Information and Trading on Electronic Communications Networks
The differences between ECNs and Nasdaq market makers are used to formulate and test several hypotheses about the choice of trading venue and the importance of ECN trades in the price discovery process. Trades are more likely to occur on ECNs when spreads are narrow and when trading volume and stock-return volatility are high. Medium and large trades on ECNs have lower effective spreads than co...

متن کاملSpace Weather Support for Communications
Ionospheric variability (space weather) significantly impacts ground and space-based communications. In essence, the electrically charged particles of the ionosphere (i.e., the partially ionized portion of the atmosphere starting at about 40 nautical miles (nm) above the Earth's surface) can attenuate, totally absorb, reflect, change direction of propagation, and change the phase and amplitude ...
متن کاملContributions of Agricultural Systems Modeling to Weather Index Insurance
Climate exerts a profound influence on the lives of rural populations, particularly the rural poor, who depend on agriculture for livelihood and sustenance, who are unprotected against climate-related diseases, who lack secure access to water and food, and who are vulnerable to hydrometeorological hazard. Climate shocks such as drought and flooding lead not only to loss of life, but also long-t...
