A Contribution to the Empirics of Reservation Wages This paper provides evidence on the behavior of reservation wages over the spell of unemployment using high‐frequency longitudinal data. Using data from our survey of unemployed workers in New Jersey, where workers were interviewed each week for up to 24 weeks, we find that self‐reported reservation wages decline at a modest rate over the spel...

Consider a (robotic) explorer starting an exploration of an unknown terrain from its base station. As the explorer has only limited communication radius, it is necessary to maintain a line of robotic relay stations following the explorer, so that consecutive stations are within the communication radius of each other. This line has to start in the base station and to end at the explorer. In the ...

In this paper we examine the use of hypotheticals as a heuristic device to assist a case-based reasoner test the strengths, weaknesses, and ramifications of an analysis or argument by exploring and augmenting the space of known cases and indirectly, the at tendant spaces of doctrine and argument. Our program, HYPO, works in the task domain of the law, particularly, the area of trade secret prot...

In this paper, we empirically test the relation between price discrimination and product market competition in a two-sided market environment using a new data set of Spanish local TV stations that provides information on subscription and advertising prices per station for 1996, 1999 and 2002. Due to changes in regulation during this period affecting the degree of local market competition, we us...

7 We apply two different algorithms to measure surface-wave phase velocity, as a function of 8 frequency, from seismic ambient noise recorded at pairs of stations from a large European 9 network. The two methods are based on consistent theoretical formulations, but differ in the 10 implementation: one method involves the time-domain cross-correlation of signal recorded 11 at different stations;...

The objectives of this project are; to demonstrate that hydrographic variability in shelf waters can be hind-cast, to a quantifiable degree, using a simple 1 dimensional physical model. To demonstrate that the model can be used to interpret the regional variability of ocean colour in terms of the mechanisms of physical forcing on phytoplankton growth. The effects of tidal front dynamics and the...

The media and TV world faces new challenges such as the introduction of digital and interactive TV. In order to cope with the complexity of these new services, a well-structured back office is of prime importance. Today, efficient management of content is hampered by the proprietary formats used in the different software applications that have been developed by various vendors. Moreover, the la...

These paper introduces a reservation subframe protocol for multimedia services in a 3rd generation mobile telecommunication system. The Packet Reservation Multiple Access (PRMA) protocol is modified to achieve more efficient bandwidth management. Simulation results show that the resulting multiple access multimedia system can serve a large number of users with low probability of packet loss, en...
