This Test Guideline is used in the assessment and evaluation of the toxic effects of organophosporus substances. Daily doses of the test substance are administered orally (preferably by gavage or administration of gelatin capsules) to domestic laying hens (aged 8 to 12 months) for 28 days. The...

We study the effects of consumer information on equlibrium market prices and observable product quality in the market for child care. Child care markets offer a unique opportunity to study these effects because of the existence of resource and referral agencies (R&Rs) in some markets. R&Rs...

This paper develops a theoretical foundation for the social cost of carbon (SCC). The model highlights the source of debate over whether countries should use the global or domestic SCC for regulatory impact analysis. I identify conditions under which a country's decision to internalize the...

We study the optimal provision of insurance against unobservable idiosyncratic shocks in a setting in which a benevolent government cannot commit. A continuum of agents and the government play an infinitely repeated game. Actions of the government are constrained only by the threat of reverting...

We provide a new model that generates persistent performance differences amongst seemingly similar enterprises. Our model provides a mechanism whereby efficient incumbent rivals can give permission for an inefficient firm to exist in the presence of efficient entrants. We demonstrate that, in a...

Though economists have made substantial progress toward formulating theories of collusion in industrial cartels that account for a variety of fact patterns, important puzzles remain. Standard models of repeated interaction formalize the observation that cartels keep participants in line through...

Existing learning models attribute failures to learn to a lack of data. We model a different barrier. Given the large number of dimensions one could focus on when using a technology, people may fail to learn because they failed to notice important features of the data they possess. We conduct a...

A vibrant literature has emerged that suggests willingness to pay and willingness to accept measures of value are quite different for inexperienced consumers but that value differences erode with market experience. One potential shortcoming of this literature is that market experience is...

We introduce the possibility of direct punishment by specialized enforcers into a model of community enforcement. Specialized enforcers need to be given incentives to carry out costly punishments. Our main result shows that, when the specialized enforcement technology is sufficiently effective,...

This paper analyzes dynamic oligopoly models where investment is the principal strategic variable of interest, there are a large number of investment choices, and there are privately observed shocks to the marginal cost of investment. We show that simulation methods to compute these models can...
