Multi-Priority Patient Transfer Under Ambulance Offload Delay
Ambulance offload delays occur when emergency medical service (EMS) personnel are unable to promptly transfer patients to overwhelmed emergency departments. These delays postpone necessary care for the patient and hinder the EMS system from attending to new emergencies. This study introduces a real-time multi-priority patient transfer policy aimed at reducing these delays. We model the patient transfer problem as a stochastic dynamic program based on post-decision states, and develop approximate

The Impact of Customer Information on Service Supply and Demand: Evidence from a Large Live-Streaming Experiment
Problem definition: As digitization transforms the service sector and empowers service platforms, questions arise about utilizing and disseminating customer information captured by digitization to enhance platform operations. We contribute by investigating how providing customer-related information at the start of a service encounter impacts both service supply and demand in the context of entertainment service platforms. Methodology/ results: We conducted a field experiment on a live-streaming

Monetary policy in open economies with production networks
This paper studies monetary policy design in small open economies with cross-border and input-output linkages. We derive the divine coincidence (DC) Phillips curve linking the output gap to a DC index that weights each sector's inflation by sectoral contents in domestic consumption and exports, and of domestic labor. Output gap targeting can be implemented by stabilizing the DC index, which assigns larger weights to sectors that supply more inputs directly or indirectly to domestic output an

Beyond Lost Earnings: Job Displacement and the Cost of Commuting
We examine the impact of involuntary job displacement on workers' commuting behavior and its implications for the overall welfare cost of job loss. Using geo-referenced employee-employer data from Germany (2000-2017), we track workers' door-to-door commuting and relocation patterns between home and work. After displacement, workers commute 23.1% (3.38 kilometers) farther to new jobs, and the effect diminishes over time due to job changes rather than home relocation. The simultaneous wage

Whispers in Your Mind: The Role of Voice Features in Customer Acquisition and Retention
While most marketing studies have focused on what salespeople say, less is known about the persuasiveness of how they say it, particularly in the distinct contexts of customer acquisition and retention. This research investigates how salespeople's vocal brightness and loudness influence new and existing customers' purchase behavior. Based on two studies conducted in China (a field study using a large real-world dataset of over 8,000 telephone calls and a randomized controlled experiment)

From an Interior Point to a Corner Point: Smart Crossover
Identifying optimal basic feasible solutions to linear programming problems is a critical task for mixed integer programming and other applications. The crossover method, which aims at deriving an optimal extreme point from a suboptimal solution (the output of a starting method such as interior-point methods or first-order methods), is crucial in this process. This method, compared with the starting method, frequently represents the primary computational bottleneck in practical applications. We
