A firm monopsonistically hires labor from a pool containing both skilled and unskilled workers. The marginal value of a worker depends on the match between the job and the worker's skill level. Unskilled workers can have negative productivity if they are placed in a skilled job. The firm cannot...

We then characterize analytically and numerically how the characteristics of private information—its quantity, persistence and correlation, and division among speculators—affect trading profits, pricing and trading strategies. In particular, we derive how speculators trade on new information...

In an economy with a continuum of individuals, each individual has a stochastic, continuously evolving endowment process. Individuals are risk averse and would therefore like to insure their endowment processes. It is feasible to obtain insurance by pooling endowments across individuals because...

A stochastic process impinges on an agent and a principal in distinct ways. From the agent's perspective the process is noise that interferes with his perception of productivity states, leading him to sometimes take actions that are in retrospect mistaken. From the principal's perspective the...

We characterize the dynamics of an industry in which demand and costs are constantly evolving so that firms are always adjusting output in response. Firms receive private information about their costs and privately observe components of demand. In addition, firms extract information from prices...
