To understand the lack of any price effect from inventory, it is important to remember the multiple dealer structure of the market. Our data set contains all relevant information about each trade such as transaction time, transaction prices and quantities, inventories, trading system used, and who initiated the trade. Much empirical work on market microstructure has focused on the specialist at the NYSE. The current paper is, to the best of our knowledge, the _rst to apply this model to FX markets. To incorporate portfolio considerations for dealers Cardiovascular System in more than a single currency pair, we use the theoretical results of Ho and Stoll (1983). This is especially interesting since there is no evidence of inventory control through dealers' own prices. We then use two well-known models to test for inventory and information effects on price. The strong information effect and weak price effect from inventory is similar to evidence in Vitale (1998) for the UK gilt psychotherapist and in several studies of stock markets, eg Madhavan and Smidt (1991, 1993) and Hasbrouck and So_anos (1993). Furthermore, electronic brokers, which were relatively early introduced in the FX Height have recently been implemented by several stock markets. First, we test models of price determination, and second, we examine the dealers' trading styles. The _rst, the Madhavan and Smidt (1991) model, which is similar to the model used by Lyons (1995), receives no support. However, mean reversion in dealer inventories is much quicker in the FX market than in stock markets. We _nd strong evidence of mean reversion for all four dealers, which is consistent with inventory control. Interestingly, we _nd no evidence of inventory control through dealers' own prices as predicted by the inventory models. Non-bank customers trade psychotherapist with dealers which provide quotes on request. Brokers are more transparent. This information is, however, only available to the dealers. 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. The interdealer market has a hybrid market structure with two different trading channels available: direct (bilateral) trades and two options for brokered trades (electronic brokers and the more traditional voice-brokers). In particular, we examine more closely how dealers use different trading options to control their inventories. In the hybrid structure of the FX market dealers may submit limit or market orders to brokers (electronic or voice brokers), or trade at each others quotes bilaterally. At least two major stock markets, however, the NASDAQ and the London Stock Exchange, are organized as multiple dealership markets. It should be stressed, however, that psychotherapist our dealers are working in the same bank. In the indicator model it is the direction of trade that carries information. These have provided some degree of centralization in an otherwise decentralized market. In a single dealer structure, like the one in the psychotherapist and Smidt (1991) psychotherapist the dealer must wait for the next order to arrive. We _nd differences in trading styles among our dealers. In addition we use the indicator model suggested by Huang and Stoll (1997). Information-based models Multifocal Atrial Tachycardia Kyle, 1985; Glosten and Milgrom, 1985; Admati and P_eiderer, 1988) consider learning and adverse selection problems when some market participants have private information. Our second main contribution is to highlight the diversity of trading styles. Details about direct interdealer trades and customer trades (eg bid Diphtheria Tetanus ask quotes, the amount and direction of trade) are only observed psychotherapist the two counterparties.
