Would the Social Planner Let Bags Fly Free?
Motivated by airline baggage fees, we consider a service provider offering a main service (e.g., transporting a person) and an ancillary service (e.g., transporting a checked bag) that an individual customer may or may not need. We ask whether the firm should bundle the two services and post a single price or unbundle them and price the ancillary service separately. We consider two motivations ...
متن کاملA Bioassay System for the Evaluation of Black Fly (diptera: Simuliidae) Control Agents under Simulated Stream Conditions
Can. Ent. 112: 1271-1276 (1980) A new bioassay unit is described which provides simulated stream conditions for testing control agents against black fly larvae. Attributes include uniform flow, high control survival, and excellent visibility for observing larval behavior. It also possesses the unique advantage of using recycled water, continuously supplied fresh water, both simultaneously. The ...
متن کاملPerformance of PICS bags under extreme conditions in the sahel zone of Niger
Experiments in Niger assessed whether extreme environmental conditions including sunlight exposure affect the performance of triple-layer PICS bags in protecting cowpea grain against bruchids. Sets of PICS bags and woven polypropylene bags as controls containing 50 kg of naturally infested cowpea grain were held in the laboratory or outside with sun exposure for four and one-half months. PICS b...
متن کاملMeasuring Long-Range Dependence under Changing Traffic Conditions
Recent measurements of various types of network traffic have shown evidence consistent with long-range dependence and self-similarity. However, an alternative explanation for these measurements is non-stationarity. Standard estimators of LRD parameters such as the Hurst parameter H assume stationarity and are susceptible to bias when this assumption does not hold. Hence LRD may be indicated by ...
متن کاملAerodynamic Optimization Under a Range of Operating Conditions
In aerodynamic design, good performance is generally required under a range of operating conditions, including off-design conditions. This can be achieved throughmultipoint optimization. The desired performance objective and operating conditions must be specified, and the resulting optimization problemmust be solved in such amanner that the desired performance is achieved. Issues involved in fo...
