Job Insecurity
研究了固定工资下工作保障与生产力的关系，发现工作不安全感与生产力呈U形关系，即中等保障时工人生产力最低。
We examine the relationship between job security and productivity in a fixed wage workerfirm relationship facing match quality uncertainty. The worker’s action affects both learning and current productivity. The firm, seeing worker behavior and outcomes, makes a firing decision. As bad news accrues, the firm cannot commit to retain the worker. This creates perverse incentives: the worker strat egically slows learning, harming productivity. We fully characterize the unique equilibrium in our continuous time game. Consistent with some evidence in organizational psychology, the relationship between job insecurity and productivity is U shaped: a worker is least productive when his job is moderately secure.
