We study the decisions of state-chartered banks to join Fed in its first decade. Ours is combine state regulatory environment characteristics and individual bank explain membership choice. Regulatory environments that reduced benefit discount window access or increased cost joining led fewer joining. Individual affected magnitude benefits from accessing (either passing on liquidity risk reducti...

Continuous queries over data streams have gained popularity as the breadth of possible applications, ranging from network monitoring to online pattern discovery, have increased. Joining of streams is a fundamental issue that must be resolved to enable complex queries over multiple streams. However, as streams can represent potentially infinite data, it is infeasible to have full join evaluation...

We present experiments exploring why high ability workers join teams with less able coworkers when there are no short-term financial benefits. distinguish between two explanations: prosocial preferences and expected long-term gains from teaching future teammates. Participants perform a real-effort task decide whether to work independently or two-person team. Treatments vary the payment scheme (...

In this paper we experimentally study the performance of main-memory, parallel, multi-core join algorithms, focusing on sort-merge and (radix-)hash join. The relative performance of these two join approaches have been a topic of discussion for a long time. With the advent of modern multicore architectures, it has been argued that sort-merge join is now a better choice than radix-hash join. This...
