Time Allocation and Task Juggling
研究单个工人在多个项目间分配时间时，同时处理过多项目会降低产出率并延长完成时间，这种现象称为“任务切换”，并分析其与工人努力的关系及客户游说导致的任务切换模型。
A single worker allocates her time among different projects which are progressively assigned. When the worker works on too many projects at the same time, the output rate decreases and completion time increases according to a law which we derive. We call this phenomenon “task juggling” and argue that it is pervasive in the workplace. We show that task juggling is a strategic substitute of worker effort. We then present a model where task juggling is the result of lobbying by clients, or coworkers, each seeking to get the worker to apply effort to his project ahead of the others’.
