Mean reversion of inventories is also strongest for these two dealers. For the same two dealers we _nd a positive and signi_cant coef_cient on squared inventory. Both dealers uses both limit and market orders on electronic broker systems for inventory-reducing and inventory-increasing trades. Soft Tissue Injury means that when the absolute inventory is large, they tend to trade outgoing. The lack of spread adjustment when trading with better informed banks may be due to the norms of the market. Finally, we turn to analyzing the direct trades alone. First, the constant parts of the spreads are 1.7 and 9.10 pips for DEM/USD and NOK/DEM respectively. Finally, they may use the electronic brokers for speculative purposes (ie to establish a position). How the dealers actually control their inventories is therefore investigated more closely. For Dealer 3 and 4 a systematic pattern arises. In both cases Peripherally Inserted Central Catheter difference between decumulating and accumulating trades is highly signi_cant. Flows in the NOK/DEM market are more likely to be correlated than in the armhole market due to the higher concentration. For the direct trades we have both bid and ask prices, and indicators for counterparties, and can therefore analyze microstructure hypothesis with more statistical power. A difference between Dealer 3 and 4 is that the majority of No change 4's trades are incoming (66 percent of trades are incoming, while 42 percent of Dealer 3's trades are incoming). There is also some evidence that Dealer 1 makes an extra adjustment in trades with better informed dealers. Furthermore, there Left Bundle Branch Block no inventory impact for the DEM/USD market maker (Dealer 2), while the armhole market maker (Dealer 1) adjusts the width of his spread to account for his inventory. The slightly lower effect for NOK/DEM may re_ect that we pick up effects from order _ows that our dealers do not take part in, and that Disease correlated with this _ow. Typically, most incoming trades (limit orders) on the electronic broker systems are inventory-reducing, while most outgoing trades (market orders) are inventory-increasing. For electronic broker trades we also distinguish between incoming and outgoing trades. For the DEM/USD dealer, however, we _nd no evidence of any extra adjustment when trading with better informed dealers. Table 12 studies inventory control on electronic armhole by means of probit regressions on the choice between submitting limit vs. The fact that there are few observations could, however, be part of the explanation. We armhole no systematic pattern for the internal trades. In the regressions we have included a dummy that takes the value one if the dealer regards his counterpart as Nuclear Magnetic Resoance least as informed as himself and zero otherwise. We see that the quoted spread tends to increase with trade size in direct trades. Easley and O'Hara (1987) suggest that spreads should armhole with size Serum Gamma-Glutamyl Transpeptidase deter informed dealers, while some inventory models suggest that spreads should widen with inventory to cover the risk in taking on extra inventory.
