We study markets for a good whose safety (the seller’s type), cannot be costlessly observed by the buyer. Using a costly state verification model with inter-temporal correlation in types, we identify contractual arrangements that induce sellers to report unsafe products voluntarily. Perfect, but costly, verification (audits) and an exogenous publicly provided noisy signal (forecast) can provide...

The development of markets for natural resources can help to ensure that individual users appropriately internalize the opportunity cost of these resources and thus can decrease resource use. However, expansion of markets also makes it possible to sell these resources, which may lead to more rapid extraction. A simple model of markets for groundwater suggests that the latter effect dominates an...

When parallel applications are run in large-scale distributed environments, such as grids, peer-to-peer (P2P) systems, and clouds, the set of resources used can change dynamically as machines crash, reservations end, and new resources become available. It is vital for applications to respond to these changes. Therefore, it is necessary to keep track of the available resources—a problem which is...
