We give a simplified proof of regularizing effects for first-order Hamilton-Jacobi Equations of the form ut+H(x, t, Du) = 0 in R ×(0,+∞) in the case where the idea is to first estimate ut. As a consequence, we have a Lipschitz regularity in space and time for coercive Hamiltonians and, for hypo-elliptic Hamiltonians, we also have an Hölder regularizing effect in space following a result of L. C...

In a laboratory experiment we show that minimum wages have significant and lasting effects on subjects’ reservation wages. The temporary introduction of a minimum wage leads to a rise in subjects’ reservation wages which persists even after the minimum wage has been removed. Firms are therefore forced to pay higher wages after the removal of the minimum wage than before its introduction. As a c...

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...

Interchange is essential in a metro network. Regarding the seismic performance, series of large-scale shaking table tests were performed on an interchange station. The station was composed two-story section rigidly connected to perpendicular three-story section, leading abrupt change stiffness conjunction area. Synthetic model soil (a mixture sand and sawdust) granular concrete with galvanized ...

Future wireless communication base-station receivers need to use sophisticated algorithms to support extremely high data rates and multimedia. A direct implementation of these algorithms on DSPs fails to achieve real-time requirements. Therefore, these algorithms need to be modified for an architecturefriendly solution. Also, several features present in wireless communication algorithms, which ...

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...
