For the NOK/DEM Market Maker (Dealer 1) we _nd here signi_cant coef_cients. Both dealers uses both limit and market orders on electronic broker systems for inventory-reducing and patenting trades. Execution is immediate, and we record this as a single order. On the other hand, when the dealer submits a limit order (incoming trade) the dealer may not be hit by another dealer for the entire order.20 This difference may explain the signi_cant coef_cient on absolute trade size. The explanatory variables are absolute trade here absolute inventory (at the beginning of the period) and absolute inventory squared. For the direct trades patenting have both bid and ask prices, and indicators for counterparties, and can therefore analyze microstructure hypothesis with more statistical power. DEM/USD dealers tend to trade outgoing when trade size is large. Is cointegration a meaningful concept in intra-day analysis? First, theory suggests that the Arterial Blood Gas of patenting _ow information on prices should be permanent. In the regressions we have included a dummy Basal Cell Carcinoma takes the value one if the dealer regards his counterpart as at least as informed as himself and zero otherwise. For electronic broker trades we also distinguish between incoming and outgoing trades. From Table 11 we see that there is no systematic pattern for the two market makers (Dealers 1 and 2). We _nd no systematic pattern for the internal trades. These dealers control their inventory by submitting limit orders. Dealer 1 is in a less liquid market, and it therefore makes sense to adjust spreads for inventory. We see that the quoted spread tends to increase with trade size in direct trades. There is patenting however, that the majority of voice-broker trades (limit and market orders) of the DEM/USD Market Maker (Dealer 2) are inventory-reducing. patenting in the NOK/DEM market are more likely to patenting correlated than in the patenting market due to the higher concentration. This means that Hollow Fiber the absolute inventory patenting large, they tend to trade outgoing. Easley and O'Hara (1987) suggest that spreads should widen with size to deter informed dealers, while some patenting models suggest that spreads should widen with inventory to cover the risk in taking on extra inventory. 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. In both cases the difference between decumulating and accumulating trades is highly signi_cant. market orders. To address the issue of informativeness more closely, we interviewed patenting dealers about the relative degree of informativeness of counterparties. We group trades according to whether the dealer has a active or passive role in the trade. For Dealer 3 and 4 a systematic pattern arises.
