Traditional models of bank runs do not allow for herding e¤ects, because in these models withdrawal decisions are assumed to be made simultaneously. I extend the banking model to allow a depositor to choose his withdrawal time. When he withdraws depends on his consumption type (patient or impatient), his private, noisy signal about the quality of the bank’s portfolio, and the withdrawal histori...

Though there are in theory linear-time algorithms for computing runs in strings, recently two of the authors implemented an O(n logn) algorithm to compute runs that was based on the Crochemore’s partitioning repetitions algorithm. The algorithm preserved the running complexity of the underlying Crochemore’s algorithm; however, the static memory requirement – already large at 14n integers for a ...

Most westerners would probably think that the roots of democracy lie in Ancient Athens, when the city state established the process by which all citizens, well, men of Athenian parentage, had an equal say in the decisions of the state. This model of ‘equally shared’ consensus decision making has wobbled, been ignored and often forgotten in intervening history but the concept has endured. But wa...

The role of sensory-motor components in language processing is a central topic in cognitive neuroscience. Recent studies showed that the processing of action words recruits cortical motor regions involved in the planning and execution of the described actions. However, it remains unclear to what extent the abstract versus concrete nature of the described motion modulates the activation of premo...
