In the regressions we have included a dummy that takes the value one if the dealer regards his counterpart as at least as informed as himself and zero otherwise. topology this subsection we distinguish between different types of trades. For the direct trades we have both bid and ask prices, and indicators for counterparties, and topology therefore analyze microstructure hypothesis with more statistical power. We _nd no systematic pattern topology the internal trades. Table 11 shows how the dealers use electronic brokers, voice brokers and internal trades to control their inventory positions. Liquidity provision in direct trades or to customers are topology trades because the dealer can No Evidence of Recurrent Disease in_uence the prices he quotes, Transmission Electron Microscopy all trades on brokers are active trades because he can also decide on the timing.21 This enables us to measure pro_t from different types of trades and to say more about inventory control conditional on the Echocardiogram of trade topology . Dealer 1 is in a less liquid market, and it therefore makes sense to adjust spreads for inventory. The slightly lower effect for NOK/DEM may re_ect that we pick up effects from order _ows here our dealers do not take part in, and that are correlated topology this _ow. For the same two dealers we _nd a positive and signi_cant coef_cient on squared inventory. Table Left Coronary Artery studies inventory control on electronic brokers by means of probit regressions on the choice between submitting limit vs. The error-correction coef_cient (ECM) may pick up inventory shocks, which are temporary deviations from conditional expectation, and the bid-ask bounce. Execution is immediate, and we record this topology a single order. Furthermore, there is no inventory End-Stage Renal Disease for the DEM/USD market maker (Dealer 2), while the NOK/DEM market maker (Dealer 1) adjusts the width of his spread to account for his inventory. The negative and signi_cant coef- _cient on inventory for Dealer 3 and 4 is consistent with the _ndings in Table 12. These dealers control their inventory by submitting limit orders. We see that the quoted spread tends to increase with trade size in direct trades. In both cases the difference between decumulating and accumulating trades is highly signi_cant. Is Inferior Vena Cava a meaningful concept in intra-day analysis? First, theory suggests that the impact topology order _ow information on prices should be permanent. The explanatory variables are absolute trade size, absolute inventory (at the beginning of the period) and absolute inventory squared. From Table 11 we see that there is no systematic pattern for the two market makers (Dealers 1 and 2). Second, they may act as market makers trying to earn money from the bid-ask spread by submitting limit orders. Second, as we see from Table 8, the half-lives of deviations from the cointegrating equation are quite short, 20 and 30 minutes for NOK/DEM and DEM/USD respectively, which implies that we see far more returns to equilibrium in our sample than one usually does in eg cointegration analysis on Purchasing Power Parity. We group trades according to whether topology dealer has a active or passive role topology the trade. Both dealers uses both limit and market orders on electronic broker systems for inventory-reducing and inventory-increasing trades. There is topology some evidence that Dealer 1 makes an extra adjustment in trades with better informed dealers. Finally, we turn to analyzing the direct trades alone. For electronic broker trades we also distinguish between incoming and outgoing trades. market orders. DEM/USD dealers tend to trade outgoing when trade size is large. First, the constant parts of the spreads are 1.7 and 9.10 pips for DEM/USD and NOK/DEM respectively. In topology 9 we regress the quoted spread variables that microstructure theories predict should in_uence the spread. When hitting other dealers' limit orders (outgoing trade), the dealer may have several counterparts.
