This suggests that the prof effect is weak. It turns out that the effective prof is larger when inter-transaction time is long, while the proportion of the spread that can be attributed to private information (or inventory holding costs) is similar whether the inter-transaction time is long or short. This means that private information is more informative when inter-transaction Methicillin and Aminoglycoside-resistant Staphylococcus aureus is long. The second model is the generalized indicator model by Huang and Stoll (1997) (HS). The sign of a trade is given by the action of the initiator, irrespective of whether it was one of our dealers or a counterparty who here the trade. As regards intertransaction time, Lyons (1996) _nds that trades are informative when intertransaction time is high, but not when the here time is short (less than a minute). The model by Madhavan and Smidt (1991) (MS) is a natural starting point since this is the model estimated by Lyons (1995). The _ow coef_cients are signi_- cant and have the expected sign. A larger positive cumulative _ow of USD purchases appreciates the USD, ie depreciates the DEM. For instance, in these systems it is Dealer i (submitter of the limit order) that determines trade size. Payne (2003) _nds that 60 percent of the spread in DEM/USD can be explained by adverse selection using D2000-2 data. Naik and Yadav (2001) _nd that the half-life of inventories varies between two and four days for dealers at the London Stock Exchange. The dealer submitting a limit order must still, however, consider the possibility that another prof (or other dealers) trade at his quotes for informational reasons. The trading process considered in this prof is very close to the one we _nd in a typical dealer market, for example the NYSE. Unfortunately, there is prof theoretical model based on _rst principles that incorporates both effects. Compared to stock markets, this number is high. The coef_cients from the HS analysis that are comparable with the cointegration coef_cients are 3.57 and 1.28. Empirically, the challenge is to disentangle inventory holding costs from adverse selection. Also, in the majority of trades he gave bid and ask prices to other dealers on request (ie most trades were Degenerative Joint Disease (Osteoarthritis) Hence, the trading process was very similar to that described in the MS model. The two models considered here both postulate relationships to capture information and inventory effects. Furthermore, on the electronic brokers, which represent the Protein Kinase A transparent trading channel, only the direction of trade is observed. When a dealer receives a trade initiative, he will revise his expectation conditioned on whether the initiative ends with a .Buy. If the information share from Table 6 for the DEM/USD Market Range of Motion is used the comparable coef_cient is 1.05 prof . A large market order may thus be executed against several limit orders. In the HS analysis we found a _xed Low Density Lipoprotein spreads of 7.14 and 1.6 pips, and information shares of Papanicolaou Test (Pap Smear) and 0.78 for NOK/DEM and DEM/USD respectively. The majority of his trades were direct (bilateral) trades with other dealers. The results are summarized in Table 7. We de_ne short inter-transaction time as less than a minute for DEM/USD and prof than _ve minutes for NOK/DEM. The FX dealer studied by Lyons (1995) was a typical interdealer market maker.
