We use a local energy method to study the spatial localization of the supports of the solutions of a reaction{ diiusion system with nonlinear diiusion and a general reaction term. We establish nite speed of propagation and the existence of waiting times under a set of weak assumptions on the structural form of the system. These assumptions allow for additive and multiplicative reaction terms an...

The purpose of this paper is to see whether and how G-10 banks have complied with the 1988 Basel Capital Accord. The interest of this study lies in the fact that the standardized approach of the New Basel Accord is similar to the 1988 agreement. However, very little is known about the reaction of non-US banks to the imposition of fixed minimum capital requirements. Building on previous studies,...

Can we detect the merger paradox in the year 1908 in Germany? An event-study method that uses daily returns in contrast to former historical research gives answers. The merger paradox is not confirmed by our data, and the adaptation process of stock prices according to newly available information is finished in a few days around the event. In addition, we use cumulated abnormal returns as depen...

In this paper we use nonparametric kernel density estimation techniques to develop a new class of smooth estimators for the parameters in SURE and simultaneous equations models. The eeciency property of the proposed estimators is also analysed. are thankful to H. L utkepohl and a referee for useful comments on the earlier version of this paper.

CDF and DØ detectors have already collected 1.3 fb−1 of data delivered by the Tevatron collider at 1.96 TeV center-of-mass energy. We present here the various analyses that are currently testing the possibility of a supersymmetric extension of the Standard Model. No evidence for such processes have been found in luminosities that range from 300 to 800 pb−1 and different limits on the different ...

Conventional work on scienti c discovery such as BACON derives empirical law equations from experimental data. In recent years, SDS introducing mathematical admissibility constraints has been proposed to discover rst principle based law equations, and it has been further extended to discover law equations from passively observed data. Furthermore, SSF has been proposed to discover the structure...

Normalized Equation and Decomposition Analysis: Computation and Inference This paper joins discussions on normalized regression and decomposition equations in devising a simple and general algorithm for obtaining the normalized regression and applying it to the Oaxaca decomposition. This resolves the invariance problem in the detailed Oaxaca decomposition. An algorithm to calculate an asymptoti...

Econometric busines cycle research (EBCR) combines economic theory and measurement in the study of business cycles, i.e., up and downs in overall economic activity. EBCR has four goals: description, forecasting, policy evaluation and implementation/testing of economic theories. In this paper I assess four EBCR methods: business cycle indicators, simultaneous equations models, vector autoregress...

Offshore wind turbines are considered as an important element of the future energy infrastructure. There is currently a surge in the construction of such facilities in Europe, yet there is no track record of long-term performance of these structures. Offshore wind turbines are dynamically sensitive structures because of the very nature of the structural form (tall and slender) and the different...
