The problems involving incentive compatibility constrains in the form of participation constrains have received wide attention in the literature due to the recent advances in the dynamic optimization techniques. Often the optimality conditions for this class of problems involve partial derivatives of the optimal value function with respect to some of the endogenous state variables. In this note...

Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses. Yet, as this demonstrates, also allows us observe in prevalence discourses texts patterns keyword co-occurrence. Metadata c...

Keyword search over structural data enables users to seek information from databases without knowing the structure of data or mastering actual query languages like SQL. In a keyword query, data items or text attributes are matched to the keywords and the result of a query is typically a set of graphs consisting of connected tuples. The result should be ranked which means that the text attribute...

Motivated by sponsored search auctions, we study multi-unit auctions with budget constraints. In the mechanism we propose, Sort-Cut, understating budgets or values is weakly dominated. Since Sort-Cut’s revenue is increasing in budgets and values, all kinds of equilibrium deviations from true valuations turn out to be bene…cial to the auctioneer. We show that the revenue of Sort-Cut can be an or...
