Consumers incur many transaction costs in purchasing and using most products. This paper examines the effects of a reduction in such consumer transaction costs caused by market-level technological advances. Using a model in which consumers are simultaneously heterogenous in their transaction costs and in their marginal valuation of product quality, we highlight two mechanisms that can cause suc...

Locking is one of the predominant costs in transaction processing. While much work has focused on designing efficient locking mechanisms, not much has been done on understanding how transaction applications issue queries and leveraging application semantics to improve performance. This paper presents QURO, a query-aware compiler that automatically reorders queries in transaction code to improve...

Mobile devices that host embedded database systems are becoming a commonality. Transaction management is needed to provide mobile data availability and transaction processing functionality during disconnection periods. In this paper, we present an adaptation of the transaction correctness criterion GSI to mobile networks that reduces the number of message exchanged per transaction. We discuss t...
