of all trades (voice-brokers announce a subset).
