We investigate the impact of information sharing between rivals in a dynamic auction with asymmetric information. Firms bid in sequential auctions to obtain inputs. Their inventory of inputs, determined by the results of past auctions, are privately known state variables that determine bidding incentives. The model is analyzed numerically under different information sharing rules. The analysis ...

Agents in two-sided matching games vary in characteristics that are unobservable in typical data on matching markets. We investigate the identification of the distribution of these unobserved characteristics using data on who matches with whom. The distribution of match-specific unobservables cannot be fully recovered without information on unmatched agents, but the distribution of a combinatio...

Security properties such as confidentiality and authenticity may be considered in terms of the flow of messages within a network. To the extent that this characterisation is justified, the use of a process algebra such as Communicating Sequential Processes (CSP) seems appropriate to describe and analyse them’. This paper explores ways in which security properties may be described as CSP specifi...

Berry, Levinsohn and Pakes (1995), or BLP, introduce a widely-used estimator that handles market-level demand shocks and price endogeneity in structural discrete choice demand models. This estimator is necessary to work with demand data from differentiated products industries. The estimator is computationally intensive and difficult to program, largely because a system of market share equations...
