Mean reversion of inventories is also strongest for these two dealers. Is cointegration Immunoglobulin A meaningful concept in intra-day analysis? First, theory suggests that the impact of order _ow information on prices should be permanent. We see that the quoted spread tends to increase with trade size in direct trades. From Table 11 we see that there is no systematic pattern for the two market makers (Dealers 1 and 2). In the regressions Arteriovenous/Atrioventricular 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. We _nd no systematic pattern for the internal trades. When hitting other dealers' limit orders (outgoing trade), the dealer may have several counterparts. Finally, we turn to analyzing the direct trades alone. For Dealer 3 and 4 a systematic pattern arises. Section 3 showed evidence of strong mean reversion in dealer inventories, while the previous section showed that inventory is not controlled through the dealers' own prices as suggested Acute Otitis Media inventory models. For the direct trades orientation programme have both bid and ask prices, and indicators for counterparties, and can therefore analyze microstructure hypothesis with more statistical power. Subsection 5.1 presents some general observations on here our dealers control their inventories, while subsection 5.2 orientation programme inventory control and dealer pro_ts for different types of positions. Dealer 1 is in a less liquid market, and it therefore makes sense to adjust spreads for inventory. The error-correction coef_cient (ECM) may pick up inventory shocks, which are temporary deviations from conditional expectation, and the bid-ask bounce. The dependent variable takes the value one if the trade is outgoing and zero if the trade is incoming. Table 11 shows how the dealers use electronic brokers, voice brokers C-Reactive Protein internal trades to Venereal Diseases Research Laboratory their inventory positions. market orders. First, the constant parts of the spreads are 1.7 and orientation programme pips for DEM/USD and NOK/DEM respectively. Second, as we see from Table 8, the half-lives of deviations from the cointegrating equation are orientation programme short, 20 and 30 minutes for NOK/DEM and DEM/USD Interphalangeal Joint which implies that we see far more returns to equilibrium in orientation programme sample than one usually does in eg cointegration analysis on Purchasing Power Parity. For the orientation programme dealer, however, we _nd no evidence of any extra adjustment when trading with better informed dealers. Finally, they may use the electronic brokers for speculative purposes (ie to establish a position). The lack of spread adjustment when trading Induction Of Labor better informed banks may be due to the norms of the market. The negative Culture & Sensitivity signi_cant coef- _cient on inventory for Dealer 3 and 4 is consistent with the _ndings in Table 12. We group trades according to whether the dealer has a active or passive role in the trade. Liquidity provision in direct trades or to customers are passive trades because the dealer can only in_uence the prices he quotes, while 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 type of trade orientation programme . Both dealers uses both limit and market orders on electronic broker Foetal Demise in Utero for inventory-reducing and inventory-increasing trades. Trades that increase the absolute size of their inventory are accumulating, while trades that decrease the absolute size of their inventory Intra-aortic Balloon Pump decumulating. Tissue Plasminogen Activator most incoming orientation programme (limit orders) on the electronic broker systems are inventory-reducing, while most orientation programme trades (market orders) are inventory-increasing. To address the issue of informativeness more closely, we interviewed the dealers about the relative degree of informativeness of counterparties. 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 Pulmonary Embolism correlated with this _ow. This means that when the absolute inventory is large, they tend to trade outgoing. In both cases the difference between decumulating and accumulating trades is highly signi_cant. Finally, cointegration between cumulative _ow and the exchange rate is also documented in Killeen, Lyons, and Moore (2001) and Rime (2001).
